Service Specifications

Pressure Plate and Clutch Disc






Check the diaphragm spring fingers for height using the special tool and feeler gauge. If the height is more than the service limit, replace the pressure plate and clutch disc as a set.






Inspect for warpage using a straight edge (A) and a feeler gauge (B). Measure across the pressure plate (C). If the warpage is more than the service limit, replace the pressure plate and clutch disc as a set.






Measure the clutch disc thickness. If the thickness is less than the service limit, replace the clutch disc and pressure plate as a set.






Measure the rivet depth from the clutch disc lining surface (A) to the rivets (B) on both sides. If the rivet depth is less than the service limit, replace the clutch disc and the pressure plate as a set.






Be careful not to damage the pressure plate (A). Tighten (180 degrees apart) the pressure plate mounting bolts (B) in a star pattern in several steps.


Flywheel






Measure the flywheel (A) runout using a dial indicator (B) through at least two full turns with the engine installed. Push against the flywheel each time you turn it to take up the crankshaft thrust washer clearance. If the runout is not within the standard, replace the flywheel, and recheck the runout. Resurfacing the flywheel is not recommended.






Install the special tool, then torque the flywheel mounting bolts in a crisscross pattern in several steps.
