TEST OR INSPECTION
(1) Remove setscrew (1), pulley (2) and
(2) Remove four thru bolts (4), fan guard
(8), lock-ring (9), fan (10), spacer (11), rear
end shield assembly (12), bearing (13), front
end shield (5), bearing (6), spring (7), rotor
and shaft (15), capacitor case (16),
capacitors (17 and 18), from stator frame and
Dry cleaning solvent, P-D-680, used to clean parts is potentially dangerous to
personnel and property. Use in a well ventilated area as the fumes are dangerous
if inhaled. Do not use near open flame or excessive heat. Flash point of solvent is
100 F. 138 F.
(3) Clean all parts except rotor, bearings
and stator in dry cleaning solvent, P-D-680,
and wipe dry with a lint free cloth.
(4) Use compressed air to clean dust and
dirt off rotor, bearings, and stator,
then wipe with a cloth dampened in dry
cleaning solvent P-D-680.
(5) Inspect bearings and rotor shaft for
excessive wear, and rough or scored
surfaces. Use a file or emery cloth to
smooth rough or scored surfaces. Replace
defective bearings or a defective rotor
shaft. If the motor is beyond repair,
replace the motor.
(6) Install capacitors (17 and 18), and
capacitor case (16) on stator frame and
base (23). Replace rotor and shaft (15),
spring (7), bearing (6), front end
shield (5), bearing (13), rear end shield
assembly (12), spacer (11), fan (10),
lockring (9), fan guard (8), and four thru
(7) Replace key (3) in shaft, pulley (2)
on shaft, and replace the setscrew (1).
replace mounting bolts.
g. Connect electrical leads.
h. Replace V-belts and slide motor away
proper tension. Tighten motor mounting
