Assembly
1. CHAIN REDUCER DRIVE (For 36' thru 78' Diameter Bins)
Oil must be added before assembly. The chain
reducer is shipped without oil.
Do NOT add more oil than recommended. Addi-
tional oil may damage the seals or be forced out
through the vented fill plug.
For lubrication in normal operating temperature
between 40° F to 120° F, we recommend the use
of non foaming, multi purpose gear oil, SAE 90
weight. For temperatures below 40° F, use a SAE
80 weight oil. Use grade commercially available
for automotive differentials. Extra pressure
additives may be of value in severe applications.

(See Fig. 2 on page 15.)
1. First, fill the chain reducer drive with oil by removing
the vented fill plug and pouring 48 oz. of oil into drive.
Oil level can be checked by removing the check plug.
Oil should not be over the check plug. (See Fig. 1)
2. Install Pivot Bracket (1) to bottom of motor mount
frame (2) using a 3/4" x 11" long (grade 5) hex head
capscrew and nylon locknut.
3. Attach the electric cord support stand (3) and one side
of the motor mount support plate (4) to the motor
mount frame (2) using two 1/2" x 1-1/2" long (grade 5)
hex head capscrews with lock washers and hex nuts.
Attach the other side of the motor mount support plate
(4) to the motor mount frame (2) using two 1/2" x
1-1/4" long capscrews with lockwashers and nuts.
4. Mount the chain reducer drive (6) to the mounting ring
on the motor mount frame (2) with four 3/8" x 1" long
(grade 5) hex head capscrews and nylon locknuts.
5. Screw the 3/4" threaded adjusting rod (7) down through
the nut welded to the top of the motor mount support
plate (4). Leave the adjusting rod (7) an inch or two
above the top surface of the motor mount support
plate (4). The adjusting rod will be adjusted later after
the drive belts are installed.
6. Thread a 3/4" hex nut onto the bottom end of the
adjusting rod (7) underneath the motor mount support
plate (4). This nut is for locking the adjusting rod in
place after adjusting it to the required position to
tighten the drive belts. DO NOT tighten this nut
against the motor mount support plate until the belts
have been installed and tightened.
7. Align the pivot holes (10) of the motor mount plate (4)
with those in the motor mount support plate (4) and
slide the pivot rod (9) through the holes. Insert a 3/16"
cotter pin into the holes in each end of the pivot rod (9)
to keep it in place.
