M/T Countershaft Assembly Clearance Inspection

M/T Countershaft Assembly Clearance Inspection

1. Measure the clearance between 1st gear (A) and the 1st gear 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 the reverse gear as a set.










4. Measure the clearance between 2nd gear (A) and 3rd gear (B) with the 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 the reverse gear as a set.
