1967 M715 "Project Jungle Rot"

[tndonor]

Well my dream is being realized. After having the J10 with a Cummins 4B, I ran across several M715s scattered across the southest I couldnt pass up. This is the first vehicle I have ever lusted over haha.

Its time to build my dream truck.

1967 M715
95 Cummins 6BT. Oringed head, 60# valve springs, 4K governor springs, 5 x 0.18 injectors, compound turbos (hx35/HT3B), KDP, new seals, advanced timing

NV4500. Southbend 550 HP clutch, HD hydraulics

203/205 doubler (ford)

1979 Ford Dana 60 front axle. OX Locker. 4.56. 35 spline outers. Drive flanges. 9/16 wheel studs to match GM rear. 1410 yoke

14 Bolt from M1008 (4.56, detroit). Disc brake conversion. 1410 yoke. Pinion guard.

Whole mess of other things and trinkets

[tndonor]

Here is the truck pulled into my friends shop for dismanteling. Took 4 hours to pull the front sheet metal, winch, engine, and trans.

Redoing the rear suspension. The rear shackle hangers are modified GM units. The frame was plated and bolted to hold the springs. Overbuilt may be a common thread in this build.

Work keeps me mired most of the time but Ill update as I can.

Let the comments fly goo, bad, or ugly

[Headhoncho]

Looks like you're singlehandedly going to jumpstart the economy! :eek: I guess you'll be recieving lots of Christmas cards this year.

Looks great so far but why did you inboard the rear springs to inside the frame and not under it?


JR

[tndonor]

It feels like I have done my part to stimulate the economy haha. I inboarded to the springs for better articulation (thats my hunch) but mainly to keep down on lift. The 715s will clear a 38 inch tire stock. If I inlined the springs with a spring over, it would be huge and be large enough for a 46 or 49 I imagine). Spring over is the only option for what I want. Spring unders have their place, just not for this build.

Cant have the springs digging in the dirt when I show up at the tractor pulls either!!!

[newtojeeps]

Are you going to rust proof the frame? You have only to remove the cab and take it for a galvi dip before paint and under coat. Or are you waiting to finish fabbing motor , tranfer case, and spring perches. At any rate have fun.

[Gambler68]

Whoah...nice job.

What did the 14b come out of? What do you think you have into it to convert to disc? Would it still be wide enough with outboard springs? Check my build link and you'll see why I ask. TIA!

[tndonor]

I will be taking the cab off when all the mounts and crossmembers are complete. It will be getting a rust treatment/barrier applied. Kinda silly not to when its down that far. Only four bolts from the cab comming off.

[jMedia]

Are you using the ht3b as your only turbo or doing a twin turbo setup? Just looked into the ht3b and people are saying it takes a lot of fuel to get it spinning if it is your only one

[tndonor]

Gambler,

From what I recall, you must use a van width 14bolt to use outbaord springs. There are rare as far as 14 bolts go. Even still, the space between drum and spring is close.

The 14 bolt is from a CUCV. the disc brake brackets are about 50 bucks from several people. Rotors and hardware are another 150 or so new (or at least for me at NAPA).

[tndonor]

HT3B is the large turbo in the compound setup (commonly are somewhat incorrectly referred to as twins). The stock hx35 and HT3B will work together. It has the 26cm housing. It would be very difficult to spool as a single. It would take lots of fuel and lots of RPMs to acheive that. Theses turbos come off of big rigs for reference.

Twins, one turbo for each bank
Compounds, small turbo exhaust fed into larger turbo, large turbo compressed air fed into small turbo, small turbo connected to intercooler/motor.

Oh ok I see, I missed that. Since the small turbo is feeding the large, will it still take a while to spool both up? Whats the advantage of compound turbos vs twin?
Sorry for flooding your thread with ?s

[iroc86]

Looks like a really cool project. I like your plate/sleeve spring hanger idea -- I used the same method to drill holes through the frame of my YJ and it made life a lot easier.

It will be neat to follow this thread. You're building what a modern M715 should be. :)

jMedia, compound turbocharger setups are popular on diesel engines because you're usually working with a single bank of cylinders (inline configuration), making twin turbos inappropriate. Compound turbos allow you to produce much higher intake pressure than a single turbo -- the turbo sizes are matched to their respective operating ranges. The smaller turbo spools up faster, so it receives exhaust pressure first. However, since it's a smaller unit, it can generate a greater pressure (compared to the larger turbo) and is second to receive the intake pressure -- the larger turbo pressurizes the ambient air before it's pressurized again by the smaller turbo.

The operation is very similar to a dual-stage air compressor. A larger primary piston feeds a smaller secondary piston, creating a greater output pressure than a single piston by itself.

[tndonor]

Thanks iroc....great summation

Im hoping for about 60 psi of boost. Any more and the HP levels will make me get a twin disc clutch and bigger trans input.....not to say that wont happen soon!

[Etcetera]

Put a fitting in your turbo air piping from turbo to manifold to a check valve and into a tank and you have low pressure on board air.

[mattmopar440]

Keep us Updated Looks Great so far :thumbsup:

[tndonor]

Put a fitting in your turbo air piping from turbo to manifold to a check valve and into a tank and you have low pressure on board air.

While a novel idea, it will not work for an OBA setup. Exhaust tempteratures are up to 1300 degrees and when that cools (in a tank) the psi will drop as the air cools.

