mvusse Posted June 11, 2011 Posted June 11, 2011 I know someone here runs an AX15 behind a 4 cylinder using the Dakota bell housing. I would like to do that, but have a few questions: What clutch to use? Anything need done to the flywheel? How about pilot bearing?
mnkyboy Posted June 11, 2011 Posted June 11, 2011 82 2.5l comaro clutch disk,I have the part # somewhere For the pilot bearing I was gonna turn one out on the lathe but I've heard AA sells one that will work.
mvusse Posted June 11, 2011 Author Posted June 11, 2011 AX15 pressure plate and throw out bearing, or Camaro also?
Eagle Posted June 11, 2011 Posted June 11, 2011 AX15 pressure plate and throw out bearing, or Camaro also? If you mean the pressure plate for an AX-15 and a 4.0L engine, I think the pressure plate will be too big to fit in the smaller 2.5L bell housing. Dumb question: Since the bell housing to make this work is from a Dakota that mates the AX-15 to the 2.5L engine -- why not use the Dakota clutch that goes with that engine and tranny combination?

I didn't know if a Dakota 2.5l clutch would work on an AMC 2.5l engine, that's why I was asking. And I meant the pressure plate from the Dakota the tranny would be off of. My AX-4 does not have a 4th gear synchro, and it sounds like some bearings are falling apart inside (came out of a well abused 92 YJ). If I'm going to replace it, I figured I might as well upgrade.
mnkyboy Posted June 12, 2011 Posted June 12, 2011 From what I've read the 2.5l Dakota used a 14 spline clutch and ours is a 10 spline but I can't confirm that. The clutch disk is 9-1/8" OD and 1-1/8"X10 spline Napa #RCF4198 its for a 2.5l 4spd comaro The pressure plate and throw out will be 2.5L jeep stuff unless you went to the Dakota flywheel then you can use the 2.5l dakota stuff,I've also heard this eliminates the custom pilot bearing. I haven't done this swap so this is just things I've read as I've looked into converting mine over so don't just take my word for it.
mvusse Posted June 12, 2011 Author Posted June 12, 2011 Isn't the flywheel on our 2.5s externally balanced (or engine externally balanced at the flywheel and harmonic damper for the nit picks)? Can't be swapped out.
mnkyboy Posted June 12, 2011 Posted June 12, 2011 Not sure, but I found some people running the Dakota flywheel on 2.5l TJs. they didn't say anything about needing to balance them.
mvusse Posted June 12, 2011 Author Posted June 12, 2011 By the time the TJ came along, the 2.5s were internally balanced. My 1987 is externally balanced.
mnkyboy Posted June 12, 2011 Posted June 12, 2011 That would explain why people are getting pilot bushings made to use their stuff rather then switch to the Dakota stuff. What year did the 2.5l change?
