Inspection

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




2. Inspect for runout.

Standard: 0.02 mm (0.0008 in) max.
Service Limit: 0.05 mm (0.002 in)

NOTE: Support the countershaft at both ends as shown.

- If the runout is more than the service limit, replace the countershaft with a new one.
