Measure the thickness of retainer (7) at the three small holes. Calculate the average thickness and record the average thickness.
Illustration 10 g01206462
Note: Bolts (9) cannot be reused. Always install new bolts.
Position retainer (7). Install three bolts (9) finger tight in the locations shown in Illustration 10.
Tighten three bolts (7) to a torque of 100 15 N m (74 10 lb ft).
Rotate the wheel for one revolution and tighten three bolts (9) again to a torque of 100 15 N m (74 10 lb ft).
Loosen three bolts (9) .
Tighten three bolts (9) to a torque of 34 7 N m (25 5 lb ft).
Rotate the wheel for one revolution and tighten three bolts (9) again to a torque of 34 7 N m (25 5 lb ft).
Illustration 11 g01206463
Measure the distance from retainer (7) to the end of the wheel spindle. Measure the distance through the three small holes in retainer (7) .
Record the average of the three depth measurements. Determine the difference between the average thickness that was measured in Step 10 and the average depth that was measured in Step 17. The difference is the gap that is between the retainer and the end of the spindle.
