1. Before installing the motor into the HG:
a. Wipe the motor shaft, pilot, and mounting face
clean. Wipe the internal pilot and motor mounting
face of the HG clean.
b. Ensure that the HG’s clamp collar is positioned
over the slotted portion of the motor shaft bore
such that the slots do not line up.
c. Remove clamp collar access set screw.
d. Insert the long blade of a hex bit (included) through
the clamp collar screw access hole in the motor
adapter and engage with the clamp collar screw
head.
2. Apply a serviceable thread locking compound to the
threads of the motor face mounting screws and a thin
film of anti-sieze compound to the motor shaft.
3. Slowly and gently guide the motor into the input of the
HG. During this part of the procedure, the weight of
the motor should be adequately supported. Never
allow the motor to be suspended from HG until the
shaft and pilot diameter are fully inserted.
4. Once the motor shaft and pilot are fully seated within
the HG input, tighten the motor face mounting screws
according to Table 1. After the motor face screws are
tightened the clamp collar screw can be tighten, also
according to Table 1.
