1. Elevate the side of the machine where the
wheel is being inspected. A common hydraulic
floor jack may be used.

stand, positioned directly under nearside end of
machine chassis cross-member.

(12).
5. Unscrew the castle nut (counter-clockwise) and
remove the spindle washer.
6. Remove the hub (8) from the spindle, being
careful not to allow the smaller bearing race &
rollers (cone) (10) to fall out. The larger bearing
race & rollers (cone) (6) will be retained by the
seal (5).
Bearing Inspection
Wash all grease and oil from the bearing race & rollers
(cone) using a suitable solvent.
WARNING
Gasoline should not be used as a cleaning
agent because of fire and explosion danger.
Dry the bearing with a clean, lint-free cloth, and
inspect each roller completely. If any pitting, spalling,
or corrosion is present, then the bearing should be
replaced. The bearing cup inside the hub should
likewise be inspected.
NOTICE
Bearings must always be replaced in SETS: a
cone and a cup! If the bearing needs replaced,
replace the cup also. If the cup needs replaced,
replace the bearing also.
To replace a bearing cup
1. Place the hub on a flat work surface with the
cup to be replaced on the bottom side.
2. Using a brass drift punch, carefully tap around
the small diameter end of the cup to drive out.
