I Just Put In A New Zoom Stage 4 Racing Clutch.. It Worked Great For A While But Now Everytime I Go From A Dead Stop The Clutch Gives Off A Loud Annoying Squeal And It Bugs.. What Could Be The Problem And How Could I Fix It.. Thanks!!

What did you do for a flywheel?

In addition to the flywheel question:
1) Did you make sure there were no leaks from the engine, such as the rear main?
2) Did you lube the pilot bearing and the transmission shaft with the correct lube (comes with many clutch kits)
3) Did you clean the clutch AFTER bolting it to the flywheel? Such as with brake-clean, etc?

also did you change the throw out bearing and piolet bearing when you did the clutch.

yeah i did all that.. i replaced the rear main seal and lubbed everthing with the correct lube and i machined the flywheel so that was cherry.. i replaced the throw out and the pilot bearing..so i have no idea...

Then you are left with only a few possibilities:

1) The clutch isnt broken in. Some high performance clutches will chatter and do odd things until broken in. You might call Zoom and ask for specific break in periods for your model clutch.

2) Improper break in/getting on it/slipping it too early in its life. This results in outgassing of the bonding material and glazes the disc causing the problem you have. Solution is to (try) pretending the clutch is new and doing the break in all over. Sometimes you will get lucky and it will smooth out, other times you are looking at doing the job again.

3) Disc/Pressure plate/flywheel contamination. If too much grease was applied it can fling off under high RPM conditions, resulting in contamination. Can also happen if the disc didnt get all the way degreased after being bolted up. (Rare is a disc that doesnt somehow get some grease on it while working.)

4) Maybe something went wrong with the machining, in which case you would be doing the job again.

Hope this helps - keep us posted.
