INPUT SHAFT INSPECTION
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 synchroni-zer ring and gear cone.
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.If it does not lock,replace the synchronizer

ring.

(d)Using a feeler gauge,measure the clearance between the synchronizer ring back and gear spline end.
Minimum clearance:
0.5 mm(0.020 in.)
HINT:When replacing either a synchronizer ring or gear,apply a small amount of fine lapping compound between the synchronizer ring and gear cone.
Lightly rub the synchronizer ring and gear cone together.
NOTICE:
.When replacing both the synchronizer ring and gear,there is no need to apply any compound or to rub them
together.
.NOTICE:Ensure the fine lapping compound is completely washed off after rubbing.

BEARING REPLACEMENT换轴承
