Installation
Assemble torque arm bracket to conveyor per instal-
lation instructions found on page 18.
To aid in the installation of the reducer onto the shaft,
remove any protective coating film from shaft. Slide
the reducer onto the drive shaft extending from the side
of the conveyor head section. Using the instructions
and hardware supplied with the reducer, assemble it to
the conveyor drive shaft.
Assemble motor mount to the reducer. Refer to instal-
lation instructions provided with motor mount.
Install the rear panel of the drive guard before mounting
the sheaves. The rear panel has four (4) mounting brack-
ets with slotted holes. Attach the lower brackets to the
matching reducer assembly bolts. Attach the upper
brackets to the matching holes in the front motor mount
support.
Assemble the V-belt driven sheave to the input shaft of
the shaft mount reducer. Slide the sheave hub onto the
shaft and insert the square key. Attach the hub sheave
using the supplied retaining screws. The retaining screws
pass through the non-threaded holes of the hub and
into the sheave. Align the driver and driven sheaves
and tighten the retaining screws. During tightening, it is
Install the front drive guard panel over the four
corner mounting studs. Secure with washers and
nuts provided.
Fill the shaft mount reducer with the manufacturer’s
recommended oil. A list of recommended oil can be
found in the gear reducer instructions.
Adjustment of V-belt tension is achieved by tighten-
ing the hex nuts located on the four (4) jackscrews
of the motor base. Adjust motor base equally at all
four bolts to maintain shaft alignment. Belts are
designed to fit loose upon installation. When the
V-belt tension is correct, tighten the top nut on the
jackscrews to lock the motor base in position.
Proper tension is 1/64" of deflection per one (1") inch
of sheave centers on one side of belt, centered be-
tween sheaves.
Note: Too much tension shortens belt life. Check
belt tension frequently during the first 24-48 hours
of operation.

possible for the sheave to move out of alignment or be-
come out of square. For maximum V-Belt life, the driven
sheave should remain both perpendicular to the drive
shaft and aligned
with the drive sheave. Slip the V-belts
over both the driver and driven sheaves.
