Reinstalling A Transfer Case

I dunno if you are still looking but I have a couple adapters I'd be willing to part with. Ill sell you one for 40 bucks plus a flat rate box for the ride. I was able to lift my 203 with the jock until the input. Then dropped the jack and lifted/wiggled it the rest of the way by hand. Use a couple ratchet straps to hold it onto the jack.

Used to bench press them back in the day. To old for that now and these days, I'd like to think smarter.

Hoisted from the rollcage is my preferred method now.

benched several myself, not anymore. I never thought about using the cage :doah::doah::doah:, I have used a cherry picker in the side of the cab.
 
I've searched and can't find a thread that shows step by step on removing a th350 and NP203.
If there is one could somebody show the link and also what's the best manual on these transfer cases and transmissions?

Thanks

Honestly it's probably just too straightforward to bother with. I think my Haynes and Chiltons both have a step-by-step thing on it, but I've only ever referenced them for torque specs and the 203 shifter adjustment.

I find with the COG of the 203, it's usually easier to just remove the tranny and tcase together with the crossmember if you have a jack. If you don't have a jack, I have been able to unbolt the chaincase from the gear reduction box on the 203 in the truck (this is really dependent on the floorboards, I don't see how you could do it on a Sub but it's easy in a K5).

If you just want to remove the whole 203, the tranny adapter has like 8 bolts or something roughly in a bean shape. They're all relatively easy to get to, but if you have a removable tranny tunnel, it will make your life a whole bunch easier. There are two of the mounting bolts holding on the shifter BTW.

The bellhousing on the tranny is a whole lot easier if you have that removable floor panel too. For the top two bolts on the bellhousing, you pretty much have to lower the back of the tranny down a few inches due to firewall clearance. Be careful though, it tips the motor backward too and you can damage your distributor. Also note that with the tranny mount gone, the motor will probably need to be supported to prevent it from tipping backward in to the firewall. You can just put a jackstand with a board under the back of the oil pan, but then it's in your way. I prefer to tie a rope or something to the lifting plate or a bracket on the front/top of the engine and strap it to the core support, front bumper, wall, etc.

A set of long extensions are pretty much awesome for doing bellhousing bolts. You don't need them, but they're totally worth it and come in pretty handy. http://www.summitracing.com/parts/TTN-12079/

If you're asking for a manual for the th350, this book is worth it's weight in gold. I'm pretty sure everyone that works on them owns a copy. http://www.summitracing.com/parts/HPB-HP511/ Honestly I would pay $50 for it if that's what it cost, it's totally worth it.

I don't know of any manuals for the 203, but there's plenty of exploded diagrams on the web. The thing is incredibly simple and all you really need is some Assemblee Goo and a 9/16" wrench to rebuild it. Oh, and sockets for the yokes. th350 thrust washers and shims seem to work well enough for adjusting endplay on the output shaft if you want to get that involved with it. I think spec is like .008"-.012", but if you just get it snug but still smooth and rotating freely it will be just fine.

Thanks! This is the kind of stuff I am looking for....it's the "color commentary" that the manuals don't give you...the "experience" of having actually done this...
 
Just thought Id throw in my 2 cents. I had the trans jack linked above.....operative word being HAD. Friend of mine borrowed it and tried to install a 465/205.......yeh.....carnage ensued, about crushed his skull and the trans/t-case was still strapped to it, laying upside down, next to the base of the 'accordion'. It folder over sideways. Anyway, I thought it a good excuse to upgrade, now I use http://www.harborfreight.com/800-lb-capacity-transmission-jack-3185.html. IMHO, much better setup and its only $50 more.

Yep...that looks a lot more stable and has the capacity to handle the th350 and np203 as a unit
 
the best thing i have used is a office chair with the back taken off.haha.put to bottom most setting and put transfer case or trans on it.then lift the adjuster and lift up the chair till it is high enough to bolt in.best trans jack ive ever used.

That would have been a chair from back when they made a good chair....

it was in the 90s,haha.the chair was a decent one but it was ripped and its all i could think of besides bench pressing the big 205 back up like i did the first time.didnt have a jack big enough or money to buy one,but needed a new clutch bad.it had enough spring it almost lifted the trans when i hit the adjuster.i thought that was the best part.lol
 
This is how I modified a transmission add-on for a floor jack. It allows you to tilt it as neccessary which really helps.
