## Secondary Gear Shaft

#### 25 x 35 mm Thrust Shim Selection

14-374

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 on the transmission housing.
3. Measure the distance between the transmission housing surface and the thrust shim 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 so that the secondary gear shaft thrust clearance comes into the tolerance.

Secondary Gear Shaft Thrust Clearance:

STANDARD: 0-0.15 mm (0-0.006 in.)

FORMULA:

25 x 35 mm Thrust Shim Thickness:

= Measurement A-Measurement B + Flywheel Housing Gasket Thickness: 0.5 mm (0.020 in.)

Example:

Measurement A: 32.7 mm (1.287 in.)

Measurement B: 30.1 mm (1.185 in.)

25 x 35 mm Thrust Shim Thickness

= 32.7 mm (1.287 in.)-30.1 mm (1.185 in.) + 0.5 mm (0.020 in.)

= 3.1 mm (0.122 in.)

You can select the thickness between 3.1 mm (0.122 in.) and 2.95 mm (0.116 in.).

The thrust shim can be used C or D in this case.

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