REMOVE SYNCHRONIZER RING NO.1
Remove the synchronizer ring No. 1.
REMOVE INPUT SHAFT BEARING
Remove the 13 input shaft bearing from the input shaft assembly.
REMOVE INPUT SHAFT FRONT BEARING
Using a snap ring expander, remove the front bearing shaft snap ring from the input shaft assembly.
Using SST and a press, remove the input shaft front bearing from the input shaft.
INSPECT SYNCHRONIZER RING NO.1
Coat the input shaft cone with gear oil. Check the braking effect of the synchronizer ring No. 1. Turn the synchronizer ring No. 1 one direction while pushing it to the input shaft cone. Check that the ring locks.
If the braking effect is insufficient, apply a small amount of the fine lapping compound between the synchronizer ring No. 1 and the input shaft cone. Lightly rub the synchronizer ring No. 1 and the input shaft cone together.
Note
Ensure the fine lapping compound is completely washed off after rubbing.
Check again the braking effect of the synchronizer ring No. 1.
Using a feeler gauge, measure the clearance between the synchronizer ring No. 1 back and the input shaft spline end.
| Standard clearance |
|---|
| 1.0 to 2.0 mm (0.0394 to 0.0787 in.) |
If the clearance is less than the minimum, replace the synchronizer ring No. 1 and apply a small amount of the fine lapping compound on the input shaft cone.
Note
Ensure the fine lapping compound is completely washed off after rubbing.
