How to Install the Countershaft Assemblies (w/Ball Bearings) A Series

Special Instructions

For ease of assembly, mount the auxiliary section in a vise.

When Installing the countershaft assemblies into the countershaft bearings, keep the countershaft assemblies straight. Do not cock the countershafts.

If, when the countershaft bearing cover is removed and you can not see the snap ring groove, install the cover and drive the countershaft further until you can see the groove.

Special Tools

• Typical Service Tools • Vise with brass jaws or wood blocks • Bearing driver and a maul • Toolmaker’s dye • Large snap ring pliers

Procedure -

1. Place the countershaft assembly vertical on a clean, flat surface. If previously removed, using the proper driver and maul install the countershaft bearing race.

2. In the countershaft rear bearing bore, using the proper driver and maul, install the countershaft bearing.

3. Temporarily install the rear bearing cover, use two (2) capscrews and no gasket. The cover holds the bearing as the countershaft is driven into the bearing.

4. Use toolmaker’s dye and mark the smaller LO range gear tooth that aligns with countershaft gear marked with an “O”.

5. Position the countershaft in the auxiliary housing. Mesh the countershaft marked tooth with either set of LO range gear marked teeth.

6. Use a sort bar and maul and drive the countershaft into the countershaft bearing.

7. From the auxiliary housing rear, remove the countershaft bearing cover and install the rear countershaft snap ring in the snap ring groove.

8. Position a new gasket on the countershaft bearing cover mounting surface.

9. Position the countershaft bearing cover over the gasket.

10.Apply Eaton/Fuller sealant #71205 or equivalent to the retaining capscrews.

11.Install the capscrews, tighten to 35-45 lb-ft of torque.

12.Repeat all steps for other countershaft installation.

Final Check

• Check both countershafts for timing; the output shaft should rotate freely. • Check capscrews for proper torque.
