Note: The yokes and the universal joints must be in-phase, as shown.

1. Measure thickness (2) of retainer (3) near the off positioned hole.

2. Install bearings (1) into cage (5). The word "thrust" has been engraved on the bearing race of the inside diameter of both of the bearings. Make sure that the bearings are assembled so that the words "thrust" are adjacent.

3. Install retainer (3) without shims (6).

4. Install four of the twelve bolts (7) in the retainer. Equally space the bolts. Evenly tighten the bolts to 55 ± 10 N·m (40 ± 8 lb ft).

5. Measure the distance from the surface of retainer (3) to the surface of cage (5). Use a depth micrometer in order to make the measurement. Make the measurement through the off positioned hole.

6. Subtract the measurement on Step 5 from the measurement on Step 1. The difference in the measurements is the required thickness of the shims (6). The shim pack must be within 0.025 mm (.0010 inch) of the required thickness.

7. Remove the four bolts (7) and retainer (3).

8. Install O-ring (4), required shims (6), and retainer (3). Install 12 bolts (7). Tighten the 12 bolts evenly to 55 ± 10 N·m (40± 8 lb ft).
