OVERLOAD CHECK:
2. Allow motor to cool and reset overload if necessary.
3. Remove motor end bell and stator, if necessary.
4. Check terminals 1 and 3 on overload. No continuity replace overload. Use a volt–ohm meter. See Figures 5
and 6.
MOTOR CHECK:
The resistance readings on the windings will be between 5 to 25 ohms. A meter capable of these low readings
must be used. The Start Relay cover must be removed. NOTE: Gear motor and related components can be
checked from Pin Connector. See Figures 5 and 6.
If no continuity on start or run winding test, replace stator. If continuity on grounded motor test, replace stator.
INSTALLATION AND SHAFT SEAL REPLACEMENT
(See Figure 6)
1. Place shaft seal locator seat over gear motor output shaft, embossed side down, and push down until shaft
seal seat rests flush on top of gear motor.
2. Place rubber coated ceramic seal (important: ceramic face up) over output shaft and push down until seal rests
on top of the shaft seal seat. (Lubricate rubber on ceramic seal with [#06195] rubber lubricant.)
3. Place shaft seal with carbon face down(spring up) over output shaft and push (gently) downward until seal
rests on carbon face of the output shaft seal.
4. Push down on the washer compressing the spring on the output shaft seal. While holding the seals (down) in
place slide the E–ring into the groove on the output shaft.
