I pulled the tranny the other day. Today I removed the clutch pressure plate, the friction plate, the pilot bearing, and the flywheel.
• The disc that holds the pilot bearing simply fell out of the end of the crank!
• The flywheel is a bit wavy in cross section. It needs machining or replacement.
Now the questions:
Can you reuse 4.0L flywheel bolts or do they need to be replaced?
If they *can* be reused, do they have to go back into the same holes in the crank, through the same flywheel holes? (In case this was true, I used a scribe to mark the flywheel, and I marked the bolts with a Sharpie and replaced them in the correct holes as soon as the flywheel came off.)
If I get a new flywheel is the LuK one as good as their clutch kit? (The price is right. The "Many Morons of eBay" seem to think that $468 for a Mopar flywheel is some hot deal. WTF?)
To remove the aluminum clutch housing spacer (the so-called "inspection plate") the flywheel had to come off as the guide pins stuck out far too much to allow the plate to bend enough to pop off. So the flywheel genie is now out of the bottle; I now have to re-install the flywheel when all this other work is done.
To the best of my knowledge there are no shops around here that can properly machine a flywheel like the ones we use (with a slightly domed surface). All the local shops that do this use a brake rotor mill which will make the face perfectly flat, which I have read repeatedly is not good for the TJ flywheel. So I am getting a new one. New bolts, too, I assume? The bolts are anywhere from $14 to $18 EACH! Is there a good aftermarket solution for the flywheel bolts?
Also, RockAuto lists a flywheel shim for the 2003 4.0L/NV3550 but mine does not have one. What is up with that? Do I need it? Does it go between the crank and the flywheel or the flywheel and the clutch?
I don't mind doing the clutch at all, but the flywheel was something I did not want (or expect to have) to remove. I am concerned about the pilot bearing/disc simply falling out onto the quilt when the clutch dropped off. I actually expected to have to do battle with that thing to get it out.
Any help here?
Thanks!
