M/T Secondary Shaft Inspection

M/T Secondary Shaft Inspection

1. Inspect the gear and bearing contact areas for wear and damage.

2. Measure the countershaft at points A, B, and C. If any part of the secondary shaft is less than the service limit, replace it.










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