Use Tooling (E) to install Duo-Cone seal (9) into the retainer (9A). Refer toSpecial Instruction, "Assembly and Installation of Conventional Duo-Cone Seals". Install bearing cone (8) onto spindle (6). The weight of spindle (6) is approximately 27 kg (60 lb).Note: Inspect the Duo-Cone seals to verify that the Duo-Cone seals have not been damaged during the installation and remain clean and dry.

Use Tooling (C) to measure the thickness of retainer (4) at the three small holes in the retainer. Record the average of the three measurements.
Position retainer (4) onto spindle (6). Install three bolts into the holes beside the three small holes that were used for the measurements in Step 14. Tighten the three bolts to a torque of 100 N m (75 lb ft). Turn wheel (1) by several revolutions and tighten the three bolts to a torque of 100 N m (75 lb ft).
Loosen the three bolts. Tighten the three bolts again to a torque of 25 N m (18 lb ft). Turn wheel (1) by several revolutions. Repeat this procedure until the torque on bolts (3) remains at 25 N m (18 lb ft).
Illustration 11 g01197970
Use Tooling (D) to take three measurements of the distance to the end of spindle (6) through the three small holes. Record the average of the three measurements.
Subtract the average measurement that was found in Step 14 from the average measurement that was found in Step 17. Record the measurement as the average gap between the end of the spindle and the retainer.
Remove the three bolts.
Illustration 12 g01197963
The thickness of shims (5) must be equal to the gap that was determined in Step 18 plus 0.075 0.025 mm (0.003 0.001 inch).
Illustration 13 g01197955
Install shims (5), retainer (4), and bolts (3). Tighten bolts (3) to a torque of 60 12 N m (45 9 lb ft) and then turn the bolts 120° 10° . Do not reuse the bolts.
