Remove and Install a Shaft Key
Shaft keys for the BulletinVPS motors are constructed of stainless steel - 300 series with a
tolerance for interference fit (slightly larger than the opening) to provide a secure and rigid fit for
the mating connection.
To remove a shaft key, perform one of these actions:
•
Grasp the key with a plier or similar tool, and lift the key out of the key slot.
•
Insert a screwdriver between the key and the bottom of the key slot, and use a levering
action to lift the key out of the key slot.
To install a shaft key, follow these steps.
1. Verify that the replacement key matches the keyway in the shaft and the mating
mechanical connection, for example, a coupling or pulley, before proceeding.
2. Align the front of the key with the front of the motor shaft.
This prevents the curved end-of-cut at the motor end of the keyway from interfering
with the correct seating of the key.
3. Support the underside of the shaft diameter with a fixture, and use a controlled press
device to apply a constant force across the top surface to press the key into the shaft.

ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact is
applied to the shaft during installation of couplings and pulleys. Damage to the feedback device
can result from applying leverage to the motor mounting face when removing devices mounted on
the motor shaft.
Do not strike the shaft, couplings, or pulleys with tools during installation or removal. Use a wheel
puller to apply pressure from the user end of the shaft when attempting to remove any device from
the motor shaft.
Failure to observe safety precautions could result in damage to the motor and its components.
