Clutch Pressure Plate and Disc Runout

CLUTCH PRESSURE PLATE AND DISC RUNOUT

Check the clutch disc before installation. Axial (face) runout of a new disc should not exceed 0.50 mm (0.020 inch). Measure runout 6 mm (0.24 inch) from outer edge of disc facing.

A warped pressure plate or diaphragm spring will cause grab and incomplete release or engagement. Be careful when handling the plate and disc. Impact can distort the plate, diaphragm spring, release fingers and hub of the clutch disc.

CAUTION: Use alignment tool when positioning the disc on the flywheel. This will prevent accidental misalignment which could result in plate distortion and disc damage.

NOTE: Clutch plate distortion (and consequent misalignment) can result from improper bolt tightening.
