Installation Instructions and Safety Precautions
Inline and Right-angle Planetary Products - VR/EV Series
Inspection and Preparations
A. Upon delivery of the gearbox, confirm that you
received the exact model that was specified on your
purchase order.
B. Inspect for shipping damage. Notify the shipping
agent immediately if any damage is discovered.
C. Remove the protective covering from the
output shaft.
D. Clean and de-grease the motor mounting surface
and shaft, as well as the gearbox mounting surface,
input hub bore, and shaft bushing (if included). This
cleaning is very important for the shaft and bushing,
to prevent slip during motion.
Motor Mounting
A. Remove the access hole plug, allowing access to the
motor shaft clamp.

B. Carefully align the shaft bushing (if included)
so that the opening in the bushing aligns with
the opening in the input hub. It is also recom-
mended that the motor shaft keyway (if present)
aligns with the opening in the input hub clamp.
C. Rotate the gearbox input hub so that the clamp
bolt is aligned with the access hole. Loosen the
clamp bolt.
D. Remove the motor key (if supplied), as it is not
required for proper installation and operation.
E. Slowly slide the motor into the gearbox, so that
the motor shaft enters the gearbox input hub
with motor shaft keyway (if present) aligned with
gearbox input shaft clamp opening. Install the four
motor flange bolts in a cross-wise pattern, to ensure
proper alignment of motor to gearbox. Tighten the
bolts to the proper torque using a torque wrench
(see Table A).
