(24) SpacerNote: The same adjustment is used for both the front pinion assembly and for the rear pinion assembly.
Install bearing cups (7) and (9) in housing (8). The bearing cups must be seated against the shoulders in housing (8).Note: If you freeze the bearing cups, allow the parts to reach a uniform temperature. Then use a driver or a press to reset the bearing cups. The limit for freezing the bearing cups is −29°C (−20°F). Remove any frost and wipe the bearing cups dry. Lubricate the bearing cups with SAE 30W gear oil to prevent rusting.
Install bearing cone (6) on pinion (5). Bearing cone (6) must be seated against the shoulder on pinion (5). Lubricate bearing cone (6).Note: If you heat the bearing cones, allow the parts to reach a uniform temperature. Then use a driver or a press to reset the bearing cones. The limit for heating the bearing cones is a maximum of 135°C (275°F) for a maximum of 4 hours. Lubricate the bearing cones with SAE 30W gear oil after the bearing cones have cooled to prevent rusting.
Install pinion (5) in housing (8). Press bearing cone (10) onto the shaft. Leave a small amount of end play. Lubricate bearing cone (10).
Position the assembly vertically in a soft jawed vise. Tighten the vise against the teeth on pinion (5).
Install spacer (24) and yoke (23). Then install shims (22), retainer (11), and bolt (12). Tighten the bolt to 105 20 N m (77 15 lb ft).Note: If components were replaced, use about 70% of the previous shim pack to start.
Secure the housing in the vice to check preload rolling torque. Check the rolling torque on bolt (12) with a torque wrench. Compare the values with the specifications listed in Table 1. If the preload exceeds the specification, remove the bolt and retainer. Move the pinion up and down to allow the bearings to reset. Install extra shims and recheck the rolling torque until it within specifications.
If the preload torque is below specifications, remove shims and recheck the rolling torque until it within specifications.
