Need advice. Replaced throw out bearing with a new one from Max Merrit. Adjusted the pressure plate forks, installed a new spring, used orgional housing, bearing pressed on to the housing by a machine shop, lubed and reinstalled.
Now there is a constant noise like the bearing is off kilter.
First mile or two everything is fine then slowly the noise returns when the clutch is depressed and then becomes constant.
Car shifts like a dream, clutch is smooth and there are no vibration issues.
What did we miss?
Advice appreciated.
thank You

Can't say I've ever head a throwout bearing noise called a rattle, more like a whine, but if it's constant even when the clutch pedal is relaxed it's usually because the pedal free play wasn't adjusted. But even if that's the case I'd suspect something else because a new bearing should be silent even if pedal free play is absent. I'm curious why you found it necessary to adjust the forks as changing a throwout bearing should have no affect on that adjustment.

We adjusted the forks because we thought that may have been part of the problem with the orgional bearing . Which we decided to replace because of the noise when the clutch was depressed.
When we did pull the orgional bearing it was worn out and the spring had broken, so we figured that the noise was from the bearing and replaced with the new bearing and spring.
We adjusted the forks because the manual said that the pressure should be even on all the forks it was, so we just double checked.
I am not a professional mechanic so the issue may be elsewhere.
Thank you for your response.

Is the pedal retracting spring present, in good condition, and hooked in the correct spot on the throwout arm end to keep it and linkage tightly together and out of the way when not needed? Perhaps there is something worn or adjusted out of tolerance and the arm or linkage is actually able to move slightly when at rest.

Did you replace the pilot bearing in the flywheel?

Yes the pedal spring in there andcorrectly attached.
Thank you for the suggestions.
the next post may be the issue.
No we did not replace the pilot bearing.
So i will order one and that will be the next attempt.
I think, hopefully, that should correct the problem.
thanks

I think of that you may have suggested the fix.
No we did not replace the pilot bearing.
WE did not think of that.
Will order one today.
Install next week and;
Keep you posted.

thanks
