INSPECTION AFTER REMOVAL
CLUTCH DISC
• Measure circumferential runout relative to clutch disc center spline.
If it is outside the specification, replace clutch disc.
• Measure backlash to clutch disc spline and main drive gear spline
at the circumference of clutch disc. If it is outside the specification,
replace clutch disc.
• Measure the depth “A” to clutch disc facing rivet heads, using a
calipers. If it exceeds the allowable wear limit, replace clutch disc.
CLUTCH COVER
• Check clutch cover thrust ring for wear or breakage. If wear or breakage is found, replace clutch cover.
NOTE:
• Worn thrust ring will generate a beating noise when tapped at the rivet with a hammer.
• Broken thrust ring will make a clinking sound when cover is shaken up and down.
• If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace clutch cover.
