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.
|
|
2.Check the needle roller bearing cage for deformation.
