(1) Lightly lubricate the sealing lip of the lip type seal with the lubricant that is being sealed.

(2) Tighten two opposite bolts to an equal torque. Tighten the remaining two bolts to an equal torque. Repeat the procedure until all bolts are at the proper torque.

(3) Bolts

Use the following procedure to install bolts (3) .

  1. Install three equally spaced bolts (3) .

  1. Tighten three bolts to a preliminary torque of 47 ± 7 N·m (35 ± 5 lb ft).

  1. Ensure that lower cap (7) is flush with front frame (6) .

  1. Measure gap (C) between front frame (6) and upper cap (4) at all three bolts. Use the smallest measurement (C) to determine correct thickness of shims.

  1. Install shims (5) of thickness (C) under upper cap (4).

  1. Install seven bolts (3) .

  1. Tighten seven bolts (3) to a final torque of 105 ± 20 N·m (75 ± 15 lb ft).

(5) 5K-0988 Shim Pack

(8) Bolts

Use the following procedure to install bolts (8) .

  1. Install two bolts (8). Do not install the bolts in adjacent holes.

  1. Tighten the two bolts (8) to a preliminary torque of 135 ± 14 N·m (100 ± 10 lb ft).

  1. Measure gap (D) between frame (11) and plate (9). Use the smallest measurement (D) to determine the correct thickness of shims.

  1. Install shims (10) that are the same thickness as measurement (D) minus 0.25 mm (0.010 inch).

  1. Install four bolts (8) .

  1. Tighten four bolts (8) to a final torque of 240 ± 40 N·m (175 ± 30 lb ft).

Note: Apply 4C-4030 Thread Lock Compound to the threads before installing four bolts (8). Tighten four bolts (8) in the sequence that is shown.
