REALLY NEED YOUR HELP WITH CLUTCH
Okay...I have a 1982 SC...not sure if it has one of the dreaded rubber center clutchs
My problem is the clutch does not seem to disengage properly and thus I cannot shift the car without grinding gears... I noticed that even with the clutch to the floor, my car would move if in first...but the clutch was slipping because the car was shuddering like you would not believe So I thought it was a clutch cable adjustment problem. So I went through the whole adjusment procedure per the Bentley Manual... Now if I clutch there is a shrilling HIGH pitched noise...if I get off the pedal it goes away, but will come back periodically... Now one thing I noticed was that with no tension on the cable (ie disconnected) the adjustment screw was nearly bottomed out to reach the required 1.2mm clearence... Are these two parts supposed to be this far apart? Please help? Do I need a new clutch? I really do not want to have to take it to my 86 dollar an hour porsche mechanic... Thanks MJ |

Mine is hydraulic but if experience with previous cars helps then here goes.
If noise goes when clutch is engaged but is there when clutch is depressed I would suggest (and this is from other cars - no specific porsche knowledge) that your release bearing is not releasing properly and when unloaded is spinning with the engine. If your noise is engine speed related then this could be the case. Cure is to slacken off on the adjustment if you can (ie move bearing away from clutch at rest) Don't know if this helps but at least it moves you up the board!! Roy |

Same thing occurred on my '79 some years ago. It was the throw out bearing. It starts to disintegrate and that causes an inability to fully release the clutch and shifting becomes almost impossible. The squealing is scary. Give yourself a week to drop the engine and do the job yourself or with the help of a friend.
Just don't follow the directions to release the tension with the adjusting screws on he flywheel. Remove the short activating arm from the release fork shaft and the engine and tranny will separate. |

the release fork in the bellhousing may have cracked. common problem. the chatter you describe is a symptom, especially if it didn't do it before. adjusting the cable tighter will do no good if that's the case. the TO bearing gets pulled at an angle, so it won't entirely release and might squeel.
