(3) Shim pack

(4) Gap

(5) Cage

(6) O-ring seal

(7) Bolt

  1. Prior to assembly of the components use 0.038 mm (0.0015 inch) shim stock or a standard feeler gauge to check the following:

    1. Ensure that the bearing cups are seated in the case assembly and the cage assembly.

    1. Ensure that the bearing cones are seated on the transfer gear.

  1. Prior to assembly, lubricate the bearing cups and the bearing cones with the lubricant that is being sealed.

  1. Position the case assembly (1) horizontally.

  1. Assemble transfer gear (2), bearings and cage assembly (5) without shims (3) or O-ring seal (6) .

  1. Tighten 12 bolts (7) evenly.

  1. Rotate transfer gear (2) at least three revolutions to seat the bearings.

  1. Measure gap (4) between cage assembly (5) and the case assembly (1) .

  1. Add shims (3) to obtain a 0.10 ± 0.05 mm (0.004 ± 0.002 inch) endplay.

  1. Remove 12 bolts (7). Remove cages assembly (5) .

  1. Install the required shims (3) .

  1. Lubricate O-ring seal (6) lightly with the lubricant that is being sealed.

  1. Install O-ring seal (6) to cage assembly (5) .

  1. Install cage assembly (5) and 12 bolts (7) .

  1. Measure end play of transfer gear (2). The end play of the transfer gear must be 0.10 ± 0.05 mm (0.004 ± 0.002 inch).

  1. If end play is less than 0.10 ± 0.05 mm (0.004 ± 0.002 inch), add shims. If end play is greater than 0.10 ± 0.05 mm (0.004 ± 0.002 inch), remove shims.
