Clutch sticking?
Hi,
I'm concerned about my clutch and the possible consequences for the gearbox in my 82 SC. My Pgarage has a little slope. When the car has been standing some time in the garage and I depress the clutch pedal, the car does not start to roll. Even worse, it is difficult to get it out of gear (I always park with 1st gear engaged) and during shifting in neutral there is a sound I don't like. Engine is not started yet. Before I start I shift in reverse, than start the car drive reverse and turn the car on my driveway. After this few meters driving the car, the clutch is OK. I think that the clutch is not disengaging. Could it be that the clutch disc is sticking to the flywheel ? is the TOB not functioning? Is there a way to check this? Tx, dede |

Has the car been stored and not driven? If that is the case the clutch disk can rust and stick to the flywheel. Alternatively, the clutch may be out of adjustment or there could be clutch cable or pedal cluster problems.

Jim,
Tx for your reply. This "sticking "problem hapens every time I take the car for a drive. As soon a I have driven a few meter, it is ok and I can shift. The cable travel on the tranny side is 25 mm. Does this mean that the cable is Ok, or are other cable issues possible? dede |

Unless the driving episodes are few and with long intervals between and your garage is very damp I doubt your clutch is rusting to the flywheel each time. The clutch pedal "free play" of 25 mm is measured at the pedal not at the transmission. How much free play is there at the clutch pedal? The car may have a bent or cracked clutch fork arm combined with a worn guide tube (tube the release bearing slides on).

Jim,
I have been driving the cat this afternoon around 14h00.Now it is 20h30 in my place. I just went to the garage and did the test: I pressed the clutch pedal. Result: car does not move... The 25 mm I measured is the travel the cable makes on the tranny side. What can I measure on the pedal side? What I don't understand is that after driving the car maybe 50m, the clutch is not "sticking" anymore... Who can explain this???? dede |

"What can I measure on the pedal side?"
Measure between the back of the pedal pad and the floor; there should be 25 mm of free play there with a properly adjusted clutch. Free play is distance the pedal moves before encountering significant force. There also may be a possibility the input shaft pilot bearing is sticking and after some movement it releases - expansion from heating due to friction? Has there been any transmission/clutch work done to the car recently? |

Jim,
I have this car 1 year and this "sticking" has always be an issue. As far as I'm aware there has been no trans or clutch work done in the recent past. At least I can not find any bill in the history of the car that is pointing in this direction. The pilot bearing idea is a good one... Any other experts sharing this idea? Any way to inspect this? Tx, dede |
