AX15 to NV3550 swap Qs

My AX15 is just about done. I located a NV3550 freshly rebuilt at a good price. I understand its just about a direct bolt on/swap. Couple Questions tho. Can i re-use my clutch, pressure plate, pilot bearing and Throw out bearing from the AX 15? I just put in a new kit about 1200 miles ago. Also, can i re-use my AX15 shifter? Can I also re-use my np231j? (I'm 99% sure that I can but want to make sure). Thanks.

Yes to clutch/PP/TO bearing. Likely your pilot will be fine as well, so long as you have the 0.750" input snout on your AX15 and that matches your NV3550 (it should). Unlikely you will need to remove your clutch assembly, and you should be able to just yank out your AX 15 and directly bolt in the NV3550.

I don't know about your shifter, at all. I do know there are 2 versions to the 3550 shifter, but they both go on the same shifter stub.

The bellhousing for the AX15 will directly bolt to the NV3550. Take a few moments to express thanks that you have the external slave so you don't have to mess with that at all. Yes, it would still bolt up even if you had a pre-94 version internal slave.

Yes, your NP231 bolts to the NV3550. As I seem to recall back in the wastelands of my cortex there may be an issue in bolting up the T case shifter though. Someone sober will need to post up a solution to that issue.


Are you SURE your AX15 is fixing to take a dirtnap? http://www.jeepforum.com/forum/f12/a...stion-1418288/

....I'm not smart, but I can lift heavy things.......

Yes, I'm positive. After going over the Jeep extensively today with a buddy of mine, listening to all sounds and testing everything out, it all came down to the transmission. I realized that I dont only get bearing noises in 5th. 5th was just louder than other gears.
As for the T-case shifter, I do have to get an adapter. Cost about $40. That's fine.