I need the psi and seperate system to inflate tires and run air tools, etc

I think he's talking about the air side. Although you probably won't be going much over 30-40psi, and I'm not sure how useful such low pressure would be.

[Josh D]

Off the hook cool project and being done right!!:thumbsup: I'll enjoy watching the progress!

[sportsidedan]

great project... would love those axles on my kaiser...

Yeah, mostly just joking around. Air side.

Cool project.

[tndonor]

No worries.....I joke too often and it is OFTEN taken the wrong way or as fact. Just didnt want to give a "pirate" response......this is a great community and the only way we learn is through others patience and time.

Thanks for the nods

ARP studs for the steering arms are in. LED turn signals for the front (the stock 715 are slits at best, want oncomming traffic to know my intentions because I would roll right over them without much trouble haha) Safety and the safety of others is paramount.

About to send J10 steering box off for a rebuild (unless someone can chime in and say its not difficult). I am going to use a hydraulic pump from a Cummins to push about 12-15 gallons per minute at 1750 psi....that should steer things ok. Debating on a hydraulic winch since I have the capacity.

Line locks are in for trail parking.

Pondering over using cable shifters for the doubler or having three sticks....There are going to be all kinds of levers in the cab nv4500 shifter, OX locker, 3 for the doubler haha.

[Smiff]

Great looking project! Where did you find the MRAP seats? They look perfect for a trail rig/DD. I can't wait to do a complete tear down/build up on my GW. It'll probably have to wait until I retire....:rolleyes:

I would look for a J20 box.

[tndonor]

Ive looked for them. Havent found an oring style yet. Ill drill and tap it for hydro assist so Im thinking it really wont matter as much as the hydraulic pump would.

[elij10travis]

:D nice ride thatll be worth some good cash one of these days

[tndonor]

I found the MRAP sets on another forum.

I may have a lot of $$$ going into this but this is my dream vehicle. There will never be a FOR SALE sign on it!!! When I die, theymay as well strap me in it, kick it in neutral and bury us haha

[billyrb]

awesome build, can't wait to see it done. Is Scott at TNDiesel doing the work? Still wish I had that Green J10 of yours....

Love the M715's. Awesome project. Love to see it getting done right and in style. Your seats are very cool and look like they cost a pretty penny.:thumbsup:

Everyone says how tight the 6B is in a Jeep. Well I dont think this applies to the 715 at least. Mockup gave 2 inches from the rear of the engine block to the fire wall. Once the original radiator supports are cut, I have 10 inches, minus 2.5 for the electric fan for the radiator and intercooler, that was about the same in the 95 ram I pulled this from!

ok so where in k town are you cause im in oak ridge just askin.

[tndonor]

The truck is off of 640. I would love to meet some of the fellow FSJers here but I cant get the truck out until the drivetrain swap is done. My friend and I are doing the build and he is looking at Cummins conversion swap kits for us Jeep nuts.

He has had his mounts and stuff ripped off by some big and respected 4x4 companies so out of respect for his business and paycheck, I will not have the truck out until it is roadworthy. He is a good friend of mine and want ot protect him....not that this is a bad crowd but he has been burned too many times and I wont jeopardize what he does or make him feel uncomfortable.

When its done....we can have a drool fest and swap stories, go for trail rides, talk Cummins conversions (I have had a 4B swap in a J10 as well) to our hearts content.

Thanks to all who have followed this build with excitiment. I am doing this as it is my dream build but it helps to be appreciated by everyone else here!

Ill update as much as I can. Hopefully Summer will be filled with black smoke dreams with the locals. I do travel quite a bit to Nashville, Memphis, Birminham AL, and Lake Keowee SC, Cincinatti, OH. If anyone is along the way, Im always game for talking shop to break the trips up!

[tndonor]

?

Yes Scott has a hand in this one. May be developing some Cummins conversion parts for the
FSJ crowd, we will see though:cool:

[tndonor]

Well Ive got some updates to share. After the motor was fit in and the motor mounts were made, I took a grinder to the remaining rough edges and brackets. Then I applies a rust preventative coating and shot the frame in flat black.

http://i87.photobucket.com/albums/k146/tndonor/6b.jpg

First thing was to remove everything off the top to take off the cylinder head.http://i87.photobucket.com/albums/k146/tndonor/headoff.jpg

I was very encouraged by what I found. 167,xxx miles

http://i87.photobucket.com/albums/k146/tndonor/cylwall.jpg

[tndonor]

The head had no crack or hot spots, nor did the head gasket. Once the head was off, I put it in the head rotissarie my friend made to drop the valves, springs, etc. The head is getting o ringed to handle the extra boost.

Nest was to take off the timing cover and check and inspect the camshaft retaining bolts and killer dowel pin (kdp). The camshart retainer we fine. The KDP:eek:
http://i87.photobucket.com/albums/k146/tndonor/outkdp.jpg

The small dowel next to the bolt alignes to block and houing during assembly. These steel pins can walk out and drop in the geartrain causing the cam to break, ruin the injection pump, and all kinds of wonderful damage. Had I kept the motor in the Dodge much longer, I wouldnt have a motor. So I took a punch, drove it back in. You fix these by removing the bolt next to it, and placing a tab which is secured by the bolt and covers the hole. $3 part that can save $$$$$$$. This dowel was more than halfway out!
Back in

Currently the frame was sleeved for the front shackle reversal. The head is at the shop. I notched the ford D60 webbing for theU bolt. Need to find my camera charger. The camera stays charged so long, I dont remember the last time or place I charged it haha.

