CLUTCH COVERNJCL0032S02+Check clutch cover installed on vehicle for unevenness of dia-
phragm spring toe height.
Uneven limit:
MODEL 200, 215 0.8 mm (0.031 in)
MODEL 240 0.7 mm (0.028 in)
+If out of limit, adjust the height with Tool.
AEM100
FLYWHEELNJCL0032S03+Check contact surface of flywheel for slight burns or discolora-
tion. Repair flywheel with emery paper.
+Check flywheel runout.
Maximum allowable runout:
Refer to EM-62, ªFlywheel/Drive Plate Runoutº (QG
engine models), and EM-154, ªFlywheel Runout (YD
engine models)º.
