4.
Mount reducer on driven shaft as follows:
For Straight Bore: Mount reducer on driven shaft as close
to bearing as practical. If bushings are used, assemble
bushing in reducer first. A set of bushings for one reducer
consists of one keyseated bushing and one plain bushing.
Extra length setscrews are furnished with the reducer. Driven
shaft should extend through full length of speed reducer.
Tighten both setscrews in each collar.
For Taper Bushed: Mount reducer on driven shaft per
instruction manual for tapered bushings.
5.
Install sheave on input shaft as close to reducer as
practical. (See Fig. 2.)
Figure 2 - Installation of Sheave
6.
Install motor and V-belt drive so belt pull will approximately
be at right angles to the center line between driven and input
shaft. (See Fig. 3.) This will permit tightening the V-belt drive
with the torque arm.
Figure 3 - Installation of Motor
7.
Install torque arm and adapter plates using the long
reducer bolts. The bolts may be shifted to any of the holes
on the input end of the reducer.
8.
Install torque arm fulcrum on a rigid support so that the
torque arm will be approximately at right angles (±30º) to
the center line through the driven shaft and the torque arm
anchor screw. (See Fig. 4.) Make sure that there is sufficient
take-up in the turnbuckle for belt tension adjustment when
using V-belt drive.

CAUTION: Unit is shipped without oil. Add proper amount
of recommended lubricant before operating. Failure to
observe these precautions could result in damage to, or
destruction of, the equipment.
9.
Fill gear reducer with recommended lubricant.
LUBRICATION
Use a high grade petroleum base, rust and oxidation inhibited
(R & 0) gear oil-see tables. Follow instructions on reducer
nameplate, warning tags, and in the installation manual.
Under average industrial operating conditions, the lubricant
should be changed every 2500 hours of operation or every 6
months, whichever occurs first. Drain reducer and flush with
kerosene, clean magnetic drain plug and refill to proper level
with new lubricant. Check oil level regularly.
CAUTION: Extreme pressure (EP) lubricants are not
recommended for average operating conditions. Failure to
observe these precautions could result In damage to, or
destruction of, the equipment.
CAUTION: Too much oil will cause overheating and too
little will result in gear failure. Check oil level frequently.
Failure to observe these precautions could result in
damage to, or destruction of, the equipment.
Under extreme operating conditions, such as rapid rise and fall
of temperature, dust, dirt, chemical particles, chemical fumes, or
oil sump temperatures above 200"F, the oil should be changed
every 1 to 3 months depending on severity of conditions.
CAUTION: Do not use oils containing slippery additives
such as graphite or molybdenum disulphide in the reducer
when backstop is used. These additives will destroy sprag
action. Failure to observe these pre-cautions could result
in damage to, or destruction of, the equipment.