[Elliott]

You covered a lot of ground!

[The PIG Smith]

You guys with Cummins powered J Trucks are killing me!

Excellent project.

How do you compare the M-715 engine bay to the civilian engine bay?
They look very similar to me.
Are you planning to run an intercooler?
If so, do you think there will any space issue with 6BT and the intercooler in the engine bay.

Zach from ZMJeeps has a sweet setup with his 4BT powered J20, but his 4BT leaves rooms in the front of the engine for a fan.

Are you having Scott from Tennessee Diesel Conversions assist with this project?
I've spoken with him via PM over on the 4BTSwaps forum and seems to be a super nice fellow.

[tndonor]

Im not sure what it is about the engine bay in the M series versus the civy J trucks. I havent put a tape to both but it looks like the fender wells are wider and the firewall to front valance in a bit longer.

I will be intercooling..... a must with twin turbos lol. It will go in the front valance and Ill cut two holes in the back side for the cooler inlet and outlet to stick out of.

Yes Scott from TN Diesel is on it with me, or I should say Im with Scott. We are looking at some FSJ conversion parts, not sure how that will pan out. Scott is a great guy. Super knowledgable about these B series motors and conversions in general.

I wont be toping this build. One this is my dream build from 15 years ago. Two, not sure how you top a twind M715 on one tons with a bunch of expedition goodies

[tndonor]

You covered a lot of ground!

I does when I post updates haha. It always seems to move slower when its under the knife and not on the road. Guess thats how it goes.

[jeeperjoe]

that is going to be the sweetest of jaw droppers, looks like you just caught that dowel pin, those heavy p7100 pumps really like to come loose, and wiggle, your probably considering the studs to accomodate the oring, an upper stage fuel plate would be easy to install at this point, shove it all the way forward for max fuel, governor spring for longer fueling thru rpm band, the larger intake horn from a third gen really ups the breathing and spool up, im running cooler tubz, what a difference, with 3" pipes, theres a lot of compound setups on 1st gen d.t.r. alot of induction views, youve probably checked, keep this thread rockin! by far one of my favorites, good work!

The dowel pin is for the timing housing. The p7100 is heavy, but its not attached to the pin. The pin aligns the housing ot the block on the assembly line.

Another place that needs inspecting anytime one of the Cummin B series motors is out are the camshaft retaining bolts. If they ever walk, they usually break in two. Mine were good but a little locktite never hurts

[elij10travis]

wow this rig is freaking sweet how much all in all do you ahve invested into it looks like alot of money right now looks fun 2. that is over built but overbuilt means its harder to break and i like overbuilt. keep us updated what a sweet rig.

[jode]

Not sure how to subscribe without posting, so consider this post a compliment on what looks like it is sure to be a mighty fine vehicle.

[tndonor]

I actually figured up roughly the other night what I have into it and the parts I have that arent on yet. Lets just say I used to say its cheaper than therapy......than is no longer valid.

I wont say how much but most get the idea when you get a built Cummins and compound turbos, new trans, doubler, and built axles. Oddly enough, its the odd ball small parts that end up costing more or at least more than one would think

[FSJeeper]

TNdonor, I enjoyed watching your 4bt J truck build but this one is incredible. I'll be watching this buildup for sure.

I am doing a 6bt swap in my j10 got a mint frame axles and the motor is on the way (1st gen 6bt nv4500 241) I know you were talking about motor mounts being ripped off by some bigger companies I would be interested in buying some from your buddy if he is willing. Thanks! -Trevor

will do just got the motor today and have a bare frame stripped down ready to fab everything i will snap some photos and start a post just look under cummins 6bt conversion in a j10 I should have the photos up next week.

you really dont need the body lift. up where you are at the wouldnt run the mechanical fan. My electric fan doesnt come on ever during the winter, unless i'm towing up the mountains.

[Phillips889]

Ya i have heard they run cold but my motor is a non intercooled so I would like to leave space in case it heats up in the summer while towing my car trailer. Also I am running 37 inch hummer tires with the axle flip so I need the extra lift to clear them:D

Any updates?

[tndonor]

Ill have some pic updates later this week. Its been back to those 90+ hour weeks.

I got the front axle buttoned up (all seals and bearings). Put the new kingpins in. New lock outs are in and it is on rollers!!!!!

The frame has been sleeved for the shackle reversal.

On the list for this week is to drill and tap the doubler for the NV4500. Reseal the doubler and get ready for bending some tube for the trans, doubler and maybe cage. Cage may wait for a bit.

Head is at the machine shop getting oring. Ill be painting the motor. Words are teasers I know. Ill get some pics up.

Thanks for all the comments and those who are following (never thought this many people would be excited to see updates)

[AMC-J/20]

Why the C-14B/D60 combo ?

I figured a D70/D70 combo would more up to par with this build :eek:

I wanna see how this works out . . .



Mike

[tndonor]

I went for the 14 bolt for strength and aftermarket support. The 14B is stronger than a 60, locker is sheaper, cheaper to disc brake, etc. Plus I can go to the pull a part and for $20 buy shafts should I break them.

Most Dana 70 fronts were closed knuckle. I upgraded the 30 spline stub shafts to 35 spline stub (just like a 70). If I start going through front shafts, then it will be D60 cv axles.

Like anything, it is how you drive and treat it. If I drop the clutch at WOT on a rock, then yes, nothing will hold 1200 ft tq.

