14.Carefully pull rotor (ap) from stator (am) with upper bearing (ao)

and lower bearing (ar) assembled.

Note: Use caution when pulling rotor to avoid scratching the outer

surface of the rotor. If necessary, position pump in vertical

position and use puller or other means to draw the rotor up

and out of the stator without any side to side movement.

6.6.2.2 Motor Inspection

1. Visually inspect rotor (ap) for corrosion, wear or damaged threads.

2. Measure the rotor (ap) for deflection using a dial gauge.

—Deflection at the center of the rotor should not exceed 0.10mm

(0.0039in).

—Deflection at the pump end of the shaft should not exceed

0.08mm (0.0031in).

3. Measure shaft diameter of rotor (ap).

—Shaft diameter wear should not exceed 0.10mm (0.0039in).

4. Visually inspect the upper bearing (ao) and lower bearing (ar) for

wear, corrosion or rust. Manually test the for any side to side

movement or vibration.

—Replace every 6,000 hours of service or one year, whichever

comes first.

5. Visually inspect mechanical seal (ms) for wear, cracks or damage.

Look carefully at flexible components, replace if deformed.
