14-15. Cleaning, Inspection, and Repair
a. Clean all parts with an approved cleaning
solvent and dry thoroughly.
b. Inspect pressure plate for heat discoloring,
warped condition, or excessive wear at the driving slots.
Replace a defective pressure plate.
c. If needle hearings must be replaced, press on
end of bearing on which part number is stamped
d. Inspect disc assemblies for excessive
distortion, cracks or breaks, and hub spline wear
Replace defective disc assembly.
e. Inspect flywheel ring cover for cracks,
distortion, and driving lug wear. There should not be less
than 0.004 inches or over 0.010 inches movement
between driving lug contact surface and pressure plate
slots. Replace a defective flywheel ring cover.
f. Inspect intermediate plate for worn driving
slots and cracks in friction surfaces. There should not be
less than 0.006 inches or over 0.014 inches movement
between intermediate plate slot contact surfaces and the
drive pins in flywheel rim. Replace defective