[mschillingii]

WOW! i just wish i knew as much as you! thats lovely. I really wants to drop a turbo diesel motor into my mud wagoneer. but i know as much about diesels as i do french lol!

[tndonor]

Picture time.

Front axle got new rotors, all new seals and bearings, and new kingpins. I also threw in rockcrusher drive flanges too. I didnt take picture of the installation if hubs seals, etc

http://i87.photobucket.com/albums/k146/tndonor/P8261093.jpg

After looking things over, a new steering gear box mount will be made. It will make mounting, servicing easier. Also will get a better steering shaft angle if it is adjusted.

[tndonor]

On the to do list for tomorrow is grind the plasma fun. Reseal the NP203 and reassemble the doubler. Drill the face of the doubler for the NV4500. Thats all the update I can muster right now....... Im 34 hours into a shift right now and no relief in sight.


Till next time

[tndonor]

Got the front suspension DONE!

Here are the frame hangers that have been on.

Once everything was burned in, the bolts were removed and the sleeves were then welded from the inside.

[tndonor]

In the second pic above, the shackles are in. Didnt think that installing two 9/16 bolts sneeded a write up haha.

[tndonor]

Got the winch CHEAP. Everything works and it was big enough I couldnt pass it up. Also got the intercooler fitted and mocked up. It wont be hard mounted until the motor is in as a new intake must be fabbed and the second turbo isnt in its final resting place. There is some adjustability with mounting it so until everything is ready, it makes no sense to possibly have to redo it later. Yes its a tease, nobody has really shown how to put a good intercooler in these trucks.

Also got a tilt column for the truck and intermediate steering shaft. On the near future to do list is remount the power steering gear box. Paint the motor. Assemble the motor. Start building the hotpipe for the compound turbos.

[AMC-J/20]

I had no idea the GM-14 was as strong or stronger then the D60 :eek:
so the rear end in my K2500 is very strong ?


Mike

[El_Diablo]

the 14 bolt is a good bit stronger than a dana 60

http://www.akfabshop.com/alaskaoffroad/images/Tech/14vs60Raxle.jpg

the 14 bolt is the larger

http://www.akfabshop.com/alaskaoffroad/images/Tech/14vs60Raxle_2.jpg

the pinion also has its own support and bearings making it much more stable and of course stronger, the fully floating axels are also nice since you can swap them out in no time with very simple tools without even having to jack up the vehicle

Thats the idea. What intercooler is that? Where are your inlet and outlet tanks positioned on that?

Ill be using a Ford 7.3 (all aluminum...not plastic end tanks). That coolers tanks are 34ish inches outside to outside. Frame rails are about 29 inside to inside. It was interesting.

There used to be more opposition from the purists about cutting anything. Guess they figure its better for someone to love it and make it their own than to be scrapped.

Oh yeah, nice willys sign in the background!

Just like THE PIG SMITH said that beautiful creation is Zack's handi-work on his Project Humpty. IIRC the intercooler is all aluminum, no plastic, with the tanks being on the sides with the inlet and outlet being on the top corners where you see the blue hoses. The intercooler Zack chose fits in the front of the radiator and IIRC he didnt have to cut the opening at all and only made some custom brackets to mount it. Its an ingenious use of an existing intercooler and the routing is great. I didnt like the other options I had seen for mounting and hadnt made up my mind fully to switch to the smokey side but it was one of the big helpers in pushing me over the edge. :thumbsup:

when you start to wheel big, its not if, its when ;)

[Tigger4X]

When I began to consider wheelin' BIG I sat back and did a bunch of research, asked even more questions, and kept digging. Then I thought BIGGER. Its not a guarantee, but I'm hoping by going bigger I can try to avoid some of the ugly stuff. :drivin:

[AMC-J/20]

I'm not a wheeler, well not in the way you guys do it . . . I do get in the soft muddy muck ? sure notice all my truck's have Mudder's, swamper's, Super Traction's, and Extra Grip's ;) Bisaply / Radial don't matter :cool:

:D If they ain't howling i'm getting stuck just that simple . . . I buy tires by noise, the loud they sing the less i get stuck :thumbsup:

When your in the mud your trial riding or some thing to that effect, when i'm in the mud i'm tow/Hauling 9,000 - 90,000LB's . . . Getting stuck just ain't an option :eek:

[jeepmj_tj]

Went for a drive in my GTO with a friend on US 129 "Tail of the Dragon" for a new addition

I've been on that road a few times. Last time it was by accident as it had been a few years since the last time I was there, didnt recognize where I was at. I was towing towing my jeep :banghead:. the cummins felt good but it was slow going. didnt piss too many people off.


what radiator are you running. in my swap i didnt have enough room to fit the intercooler behind the grille support with out the radiator being too close to the engine.

[tndonor]

For the radiator, Ill be using a Summit or Jegs generic that is about 27 inches long. The Cummins motors dont run hot. When I had the small 22 inch Summit radiator in my 4b, water temp was 160 while driving.

The radiator support will be cut back and centerd in the truck.

Anyone know why the M715 radiaotr support is not centered in the truck and why the passenger side fender is larger?

Anyone know why the M715 radiaotr support is not centered in the truck and why the passenger side fender is larger? My brother has a 4BT in a 1997 Ford F-150.
The truck originally came with a 4.6L V8 gasser.
The gasser radiator is way to large for the 4BT.
In the winter, he keeps a piece of cardboard over the front radiator to help get water temps up to provide some heat in the cab.

