Car Forum / Porsche / Porshe 911 / January 2008Different from any clutch question I've seen.
I have a 1978 911 SC, sold in Europe, ie. a gray market car. I''ve had it since 83 and will probably die with it. Last winter I rebuilt the top end and replaced the clutch, pressure plate, flywheel, throw out bearing, and cable. Since then I have not been able to properly adjust the clutch. It seems almost as tho the pressure plate is 5mm too tall in that I must remove the space in the adjuster bolt and foot, then turn the adjusting bolt in another 1 1/2 turn to get the clutch to come off the flywheel. At the same time the clutch pedal engages and releases the clutch at about 2 inches off the floor. I've had 3 knowledgeable people attempt to adjust this clutch all with the same results. Is it probable, since this is grey market and I bought the parts from Performance Products that I simply have the wrong parts, stateside instead of European? Any Ideas or information would be greatly appreciated. Thanks, Rick if you replaced clutch and flywheel and pressure plate all at once, I don't see how that can be an issue - is it possible that there are two notches where you hook up the cable and you used the wrong one? I don't know your car but I had that happen on a different car once - I think what you are describing sounds like a too short clutch fork. Do you have the Porsche manual for your car? do you have PET6? both those can help confirm correct parts, but this sounds to me like some kind of assembly error >I have a 1978 911 SC, sold in Europe, ie. a gray market car.

Assuming the parts were assembled properly, and the cable is good, throw out the manual when it comes to adjusting the clutch. I've never been happy with the clutch adjusted to "specs." It engages right at the top of the peddle, just before my knee bangs into the steering wheel. I like it adjusted so that it engages early, allowing me to get my foot off of it early. My mechanic has strict instructions not to touch the clutch adjustment without my permission. There are those damn specs, and there is a clutch that disengages and engages but is very drivable. If the car had to be left at specs, and I had no leeway, I'd sell it.
