CLUTCH RELEASE BEARING
Inspect the release bearing for any abnormality, parti-
calarly cracks, to decide whether it can be reused or
should be replaced.
Smooth engagement and disengagement of the clutch
depends much on the condition of this bearing.
SHIFTING FORK AND GEAR
Using a thickness gauge, check the shifting fork clearance
in the groove of its gear. If the clearance limit is exceed-
ed by any of the three gears, determine whether the
gear or the gear shifting fork should be replace by mea-
suring the thickness and groove width.
