MOTOR REPLACEMENT
The actuator motor used in Type VR,
VCR, and VLR switches with serial
numbers below those listed in Table 4 is
no longer available. To adapt the new
motor to these switches a motor
replacement kit, KA725VR, is available.
The kit includes the new motor and all
par ts required for the adaptation.
Replacement instructions are included
with the kit.
Switches with serial numbers above
those referenced in Table 4 have the
new design motors installed during
manufacture and do not require the
replacement kit. They may be replaced
directly on a one-to-one basis.
To replace a motor simply disconnect
the motor leads and remove the attach-
ing hardware. Make sure the drive gear
on the motor shaft meshes correctly
with its mating reduction gear when
installing the new motor.
