Special Instructions

The following instructions are used to remove the upper and lower countershaft bearings. To remove the mainshaft assembly, only the upper countershaft bearings need to be removed.

Special Tools

• Typical Service Tools • Soft bar and a maul • Bearing puller or pry bars

Procedure -

1. To keep the mainshaft pilot from falling out of the input shaft pocket, temporarily install the auxiliary drive gear on the mainshaft.

2. From each countershaft rear groove, remove the snap ring.

3. From inside the case, use a soft bar and maul to drive the countershaft rear bearings from the case bores.

4. From the front of each countershaft, remove the capscrew and front retainer plate.

5. Use the soft bar and maul to drive each countershaft to the rear as far as possible. This partially unseats the front bearings.

6. Return to the case rear, and drive each countershaft forward as far as possible. This exposes the bearing snap rings.

7. Use a bearing puller or pry bars to remove the countershaft front bearings. If a bearing puller is used, the front bearing cover has to be removed.
