5th/6th Gear

5th/6th Gear

1. Inspect the 5th and 6th gear synchronizer cones, gear teeth and rings for wear or damage. Replace as necessary.

2. NOTE: Set the synchronizer ring squarely on the gear and measure around the circumference.
Using a feeler gauge, while applying pressure and rotating the synchronizer ring, measure the clearance between the 5th gear synchronizer ring and the flank surface of the gear. The measurement should be the same around the entire circumference. Replace the synchronizer ring if less than the minimum specification.

4. Measure the clearance between the clutch hub sleeve and the shift fork. Replace if it exceeds the maximum specification.
- Inspect the clutch hub sleeve and clutch hub operation. Replace if there is a malfunction.

5. Using a telescoping gauge, measure the ID of the 5th gear. Using a micrometer, measure the OD of the gear sleeve.





6. Measure the telescoping gauge to determine if the gear to the gear sleeve clearances are within specifications. If not within specifications, replace as needed.





7. Using a telescoping gauge, measure the ID of the 6th gear. Using a micrometer, measure the OD of the gear sleeve.





8. Measure the telescoping gauge to determine if the gear to the gear sleeve clearances are within specifications. If not within specifications, replace as needed.
