14. Countershaft Inspection

Countershaft Inspection





1. Inspect the oil passage, gear, and bearing surfaces for wear and damage, then measure the countershaft at points A, B, C, and D. If any part of the countershaft is less than the service limit, replace it.





2. Inspect the runout by supporting both ends of the countershaft. Then rotate the countershaft two complete turns while measuring with a dial gauge. If the runout exceeds the service limit, replace the countershaft.
