1. Heat inner race for tapered roller bearing to about 120°C (250°F) and press on.
2. Press on 4th gear, whereby collar faces 3rd gear.
Note: It is essential to keep to the following procedures, since the press fit gear takes the engine torque. Clean gear and shaft with a greaseless
cleaning solution to remove all oil and grease, and heat gear on a hot plate to about 120°C (250°F). Press on gear and press again after
transfer of heat (approx. 3 minutes).
3. Adjust axial play on 4th gear (gear must be cold and pressed against stop). Measure and install the thickest possible circlip. Axial play may be
max. 0.02 mm.
Note: Perform work very conscientiously, since otherwise service life of tapered roller bearings could be impaired.
