clutch problem revisited

[Alan Weeks]

I have gone "back in" for the redo and found that the clutch plate was installed correctly (springs toward transmission). I am assuming that the clutch fork was not properly seated against the throw out bearing. There is only one thing I can think of that is worse then a redo and thats a double redo so before I "close her back up" any last words of wisdom for me??
Thanks

A few things that I would offer:

1) Make sure that the clutch fork retainer (the u-shaped, spring steel piece riveted to the fork) end tabs are WITHIN the groove on the release bearing;

2) Make sure that the clutch release bearing is the proper one for your application. Among other things, it should be 1-1/4" long;

3) Make sure that the clutch and pressure plate that you are using (assuming that you replaced these components the last time in) are the correct ones for your application. This will be hard to check unless you have the box that the parts came in. Even then, if the box looked like "someone might have been in there before" (and, possibly, "switched things"), I'd want to ABSOLUTELY CONFIRM that you have the correct parts. You DEFINITELY don't want to go "back in" again;

4) Check the flywheel retaining bolts to be sure that they are the correct design and fully seated and torqued;

5) Carefully examine the clutch friction disc and pressure plate for signs of any problems which may have been caused during the initial operation. If there is any sign of damage or "interference", that may be another "clue" as to what the problem is.

Re: clutch problem revisited

Expanding on what Mr. Joe said about the clutch fork. It is possible to slide the lip of the throwout bearing between the end of the clutch fork and the riveted spring tabs. Actually it looks quite sensible that it could hold and retain the bearing. (I have to justify a previous mistake myself). However, the end of the fork and the spring tabs both must be seated within the groove and not straddling the lip. You will not get the clutch to work if the fork is seated improperly.
