M/T Mainshaft Thrust Clearance Adjustment

M/T Mainshaft Thrust Clearance Adjustment

Special Tools Required

- Catch adapter 07GAJ-PG20110
- Base adapter 07GAJ-PG20130
1. Install the mainshaft assembly in the clutch housing.

2. Install oil guide plate M and the 82 mm shim(s) (A) into the transmission housing.

3. Install the transmission housing onto the clutch housing, then tighten the 8 mm flange bolts in a crisscross pattern in several steps.










4. Attach the catch adapter (A) and the base adapter (B) to the mainshaft as follows:
- Backout the catch adapter bolt (C), and loosen the two hex bolts (D).

- Fit the catch adapter over the mainshaft so its lip is towards the transmission.

- Align the catch adapter lip around the groove at the inside of the mainshaft splines, then tighten the hex bolts.

5. Fully seat the mainshaft by tapping its end using a plastic hammer.

6. Thread the catch adapter bolt in until it just contacts the wide surface of the base adapter.






7. Zero a dial gauge (A) on the end of the mainshaft.

8. Turn the catch adapter bolt (B) clockwise; stop turning when the dial gauge has reached its maximum movement. The reading on the dial gauge is the amount of mainshaft end play.
NOTE: Do not turn the catch adapter bolt more than 60 degrees after the needle of the dial gauge stops moving. Applying more pressure with the catch adapter bolt may damage the transmission.

9. If the reading is within the standard, the clearance is correct. If the reading is not within the standard, select the appropriate shim needed from the table, and recheck the shim thickness.
Standard: 0.14-0.21 mm (0.006-0.008 in.)
