Re: 97 TJ 4.0L Clutch Won't Release - Throw Out Bearing Gone?
Well I have part of the job completed and the verdict is a broken clutch
fork. Seems it folded up under the pressure. Once I get the old pressure
plate off I'll be able to tell if there was some sort of damage to the
pressure plate to cause the failure.

Do you think you have an aftermarket high performance pressure
plate in it, that would require something stronger?

All factory, had my jeep since new. I'll post a pick of the fork in the

Re: 97 TJ 4.0L Clutch Won't Release - Throw Out Bearing Gone?
I've attached links to some photos of the bad fork from my TJ. The throw
out bearing was still loose and smooth and turned with ease. However, it
was really jammed into the fork. Clutch and pressure plate were fine with
lots of life remaining. I replaced it all with Napa clutch kit (about $200)
and a new flywheel exchange. Flushed out the tranny and transfer case and
all back together now.
I will say the new Napa pressure plate has a shorter engage than the factory
(hope this doesn't mean it will slip or fail on the side of Mt. Rainier!).
Lets say the clutch peddle full travel in total is 1 -10 with 10 being
completely on the floor and 9 being where the clutch ignition switch kicks
in. The factory clutch disengaged at around 7 and completely engages around
2. Now the clutch is disengage at around 4 and engages around 2 as before.
A very short motion.
When I first backed it up I pushed the clutch peddle to the floor and kept
letting the clutch out further and further and further and I about gave up
on it. For a second I thought oh crap what the heck is this! Then it
grabbed and took off fine. I'll probably bleed the slave cylinder one more
time to make sure there is no more air in the line.
The first photo below shows the bearing spun down into the fork out 45° from
where it should be. Clips probably rusted and gave out.
http://home.earthlink.net/~retrojeep...tj%20fork1.jpg
Can see the transmission side of the fork. You can see the slots where the
clips should be. Also, the fork is wedged open. I put a straight edge on
the side and it was really stretched open.
http://home.earthlink.net/~retrojeep...tj%20fork2.jpg
This is the clutch side of the fork right under the slave cylinder end.
Because the fork was fully engaged the fly wheel ground into it.
http://home.earthlink.net/~retrojeep...tj%20fork3.jpg
Another view of the carnage.
