ELECTRICAL SYSTEM
Bearing at Slip Ring Side
1. Lightly secure the rotor (1) with a vise to prevent damage, and
remove the bearing (2) with a puller (3).

(3) Servicing
Bearing
1. Check the bearing for smooth rotation.
2. If it does not rotate smoothly, replace it.
W1019790
Stator
1. Measure the resistance across each lead of the stator coil with an
ohmmeter.
2. If the measurement is not within factory specification, replace it.
3. Check the continuity across each stator coil lead and core with an
ohmmeter.
4. If infinity is not indicated, replace it.
W1019964
Rotor
1. Measure the resistance across the slip rings with an ohmmeter.
2. If the resistance is not the factory specification, replace it.
3. Check the continuity across the slip ring and core with an
ohmmeter.
4. If infinity is not indicated, replace it.
