Question Waggy on Rockwells...

I am thinking about putting my wagoneer on 2.5 ton rockwells, here's my question could I still use my dana 20 and mate that to a divorced np200?


Or would it be easier to mate a 203/205 to my T18 and trash the 20?

I am pretty sure you would have to change the output shaft on the T18 for the 203.... also you would have to drill some tap holes into the case or make an adapter.

I think you could still use your D20... question is why would you want to?

I'm just thinking of which case would be the cheapest, with keeping my tranny.
My overall goal is to try and use as little money as I can.

What tranfer case is strong enough to not worry about, besides an atlas, that will mate up to the T18?

it $175 for a standard GM 205? yikes, they are maybe $100 if they are painted pretty around here. i got mine with an SM465 trans and bellhousing in great shape for $200 all together.

you can twin stick a D20 too, 205 isn't the only one.

i have a FSJ model T-18, and D20, the D20 is cut down to just be a range box. (cut off the front output and plated over with 1/2 inch) and that runs to a divorced 205.

your plan would work fine, but you will probably want to either get a ford or CJ T-18 (ie without spacer between bellhousing and transmission case (or do an NP435 / SM465 swap) OR do something to get a liiiitle more wheelbase so you can have a decent length driveshaft.

now, rockwells will help a bunch with driveline angles, but IMHO i still want a longer shaft for the reduction in the change in angle over the distance of travel (if that makes any sense)

i have scored a full duece worth of rocks. but i will not swap them in until i can scare up a GM NV4500 (or i cave in and adapt a TH700)

peace
Dave


EDIT. also, so the information is out there... per a little experiment desert beast helped me out on via the interweb... you can slide a GM 32 spline NP205 right onto a GM 32-spline np208 (slip-yoke style) output shaft... soooooo.... cut down a NP208, make an adapter to bolt between the output housing, and the input of the 205.... and... say you use a SM465... 6.54x2.61x1.96x4.10's = 137 to 1... or with the rocks... 225 to 1.....

dont waist any time with your 20, the 200 or the 205.

20 wont last long
200 is too odd ball
205 is too big and heavy althogh witht the first gear of the T-18, the high ratio is not as big of a deal

I would build a 300. they are strong eith the addition of 32 spline oput puts. They are easly found just about any were. Ypu can twin stick it, 4:1 it, flip it, and double it. In my openion the best bang for the buck T-case out there.

Stock they can be had for $150-$300 but with the addition of 32 spline outputs and tera low kit you could easly have $1200+ in one. But yah got to pay to play.

I curently have $900 in mine without the 4:1. Thats not bad in my mind when you consider the price of an ATLAS or STAK. Heck I have twice that in my TJ 231's. (AA sye, 4:1, chevy 231 wide chain, box for rocks doubler)

The way I see it, you should alway drop your coin in the drive train first. It will give you a much happier wheeling experiance with components that work well and dont brake.

and for an outlay of cash in the hundreds (low hundreds) you could run that D20 (with NO adapters - on the trans you ALREADY have) thru a short driveshaft (100 bucks if you have it made....) to a 100 to 200 dollar divorced NP205 (or 200 if you had one laying around) and have a setup with a 4:1 bottom range, and 32 spline outputs out of the box.

yeah, he should definitely drop 1200 bucks building a D300.....

peace

I just love the 300's and dislike the 20's (personal preferance). Sorry for the bias post but you now have my two cents.

he wants to go cheap. $1200 is not cheap.

I say if you're easy on the skinny pedal you could get the D20 to work with an output upgrade.

I'm sorry but putting a wag on rocks will not be cheap. Half assing it will not necisarily make the build cheaper once on the trail. just because it is posible to put it on rocks for $2000 with some stuff you have laying around does not mean it's right.

Now for the cheap yes a 205 will hold up to any abuse you through at it. Yes there there is a huge aftermarket following for the 205. Yes it can be doubled, twin sticked, low-max'ed and divorced. So if you must its is a good cheap case

But dont go into a build of this stacher with the intent of skimping on your most important components.

P.S. who wants to go easy on the skiny pedal. With the wight of a rockwell equiped FSJ you will need momenom and tire speed to concor many obsticles. Perhaps Desert Beast can atest to this.

I definately would like to do a doubler rather than throw in some low gears and just have one case. I don't wanna have that large of a jump from high to low gear. So I am probably gonna have to drop some dough.

The best option I am looking into is Northwest Fabworks's planetary gear box($1500) and put an output kit on the dana 20( about $500) shiiite. That's 2 grand not including driveshafts, shifters, etc.

On the other hand once I add the rocks my crawl ratio will be about 200:1!!!

im definately with dave on this one. you can use a ford 205 if you could live with a driver drop front. that would eliminate having to cut and plate the d20 for front drivesahft clearance(tho i myself had been contemplating that,a really slick idea )

stock 300 tailsahft is not much different than stock 20 tailahft,so save those arguments. the d300 is still basically a half ton,light duty transfer case that must be BUILT in order to be compareable to stronger cases.

the d20 is allready there,and 205s are cheap and bulletproof. any gear reduction that you add behind the d20 is going to help the tailshaft live,so no real need to upgrade the tailsahft until breakage becomes a big issue,IMO.

i beat on my d20s pretty hard and ive only broken 1 tailsahft in the last several years(knocking on wodden desk ). it even holds up well in my scout ii,wich runs really crappy gears( a close t19,4.10s in the axle) and a very torquey 345 that spinning the 38" hawgs.

the d20 is not bulletproof,but they arent so bad as mr welcht claims them to be,either.

now ya have my 2 cents as well

I wouldn't add a reduction box to a dana 20... if your gunna spend dough, go with a 203/205 doubler which will be cheaper.. and your thinking about spending 2000 g's on a d20 set up just buy a atlas or stak.. but thats just my opinion

not adding a reduction box to a D20. turning the existing D20 into a reduction box. no longer a transfer case. no front output. keeps original trans, no adapters, just a short driveshaft to a nearly bulletproof NP205.

peace
