dual transfercases????

[never_2_high]

i have a jeep waggy 85 that is what i wound consider all wheel drive but it is full time foure wheel drive the quadratec and i want to run two t case i have a decorced np 205 that i want to put be hind it and my question can it be done and is there any where i can read up on it .... is it a wise idea to do something like this

[Dmntxn77]

I dunno for sure, but I dont see how you could do it with a full time case, since you dont have control of the case.

[shackwrrr]

you would have to put the part time case before the full time case. because the full time case befre the part time would make it not work. the reason is that your front case just acts as a low range unit and your rear case runs the axles. if your only hook one driveshaft to a full time you will not move and ruin the xfer case. if you mount the part time case first it will act as a low/high gear box on top of the full time case so the truck would act the same you would just have a extra selection of more low range. hope this helps

You won't have enough wheel base to run a divorced 205 behind anything in a wagy, It was borderline in my J10 :rolleyes:

[never_2_high]

my whole objective is to gain part time 4 wheel drive so i guess i need to find a tail section from a two wheel drive 727 trans and run just the np205 i hat my waggy being fulltime four wheel drive its just not effective four what i want

um,yeah,thats a great idea if you like doing things the hard way :eek: rebuild the trans,fab cross members to hold the 205,fab new driveshafts,shifters and linkage,not to mention it will want to occupy the same approximate space as your plastic gas tank.

in 85 you have a NP 229 transfer case(wich DOES have a 2wd),unless someone has done some creative parts swapping. even if someone has swapped in an 80-81 "quadra trac"(NP 219) a part time,no viscuos coupling,swap is easily accomplished by removing the case you have and bolting in its place a jeep NP 208.

seek a donor 80+ auto cherokee or grand wagoneer and get the transfer case,rear driveshaft,and the linkage that hooks to the cheesy plastic flag shifter. bolt it all in and all thats left is to block off the lines going to the now non-functional 2wd/4wd switch on the dash.

it is for this reason that i hate the common names that the dealer has given the cases-command trac,quadra trac,etc. crawl under your truck and look for a round ID tag in the middle of the case on the rear. it should read NP 219,NP 229,or something of that nature.it will also give the low range,and some other info.

we can better help you when we know what you have. further questions? :drivin:

Wow, just wow :banghead:

[joe]

Just to clarify here...is your 85 Waggy really an 85 Wagoneer or an 85 Grand Wagoneer? If it's an 85 Wagoneer it'll be the fancy 4 headlight version of the little XJ Cherokee(101" wheelbase) and not a FSJ (109" wheelbase) so there is no way to get a divorced 205 under it along with another tcase. As mentioned above if it's a FSJ 85 Grand Wagoneer it'll have the 229 Selectrac tcase and already has a 2WD mode.

[never_2_high]

ok i don't have a 2wd mode all i have is a floor shifter next to the driver seat and it has a high and a low andd thats it but why cant i just run two t cases i don't get whatr you are all getting at

Ok let's assume you have a FSJ 85 Grand Wagoneer here and not a smaller 85 Wagoneer(totally different vehicle and not covered by this forum). You then have the NP229 Selectrac tcase w/2WD mode). The lever you're looking at is just as you noticed for H/L ranges. It's mechanical lever. The vacuum operated switch that switches between 2WD and 4WD is mounted on the dash. It's just a small switch not a big lever like a floor mount shifter. You won't be able to switch the H/L lever into low range until the tcase is in 4WD again controlled by the vacuum switch "on the dash".

edit: only scenarios I see here are A/ you haven't found the dash switch yet. B/ previous owner removed it for some reason. C/ your tcase has been swapped to a part-time 208(also has 2WD mode) and just used your old H/L range floor lever for the 2WD/4WD/4WD low/Nuetral modes because now the dash switch isn't needed or D/ you have an 85 XJ little Wag and I have no idea what those used for running gear/tcases.

and there you have it :) good call,joe. i can see one other scenario. maybe he has a 75,not an 85,and has a real borg-warner quadra trac. this would be fairly eveident by looking under it,as the front diff would be on the passenger side. ;)

it is possible that someone swapped the entire drivetrain from an earlier truck into an 85,but not likely. it is quite possible that someone has swapped in the 80-81 "quadratrac"(np 219) in wich case the 2wd/4wd switch would not be needed. the flag shifter will control the modes(full time 4x,locked 4x,neutral,locked 4lo)

bottom line is that you need to crawl under your truck and look for the round tag on the back of the t case,assuming it is an 85,and that the front diff still is on the driver side.

why cant i just run two t cases i don't get whatr you are all getting at

if the full time case in question has locked high/low range options(np 219 or bw QT) then you *could* prolly run a 2nd t case behind it. you cannot run a 2nd case behind an unlocked full time case(228/229,or a QT not in E drive) because you wont be using the front output on the first case,and in a full time unit,all the power will simply spin out the not-connected-to-anything front. you have to have locked modes in order to make the rear output spin and spin the input on the 2nd case.

