1. Remove the tapered bearing from the input shaft. Use the J 22912-O1 and a hydraulic press.



2. Remove the bearing race from the input shaft . Use the J 23907 and the J 39594 .

Tools Required

1. Remove the following parts:

1.1.	The mainshaft large tapered bearing and the O-ring seal

1.2.	The 1ST speed gear

1.3.	The 1ST speed gear caged needle bearing




2. Remove the following parts:

2.1.	The retainer ring

2.2.	The 1ST speed gear blocking ring assembly

2.3.	The thrust washer

2.4.	The inner cone

2.5.	The friction cone

2.6.	The blocking ring

Important: The synchronizer hubs and sliding sleeves are a selected assembly. Keep these parts together as originally assembled.




3. Scribe a mark on the synchronizer hub and on the sleeve. This will help you to reinstall the parts in the same position.



4. Remove the 2ND speed gear (The lST/2ND speed synchronizer assembly, the 2ND speed gear blocking ring, the friction cone, the 2ND speed gear inner cone, and the thrust washer will press off with the 2ND speed gear). Use the J 36513 and a hydraulic press



5. Remove the 2ND speed gear caged needle bearing.



6. Remove the 3RD/4TH speed synchronizer retainer ring.

Important: The synchronizer hubs and sliding sleeves are a selected assembly. Keep these parts together as originally assembled.




7. Scribe a mark on the synchronizer hub and on the sleeve. This will help you to reinstall the parts in the same position.



8. Remove the 3RD speed gear (The 3RD/4TH speed synchronizer assembly and the 3RD speed gear blocking ring will press off with the 3RD speed gear). Use the J 39473 , V-blocks, and a hydraulic press.



9. Remove the spacer and the 3RD speed gear caged needle bearing.

Important: Do not replace the tapered bearing unless inspection shows bearing damage.




10. Remove the mainshaft small tapered bearing. Use the J 39442 , and the J 39443 , and a hydraulic press.
