WHEEL BEARINGS
Removal of the wheel bearings neces—
sitates removing the hub oil seals. These
must be replaced with new ones upon
reassembly.
Disassembly
1. Remove the wheel. For the front
wheel remove the axle, side collar, and
brake plate (drum brakes), or the speed—
ometer drive housing (dise brakes). On
the rear wheel, remove the brake plate
and any side collars.
2. Remove any dust covers, or dust
seals. Unscrew the bearing retainer, iffit—
ted (all rear wheels; sprocket side and
disc brake, disc side).
3. Pry out the oil seal. An oil seal is fit—
ted to the disc side on dise brake wheels
and on the side opposite the brake plate
on wheels fitted with a drum brake. Use a
small screwdriver, or, preferably, an
elbow—shaped tool to remove the oil seal.
4. Remove the wheel bearings by
reaching through the center of the hub
with a long drift and tapping one of the
bearings evenly around its circumference
until it is removed. Be careful not to turn
the bearing sideways in its seat on re—
moval as there is danger of causing dam—
age to the hub.
