CVT Final Drive Shaft Thrust Clearance Inspection and 25 x 35 mm Thrust Shim Selection

NOTE: If the transmission housing, flywheel housing, final drive shaft, secondary driven gear, or final drive shaft bearing is replaced, select the 25 x 35 mm thrust shim to adjust the final drive shaft thrust clearance.

1.Measure the distance (A) between the flywheel housing surface and bearing inner race surface, then note the measurement (Measurement A).



2.Install the secondary driven gear on the final drive shaft, then install the final drive shaft in the transmission housing.

3.Measure the distance (B) between the transmission housing surface and the thrust shim mounting surface on the final drive shaft, then note the measurement (Measurement B).



4.Measure the 25 x 35 mm thrust shim thickness, and check the final drive shaft thrust clearance by calculation from the below formula.

 Thrust Clearance Standard:
0-0.15 mm (0-0.006 in.) 

Final Drive Shaft Thrust Clearance 
= Measurement A - Measurement B + Flywheel Housing Gasket Thickness (0.5 mm) 
-25 x 35 mm Thrust Shim Thickness (measured) 

5.If the clearance is out of standard, select the new 25 x 35 mm thrust shim within the tolerance from the following table.
