Clearance Inspection

1. Assemble the bearings, synchro hub, synchro sleeve, gears, spacer collar, etc. on the mainshaft as instructed above.




2. Measure the clearance: support the bearing race with a socket, push down on the shaft and measure the clearance between 3rd and 2nd gears.




3. If the reading is outside specification, measure the thickness of 3rd gear.
4. If the reading is within specifications, replace the synchro hub.
5. If the service limit is exceeded, replace the gear.




6. Measure the clearance between 4th gear and the spacer collar.




7. If the reading is out of specification, measure distance (A) on the spacer collar.




8. If distance (A) is within specification, measure the thickness of 4th gear.
- Replace 4th gear if its measurement is out of specification.
- Replace 4th gear synchro hub if 4th gear is within specification.




9. Measure the clearance between 5th gear and the spacer collar.




10. If the reading is out of specification, measure distance (B) on the spacer collar.




11. If distance (B) is within specification, measure the thickness of 5th gear.
- Replace 5th gear if its measurement is out of specification.
- Replace 5th gear synchro hub if 5th gear is within specification.
