4. Install the synchronizer ring set No.1 to 1st gear.
NOTE:
Apply the gear oil sufficiently on the sliding surface.





5. As shown in the illustration, set the synchronizer hub and synchronizer sleeve.
NOTE:

- Apply gear oil to the caulked area between the sleeve and the hub.
- After installation, confirm the sleeve and the hub slide smoothly.





6.
CAUTION:

- Pay attention to the direction of inserting the synchronizer hub and synchronizer sleeve.
- During press fit, confirm correct positions of the hub and the synchronizer ring.
- Check for smooth rotation of the gear after installation.
- The synchronizer ring must not bind.

Install the synchronizer hub and synchronizer sleeve to the output shaft No.1 in the direction as shown in the illustration.





7. Using special tools MD998812, MD998814 and MD998824, install the synchronizer hub and synchronizer sleeve.
NOTE:

10. Insert the 2nd gear and needle roller bearing to the output shaft No.1.





11. Fit the ball into groove as shown in the illustration.





12. Select a shaft snap ring that allows distance of the thrust crevice of 2nd gear bearing inner race to fall within the standard value range.
Standard value: 0 - 0.1 mm (0 - 0.0039 inch)






13. Install the snap ring.





14. Insert the spacer to the output shaft No.1.





15. Insert the needle roller bearing to the output shaft No.1.





16. Insert the 4th gear sub-assembly and synchronizer ring set No.4 to the output shaft No.1.
