Align the Rotor
Follow these steps to align the rotor prior to removing the motor.
1. Use a flashlight to illuminate all holes (A, B and C) in the housing.
To locate the holes, refer to the diagrams on
.
2. Turn the shaft by hand until a threaded hole directly aligns with each
hole B, and the hex bolts on the compression coupling are visible through
each hole A.
3. Verify each hole C shows the flat surface of the rotor.
The holes are not evenly spaced. If necessary, continue to slowly rotate the
shaft until the above conditions are met.
IMPORTANT
Correct alignment of holes A and B is critical for the successful release of the
compression coupling and the subsequent removal of the motor.
