6-11. GEARED HUB SPINDLE SEAL REPLACEMENT (Cont'd) 1. Using driver handle and spindle seal installer, install spindle seal (1) in geared hub (2). 2. Coat spindle seal (1) with lubricating oil. 3. Install spacer (3) and spindle (4) in geared hub (2). 4. Apply grease to face of retaining nut (9). NOTE • If four-slotted retaining nut is present, it is recommended to replace it with eight-slotted retaining nut 12342680. • Ensure lip of spacer faces the bearing for a proper fit. 5. Install spacer (5), bearing (6), keyed washer (7), lockwasher (8), and retaining nut (9) on spindle (4). 6. Using retaining nut wrench, tighten retaining nut (9) to 35-45 lb ft (47-61 N•m). 7.

Failure to do this may cause injury to per- sonnel or damage to equipment. NOTE • For new configuration, two locktabs on lockwasher must be bent into slots on retaining nut. • It may be necessary to slightly loosen or tighten retaining nut to gain proper alignment with locktabs. 9. Determine which locktab(s) (10) on lockwasher (8) aligns with slot(s) (11) in retaining nut (9). Bend locktab(s) (10) into slot(s) (11) on retaining nut (9). b.
