INSTALLATION
1. Use lifting bracket to lift reducer.
2. Determine the running positions of the reducer. (See Fig. 1)
Note that the reducer is supplied with 6 plugs; 4 around the
sides for horizontal installations and 1 on each face for vertical
installations. These plugs must be arranged relative to the
running positions 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 filter/ventilation plug in shipment and install plug
in topmost hole. Of the 2 remaining plugs on the sides of the
reducer, the lowest one is the minimum oil level plug.
Vertical Installations - Install the filter/ventilation plug in the
hole provided in the upper face of the reducer housing as
installed. If space is restricted on the upper face, install the vent
in the highest hole on the side of the reducer per Figure 1.
Install a plug in the hole in the bottom face of the reducer. Do
not use this hole for the magnetic drain plug. Of the remaining
holes on the sides of the reducer, use the plug in the upper
housing half for the minimum oil level plug.

Below 15 RPM output speed, oil level must be adjusted to reach the highest
oil level plug. If reducer position is to vary from those shown in Figure 1, either
more or less oil may be required. Consult Dodge.
The running position of the reducer in a horizontal application is
not limited to the four positions shown in Fig. 1. However, if
running position is over 20° in position "B" & "D" or 5° in position
"A" & "C", either way from sketches, the oil level plug cannot be
used safely to check the oil level, unless during the checking,
the torque arm is disconnected and the reducer is swung to
within 20° for position "A" & "C" or 5° for position "B" & "D" of
the positions shown in Fig. 1. Because of the many possible
positions of the reducer, it may be necessary or desirable to
make special adaptations using the lubrication filling holes
furnished along with other standard pipe fittings, stand pipes
and oil level gauges as required.
3. Mount reducer on driven shaft as follows:
WARNING: To ensure that drive is not unexpectedly started,
turn off and lock out or tag power source before proceeding.
Remove all external loads from drive before removing or
servicing drive or accessories. Failure to observe these
precautions could result in bodily injury.
For Taper Bushed Reducer: Mount reducer on driven shaft
per instruction in Torque-Arm II Bushing Installation section of
this manual.
4. Install sheave on input shaft as close to reducer as practical.
(See Fig. 2)
5. If not using a Dodge Torque-Arm II motor mount, install
motor and V-belt drive so belt will approximately be at right
angles to the centerline between driven and input shaft. (See
Fig. 3) This will permit tightening the V-belt with the torque arm.
6. Install torque arm and adapter plates reusing the reducer
bolts. The adapter plates will fit in any position around the input
end reducer.
7. Install torque arm fulcrum on a flat and rigid support so that
the torque arm will be approximately at right angles to the
centerline 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.
