Outer diameter

If the outer diameter is less than the minimum, replace the input shaft.





13. INSPECT 4TH GEAR
a. Using a cylinder gauge, measure the inside diameter of the 4th gear.





Inside diameter

If the inside diameter is exceeds the maximum, replace the 4th gear.





14. INSPECT 3RD GEAR
a. Using a cylinder gauge, measure the inside diameter of the 3rd gear.





Inside diameter

If the inside diameter is exceeds the maximum, replace the 3rd gear.





15. INSPECT 4TH GEAR SYNCHRONIZER RING
a. Coat the 4th gear cone with gear oil. Turn the synchronizer ring in one direction while pushing it against the 4th gear cone. Check that the ring locks.
If the synchronizer ring does not lock, replace the ring or 4th gear.





b. Using a feeler gauge, measure the clearance between the 4th gear synchronizer ring back and 4th gear spline end.
Standard clearance: 0.75 to 1.65 mm (0.0295 to 0.0650 inch)
If the clearance is out of specification, replace the 4th gear synchronizer ring.





16. INSPECT 3RD GEAR SYNCHRONIZER RING
a. Coat the 3rd gear cone with gear oil. Turn the synchronizer ring in one direction while pushing it against the 3rd gear cone. Check that the ring locks.
If the synchronizer ring does not lock, replace the ring or 3rd gear.





b. Using a feeler gauge, measure the clearance between the 3rd gear synchronizer ring back and 3rd gear spline end.
Standard clearance: 0.65 to 1.75 mm (0.0256 to 0.0689 inch)
If the clearance is out of specification, replace the 3rd gear synchronizer ring.





17. INSPECT TRANSMISSION HUB SLEEVE NO.2
a. Check the sliding condition between the transmission hub No.2 and transmission hub sleeve No.2.
b. Check that the spline gear edges of the transmission hub sleeve No.2 is not worn down.
