Note: Pay particular attention to the sealing faces that butt up

against each other. They are divided by a thin oil film which

prevents water from entering the motor. Replace entire

mechanical seal if worn, damaged or cracked. Replace every

6,000 hours of service or one year, whichever comes first.

6. Visually inspect the thermal switch (q) for damage to insulation

materials, water or oil intrusion, heat discoloration of bi-metal disc,

or damage to bi-metal disc. Check to assure the lead wires of the

stator windings are correctly and securely connected to the

protector. Check for disconnection of lead wires, short-circuit, coil-

burn, or incorrect wiring.

7. Visually inspect oil lifter (ad).

—Replace if worn or broken, paying particular attention to internal

paddles.

Note: The condition of the oil lifter not only effects lubrication, but

cooling as well.

6.6.3 Motor Testing

1. Dry stator (az) thoroughly and allow it to cool before testing.

2. Measure resistance between stator’s lead wire and motor frame

using Megger tester.
