ISSUE:
The pocket bearing (tapered roller bearing between the input shaft and main shaft) may be damaged from insufficient lubrication at initial
start-up during engine idle. Inspection of failed components has revealed that in some cases the oil baffle was either missing or improperly
positioned.
ACTION:
If service is required and the transmission is opened up, use the following pocket bearing lubrication inspection procedure.
1.
Make sure the oil baffle is installed in the input shaft synchronizer cone recess. Refer to the 1988 Light Truck Shop Manual, Volume A, Section
16-34-8, Item 36.
2.
Inspect the oil baffle for tears or damage.

3.
Be sure the oil baffle lip is recessed 0.24" (6 mm) below the synchronizer cone edge, Figure 17.
4.
Make sure the oil baffle fits tightly and cannot be moved by hand.
5.
Check to see that the three (3) lubrication holes in the input shaft are free of any obstructions.
6.
Make sure the oil channel (in the main case) to the input shaft bearing is free of any obstruction.
7.
Make sure the oil retainer ring behind the outer race of the input bearing is free of damage.
8.
Check to see that the synchronizer body snap ring forward of the 3/4 synchronizer package on the main shaft is in position.
