Assembly
1. Carry out these steps before reassembling:
^ Inspect the gears for broken or cracked teeth. Check for unusual wear patterns.
^ Inspect the thrust washers for face wear, cracks, scoring and for signs of heat damage.
^ Inspect the bearings, bearing cups and the synchronizers for wear or damage.
^ Inspect the output shaft for scoring or worn or damaged splines. Install new components as necessary.
^ Always install new retaining rings.
2. Lubricate all components with the recommended transmission fluid when reassembling.
3. NOTE: Position the output shaft with the output end facing upward.
NOTE: Install the synchronizer assembly with the deeper center flange of the synchronizer hub facing toward the rear of the output shaft.
Install the 1st/2nd synchronizer assembly on the output shaft, then install a new retaining ring.
^ If installing the original synchronizer assembly, make sure the index marks made during disassembly are aligned.
^ It may be necessary to press the hub into position on the shaft.
^ Do not overextend the retaining ring. A damaged or overextended retaining ring will not allow 1st gear to fully seat.
4. Install the 1st gear synchronizer blocking ring.
^ Align the blocking ring tabs with the synchronizer assembly.
5. Install the outer 1st gear synchronizer cone.
6. Install the inner 1st gear synchronizer cone. Rotate the inner cone till it is seated.
7. Install the 1st gear needle bearing.
^ Apply petroleum jelly to the bearing.
8. Install 1st gear.
^ First gear is 127 mm (5 inch) in diameter.
^ Rotate the gear to align the gear slots with the inner cone tabs.
^ Make sure that the gear fits over the retaining ring.
9. Install the reverse synchronizer cone.
10. Install the reverse gear blocking ring.
11. Using the special tools, install the reverse gear bearing spacer.
12. Install the reverse gear needle bearing.
^ Apply petroleum jelly to the bearing.
13. Install the reverse gear synchronizer assembly.
14. Install reverse gear.
^ Rotate the gear to align the gear slots with the inner cone tabs.
^ Make sure the clutching teeth on the gear snap inside the sliding sleeve and the sliding sleeve is against the gear.
^ Function the synchronizer sleeve through the 2 positions to make sure of normal function.
15. Install the check ball.
^ Use petroleum jelly to hold the check ball in place.
16. Install the thrust washer. Be sure to align the slot in the washer with the check ball.
17. Install the rear output shaft bearing, then 5th gear. Using the special tool, press both the bearing and gear into place.
^ The flat side of 5th gear faces the output shaft end.
18. Install a new retaining ring.
^ Do not overextend the retaining ring.
19. Reposition the output shaft with the input end facing upward.
20. Install the 2nd gear synchronizer blocking ring. Rotate the blocking ring until seated.
21. Install the 2nd gear synchronizer outer cone and the second gear synchronizer inner cone.
22. Install the 2nd gear bearing.
^ Apply petroleum jelly to the bearing.
23. Install 2nd gear.
^ Rotate the gear to align the gear slots with the inner cone tabs.
