Lubrication Procedure
Armature bearings and the driveshaft support bearing are permanently lubricated. Do not add lubricant to these bearings. Use GM P/N 1960954 grease
lubricant or the equivalent in order to lubricate the following areas during assembly. Avoid using excessive lubrication.
-
The drive end housing bushing in the drive housing
-
The pivot hole and the working surface on the ends of the shift lever
-
The following components on the driveshaft:
-
The internal gear
-
The shaft
-
The spline
Driveshaft and Clutch Assembly
If disassembled, position the driveshaft on a work surface with the internal gear end down. Assemble the driveshaft and clutch group in the following
way:
IMPORTANT: If the center support bearing is being replaced, install the center support bearing on the driveshaft.
1. Install the driveshaft support to the driveshaft, seating the bearing in the support.
2. Install the clutch drive assembly to the driveshaft.
3. Install the new pinion stop onto the driveshaft.
-
Slide the pinion stop onto the driveshaft until the recess for the stop rings faces up.
-
Install the stop rings into the groove in the driveshaft.
-
Pick the assembly up. Support the assembly under the pinion stop. A metal block, with a U-shaped cutout that will slide over the shaft between
the pinion gear and stop, can be clamped in a vise order to provide support.
-
Ensure that the stop rings are seat fully in the pinion stop recess.
-
Stake the upper edge of the pinion stop over the stop ring at 4 equally spaced places.
Do not allow the staked metal to contact the driveshaft.
