Mainshaft Assembly

Assemble (Figures 41 through 45)

Tools Required:
Hydraulic Press
J 36183 Input Shaft Press Tube with Cap
J 36184 Adapter Press Tube Reducer
J 36513 Gear and Bearing Separator Plate
J 22912-01 Separator Plate or Equivalent

Important
^ The assembly of some components will require use of an assembly lube. It is recommended that TRANSJEL(TM) J 36850 or equivalent be used during assembly.

^ Heat the 2WD speed sensor rotor (45) for 7-10 minutes at 120~C (250~F) prior to installation during assembly procedures.





1. Bearing assembly (17) and reverse speed gear (25) (figure 41).
2. When pressing the fifth-reverse synchronizer assembly (26):

A. Manually align and engage splines.
B. Press until seated.
C. Be sure all shavings are removed.

3. Fifth-reverse synchronizer assembly (26) with synchronizer ring (2) using J 36183, J 36184, J 36513, and hydraulic press.

^ Check scribe marks for correct positions. Position spiral lock ring (27) towards reverse speed gear (25).

4. NEW snap ring (29).





5. Bearing assembly (30) and fifth speed gear (31) (figure 42).





6. Bearing assembly (17) and first speed gear (22) (figure 43).

7. When pressing the first-second synchronizer assembly (19):

A. Manually align and engage splines.
B. Start press operation, STOP before tangs engage.
C. Lift and rotate gear (22) to engage synchronizer ring (2).
D. Continue to press until seated.
E. Be sure all shavings are removed.

8. First-second synchronizer assembly (19) with both synchronizer rings (2) using J 36183, J 36184, J 22912-01, and hydraulic press.

^ Check scribe marks for correct positions.

Important
^ The groove on the outside of the sleeve MUST GO TOWARDS THE SECOND SPEED GEAR to prevent gear clash during first and second gear shifts. The teeth of the sleeve have different angles.





9. Bearing assembly (17) and second speed gear (18) (figure 44).

^ Make sure bearing cage is together.

10. Spacers (16) and collar (15).





11. Bearing assembly (14) and third speed gear (13) (figure 45).
12. When pressing the third-fourth synchronizer assembly (7):

A. Manually align and engage splines.
B. Start press operation, STOP before tangs engage.
C. Lift and rotate gear (13), to engage synchronizer ring (2).
D. Continue to press until seated.
E. Be sure all shavings are removed.

13. Third-fourth synchronizer assembly (7) with both synchronizer rings (2) using J 36183, J 36184, J 22912-01, and hydraulic press.

14. NEW snap ring (6).
