Information:

If there is a failure of the generator windings the generator can be rewound. A correct rewind job will return stator and rotor to like new condition. Four items are very important when rewinding any Caterpillar Generator.Type Wire
The correct AWG (American Wire Gauge) size and number wire must be used. This can be found in the rewind data. The type of wire must be that called for by NEMA standard MW1000 section MW24C. Use of wire other than that called for by this NEMA standard may cause a failure of the generator.Varnish
The varnish must have a class F rating. A high strength 100 percent fill epoxy varnish is recommended. This is the best type material to use.Balance
Rotors that have been rewound and varnished must be dynamically balanced. Balance the rotor to a displacement of no more than .0005 in. (0.013 mm) peak to peak. Vibration caused by a rotor that is not correctly balanced can damage the generator.Resistance
Resistance measurements will be accurate only if made with instruments able to measure very low resistance. A Wheatstone or Kalvin bridge is recommended. Do not use an ohmmeter.Resistance values are correct only at the given temperature. If the temperature of the windings is different than that given, use the formula that follows to find the actual resistance: 2 Parallel Star Connected
