motor body (1) are damaged or worn, Fairmont recom-
mends to replace the components as an assembly with
the bearings already pressed in.
1. Do not remove the needle bearings (2, 13) unless
they are damaged or worn. Bearings will be ruined
when they are removed.
2. Use a blind-hole bearing puller to remove the bear-
ings from the motor cap or motor body.
Inspection
Clean all parts with solvent and dry them thoroughly.
Inspect each component as described in this section.
Replace any component that shows wear or damage.
1. Bearings (4, 15) and Drive Shaft (3): Insert shaft into
bearings. Spin shaft. If shaft does not spin smoothly,
replace bearings and drive shaft.
2. Motor Cap (12) and Motor Body (1): Inspect mating
surfaces, gear cavities, oil passageways, etc. for
grooves or nicks. If any component shows wear or
damage, replace the component as an assembly
with the bearings already pressed in.
3. Inspect all other disassembled components for
cracks, grooves, or nicks.
