Use three bolts (5) that are spaced 120° from each other in order to assemble retainer plate (2) to pin (7). Do not use shims (9) at this time.
Evenly, tighten bolts (5) to 200 25 N m (148 18 lb ft). Install bolts (4) and washers, but do not tighten bolts (4) at this time. Note: The chamfer on the inside of thrust washer (8) must face away from bearing (10). The chamfer allows clearance for the radius on the thrust face of pin (7).
Use a depth micrometer in order to measure the distance from the top of retainer plate (2) to the end of pin (7). Measure this distance through the hole in retainer plate (2).
Remove bolts (1) and retainer plate (2). Use an outside micrometer in order to measure the thickness of retainer plate (2).
Subtract the thickness of retainer plate (2) from the distance that was found in Step 3. This is the gap between pin (7) and retainer plate (2).
Add 0.25 mm (0.010 inch) to the distance that was found in Step 5. This is the shim pack thickness. Install the correct amount of shims from shim pack (9).
Use six bolts (5) and washers in order to install retainer plate (2) and shims (3). Torque bolts (5) to 750 90 N m (553 66 lb ft).
Tighten bolts (4) with washers to 475 50 N m (350 37 lb ft). Then, rotate bolts (4) by an additional 60 5 degrees. Note: Apply 4C-5593 Anti-Seize Lubricant to the washer face and to the threads prior to assembly.
