InspectionNJCL0046+Replace the release bearing if it is seized, damaged, faulty in
rotation direction, or has poor aligning function.
+Replace the withdrawal lever if its contact surface is worn
abnormally.
+Replace the clutch lever if its contact surface is worn abnor-
mally.
+Replace the dust seal if it is deformed or cracked.
InstallationNJCL0047CAUTION:
+Be sure to apply grease to the clutch components.
Otherwise, abnormal noise, poor clutch disengagement,
or clutch damage may occur. Wipe the excess grease off
completely, because it may cause the clutch components
to slip and shudder.
+Keep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.

grease evenly on the sliding part of the clutch lever and
the release bearing spring.
+Apply just enough clutch sleeve grease to fill up the
release bearing inner groove.
+Apply the clutch grease to the clutch disc and the input
shaft spline. Install the clutch disc to the input shaft,
remove the excess grease around the shaft, and remove
the clutch disc.
+Lightly and evenly apply the clutch sleeve grease on the
sliding part of the release bearing, install the release
bearing, remove the excess grease around the bearing,
and remove the release bearing.
