[QUOTE="Bad Company, post: 15335602, member: 141815"] Let me clarify something to the OP To date you haven't complained about having a hard time getting the car out of gear with the engine running and the clutch depressed while at a stop. You haven't complained about smelling a hot clutch after driving the car in around town driving where you're stopping and starting from traffic lights and stop signs. You haven't complained about the car wanting to creep forward at a traffic light with the clutch depressed and no pressure on the brake pedal. These would all be signs of clutch problems where the air gap from the pressure plate to the flywheel isn't opening up to the proper amount, when you depress the clutch. I don't know what the proper air gap is on the factory clutches. But I'm willing to bet it is 0.100" or less. A Spicer Easy Pedal II clutch assembly in a semi truck with a 15.5" dual disc clutch similar in a lot of ways to the ones in these cars. When the clutch pedal is depressed they have a total air gap of 0.080". Now that is all the pressure plate moves away from the flywheel when the clutch is depressed to releave the pressure plate clamp load on the friction discs of the clutch assembly. Divide that by the number of discs, which is 2 = 0.040". Now you still have divide that number in half to have each disc centered between the steel plates, which is now a 0.020" air gap on each side of each friction disc if everything is centered properly for zero contact between the stationary and moving parts of the clutch assembly. The friction discs of this clutch or any other clutch will not move away from the steel plate surfaces without the centrifugal forces of the engine rotating the clutch assembly at idle speeds or higher. So as you depress the clutch the friction discs stay with the flywheel and the second friction disc is more than likely touching the intermediate plate. You're hearing these discs move as the car moves Otherwise you would be complaining about the list of things I've mentioned and it won't be long before the clutch fails. [/QUOTE]
