Rotating the rotor using a lever
Turn the shaft using a sturdy lever. The shaft should turn smoothly and easily once movement begins.Note: The break-away force required to turn the rotor can be large on sleeve bearing motors.
Rotate 10 and one-quarter revolutions. Rotating the rotor will keep the bearings lubricated. The shaft will also be repositioned to avoid sitting on the same spot for an extended period.
Reinstall the shaft locking device. Ensure that the bolts of the shaft locking device are properly torqued.
