Bearing Outer Race Replacement

• Check that there is no clearance between the outer race, shim and transmission housing.
• Install the gasket when checking preload.

4. With the mainshaft, countershaft and secondary shaft removed, install the differential assembly and torque the transmission housing.

Torque = 55 Nm

5. Rotate the differential assembly in both directions to seat the bearings.

A Torque Wrench

6. Measure the starting torque of the differential assembly with the special tool and a torque spanner.

Standard:
New bearings = 2.8 – 4.0 Nm.
Reused bearings = 2.5 – 3.7 Nm.

Note:

• Measure the starting torque at normal room temperature in both directions.
• If out of specification, select two thrust shims which will give the correct preload, and repeat steps given above.
• Changing one of the shims to the next size will increase or decrease starting torque about 3 – 4 kg.cm.
• To increase the starting torque, increase the thickness of shims. To decrease the starting torque, decrease the thickness of shims.

CAUTION: Never use more than two shims to achieve correct pre - load.

Bearing Outer Race Replacement

A Taper Roller Bearing Outer Race
B Heat Gun
C Torque Converter Housing

1. Remove the bearing outer race from the torque converter housing by heating the housing to about 100°C with a heat gun.

CAUTION: Do not heat the housing in excess of 100°C.

Note:

• Replace the bearing with a new one whenever the outer race is to be replaced.
• Do not use shims on the torque converter housing side.
• Adjust preload after replacing the bearing outer race and bearing.

2. Install the new bearing outer race flush with the housing, using the special tools.
