Inspection

1. Inspect the gear surface and bearing surface for wear and damage, then measure the countershaft at points A, B, and C.
- If any part of the countershaft is less than the service limit, replace it with a new one.




2. Inspect for runout.

Standard: 0.02 mm (0.001 in) max.
Service Limit: 0.05 mm (0.002 in)

NOTE: Support the countershaft at both ends as shown.

- If the runout exceeds the service limit, replace the countershaft with a new one.
