Output Shaft: Inspection

INSPECT NO. 1 SYNCHRONIZER RING
1. Check for wear or damage.
2. Check the braking effect of the synchronizer ring. Turn the synchronizer ring in one direction while pushing it to the gear cone. Check that the ring locks.
  If the braking effect is insufficient, apply a small amount of the fine lapping compound between the synchronizer ring and gear cone. Lightly rub the synchronizer ring and gear cone together.
  
  NOTE: Ensure the fine lapping compound is completely washed off after rubbing.
3. Check again the braking effect of the synchronizer ring.

4. Using a feeler gauge, measure the clearance between the synchronizer ring back and gear spline end.
  Minimum clearance: 0.75 mm (0.0295 in.)
If the clearance is less than the minimum, replace the synchronizer ring, and apply a small amount of the fine lapping compound on gear cone.

NOTE: Ensure the fine lapping compound is completely washed off after rubbing.

INSPECT NO. 2 SYNCHRONIZER RING
1. Check for wear or damage.
2. Check the braking effect of the synchronizer ring. Turn the synchronizer ring in one direction while pushing it to the gear cone. Check that the ring locks.
  If the braking effect is insufficient, replace the synchronizer ring.

3. Using a feeler gauge, measure the clearance between the synchronizer ring back and gear spline end.
  Minimum clearance: 0.70 mm (0.0276 in.)
If the clearance is less than the minimum, replace the synchronizer ring.

INSPECT NO. 1 GEAR SHIFT FORK AND REVERSE GEAR CLEARANCE
Using a feeler gauge, measure the clearance between the reverse gear and gear shift fork.

Maximum clearance: 0.35 mm (0.014 in.)

If the clearance exceeds the maximum, replace the gear shift fork or reverse gear.

INSPECT OUTPUT SHAFT

Check the output shaft for wear or damage.

Using a micrometer, measure the journal diameter.

Minimum journal diameter:

MINIMUM JOURNAL DIAMETER TABLE

Part A (Roller bearing)	32.985 mm (1.2986 in.)
Part B (1st gear)	37.985 mm (1.4955 in.)
Part C (2nd gear)	31.985 mm (1.2592 in.)

If the journal diameter is less than the minimum, replace the output shaft.

Fig 6: Inspecting Output Shaft

Using a dial indicator, check the shaft runout.
Maximum runout: 0.03 mm (0.0012 in.)

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