Procedure -

1. Coat the thrust bearing with transmission lube and install the thrust bearing, beveled washer (flat side toward bearing), and snap ring on the input shaft.

2. Assemble pump piston into input shaft with light coating of transmission lube.

3. Install the input shaft into the main drive gear and install the splined washer.

4. Install the snap ring.

Note: Old style splined washers have two different sides. The flat side must face the snap ring.

5. Install the concentric pump over the pump piston and install the input bearing using a bearing heater or arbor press.

6. Install a new input shaft seal and bearing race in the front bearing cover (Tool ref. ID T10) using an arbor press as shown.

7. Apply transmission lube to the input bearing and install the front bearing cover.

8. Line the hole in the bearing cover up with the threaded hole in the eccentric pump.

9. Install the set screw into the bearing cover using a 5/64" allen wrench and tighten to 3 lb-ft (4 Nm). This will retain the bearing cover on the input shaft assembly.

10.Proceed to the mainshaft shimming procedure to complete the installation of the input shaft and bearing cover assembly.
