Inspection of Input Shaft Component Parts

1. INSPECT SYNCHRONIZER RINGS
a. Check for wear or damage.
b. Turn the ring and push it in to check the braking action.




c. Using a feeler gauge, measure the clearance between the synchronizer ring back and gear spline end.

Minimum clearance: 0.6 mm (0.024 in.)

If the clearance is less than the minimum, replace the synchronizer ring.




2. INSPECT NO.2 SHIFT FORK AND HUB SLEEVE CLEARANCE
Using a feeler gauge, measure the clearance between the hub sleeve and shift fork.

Maximum clearance: 1.0 mm (0.039 in.)

If the clearance exceeds the maximum, replace the shift fork or hub sleeve.




3. INSPECT INPUT SHAFT
a. Check the input shaft for wear or damage.
b. Using a micrometer, measure the outer diameter of the input shaft journal surface.

Minimum outer diameter:
Part A 24.870 mm (0.9791 in.) (C150)
B 28.970 mm (1.1405 in.)
C 30.970 mm (1.2193 in.)
D 24.970 mm (0.9831 in.)

If the outer diameter exceeds the minimum, replace the input shaft.




c. Using a dial indicator, check the shaft runout.

Maximum runout: 0.05 mm (0.0020 in.)

If the runout exceeds the maximum, replace the input shaft.
