Transfer Gear Inner Bearing Installation

The work area, counter surfaces and tools must be thoroughly cleaned before attempting to assemble the 948TE transmission. All of the sub assemblies should be disassembled, cleaned, and assembled with new sealing components where applicable. The transmission housing should be clean and oil free before beginning this procedure. If the transmission was contaminated with metallic material, all of the thrust bearings and roller bearings should be replaced. The bearing in the output gear support assembly is not serviceable. The output gear support assembly should be replaced if metal debris is present.

   NOTE:

   If a new transfer gear (1) or transmission housing are being used, measurements must be preformed to determine correct thickness for the bearing preload shims

   Refer to STANDARD PROCEDURES .

   If the bearings and races are replaced the factory installed preload shims do not require replacement.

8. If necessary, replace the bearings and races on the transfer gear (1).
9. Install the transfer gear (1) into the transmission housing.
