Countershaft Reassembly

Countershaft:

Special Tools Required
^ Driver handle 07746-0030100
^ Attachment, 30 mm I.D. 07746-0030300

NOTE: Refer to the Exploded View, as needed, during this procedure.

1. Clean all parts in solvent, dry them, and apply MTF to all contact surfaces.
2. Install the distance collar, needle bearing, and 1st gear onto the countershaft.
3. Install the triple cone synchro assembly (A) by aligning the synchro cone fingers (B) with the grooves in 1st gear (C), then install the synchro spring (D).





4. Install the 1st/2nd synchro hub (A) by aligning the synchro ring fingers (B) with the grooves in the 1st/2nd synchro hub (C).





5. Install the reverse gear.
6. Install the synchro spring (A).





7. Install the triple cone synchro assembly (B) by aligning the synchro ring fingers (C) with the grooves in the 1st/2nd synchro hub (D).
8. Install the distance collar (A) and friction damper (B) by aligning the friction damper fingers (C) with the grooves in the 1st/2nd synchro hub (D).





9. Install the needle bearing.
10. Install 2nd gear (A) by aligning the synchro cone fingers (B) with the grooves in 2nd gear (C).





11. Support the countershaft (A) on steel blocks, then install 3rd gear (B) using the 40 mm I.D. driver (C) and a press (D).

NOTE: Do not exceed the maximum pressure.





12. Install 4th gear (A) using the 40 mm I.D. driver (B) and a press (C).

NOTE: Do not exceed the maximum pressure.





13. Install 5th gear (A) using the 40 mm I.D. driver (B) and a press (C).

NOTE: Do not exceed the maximum pressure.





14. Install the distance collar (A), 35 mm shim, and old ball bearing (B) using the 40 mm I.D. driver (C), 30 mm I.D. attachment (D), and a press (E).





15. Measure the clearance between the old bearing (A) and the 35 mm shim (B) with a feeler gauge (C).





16. If the clearance is more than the standard, select a new shim from the following table. If the clearance measured in step 15 is within the standard, replace only the ball bearing.





17. Support the ball bearing (A) on steel blocks (B), then use a press (C) and an attachment (D) to press the countershaft (E) out of the ball bearing.





18. If necessary, install the 35 mm shim selected in step 16.
19. Install the distance collar (A), 35 mm shim, and new ball bearing (B) using the 40 mm I.D. driver (C), 30 mm I.D. attachment (D), and a press (E), then recheck the clearance.





20. Securely clamp the countershaft assembly in a bench vise with wood blocks (A).





21. Apply manual transmission fluid (MTF) to the new special bolt (B), then tighten it (left-hand threads).