[jeepmj_tj]

I'm using the stock jeep radiator which has worked fine for 3 years, two of those i never even had a fan. the radiator is in stock location and the engine is within 3/4" of an inch away from the firewall. there is less than 3 inches between the radiator and the pulleys. I was able to offset a 16" low profile electric fan.

[tndonor]

I have 2 inches between the rear of the block and the firewall. Ill have 4 inched from tehelectric fan (taurus 2 speed) to the radiator. The fan will be on a toggle like my last one. I only had to turn it on when playing in the mud (high RPMs and little airflow). Also nice to turn the fan off in water crossings.

[Tigger4X]

...

You dont have enough room? Check out the intercooler pic I posted above. Zack did that amazing work on Project Humpty. You might be surprised by how it fits.

[jeepmj_tj]

the problem is he is running a 4 cyl lots of extra room. I dont know if the fire wall is different between a m715 and a j-truck to allow the engine to sit further back.

I am using the factory jeep radiator in the stock location and the engine is within 3 inches of the radiator and its less than 3/4" of from the fire wall.

I am using a dodge first gen intercooler that sits less tahn a inch in front of the radiator.

[Tigger4X]

I was under the impression that Zack's intercooler sits in front of the radiator so you dont have to worry about the space between the radiator and engine.



Did I miss something :confused:

[tndonor]

Intercoolers should always be infront of a radiator. If it sat behind the radiator, the airflow would be drastically reduced as well as heated up from the coolant temp.

[Tigger4X]

TNDONOR ... Common sense would indicate such, but for a minute there I kinda got fuzzy.





JEEPMJ_TJ's comment "the problem is he is running a 4 cyl lots of extra room. I dont know if the fire wall is different between a m715 and a j-truck to allow the engine to sit further back.

" about (edit) HIS engine and radiator placement was a bit confusing; considering that Zack's intercooler fits in front of the stock radiator.

[tndonor]

My intercooler is in front of the radiator. It has to fit where Zack put his. I had one in my J10 like this

[jeepmj_tj]

not sure where the confusing came from about intercoolers behind the radiator???????

I understand that Zack got his to fit as well as your old truck. but If i'm not mistaken were the radiators in the factory jeep position? The 4cyl cummins allows for alot more room for changing the locations of such items. I just trying to figure out whats different to be able to fit the larger 6 cyl engine and have both the radiator and intercooler behind the grille support with out having to cut it or modify the firewall to allow the engine to sit further back.

I was just comparing my truck and motor swap to see if something was different as in the shape of the firewall or radiator support as my truck there isnt that much room.

[Tigger4X]

I think he got confused with my babbling and thought I was talking about the cooler going behind the rad.

As for Zack's intercooler, yes, the radiator is in the stock position with the intercooler in front of it and behind the grill.

I forget exactly who it is, but when I find out I'll post a link, but there is a guy on here that has both a 3.9 and 5.9 Cummins who supposedly didnt have to cut the firewall. IIRC both of them were right up to the firewall and there was enough room. I'll try to get clarity from him and post up what I find out.

im using the dodger intercooler and it fits behind the final type waggy grille. it would probably also fit behind a razor, but i had to cut the grille support to fit it so i will not be able to ever run a Rhino grille if i ever stumble across one. thats what i was wondering as to an intercooler fitting between the stock radiator and the grille support. (not just the grille)

I guess their intercooler size is roughly the same dimensions as the radiator in order to fit. the dodge units are wider than the radiator supports. Thats why i had to cut into my grille support toward the faux vent holes. not sure the benefits of using a larger intercooler compare to the coolness factor of being able to run the rhino grille.

Sorry to hijack your build thread..

[Tigger4X]

Its been some time since I have been under the hood so I need to get out and see first hand what it takes to alter the opening. I hadn't made up my mind between a rzor and a rhino grill. It'll also depend on finding out what the final clearances are between a 3.9 and a 5.9 under the hood. We already know a rad and cooler will fit behind a razor with a 3.9. IIRC they could be moved back to accomodate a rhino with a 3.9, but I'd like to know what optins are there for the 5.9

[tndonor]

Wow, I really have a problem.......I just bought an Oasis air compressor:eek:

I was going to convert my sanden to a greasable zerk like the outback air and fab the rest. Not anymore. Maybe I should rename the truck Project Ecomony Stimulator.

Impacts...check
Air horns....check (as if they wont see or hear me comming)
Tire inflation....check (Ill likely be the filling station at trailheads once one person comes up).


Look for some OBW updates soon!!!!!

[tndonor]

Oops..... the Jeep military purists are really going to blacklist me.

Just bought a warn 12000 industrial (worm drive) for the rear. Looks like my truck is going to have more non original crossmembers than it did original hahaha:D

Well today was a good day. Motor started going back together. Head got thrown in the head rotissarie my friend built and the new 60lb valve springs. The 60 lb dprings are a must for turning the motor over 3000 rpms. They keep the valves and pistons from kissing one another.

[tndonor]

Next was changing the rack plug. This allows the internals of the pump more travel for more fuel over a wider range. This plug can only be accessed (without grinding the timing housing......dont know why some do that) is to take the pump off or loosen it enough to get the plug out.

