ing into the outer edge of the grease pile clos-
est to the thumb forcing grease into the interior
of the bearing between two adjacent rollers.

7.6.10 Axle bearing adjustment
1. Install the bearing and washer into the hub.
Thread on the inner nut, rotate the hub and
tighten the nut to 100 lbf ft (136 N m) of torque.
2. Loosen the nut to remove the pre-load
torque. Do not rotate the hub.
3. Hand tighten the nut, then back it off ¼ to ⅜
turn.
4. Place the tang washer on the spindle and
bend two tangs inward over the nut. This will
keep the inner nut from turning while torque
is applied to the outer nut.
5. Install the outer nut and torque it to 150 –
175 lbf ft (136 – 233 N m). Insure that the inner
nut does not turn. Bend two tangs from the
tang washer over the outer nut flats to secure.
6. Install cap with the O-ring and plug installed.
Rotate the hub and check the bearing adjust-
ment. The allowable end play is .001" – .010".
