WARNING: To ensure the drive is not unexpectedly started,
turn off and lock-out or tag power source before proceeding.
Failure to observe these precautions could result in bodily
injury.
WARNING: All products over 25 kg (55 lbs) are noted on the
shipping package. Proper lifting practices are required for
these products.
INSTA LLATIO N
1. If applicable, remove the plastic plugs that protect the
threaded holes in the sides of the reducer housing and
install the lifting brackets supplied with the reducer.
2. Determine the running position of the reducer (Figure 1). Note
that the reducer housing has been machined for pipe plugs
around the sides of the reducer for horizontal applications
and in each face for vertical applications. The plugs must be
arranged relative to the running position as follows:
Horizontal Installations - Install the magnetic drain plug in
the hole closest to the bottom of the reducer. Throw away
the tape that covers the lter/ ventilation plug in shipment
and install plug in topmost hole. Of the remaining plugs on
the sides of the reducer, the lowest one is the minimum oil
level plug.
Vertical Installations -Install the lter/ventilation plug in the
hole provided in the top face of the reducer housing. Use the
hole in the bottom face for the magnetic drain plug. Of the
remaining holes on the sides of the reducer, use a plug in the
upper housing half for the minimum oil level plug.
The running position of the reducer in a horizontal application
is not limited to the four position shown in Figure 1. However,
if running position is over 20° in position “B” and “D” or
5° in position “A” and “C” either way from sketches, the oil
level plug cannot be safely used to check the oil level, unless
during the checking the torque arm is disconnected and the
reducer is swung to within 20° for position “B” or “D” or 5°
for position “A” or “C” of the positions shown in Figure 1.
Because of the many possible positions of the reducer, it
may be necessary or desirable to make special adaptations
using the lubrication tting holes furnished along with other
standard pipe ttings, stand pipes and oil level gauges as
required.

position.
5. Hoist reducer into position and slide it onto shaft aligning
hub keyway with key.
6. Align unthreaded holes of inboard bushing with threaded
holes of bushing back-up plate. If necessary, rotate the
bushing back-up plate to align holes. Insert screws and
tighten lightly.
7. Place the outboard bushing in position on the shaft aligning
the bushing keyway with the key. Align the unthreaded
holes in the bushing with the threaded holes in the back-up
plate, rotating the back-up plate if necessary. Insert bushing
screws and tighten lightly.

9. Install sheave on input shaft as close to reducer as possible.
10. Install motor and V-belt drive so belt pull will be roughly at
right angles to the center line between driven and input shaft
(Figure 2.) This will permit tightening V-belt drive with the
torque-arm.
11. Install torque-arm adaptor plates on the input end of the
re d ucer.
12. Install torque-arm fulcrum on a rigid support so that the
torque-arm will be approximately at right angles to the
center line through the driven shaft and the torque-arm
anchor screw (Figure 2). Make sure that there is sufcient
take-up in the turnbuckle for belt tension adjustment when
using V-belt drives.
13. Retighten bolts and pipe plugs after a few days' operation.
This prevents oil leakage.
LUBRICATION
NOTE: Because r educer is shipped without oil, it is necessary
to add the proper amount of oil before running.
Use a high-grade petroleum-base, rust and oxidation inhibited
(R&O) gear oil (Tables 1 and 2). 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 rst. Drain reducer and ush with
kerosene, clean magnetic drain plug and rell to proper level with
new lubricant.
CAUTION: Extreme pressure (EP) lubricants are not
recommended for average operating conditions. Failure to
observe these precautions could result in bodily injury.
CAUTION: Too much oil will cause overheating and too little
will result in gear failure. Check oil level regularly. Failure to
observe this precaution could result in bodily injury. 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 EP oils or oils containing slippery
additives such as graphite or molybdenum disulphide in the
reducer when backstop is used. These additives will destroy
sprag action.

GUIDELINES FOR TORQUE-ARM REDUCER
LONG-TERM STORAGE
During periods of long storage, or when waiting for delivery or
installation of other equipment, special care should be taken to
protect a gear reducer to have it ready to be in the best condition
when placed into service.
By taking special precautions, problems such as seal leakage
and reducer failure due to lack of lubrication, improper
lubrication quantity, or contamination can be avoided. The
following precautions will protect gear reducers during periods
of extended storage:
Preparation:
1. Drain oil from the unit. Add a vapor phase corrosion inhibiting
oil (VCI-105 oil by Daubert Chemical Co.) in accordance with
Table 3 .
2. Seal the unit airtight. Replace the vent plug with a standard
pipe plug and wire the vent to the unit.
3. Cover all unpainted exterior parts with a waxy rust
preventative compound that will keep oxygen away from
the bare metal. (Non-Rust X-110 by Daubert Chemical Co.
or equivalent).
4. The instruction manuals and lubrication tags are paper and
must be kept dry. Either remove these documents and store
them inside, or cover the unit with a durable waterproof
cover which can keep moisture away.
5. Protect reducer from dust, moisture, and other contaminants
by storing the unit in a dry area.
6. In damp environments, the reducer should be packed inside
a moisture-proof container or an envelope of polyethylene
containing a desiccant material. If the reducer is to be stored
outdoors, cover the entire exterior with a rust preventative.
When placing the reducer into service:
1. Assemble the vent plug into the proper hole.
2. Clean the shaft extensions with petroleum solvents.
3. Fill the unit to the proper oil level using a recommended
lubricant. The VCI oil will not affect the new lubricant.
Follow the installation instructions provided in this manual.
