Honda Accord: Mainshaft Assembly Clearance Inspection

1. Support the bearing Inner race with an appropriate sized socket ( A ) , and push down on the mainshaft ( B ) .

2. Measure the clearance between 2nd gear (C) and 3rd gear (D) with a feeler gauge (E).

- If the clearance exceeds the service limit, go to step 3.

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

Standard: 0.06-0.16 mm (0.002-0.006 in)

Service Limit: 0.25 mm (0.010 in)

3. Measure the thickness of 3rd gear.

- If the thickness is less than the service limit, replace 3rd gear.

- If the thickness is within the service limit, replace the 3rd/4th synchro hub and the 3rd/4th synchro sleeve as a set.

Standard: 23.92-23.97 mm (0.942-0.944 in)

Service Limit: 23.80 mm (0.937 in)

4. Measure the clearance between 4th gear ( A ) and the 4th/5th gear distance collar ( B ) with a dial indicator (C).

- If the clearance exceeds the service limit, go to step 5.

e If the clearance is within the service limit, go to step 7.

Standard: 0.06-”0.16 mm (0.002-0.006 in)

Service Limit: 0.25 mm (0.010 in)

5. Measure the length of the
4th/5th gear distance collar as shown.

- If the length is not within the
standard, replace the 4th/5th gear distance collar, - If the length
is within the standard, go to step 6.

Standard: 24.03-24.08 mm (0.946-0.948 in)

6. Measure the thickness of 4th gear, - If the thickness is less than the service limit, replace 4th gear.

- Sf the thickness is within the service limit, replace the 3rd/4th synchro hub and the 3rd/4th synchro sleeve as a set.

Standard: 23.92-23.97 mm (0.942-0.944 in)

Service Limit: 23.80 mm (0.937 in)

7. Measure the clearance between the 4th/5th gear distance collar (A) and 5th gear (B) with a dial indicator (C).

- If the clearance exceeds the service limit, go to step 8.

- If the clearance is within the service limit, go to step 10.

Standard: 0.06-0.16 mm (0.002-0.006 in)

Service Limit: 0.25 mm (0.010 in)

8. Measure the length of the
4th/5th gear distance collar as shown.

- If the length is not within the
standard, replace the 4th/5th gear distance collar.

- If the length is within the
standard, go to step 9.

Standard: 24.03-24.08 mm (0.946-0.948 in)

9. Measure the thickness of 5th gear.

- If the thickness is less than the service limit, replace 5th gear.

- If the thickness is within the service limit, replace the 5th synchro hub and 5th synchro sleeve as a set.

Standard: 23.92-23.97 mm (0.942-0.944 in)

Service Limit: 23.80 mm (0.937 in)

10. Measure the length of the MBS distance collar. If the length is not within standard, replace the MBS distance collar.

Standard: 23.95-24.05 mm (0.943-0.947 in)
