INPUT SHAFT COMPONENT PARTS INSPECTION
1. Inspect synchronizer ring.
a. Check for wear or damage.
b. Check the braking effect of the synchronizer ring.
-
Turn the synchronizer ring in one direction while pushing it to the gear cone. Check that the ring locks.
-
If the braking effect is insufficient, apply a small amount of fine lapping compound between the synchronizer ring and gear corpse. Lightly
rub the synchronizer ring and gear cone together.
NOTICE: Ensure the fine lapping compound is completely washed off after rubbing.
c. Check again the braking effect of the synchronizer ring.
d. Using a feeler gauge, measure the clearance between the synchronizer ring back and gear spline end.
-
Minimum clearance: 0.6 mm (0.024 inch).
If the clearance is less than the minimum, replace the synchronizer ring and gear cone by applying a small amount of fine lapping
compound.
NOTICE: Ensure the fine lapping compound is completely washed off after rubbing.
2. Inspect shift fork and hub sleeve clearance.
-
Using a feeler gauge, measure the clearance between the hub sleeve and shift fork.
Maximum clearance: 1.0 mm (0.039 inch).
If the clearance exceeds the maximum, replace the shift fork or hub sleeve.
3. Inspect input shaft.
