Secondary Gear Shaft Thrust Shim Selection

1. Measure the distance between the flywheel housing surface and the ball bearing as shown, then note the measurement (Measurement A).
2. Install the secondary gear shaft the transmission housing.





3. Measure the distance between the transmission housing surface and the thrust washer mounting surface of the secondary gear shaft as shown, then note the measurement (Measurement B).
4. Calculate 25 x 35 mm thrust shim thickness by following formula. Formula: 25 x 35 mm Thrust Shim Thickness = Measurement A - Measurement B + Flywheel Housing Gasket Thickness: 0.5 mm (0.020 inch) Example:
- Measurement A: 32.7 mm (1.287 inch)
- Measurement B: 30.1 mm (1.185 inch)
- 25 x 35 mm Thrust Shim Thickness = 32.7 mm (1.287 inch) - 30.1 mm (1.185 inch) + 0.5 mm (0.020 inch) = 3.1 mm (0.122 inch)
- Select 25 x 35 mm Thrust Shim D.





5. Select the 25 x 35 mm thrust shim from the following the table.
