Adjust Idler Roller Bearings
Adjust idler roller bearings to keep dirt, grass,
and other foreign matter from damaging bearings
as needed when hubs become loose.
1. Remove dust cap (1).
2. Ensure bearings are properly seated by
tightening castle nut (2) to 30-40 ft•lb (40.7-
54.2 N•m) while turning the hub (3).
3. Loosen the castle nut (2).
4. Hand-tighten the castle nut.
5. Insert the cotter pin (4) into the wheel spindle
(5).
6. Bend the legs of the cotter pin over the top of
the spindle.
7. Clean the lip seal on the bearing cap and
replace using Loctite
®
242.
IMPORTANT: Do not move the hub after this
step is completed.
IMPORTANT: If cotter pin cannot be inserted,
loosen the castle nut until it can be.
IMPORTANT:
• When assembled correctly, the castle nut
should be free to move by hand with only
the cotter pin holding it in place.
• The hub should not have noticeable
movement when rocked back and forth.
