1. Lower the temperature of bearing cup (11) . Install bearing cup (11) in the pinion housing, as shown.

   Note: Reset the bearing cup with a suitable driver after the mating parts have reached a uniform temperature.

2. Install O-ring (12) on the pinion housing.

7. Heat bearing cone (8) to a maximum temperature of 135°C (275°F). Install bearing cone (8) on pinion shaft (4) .

   Note: Do not reset the bearing cone at this time.

8. Use SAE 30W gear oil to lubricate the bearing.

11. Attach Tooling (C) to the yoke. Install the yoke and Tooling (C) on the pinion shaft.

12. Use a torque wrench and Tooling (C) to slowly turn the pinion shaft. Check the rolling torque.

    The proper rolling torque is 0.7 to 1.4 N·m (6.23 to 12.46 lb in) for new bearings. If the existing bearings are used, limit the rolling torque to half of the specification.

    Note: If the rolling torque exceeds the specification, back off the shaft by a 1/8 turn. Reseat the bearings and repeat Steps 11 and 12.

Completed Stake (E) The spherical radius of the tool for peening must be 7.5 to 8.0 mm (0.295 to 0.315 inch). (F) The acceptable angle of the tool for peening is 20 ± 10 degrees. (G) The minimum length of the crimp is 4.7 mm (0.185 inch). (H) The minimum depth of the crimp is 2.5 mm (0.098 inch). (J) Top view

Note: Before you stake the nut, make sure that the pinion shaft has zero end play.

13. When the rolling torque is correct, stake nut (6) by peening the collar in slot (5) in the pinion shaft. See Illustration 11 and the caption for the correct dimensions.
