INSPECTION AFTER REMOVAL
CLUTCH DISC
• Measure circumferential runout relative to clutch disc center spline.
If it is outside the specification, replace clutch disc and clutch cover
as a set.
• Measure backlash to clutch disc spline and main drive gear spline
at the circumference of clutch disc. If outside the specification,
replace clutch disc and clutch cover as a set.
• Measure the depth “A” to clutch disc facing rivet heads using cali-
pers. If it exceeds the allowable wear limit, replace clutch disc and
clutch cover as a set.
CLUTCH COVER
Check diaphragm spring lever claws for unevenness with the lever
still on the vehicle. If they exceed the tolerance, adjust lever height
using the diaphragm adjusting wrench [SST: ST20050240 (
—
)].
• Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch disc and clutch cover as a set.
