Mainshaft Assembly Clearance Inspection

Mainshaft Assembly Clearance Inspection





NOTE:
^ If replacement is required, always replace the synchro sleeve and hub as a set.
^ Support the bearing inner race, and push down on the mainshaft as shown.





1. Measure the clearance between 3rd gear (A) and the ball bearing (B) with a feeler gauge.
^ If the clearance is more than the service limit, go to step 2.
^ If the clearance is within the service limit, go to step 4.





2. Measure the distance of the distance collar.
^ If distance is not within the standard, replace the distance collar.
^ If distance is within the standard, go to step 3.








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.





4. Measure the clearance between 4th gear (A) and distance collar (B). If the clearance is more than the service limit, go to step 5.





5. Measure distance 1 on the distance collar.
^ If distance 1 is not within the standard, replace the distance collar.
^ If distance 1 is within the standard, go to step 6.








6. Measure the thickness of 4th gear.
^ If the thickness is less than service limit, replace 4th gear.
^ If the thickness is within the service limit, replace the 3rd/4th synchro hub.





7. Measure the clearance between 5th gear (A) and the distance collar (B). If the clearance is more than the service limit, go to step 8.





8. Measure distance 2 on the distance collar.
^ If distance 2 is not within the standard, replace the distance collar.
^ If distance 2 is within the standard, go to step 9.





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/6th synchro hub.





10. Measure the clearance between 6th gear (A) and the mainshaft (B). If the clearance is more than the service limit, go to step 11.





11. Measure the thickness of 6th gear.
^ If the thickness is less than the service limit, replace 6th gear.
^ If the thickness is within the service limit, replace the 5th/6th synchro hub.
