Secondary Shaft Disassembly/Inspection/Reassembly

Disassembly








Remove the tapered roller bearings using a commercially available bearing separator and a press as shown.

Inspection
1. Inspect the gear surface and the bearing surface 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 with a new one.
Standard:
A (Ball bearing contact area): 31.002 - 31.013 mm (1.2205 - 1.2210 inch)
B (Propeller shaft end tapered roller bearing contact area): 41.002 - 41.018 mm (1.6142 - 1.6149 inch)
C (Transmission end tapered roller bearing contact area): 35.009 - 35.025 mm (1.3783 - 1.3790 inch)
Service Limit:
A: 30.95 mm (1.219 inch)
B: 40.95 mm (1.612 inch)
C: 38.94 mm (1.376 inch)





3. Inspect for runout by supporting both ends of secondary shaft. Rotate the secondary shaft two complete revolutions when measuring the runout. If the runout is more than the service limit, replace the secondary shaft with a new one.
Standard: 0.02 mm (0.001 inch) maximum
Service Limit: 0.05 mm (0.002 inch)
