Installing Shaft Mount Reducers
Assemble torque arm bracket to conveyor per in-
stallation instructions found on page 17.
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 instruc-
tions 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 brackets 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
possible for the sheave to move out of alignment or
become out of square. For maximum V-Belt life,
the driven sheave should remain both perpendicu-
lar to the drive shaft and aligned with the drive
sheave. Slip the V-belts over both the driver and
driven sheaves.
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 jackscrews 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, cen-
tered between sheaves.
Note: Too much tension shortens belt life. Check
belt tension frequently during the first 24-48 hours
of operation.
