8. Final Drive Shaft Disassembly & Service
Final Drive ShaftThrust Clearance Inspection
NOTE: If the transmission housing, flywheel housing, final drive shaft, secondary driven gear, or 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 bearing inner race surface, then note the measurement (measurement E).
4. Calculate the final drive shaft thrust clearance using the formula:
Clearance
= Measurement D-Measurement E+Flywheel housing gasket thickness (0.5 mm)
Standard: 0 - 0.15 mm (0 - 0.006 inch)
NOTE: The standard of the clearance includes thickness of the flywheel housing gasket (0.5 mm, 0.02 inch)
5. If the clearance is out of standard, select a 25 x 35 mm thrust shim from the table.
