Clutch Problem

I have a 1974 CJ5 with a T14/Model 20 set up with a 258. The other day I got in my Jeep and immediatley noticed the clutch play wasnt right and the clutch grabbed as soon as I released the pedal from the floor. I re adjusted the linkage and everything seemed fine. I was perplexed that all of the sudden my clutch did that. Then after driving around for a while I started having a low frequency vibe in idle and while driving. Today when I got in my Jeep I noticed chattering as soon as the clutch was starting to engage. It engages fine and shifts fine and my low frequency vide has disaapeared but the chattering is consistant. When the clutch is depressed all the way in it goes away and when I let up it starts again. When the clutch is all the way out there is no chattereing. Any ideas as to what could be wrong?

Thanks Jim

How many miles on your clutch now? When you were down there adjusting your linkage, did you notice any wear? Get a flashlight and check it carefully. If your linkage is ok, chances are the pressure plate has taken a dump. My jeep had a lot of clutch chatter when starting from a stop. It got worse the warmer it got. I replaced the clutch, pressure plate, t/o bearing and pilot bushing all for about $145. Another $35 to get the flywheel re-surfaced and it's like new now. Good luck.

Or, you could pay someone to do it for you for an average of $400.

Just a guess but the rattling could be a throwout bearing or even possibly the clutch fork or the pivot is messed up. No matter if it's the pressure plate, bearing, or fork, it all means the same thing. Ya gotta pull it apart and check it out.

if your clutch is old and getting warn out it could be rivits starting to com e through and its not grabing completely but ill say it too PULL IT APART!!! better to take it apart and find out its a bering than to let it go and have to buy a new flywheel

I just finished replacing the clutch assembly. It was the throw out bearing and a bad transmission mount. While I had it apart I replaced the oil pan gasket, the seals in the transfer case, had the flywheel turned, and spent most of the afternoon cleaning the grease and grime from the components. Missed all the football games this weekend but I got all the work done for about $220.00.

Thanks for all the replies.

Man you work fast

You must have worked all weekend to get this done in such short order. I did the same thing you did but piece meal. I did my oil pan and rear main and took 2 days (not consecutive). I did the clutch but took several days (again, not consecutive). I bought a seal kit for both the transmission and the xfer case and took each one of those to a friend to install. Then I took extra time to find the new tranny stabilizer stud and washers and correct way to install it. It took the machinist two days to resurface the flywheel. So, all in all, my jeep was apart for better than 2 weeks when I did the same project. I guess part of my explaination is that I have a bad disc in my back and have to be careful.

Congrats on getting it going so fast.
