NOTE
If multimeter does not indicate an
open circuit in either test, rotor coil is
grounded. Replace rotor.
(11)
Touch one test lead to bare metal surface
on shaft (8) and other test lead separately
to each slip ring (9).
NOTE
If resistance is not 10.0 ohms or less,
replace rotor.
(12)
Touch test leads to each slip ring (9).
NOTE
Minimum outside diameter (OD) of
slip rings is 1.057 in. (26.85 mm). If
measurement is less, replace rotor.
(13)
Measure outside diameter (OD) of slip
rings (9).
NOTE
Minimum outside diameter (OD) of
shaft is 0.669 in. (17 mm). If
measurement is less, replace rotor.
(14)
Measure diameter of shaft (8).

Cleaning/Inspection
WARNING
Dry cleaning solvent P-D-680 is toxic and flammable. Wear protective goggles and
gloves and use only in well-ventilated area. Avoid contact with skin, eyes, and
clothing, and don't breath vapors. DO NOT use near open flame or excessive heat.
The flash point is 100-138° F (38-59° C). If you become dizzy while using cleaning
solvent, get fresh air immediately and medical aid. If contact with eyes is made,
wash your eyes with water and get medical aid immediately.
CAUTION
Do not soak stator or rotor in solvents. Damage to insulation may result.
(1)
Clean stator and rotor with dry cleaning solvent and clean cloth.
WARNING
Compressed air for cleaning purposes will not exceed 30 psi (207 kPa). Use only
with effective chip guarding and personal protective equipment (goggles/shield,
gloves, etc.).
(2)
Dry stator and rotor with compressed air or dry cloth.
(3)
Clean all other components, except bearings, in dry cleaning solvent.