[tndonor]

Next was to advance the timing. Stock timing was set at 12.5 gedrees BTDC, it was advanced to 17 degrees BTDC. This is done with a dial caliper in an adapter into thenumber 1 injection pump plunger, measuring the pump cam eccentric, measureing engine TDC, advnacing the pump timing, removing pump gear, rolling motor back to TDC and reinstalling gear. Whew
Not many pics as this wasnt a picture friendly part but here is proof at least I guess.

STOCK FIREWALL!!!!!!!!!!!!!!!!!!!!

The heat shield for the exhaust was removed. The brake amster was removed. Nothing has been cut or massaged on the firewall.

[CrewCab59]

Sure doesn't look like it , did you guys install the conversion firewall ?

[tndonor]

Yup. Ill sell M715 firewall conversions for the Cummins 6B. $200 shipped to your door. The shipment will weigh exactly what the package weighs. Can even fit it in an envelope for 44 cent shipping haha.

[Tigger4X]

Pretty cool the way some things just roll around, huh? :thumbsup: If one dropped on my foot I'd be screaming do it again!

Got the atmospheric turbo (larger turbo in a compound setup) figured out. Hotpipe material is 90 percent in, just waiting on a few odd pieces to get here and a custom hx35 backing plate and the exhaust can be run.
The exhaust is key as it will determine where the transfer case and transmission crossmembers can be run.

Here is the electric fans that will sit between the radiator and intercooler.

http://i87.photobucket.com/albums/k146/tndonor/fanspacing2.jpg

Here are the fans with the intercooler in its location. Plenty of room and hidden from sight. Should clean up the looks with no fans showing and no fan on the motor.

[tndonor]

From the underside, you can see that the intercooler, fans, radiator and motor all fit nicely. All without cutting the firewall to accomodate this!

With the front together checking for fit

Yes I painted eyelashes.....needed some levity at the moment

Look from above
http://i87.photobucket.com/albums/k146/tndonor/radiatorengine.jpg

[tndonor]

These are mock ups, just looking for routing options, but this is how it will be. Yes the welds and not smooth, they are not supposed to be. Again just mock up. Finished pieces are 90% done and will be switched out. There were lots of funn angles to get right and I didnt want to ruin my good stock with getting this right or having to redo this, etc

dude..........DUDE! That looks so amazing!


My dad is thinking about buying this beautiful 67: http://cgi.ebay.com/ebaymotors/1967-Kaiser-M715-Jeep-Military-5-4-ton-4-wheel-drive-/200568637952?pt=US_Cars_Trucks&hash=item2eb2d28a00#ht_1059wt_1167

Thanks,

That truck isnt far from me. Not sure what your Dad is going for but that is a great platform. Id be happy to store it for you:D I had two at one time and they were great stable mates. Mines getting lonely.

[tndonor]

Got the hydraulic assist in and figured out. Ram is a 1.5x8. The stock steering pump puts out 4.5 gpm, what a modified conventional unit roughly puts out. Going to use a remote resevoir that will increase the capacity another 3 quarts to help with cooling.
Steering bars are 1.5 inch .500 wall :D

http://i87.photobucket.com/albums/k146/tndonor/ram.jpg

[tndonor]

Started cleaning and painting the inside of the sheetmetal as it is about to go on for the last time. I put a rust preventative down before painting. Paint and body will be nowhere near the quality of my last rig. This truck is meant to be used and not so pretty Id worry about scratching it, etc.

Was cleaning sand and dirt from under the hood and found this
http://i87.photobucket.com/albums/k146/tndonor/army.jpg

Thought it was neat and cool so.............
http://i87.photobucket.com/albums/k146/tndonor/armypainted2.jpg

[tndonor]

And threw some beige on it to make sure it was the contrast was good. Yes there is overspray, etc.....just think of it like a sample.
http://i87.photobucket.com/albums/k146/tndonor/tanhood.jpg
Should have some really good updates soon!!!!!

[RussellS]

thats one sexy truck man your doing a very good job i wish i had the setup your blessed with lol

[tndonor]

Its getting time to put the front backl together!!!! There was a rusted fender mount that needed some attention. It was too far gone to support anything. So this is what happened
http://i87.photobucket.com/albums/k146/tndonor/P3081149.jpg
It will be rebuilt with 14ga sheet. Also gave me a good oppertunity to shoot some more rust preventative everywhere

[tndonor]

Went ahead and pulled the dash out tpo clean and paint everything. I shot the dash in Cummins Titanium black
http://i87.photobucket.com/albums/k146/tndonor/P3081150.jpg

[tndonor]

And started putting the tubes in for the final time. Reassembled with contant torque clamps. It was pretty exciting to be doing that for the last time. Here are some pics and a short walk around video for everyone who requested.

:D Looking good Nice job :thumbsup:

Mike

[jeepjerry]

Awesome!....:thumbsup:

[SnowShoe]

This is a crazy BAD build...VERY impressive...

Great work...like you...I can't wait to see final project and some performance reports...:cool:

[austinaubinoe]

Just wanted to say I would have done the same thing with that old military stenciling.

[Brizio]

Just wanted to say I would have done the same thing with that old military stenciling.

Agree!!! Great idea!:thumbsup:

[Dumpy]

This is gonna be one amazing truck!

[tndonor]

This is a crazy BAD build...VERY impressive...

Great work...like you...I can't wait to see final project and some performance reports...:cool:

If it doesnt put down 500 HP at the wheels......the motor has to come back down for a cam and bigger injection pump. Its a bet I have with a friend.

