Wheel Bearings
Refer to the INSPECTION section of this chapter
for information on when to replace the wheel
bearings.
Wheel bearing construction:
• A pair of tapered Timken® roller bearing cones
support the axle in each front hub. Both bearing
cones ride in a one-piece cup (race) that is
shaped like the middle third of an hour glass.
• The cup is held into the hub by a retaining ring at
the outside. The inside edge seats against a
shoulder that is machined into the hub.
• Bearing pre-load is set by the torque of the axle
nut. Over-tightening or under-tightening will
have an adverse effect on wheel bearing life.
• Press in seals protect and retain the bearing
cones in the cup.
Wheel bearing service intent:
• If damage is evident on either bearing cup,
replace both cups and the race. Bearing cups
and races should always be replaced as a pair.
It stands to reason that if one bearing on a wheel
is damaged, the other will have suffered as well.
• If there is reason to believe that the grease has
been contaminated, the bearings can be disas-
sembled, cleaned, inspected, re-packed, and
returned to service.
• After 1,000 hrs. or four years of service, re-pack-
ing the wheel bearings would be prudent.
To remove the wheel bearings:
1. Lift and safely support the vehicle as described
in the INTRODUCTION section of this manual.
The vehicle should be supported by the frame.
2. Remove the front wheel using a 3/4” wrench.
3. Remove the C-Clips from the brake caliper
mounting pins using a small screwdriver.
See Figure 4.53.
4. Remove the mounting pins (slide pins) using a 3/
8” allen wrench. See Figure 4.54.
