Inspection
1. Clean transmission case thoroughly inside and out with solvent, then clean magnetic disk at bottom of case.

3. Inspect drive gear bearing rollers, reverse idler shaft and spacers.

4. Inspect drive gear bearing roller for chips, cracks or excessive wear. Replace if necessary.

5. Inspect clutch sleeves to ensure free movement on hubs.

6. Clean front and rear bearings thoroughly with solvent. Do not allow bearings to spin. Turn them slowly by hand. Spinning bearings may damage races and rollers.
