NOTE: Before the top shaft is installed in the housing be sure the front retainers are tight and the rear retainers are loose. This will permit the top shaft to be lowered in position correctly.

1. Use a hoist and sling as a support and put the top shaft in the housing.

2. With the hoist and sling connected, install the bearing caps (2) with bolts (3). This will make sure that all of the top shaft bearings (1) are installed correctly.

3. Tighten the rear retainers (4).

4. Connect all tube assemblies (5) to the top shaft.

5. Lower the top cover (6) on the housing. Make an alignment of the holes in the cover with the holes in the housing.
