Lift the front of the vehicle and support on jack stands as
detailed in Section B of this manual. Rotate the front
wheel and feel for any roughness. Grasp the outside of
the tire and rock it. If any movement is detected, the
wheel bearing may require replacement/adjustment.
Remove the front wheel from the fork, proceeding as
described above. Remove the wheel from the axle, (Ref
Fig. 1 on page P-1). Remove the nuts and spacer secur-
ing the bearing assembly on the axle (Ref Fig. 2 on page
P-2). Remove the grease seal from the axle and gently
tap out the roller bearing. Clean the roller bearing with
solvent and dry thoroughly. Inspect the rollers for signs of
damage/wear. Pitting or blue coloration of the rollers will
indicate the need for replacement. If the rollers need
replacing, the bearing race must also be replaced. It may
be removed by tapping out from the other end of the hub
through the bore. Tap out in a circular pattern to prevent
damage to the hub bore.
Packing Wheel Bearings
The front wheel bearings are tapered roller type and
must be packed with grease at installation or any time
the bearing is removed for inspection. It is recommended
that a bearing packer attached to a grease gun be used;
however, manual packing is acceptable if done correctly.
Packing a bearing manually requires placing a dab of
grease in the palm of the hand and dipping the bearing in
the grease. Force the grease up through and around all
of the rollers until the entire bearing is coated in grease.
Fill the area between the rollers with grease and apply a
light coating to the bearing race. Install bearings into hub.
Seal Installation
Clean the hub seal surface to remove grease and press
the seal into place with the flange side of the seal facing
into the bore (Ref Fig. 3 on page P-2). Tap gently into
place with a seal installation tool until it is flush with the
outside of the hub assembly. Lubricate the seal surface
with grease.
Bearing Adjustment
Assemble axle bearings and grease seals in hub (Ref
Fig. 2 on page P-2). Assemble wheel and tire with lug
nuts (item 1). Tighten wheel nuts (item 1) to 70 - 100
ft.lbs. (95 - 140 N.m.) torque. Install axle assembly into
front fork (item 6) using jam nut (item 3) flat washer (item
6), lock washer (item 7) and nut (item 8) (Ref Fig. 4 on
page P-3). Rotate the hub while tightening the inner
(bearing adjusting nut) (item 2) until drag can be felt
while rotating wheel. Slightly loosen the bearing adjust-
ing nut to permit free movement of the wheel but with no
lateral play. Loosen the jam nut (item 3) and while hold-
ing the bearing adjusting nut (item 2) firmly, tighten the
jam nut against the bearing adjusting nut to 15 - 30 in.
lbs. (1.69 - 3.39 Nm) torque.
Tighten outer jam nuts to 70 - 80 ft. lbs. (95 - 105 Nm)
torque while holding inner nuts with a wrench.
