Disassembly/Inspection/Reassembly

NOTE:
- Lubricate all parts with ATF during reassembly.
- Inspect the thrust needle bearings and the needle bearings for galling and rough movement.
- Before installing the O-rings, wrap the shaft splines with tape to prevent damage to the O-rings.
- The locknut has left-hand threads.

Inspection
Clearance Measurements





1. Assemble the parts on the countershaft.

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





2. Torque the countershaft locknut to 29 Nm (3.0 kgf-m, 22 ft. lbs.).

NOTE: Countershaft locknut has left-hand threads.








3. Hold the 1st-hold clutch assembly against the park gear. Measure the clearance between the 1st-hold clutch distance collar and the 1st-hold clutch with a feeler gauge.

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

4. If the clearance is out of tolerance, remove the 1st-hold clutch distance collar and measure its length.
5. Select and install a new 1st-hold clutch distance collar, then recheck the clearance.





1ST-HOLD CLUTCH DISTANCE COLLAR

6. After replacing the 1st-hold clutch distance collar, make sure that the clearance is within tolerance.





7. Attach a dial indicator to the side of the 2nd gear.





8. Measure 2nd gear axial clearance while pushing the 1st gear towards the reverse clutch assembly.

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

9. If the clearance is out of tolerance, remove the 45.5 x 60 mm thrust washer, and measure its thickness.

1. Select and install a new 45.5 x 60 mm thrust washer, then recheck the clearance.





THRUST WASHER, 45.5 X 60 MM

11. After replacing the 45.5 x 60 mm 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 splines with tape to prevent damage to the O-rings.
- Assemble the countershaft sub-assembly when assembling the transmission.

Assembly the parts on the countershaft.
