RemovalNJCL00451. Remove manual transaxle from vehicle. Refer to MT-24,
ªRemovalº.
2. Move withdrawal lever enough to remove release bearing, and
remove release bearing from clutch lever.
3. Support clutch lever claws with an appropriate wood block,
align retaining pin with A in the figure, and drive out spring pin
using a pin punch.
4. Pull out withdrawal lever and remove clutch lever.

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.
+Clean old grease and abrasive materials off the grease
application area.
