Clearance Inspection

1. Measure the clearance between 2nd and 3rd gears.

Standard:   0.06-0.21 mm (0.002-0.008 in) Service Limit: 0.33 mm (0.013 in)

2. If the clearance exceeds the service limit, measure the thickness of 3rd gear.

Standard:   30.22-30.27 mm (1.190-1.192 In) Service Limit: 30.15 mm (1.187 In)

If the thickness of 3rd gear is less than the service limit, replace 3rd gear with a new one. If the thickness of 3rd gear is within the service limit, replace the 3rd/4th synchro hub with a new one.
3. Measure the clearance between 4th gear and the spacer collar.

Standard:   0.06-0.19 mm (0.002-0.004 in) Service Limit: 0.31 mm (0.012 in)

4. If the clearance exceeds the service limit, measure distance ® on the spacer collar.

Standard:   22.83-22.86 mm (0.899-0.900 in) Service Limit: 22.81 mm (0.898 in)

5. If distance ® Is more than the service limit, replace the spacer collar with a new one. If distance ® is within the service limit, measure the thickness of 4th gear.

Standard:   30.12-30.17 mm (1.186-1.188 In) Service limit: 30.05 mm (1.183 In)

If the thickness of 4th gear is less than the service limit, replace 4th gear with a new one. If the thickness of 4th gear is within the service limit, replace the 3rd/4th synchro hub with a new one.
