2. 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 and sleeve.





4. Measure the clearance between 4th gear (A) and the distance collar (B) with a feeler gauge.
^ If the clearance is more than the service limit, go to step 5.
^ If the clearance is within the service limit, go to step 7.





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 and sleeve.





7. Measure the clearance between 5th gear (A) and the distance collar (B) with a dial indicator.
^ If the clearance is more than the service limit, go to step 8.
^ If the clearance is within the service limit, go to step 10.





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 and sleeve.





10. Measure the clearance between 6th gear (A) and the mainshaft (B) with a dial indicator. 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 and sleeve.