the other prollem that you have is that when you add the length of a small connecting shaft,and a whole nother case behind a 2 case,your rear driveshaft becomes that much shorter. 108 inches is prolly enuff to do it,but the shaft going from the rear case to the axle will be very short.

not to mention that the 2nd case will be in the same spot as your factory gas tank,so youll need to relocate the tank somewhere else. lots of guys use a bronco or xj tank mounted behind the rear axle.

and once youve figure all that out,you now have to get you frotn driveshaft around the first t case to the front axle. i assume that youre wanting to use a ford divorced case and keep your driver side front axle. youll have to modiffy case number one,or clock it up out of the way,wich will mean floor mods. typically dual cases use a driver front output case behid a passenger front output case,or vice versa. the easiest way to do a dual case system in an 85 would be to swap case #1 for a dana 300,and run the ford 205 behind that. you could run a dodge divorced case(passenger front output) behind a driver output NP case(jeep 208),but it will also mean a front axle swap.

at any rate,its alot of work just "to get part time". :eek: once again,the jeep 208 is a simple bolt int swap that you could do in an afternoon. but like joe said,you may allready have that if your 2wd/4wd switch is missing,you just need to check it out.

you are not allowed to ask anymore questions until you have at least crawled under your truck and looked for the ID tag. once again,it will be on the rear of the case,parallel to the front output. we can much better help you when we know for sure what you have. :thumbsup:

[never_2_high]

thanks guys i willl do that

[joe]

You could post the VIN here and we'll be able to tell what tcase it came with from the factory. Or look at your VIN at the 5th digit. "A" would be the NP229 tcase with 2WD Hi/4WD Hi/4WD Lo/Neutral modes. If it's "E" it'll be the NP208 part-time case with the same selections. All 85 GW's have a 2WD mode regardless of tcase but a 208 is rare from the factory in an 85. Those are mostly found in fleet rigs.

[never_2_high]

ok pulled the numbers off the tag it is a 208- am ser numbers is 12 11 79 so if it is a 208 how do i switch it between 2wd and 4 hi and 4lo?

[J10-401]

Still not sure what vehicle he has. VIN please. And do you have the Selectrac vacuum control box under the dash to the right of the steering wheel or not?

[never_2_high]

ok i have an 85 jeep grand wagoneer the dash switch has been removerd and the t case id tag reads this 208- am 536 1528 12 11 79 261 and the tag says new process gear

[never_2_high]

Still not sure what vehicle he has. VIN please. And do you have the Selectrac vacuum control box under the dash to the right of the steering wheel or not? the vin will do you no good because when you run the vin it says it is equiped with a th400 trans and it for sure has a 727 in it i know that for sure because i just had it rebuilt

[J10Mike]

If it is indeed a NP208, you already have a part time case. The shift pattern is 2H - 4H - N - 4L. The flag shifter will be all the way forward (or down) for 2WD. As you pull up on it for 4H, N, and 4L, you will feel the shifter sort of click into position.
Do you have locking hubs up front?

[joe]

the vin will do you no good because when you run the vin it says it is equiped with a th400 trans and it for sure has a 727 in it i know that for sure because i just had it rebuilt
Actually the VIN does tell you what tcase it came with Note: full-time = NP229, part-time = NP208 those were the only two possibilities for tcases in 85.

Regarding the 5th digit of the VIN from the factory parts manual:
A- 3-Speed Auto Column Shift-Full Time
E- Auto-Column Shift-Part Time/4WD

Anyway it's a moot point now since you've read the tag on the tcase. Apparently someone has swapped in a 208 in place of the 229 hence the H/L lever by the seat.
Just using the old H/L lever for a shifter is common on these swaps because the 208's that came stock behind auto trannies also used a similar flag style shifter but it would of had the complete shift pattern stamped on it. For your present application the floor lever now controls this pattern:
Bottom to top....2H-4H-N-4L. That of course is assuming who ever did the swap got the linkage hooked up correctly. :)

[never_2_high]

thanks for all the help guy i really do thank you

[joe]

No problem. That's what this place is for. With a bit of effort on your part and some on this end most issues get worked out. This place is sorta like the sign over the urinal in the restroom of a Chinese restaurant. "We aim to please. You aim too please." ;)

[A4x4luvinredneck]

I used to have a 85 grand wagoneer, auto trans and an np208 t case.Has the vacumm switch to the right of the steering column and the shirt shirter to the driver side of the transmition hump. It came stock like that and im 99% sure of that. I didnt even think they had another t case from the GW past 83? just wondering:confused:

NP208 did not use Vac to shift, so if it was an NP208 and you had the vac switch on the dash then it was not stock. NP229 would be the likely T-Case in an 85 GW. Did you have manual locking front hubs?

[never_2_high]

yes i do hav man hubs the vac switch was removed and a 208 was swapped in thanks again for all the help
