Quote from: LukeMacPU on November 06, 2025, 08:56:18 AMAny other parts work?  Finding some Jeep actuators, but would need to slot/drill the shaft to make it work maybe.  Any rebuild kits available for the vacuum motors?  Will be pulling ours to investigate next.

The Full size jeeps that used the NP229 transfer case used the same vacuum motor. They is a new after market version available. They are expensive but cheaper than NOS.

Sorry to bother again, but no parts stores have a .840 inch long bolt. Only 1 inch. Would that be ok or would it screw everything up?

Bolt measurements are always just the under-the-head length; at least they're supposed to be!

Flywheel bolts are J3170524; which the parts book says are 1/2 x 20 thread; 0.840 long (not including the head), steel, and are Grade 8 with oxide coating.

Alright. What about the flywheel bolts? Google says ½-20×1 inch, but is that overall length or under head length? I read somewhere that someone pulled .750 UHL bolts out of the flywheel

The Jeep / MOPAR part number is 53004596.  They occasionally show up on Ebay.  Good luck with the hunt.

Installing new coil springs / shocks up front, and coil over shocks on rear this week.  Also did some digging and found our transfer case vacuum motor is locked up (does have switched vacuum getting to it) which is why 4wd doesn't function.  Can manually switch to 4wd at the transfer case.  Any promising leads on new/used/rebuilt vacuum motors?  Any other parts work?  Finding some Jeep actuators, but would need to slot/drill the shaft to make it work maybe.  Any rebuild kits available for the vacuum motors?  Will be pulling ours to investigate next.

According to the parts book, its J4004165.  The AMC standard parts manual says those are 3/8 x 16 thread; 0.810 long (not including the head), steel, and are Grade 8 with phosphate coating.

 :eagle: What specs do I need for the pressure plate bolts for the 4.2 inline-6? I'm currently swapping the auto trans for a manual t4 and I've got everything but these. Google keeps giving me different answers, but I trust you all know what they are.
