Adjustment

1. M/T Differential Thrust Clearance Adjustment





1. Remove the oil seal (A).

NOTE: Be careful not to damage the transmission housing while removing the oil seal.





2. If you removed the 80 mm shim (A) from the transmission housing, reinstall the same sized shim.





3. Install the differential assembly (A).





4. Install the transmission housing onto the clutch housing.

NOTE: Tighten the 8 mm flange bolts in a crisscross pattern in several steps.












5. Use the 40 mm I.D. driver handle to bottom the differential assembly in the clutch housing.





6. Measure the clearance between 80 mm shim and the bearing outer race in the transmission housing.







7. If the clearance exceeds the standard, select a new 80 mm shim from the following table. If the clearance measured in step 6 is within the standard, go to step 10.







8. Remove the transmission housing.

9. Replace the thrust shim with the correct one selected in step 7, then recheck the clearance.





10. Install a new oil seal flush with the transmission housing using the 65 mm oil seal driver.

Installation

1. Differential Assembly





1. Install the magnet (A).

NOTE: Clean the magnet any time the transmission is disassembled.

2. Install the differential assembly (B).

5. M/T Reverse Shift Fork





1. Install the reverse shift fork (A).

6. M/T Transmission Housing Assembly





1. Clean any dirt or oil from the mating surface of the transmission housing and the clutch housing.

2. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, 08718-0004, or 08718-0009 evenly to the clutch housing mating surface of the transmission housing. Install the component within 5 minutes of applying the liquid gasket.

NOTE:
* If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.





3. Install the 14 x 20 mm dowel pins (A).

4. Set the tapered cone ring pawl (B) faces the 5th shift fork (C).

5. Place the transmission housing on the clutch housing, making sure to line up the shafts.

6. While expanding the 69 mm snap ring (D) on the countershaft ball bearing using snap ring pliers, push the transmission housing down to start the countershaft ball bearing through the snap ring.

7. Release the pliers, and push down the housing until it bottoms out and the snap ring snaps in place in the countershaft ball bearing snap ring groove.

NOTE: Install the 32 mm sealing cap (E) after setting in the 69 mm snap ring.





8. Make sure the 69 mm snap ring (A) is securely seated in the groove of the countershaft bearing.

Dimension (1) as installed: 3.3-6.5 mm (0.130-0.256 in)

9. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, 08718-0004, or 08718-0009 evenly to the threads of the 32 mm sealing cap. Install the component within 5 minutes of applying the liquid gasket.

NOTE:
* If you apply liquid gasket P/N 08718-0012, the component must be installed within 4 minutes.
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.
