Mainshaft: Testing and Inspection

CLEARANCE MEASUREMENTS

NOTE: Lubricate all parts with ATF during assembly.

1. Remove the mainshaft bearing from the transmission housing.





2. Assemble the parts below on the mainshaft.

NOTE: Do not install the O-rings during inspection.





3. Torque the mainshaft locknut to 29 Nm (22 ft. lbs.).

NOTE: Mainshaft locknut has left-hand threads.

4. Move the 4th/2nd clutch assembly to check the axial clearances.





5. Attach the dial indicator to the mainshaft 2nd gear as shown.





6. Measure the 2nd gear axial clearance while pushing the 4th/2nd clutch toward the 1st clutch.
* STANDARD: 0.07 - 0.15 mm (0.003 - 0.006 inch).

NOTE: Take measurements in at least three places, and use the average as the actual clearance.

7. If the clearance is out of tolerance, remove the 2nd gear thrust washer and measure its thickness.





8. Select and install a new 2nd gear thrust washer, then recheck.
9. After replacing the 2nd gear thrust washer, make sure that the clearance is within tolerance.





SUB-ASSEMBLY

NOTE:
* Lubricate all parts with ATF during assembly.
* Before installing the O-rings, wrap the shaft splices with tape to prevent damage to the O-rings.
* Assemble the mainshaft sub-assembly when assembling the transmission.

1. Assemble the parts below on the mainshaft.
