#### Mainshaft Assembly Clearance Inspection

13-24

NOTE: If replacement is required, always replace the synchro sleeve and hub as a set.

1. Support the bearing inner race with a socket (A) and push down on the mainshaft (B).

Standard: | 0.06 – 0.21 mm (0.002 – 0.008 in.)
Service Limit: | 0.3 mm (0.1 in.)

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

- If the clearance is more than the service limit, go to step 3.
- If the clearance is within the service limit, go to step 4.

3. Measure the thickness of 3rd gear

- 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.

Standard: | 27.92 – 27.97 mm (1.099 – 1.101 in.)
Service Limit: | 27.85 mm (1.096 in.)

4. Measure the clearance between 4th gear (A) and the spacer collar (B) with a dial indicator (C). If the clearance is more than the service limit, go to step 5.

Standard: | 0.-06 – 0.19 mm (0.002 – 0.007 in.)
Service Limit: | 0.3 mm (0.01 in.)

5. Measure the distance on the spacer collar.

- If distance is less than the standard, replace the spacer collar with a new one.
- If distance is within the standard, go to step 6.

Standard: | 24.03 – 24.06 mm (0.946 – 0.947 in.)
