Clutch chatter solution suggestions by Doug Waldrick, 9225 Indian Creek Road South, Indianapolis, IN 46259 317-862-4171 mailto:drdoug@ameritech.net The fingers on pressure plate must be correct height, from top of the cover, with the new disc installed. This measurement should be no more than 1.450, and the fingers should be set at .010-MAX ., variations between them. If this isn't done correct, the clutch will probably chatter. DON'T FORGET THE FLUID IN THE CLUTCH
Following items to check for clutch chatter (other than pressure plate and clutch Disc)
* Check for cracked bell housing (usually passenger side of bell housing starting at cross shaft)
* Input shaft excessively worn at pilot bearing end.
* Input shaft (twisted and/or excessively loose-front transmission bearing excessively loose)
* Clutch cross over shaft bushings (usually worn excessively)
* Alignment of transmission with engine (bell housing bolt up surface free of dirt)
* Back of block cleaned and dowels secured in place.
* Engine and transmission mounts are good and solid. (not soft-very important for proper clutch operation.
* Flywheel resurfaced correctly and torqued at correct specs with clean flange on crank and flywheel. Use soft setting Permatex and seal flywheel to crank flang (thin coat)
* Throw out bearing fork not worn (what did old throw ought bearing look like-worn spots in bearing housing)
* Engine tune (is it running properly)
Above items are not necessarily in order-each vehicle is different!\