Ill have some video of the truck at sled pulls when the fairs and pulling events start up again :D Nothing like 65,000 pounds of resistance behind you to find the weak spots

[BDC1]

What hydroboost setup are you running? I see it in a few pictures but I didn't catch any info on it.

I suspect that will help with hydraulic clutch mc clearance issues? Chris

[tndonor]

I got the hydroboost and mounting plate from Elliott here on the board. This particular unit came from a chevy 4500 IIRC

[BDC1]

So I should contact Elliott for more info on this?

[cajun_lad]

Reading builds like these make me realize just how empty my pockets.

I think somebody already asked, and you may have already answered, but are those MRAP seats available online somewhere? Or did you just have a lucky find?

[jode]

Looks like it is just about "time" wish I could be there to hear this thing fire up for the first time. I absolutely love the sound of a built Cummins - the fact that it is in a FSJ is the icing on the cake.

[tndonor]

BDC- yeas, contact elliott with what you are needing, he'll help you out.

Cajun- I got the seats from someone who bought a bunch at auction. Last time I checked, he was out.

[BDC1]

I already posted on his HB thread. Thank you, and good luck with the build. Chris

[Leapfrog]

Sooooo jealous! Looks awesome.

[tndonor]

Time for a few updates....
Got the transmission and transfercases cradle figured out. This is the base of the structure. The hoop goes over the NV4500. It will have two 90 degree bends with break points that go the front of the hoop. The middle will have a plate to cathc the NV4500 mount. I have a smaller hoop for the rear which will catch the NP205. I know thats a lot to visualize but thats what it is.
Slight learning curve with a new tube bender haha.
http://i87.photobucket.com/albums/k146/tndonor/P4201176.jpg

[tndonor]

Finally got some time to get the new steering box on. Used some angle made from 1/4" steel and gussets on the backside to tie it all. Also cycled the steering to mark the mounts for the hydro assist. The bars are .375 wall. Heims are 7/8x3/4.
http://i87.photobucket.com/albums/k146/tndonor/P4201175.jpg
http://i87.photobucket.com/albums/k146/tndonor/P4201174.jpg
http://i87.photobucket.com/albums/k146/tndonor/P4201173.jpg

[tndonor]

Steering box.....not trimmed yet. Will be flush with the frame from the side and contoured on the bottome to match the box.
http://i87.photobucket.com/albums/k146/tndonor/P4201172.jpg
http://i87.photobucket.com/albums/k146/tndonor/P4201171.jpg

[tndonor]

Here is what the cradle will look like. I wont be able to get a picture fully together as the upper part will remain between the floor and trans when welded.

This is just sitting on its own weight so the angles and such are off. The rear hemi loop id what will catch the NP205. One side is lower to accomodate the clutch slave cyl.

http://i87.photobucket.com/albums/k146/tndonor/IMG00031-20110422-2039.jpg

[Chumley360]

This is a very, very nice, clean and impressive build. You have given me a little more confidence in trying to use just a plain 'ole non-IC Ram 6bt in my project. Keep up the awesome work!

[tndonor]

Well things have been slow for a bit. Between working and the recent passing of my father 2 weeks ago, Im just now getting back in the saddle. So here we go.
First order was to ge the cab off and finish some welding. Also made getting the triple stick linkages worked out ALOT easier. So off it came.
http://i87.photobucket.com/albums/k146/tndonor/P5111185.jpg
And got the fittings for the heater hose/ cab heater installed and welded in
http://i87.photobucket.com/albums/k146/tndonor/P5111184.jpg

[tndonor]

Some general pics of the drivetrain out in the open

http://i87.photobucket.com/albums/k146/tndonor/P5111181.jpg

[tndonor]

Here are the linkage bars for the 205. The 205 rails were modified so 2L and FWD are possible. The 203 linkage is about as easy as they come so I didnt take a pic ot it. The shifters will be maounted on tabs welded to the top halo bar
http://i87.photobucket.com/albums/k146/tndonor/P5111182.jpg

[tndonor]

Here is where the top halo mounts to the crossmembers. The front is a pad mount secured with bolts and the rear is a tube breaker set.
http://i87.photobucket.com/albums/k146/tndonor/P5111186.jpg
Here is a side view of the tube breaker
http://i87.photobucket.com/albums/k146/tndonor/P5111188.jpg

[tndonor]

For the next little bit:
Mount steering box and trim steerng box mount
Mount hydraulic ram and lines to box
Cut cab floor for shifters
paint tubing, trans, and xfer cases
Remount cab get steering shaft located
Bend roll cage and seat frames
Tie cage to frame
Mount seats
Start plumbing oil, water, fuel, electric, etc

[66Stepside]

This is one great project, keep plugging away at it!:thumbsup:

[tndonor]

Cradle is done. 1/4" skid plate is welded in. Tabs for the shifters are also welded in.

Wow I am looking forward to seeing the completion of this project.

[krek]

I don't know how I've missed this build before now.

AWESOME work!

I'm subscribed, keep it up! :cool:

[tndonor]

Cab went back on with mew body mounts.....fisgured what the heck while it was stripped down that far
http://i87.photobucket.com/albums/k146/tndonor/P5211207.jpg
I had bought a mojave heater for the truck sometime ago. I didnt like how I would have to have mounted it with the limited outlets and options it gave me. I ordered a unit made by Danhard. In addition to the four front outlets, the defrost outlets (2) are on top which is perfect. I picked up some NOS defrost ducts for the truck. This heater allows you to completey isolated the unit from the coolant so you the unit itself will not be hot when I dont want it to be......summer etc.

