10-20. REPLACING SLIP RINGS. Slip rings that are damaged may be replaced. Two sizes
are available. The early rotor shaft was smooth and the slip rings were pressed on and the
ring cemented to the rotor fan. Later rotor shafts were knurled and the slip rings were
pressed on the knurled surface of the shaft.
The early slip rings have a smaller inside diameter and must be pressed on the smooth
rotor shafts ONLY.
The later slip rings have a larger inside diameter and must be pressed on the knurled
shaft ONLY.
There is also another difference in the rotor shafts installed on the late alternators. This
shaft has a grease retainer and an insulator. The retainer is pressed on over the insulator
ahead of the slip rings. These rotors are not interchangeable with rotors used on alternators
without the counterbore in the rectifier end shield.
