Special Tools

Important: The shimming procedure is required to be performed during service only when the following parts are replaced:

Input Shaft, Mainshaft, and Countershaft

1. Rotate the transmission adapter plate to the vertical position.
2. Install the following assemblies in order:

2.1.	The input shaft to the adapter plate

2.2.	Align the 4th speed gear blocking ring to the input shaft.

2.3.	The mainshaft assembly

2.4.	The countershaft (lift up the mainshaft enough to install the countershaft.)




3. Install the transmission case.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the adapter plate to transmission case bolts.

Tighten
Tighten the bolts to 36 N·m (27 Ib ft).




5. Measure the input shaft/mainshaft end play using the following procedure:

5.1.	Place the tip of the J 8001 -3 on the end of the mainshaft.

5.2.	Move the main shaft up and down.

5.3.	Record the measurement.

6. Select a shim to achieve 0.0127-0.0889 mm (0.00049-0.00349 in) preload.
7. Remove the J 8001 -3.



8. Measure the countershaft end play using the following procedure:

8.1.	Place the tip of the J 8001 -3 on the end of the countershaft.

8.2.	Move the countershaft up and down.

8.3.	Record the measurement.

9. Select a shim to achieve 0.0127-0.0889 mm (0.00049-0.00349 in) preload.
10. Remove the J 8001 -3.



11. Remove the shift lever guide bolts.



12. Remove the adapter plate to the transmission case bolts.



13. Remove the transmission case.



14. Remove the following parts in order:

14.1.

The countershaft (lift up the mainshaft enough to remove the countershaft).

14.2.

The mainshaft assembly

14.3.

The input shaft from the adapter plate




15. Remove the input shaft bearing race.
16. Remove the input shaft bearing shim and discard.
17. Install the new input shaft bearing shim, and the original bearing race.



18. Remove the countershaft bearing race.
19. Remove the countershaft bearing shim and discard.
20. Install the new input shaft bearing shim, and the original bearing race.
21. Refer to Transmission Assemble.
