CVT Final Drive Shaft Thrust Clearance Inspection

CVT Final Drive Shaft Thrust Clearance Inspection

NOTE: If the transmission housing, the flywheel housing, the final drive shaft, the secondary driven gear, or the final drive shaft bearing is replaced, the final drive shaft thrust clearance must be adjusted with a 25 x 35 mm thrust shim.

1. Install the secondary driven gear (A) on the final drive shaft (B), then install the final drive shaft in the transmission housing. Install the existing 25 x 35 mm thrust washer (C).

2. Measure the distance (D) between the transmission housing surface and the thrust shim surface on the final drive shaft, then note the measurement (measurement D).

3. Measure the distance (E) between the flywheel housing surface and the bearing inner race surface, then note the measurement (measurement E).

4. Calculate the final drive shaft thrust clearance using the formula:









NOTE: The standard of the clearance includes thickness of the flywheel housing gasket (0.5 mm, 0.02 in)

5. If the clearance is out of standard, remove the 25 x 35 mm thrust shim, and measure its thickness.

6. Select a new 25 x 35 mm thrust shim from the following table and install it, then recheck that the clearance is within the standard.
