Default Re: Standard vs HD Clutch Disc

My suggestion:

What ever clutch disc you use, make sure it has retainers around each of the six springs on both sides

If you have the flywheel clutch surface machined, have the machinist restore the factory dimension between the clutch surface and the ridge the pressure plate bolts to; 1.123" is the factory dimension.

Make sure the flywheel has not been machined too many times such that the springs in the disc will contact the four flywheel mounting bolts. Before installing the clutch coat the heads of the bolts with chalk. Place the disk on the clutch surface of the flywheel and rotate it to see if any chalk transfers to the springs. It helps to grind a little metal off the heads of the four bolts.

Once the clutch is installed on the flywheel check, and adjust if necessary, the fingers of the pressure plate. They should be between 5\8" and 3\4", 11\16" being nominal. They all should be adjusted even.
