INSPECTION
1. INSPECT ROTOR
(a) Inspect the rotor for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the slip rings.
Standard resistance: 2.1 - 2.5 W at 20°C (68°F)
If there is no continuity, replace the rotor.
(b) Inspect the rotor for ground.
Using an ohmmeter, check that there is no continuity be-
tween the slip ring and rotor.
If there is continuity, replace the rotor.
(c) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(d) Using vernier calipers, measure the slip ring diameter.
Standard diameter: 14.2 - 14.4 mm (0.559-0.567 in.)
Minimum diameter: 12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.
2. INSPECT STATOR (DRIVE END FLAME)
(a) Inspect the stator for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the coil leads.
If there is no continuity, replace the drive end frame assembly.
(b) Inspect the stator for ground.
Using an ohmmeter, check that there is no continuity be-
tween the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.

3. INSPECT BRUSHES
Using a vernier caliper, measure the exposed brush length.
Standard exposed length: 10.5 mm (0.413 in.)
Minimum exposed length: 1.5 mm (0.059 in.)
If the exposed length is less than minimum, replace the brushes
and brush holder assembly.
4. INSPECT RECTIFIERS (RECTIFIRE HOLDER)
(a) Check the positive (+) rectifire.
(1) Using an ohmmeter, connect one tester probe to the
positive (+) terminal and the other to each rectifier
terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
shows no continuity.
If continuity is not as specified, replace the rectifier holder.
(b) Check the negative (-) rectifire.
(1) Using an ohmmeter, connect one tester probe to
each negative (-) terminal and the other to each
rectifier terminal.
(2) Reverse the polarity of the tester probes and repeat
step (a).
(3) Check that one shows continuity and the other
shows no continuity.
If continuity is not as specified, replace the rectifier holder.
5. INSPECT BEARING
Check that bearing is not rough or worn.
If necessary, replace the bearing (See page CH-1 1).