Currently the truck is getting the seat mounting and in cab configurations done. I have a panel from 12v guy ordered to include incab which controls front and rear, keyed ignition, 7 toggles with circuit breakers, and battery isolation monitoring/control.
All guages for the dash are ready to the interior when it goes together (speedo, oil, water, boost, pyro, volt)
Will be building a center console to house the electrics. Once this is a bit further, the cage will be bent and seats mounted.

[scorge30]

I am most impressed with this build.

I am subscribed as well and look forward to the updates.

[81jseries]

Awesome project.

Updates?

[budojeepr]

Awesome project.

Updates?
Yeah, what he said.

[tndonor]

I will have some updates soon. I cant catch a break it seems. After my father passed, I had a storm knock some 60-80 foot trees that crushed my car and ripped the power lines out of the hosue. 4 days after the storm, a tornado hit the house..... tree came through the bedroom wall while I was in bed. Missed my head by 19 inches.

Currently the rollcage is being finished. Main hoops are done, just taking the time to look at seat integration and console /wiring options. Havebought several goodies too Ill post up soon.

Wow, after all that has happended to you, I don't think anybody could blame you if you had to abandonon the project for a while. But you must be a true FSJ'er. Good luck with your house and I hope your family is doing ok.

I'll just stay tunned to see what goodies you have coming up.

[twisted frame]

Holy cow. Glad to hear you made it through. That's intense and a lot to take. It's nuts to think about how so much stuff goes on around us, all while going in and out of these builds that demand so much time and energy. Thanks for the update, and again, glad you're ok.

[tndonor]

Thanks for the kind words all. I havent abandoned the project....just had to take care of other more pressing issues. I have spend more time with a chainsaw than a welder recently. Progress is being made. My camera took a dump on me of Id have some updated pics. Ill probably get on this weekend.

[tndonor]

Update time. The roll cage is in (minus the head bars). Havent decided where I want to locate those yet. And its nice to still be able to stand up in the cab. Seat mounts are welded into the roll cage.

http://i87.photobucket.com/albums/k146/tndonor/IMG_0082.jpg

[tndonor]

I think I like the front panel black
http://i87.photobucket.com/albums/k146/tndonor/front1.jpg
Im also on the fence about running the rhino grill
http://i87.photobucket.com/albums/k146/tndonor/rhino.jpg
Also did an H4 conversion with Hellas They are just the 50/65 watt. Ill se how I like them. I might bump it to 50/100 later.
http://i87.photobucket.com/albums/k146/tndonor/hella.jpg

[tndonor]

Here is the plan for the rear winch. I got a great deal on a Ramsey RE12000.
http://i87.photobucket.com/albums/k146/tndonor/re12.jpg
It will go into a skid/mount under the bed. This is a piece of 1/4 plate put in a brake. The winch will go inside and be nice and protected.
http://i87.photobucket.com/albums/k146/tndonor/winchskid21.jpg
http://i87.photobucket.com/albums/k146/tndonor/winchskid22.jpg

[tndonor]

I had panel made for the batteries, winches, lights, fan, etc. 12v guy made it. Its the GLO panel, Ill get pics up. Its pretty slick. It will be mounted to the spreader bar on the cage.
The next little bit is getting the throttle cabel in, clutch rod in, PS hoses made and the wiring ran.
Ill post up when I get something new worthy

[Chumley360]

Looks great! It also reminds me that I need to start working on mine again. Hey watch out for those wiper motors, I bought some that look just like those the first time around and they lasted just long enough to get through an inspection.

[tndonor]

Bulk upload time again.
I had a panel made by 12voltguy. It has my ignition, front and rear winch controls, battery controls, and of course switches for lights, etc. I had it done with circuit breakers instead of fuses.

Next was time to address the rockers. Aside from being metallic swiss cheese and housing a rodent and babies, they needed some love. So they got cut out. Had two pieces of 1/4" plate sheared and formed the rocker from that. They are welded to the frame with DOM and tied into the cage supports going to the frame in the front to prevent peeling. They will also act as sliders and be able to support the weight of the vehicle.
The outside of the rockers were capped with 22ga sheet. 1/4" flat stock was welded into the V to provide internal resistance to collapsing

And under the battery box lid......
http://i87.photobucket.com/albums/k146/tndonor/IMG_0138.jpg
This is where the Oasis compressor will live. I have some more venting to do. It already has the hole in the bottom for the power cables and air line to exit the cab underneath.

[tndonor]

OX Locker cable is in and the location has been worked out.
Tomorrow is finish locating the steering wheel and mounting the floor plate seal/cover thingy around the column. Also mount the clutch master to the firewall.
I switched directions on the ps pump. I yanked the stock ps pump and put in a zf hydraulic pump. Went from 1 gpm to 4.5. Also went from metric ps box fittings to -6. Because of this I has to relocate the radiator up to accomodate the 90 degree fittings. All that is left is to make the ps hoses.
Hydroboost is mounted to the firewall ofor the final time. May get the hoses done tomorrow as well. Im not sure where I am going to put the ps cooler at. Space is becoming premium. I have an idea but wasnt the front bumper on before I commit to it.
Bought 5 gallons of gear oil to fill everything. Have 4.5 gallons of collant to put in. Ill stop there and hope I get this done this weekend.

[HD_JEEP]

SICK BUILD......:eek:

Thanks for keeping us up to date...:thumbsup:
