1.Check the helical gear
teeth and clutch gear teeth of each input shaft sub-assembly
for damage and excessive wear.
2.Check the
synchronizer cone surface of each input shaft sub-assembly
for roughness,
damage, and excessive wear.
3.Check the inside
surface and front and back sides of each input shaft
sub-assembly
for damage and excessive wear.

1.Check the clutch gear on
the synchronizer ring for damaged and missing
teeth.
2.Check the synchronizer ring inner cone
surface for damage or wear. Also check that
the inside ridges are intact.
|
|
3.After applying oil to the
taper portion on gear, press and fit the synchronizer ring
by
hand. Confirm the synchronizer ring cannot be
rotated.
|
|
4.Using the thickness gauge,
check the clearance between the synchronizer ring and the
4th
gear.
Standard value: 0.70 - 1.70
mm
Minimum limit: 0.70 mm

1.Combine the needle roller
bearing with the input shaft, and check that it rotates
smoothly without noise or play.
