Inspection and Adjustment After Removal
INSPECTION AND ADJUSTMENT AFTER REMOVALClutch Disc
^ Check clutch disc for backlash of spline and runout of facing.
Maximum facing runout
MR20DE: 1.0 mm (0.039 in)
QR25DE: 0.7 mm (0.028 in)
Distance of runout check point (from hub center)
MR20DE: 215 mm (8.46 in)
QR25DE: 230 mm (9.06 in)
^ Check clutch disc for burns, discoloration or oil or grease leakage. Replace if necessary.
^ Measure backlash to clutch disc spline and input shaft spline at the circumference of clutch disc. If outside the specification, replace clutch disc.
Maximum allowable spline backlash: 1.0 mm (0.039 in) (at outer edge of disc)
^ Use a suitable tool to measure the depth to clutch disc facing rivet heads. If it exceeds the allowable wear limit, replace clutch disc.
Wear limit of facing surface to rivet head: 0.3 mm (0.012 in)
Clutch Cover
Check clutch cover installed on vehicle for unevenness of diaphragm spring toe height.
Uneven limit: 0.7 mm (0.028 in) or less
Tool number A: ST20050240 ( - )
^ If out of limit, adjust the height using Tool (A).
^ Check clutch cover thrust ring for wear or breakage. If wear or breakage is found, replace clutch cover assembly.
NOTE:
^ Worn thrust ring will generate a beating noise when tapped at the rivet with a suitable tool.
^ 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 the assembly.
Flywheel Runout
^ Check contact surface of flywheel for slight burns or discoloration. Repair flywheel with emery paper.
^ Check the flywheel runout.
CAUTION: Measure flywheel outer face (not on knock pin and clutch cover mounting hole).
