M/T Countershaft Assembly Clearance Inspection

M/T Countershaft Assembly Clearance Inspection

1. Measure the clearance between 1st gear (A) and the distance collar (B) with a feeler gauge (C).

- If the clearance exceeds the service limit, go to step 2.
- If the clearance is within the service limit, go to step 4.










2. Measure the length of the 1st gear distance collar as shown.

- If the length is not within the standard, replace the 1st gear distance collar.
- If the length is within the standard, go to step 3.










3. Measure the thickness of 1st gear.

- If the thickness is less than the service limit, replace 1st gear.
- If the thickness is within the service limit, replace the 1st/2nd synchro hub and reverse gear as a set.










4. Measure the clearance between 2nd gear (A) and 3rd gear (B) with a feeler gauge (C). If the clearance exceeds the service limit, go to step 5.










5. Measure the length of the 2nd gear distance collar.

- If the length is not within the standard, replace the 2nd gear distance collar.
- If the length is within the standard, go to step 6.










6. Measure the thickness of 2nd gear.

- If the thickness is less than the service limit, replace 2nd gear.
- If the thickness is within the service limit, replace the 1st/2nd synchro hub and reverse gear as a set.
