Replace the clutch discs if warped, worn, scored,
burned or charred, or if the facing is flaking off. Re­
place the steel plates if heavily scored, warped, or
broken. Be sure the driving lugs on the plates are in
good condition. The lugs must not be bent, cracked or
damaged in any way.
Replace the clutch spring and spring retainer if ei­
ther is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The
steel plates should slide freely in the slots. Replace
the retainer if the grooves are worn or damaged.
Check action of the check ball in the retainer (Fig.
54). The ball must move freely and not stick.
inspect the clutch retainer bushings carefully
(Fig. 55). The retainer bushings are not service­
able. It will be necessary to replace the retainer
if either bushing is scored, or worn.
Inspect the piston and retainer seal surfaces for
nicks or scratches. Minor scratches can be removed
with crocus cloth. However, replace the piston and/or
retainer if the seal surfaces are seriously scored.
