Replacing the Rotor Assembly
Replacement rotor assemblies are available should the rotor shaft become damaged due to dropping,
bearing failure, or improper gearbox engagement. Use care when removing the encoder and brake
assemblies because they can be reused and new ones are not included with the replacement rotor
assembly. A rotor assembly consists of the shaft, integral fan and squirrel cage, and upper and lower
bearings. The unit is shipped preassembled along with a new shaft key. Be sure to use the antifretting
sleeve if your gearbox assembly originally came with one.
