Rebuilding transfer case?

[rsm688]

How difficult is it to rebuild an H3 transfer case? I'm very mechanically inclined and have been working on cars and bikes for years, I've just never done any internal motor/tranny/t-case work before on a car (worked on bikes).

Are there any special tools required to do a rebuild? I know I will need the metal shift fork, what other parts should be replaced while having it open (other than the obvious of any parts that are damaged)


My t-case is bad, I am pretty sure the shift fork broke and the previous owner drove around on it for a while like that. He said you can drive 30-40 yards then it quits turning the tires. I've backed it up into my driveway on and off a trailer with no problems but don't wanna go drive around to test it out and risk damaging anything further.




Thanks,
Spencer

they come apart almost exactly like every domestic transfer case ever built. If you can do a motor, a transfer case is a walk in the park.

to your other question

You need to inspect everything carefully - and the first sign of major trouble will be whether or not the magnet looks hairy... if the plastic fork broke, it probably didn't do anything to it - though that "it only moves 40'" really has me wondering what else is wrong... as for what else to replace, the only other thing in the transfer case that can go bad (and still have a rebuildable case) is the chain.... but even then, it's pretty stout.

I did some work on a np 208 case once. Pretty easy I would look for slop in the bearings and check the chain look for signs if it slapping the case and that shift fork like you said. I had a shop do mine not too long ago when mine was acting funny and it was that plastic shift fork. Wish I had the time and the garage to play with it myself. If you do I would pull it and give her hell. If you run into trouble toss it in the trunk and take it in to the pros.

Thanks guys, I think I am going to attempt the rebuild myself. I'm gonna go ahead and order the shift fork and then tear down the case and inspect everything else to see if that is my only issue or if there is any other damage
