GENERAL INFORMATION
Ball bearings are removed using tools which apply force
against one or both (inner and outer) bearing races. If the
force is applied against only one race (either inner or
outer), the bearing will be damaged during removal and
must be replaced. If the force is applied against both races
equally, the bearing will not be damaged during removal.
Both examples ruin the bearing
Ball bearings are cleaned in high flash-point solvent then
dried with compressed air. Air dry the bearing while
holding both races to prevent it from spinning. If the bear-
ing is allowed to spin, the high speed generated by the air
jet can overspeed the bearing and cause permanent
damage.
Ball bearings are checked (after cleaning) by slowly
rotating the inner race while holding the outer race sta-
tionary. If any radial play or roughness is felt, it must be
replaced. The bearing should have no axial play; if it has
noticeable axial play, it must be replaced.
Ball bearings are always installed with the manufacturer's
name and size code facing out. (Facing out meaning-the
name and sizing code should be visible from the side the
bearing is lnstalled from.) This is true for open, single-
sealed and double-sealed bearings. Apply the proper
grease t o open and single sealed bearings before
reassembly.

Snap rings are always installed with the chamfered (rolled)
edge facing away from the thrust of the mating part. This
way, pressure against the snap ring presses against the
areas in the snap ring groove with the most parallel con-
tact area against one another. Installed incorrectly,
pressure against the rolled or chamfered edge could com-
press the snap ring with the possibility of dislodging it.
Never reuse snap rings since they are often used to control
end play and become worn with normal use. Wear is
especially critical on snap rings which retain spinning parts
such as gears. After installing a snap ring, always rotate it
in its groove t o be sure it is fully-seated.
Grease or oil sliding or turning parts with the recommend-
ed lubricant before reassembly.
Replacement parts and fluids must be genuine Honda or
recommended by Honda. The use of non-Honda parts and
non-recommended fluids can have an adverse affect on
performance and durability.
Reassembly operation should be tested, whenever possi-
ble, before the part is installed onto the motorcycle.
