Output Shaft

DISASSEMBLY
1. Remove input shaft and output shaft pilot bearing rollers from output shaft.

10. Remove select fit snap-ring holding the 3-4 synchronizer onto the output shaft.

Fig. 107:

11. Using Bearing Splitter P-334 or suitable press plates positioned under third gear, press the 3-4 synchronizer and third gear from output shaft.
12. Remove third gear needle roller bearing from output shaft or gear.

ASSEMBLY
1. Lubricate transmission components with specified gear lubricant.

2. If necessary, assemble 1-2 and 3-4 synchronizer hubs, sleeves, springs and key inserts.
3. Install third gear needle bearing onto the output at shaft.
4. Install third gear over bearing and onto output shaft flange.
5. Install third gear synchronizer ring to third gear.
6. Position the 3-4 synchronizer onto the output shaft.
7. Using Adapter 6747-1A and a shop press, press the 3-4 synchronizer onto the output shaft.

8. Select the thickest snap-ring that will fit into the snap-ring groove of the output shaft.
9. Install snap-ring to hold 3-4 synchronizer onto output shaft.

Fig. 110:

10. Verify third gear thrust clearance with feeler gauge. Clearance should be 0.10 - 0.25 mm (0.004 - 0.010 inch). If clearance is out of specification, refer to Cleaning and Inspection.
11. Install second gear needle bearing onto output shaft.
12. Install second gear over bearing and onto output shaft flange.
13. Install second gear synchronizer ring onto second gear.
14. Position 1-2 synchronizer assembly onto splines of output shaft.
15. Using Driver MD-998805, Adapter 6747-1A, and a shop press, press the 1-2 synchronizer onto the output shaft.
16. Install first gear synchronizer ring into 1-2 synchronizer.

Fig. 111:

17. Install first gear bearing inner race lock ball in output shaft.

Fig. 112:

18. Install first gear needle bearing onto output shaft.
19. Install first gear onto output shaft and over bearing.
20. Install first gear bearing inner race onto output shaft and inside first gear bearing. Rotate bearing race until race installs over lock ball.
21. Position output shaft rear bearing onto output shaft. Ensure that the snap ring groove in bearing outer race is toward rear of output shaft.
22. Using Driver L-4507 and suitable mallet, drive bearing onto output shaft.
23. Install snap-ring onto output shaft rear bearing outer race.

Fig. 113:

24. Check first-second gear thrust clearance. Standard clearance is 0.10 - 0.25 mm (0.004 -0.010 inch). If clearance is out of specification, refer to Cleaning and Inspection.
25. Position fifth gear onto output shaft with the gear's short shoulder toward the rear of shaft. Ensure that the gear and output shaft splines are aligned.
26. Using Adapter 6747-1A, Driver L-4507, and a shop press, press fifth gear onto output shaft.
