Instruction Manual DODGE® TORQUE-ARM™ Speed Reducers These instructions must be read thoroughly before installation or operation. 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. 1. Use eyebolts to lift reducer. 2. Determine the running positions of the reducer. (See Fig. 1) Note: The reducer is supplied with either 4 or 7 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. Intall filter/ breather in topmost hole. Of the 3 remaining plugs on the sides of the reducer, the lowest one is the minimum oil level plug. Vertical Installations—Install the filler/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 5 remaining holes on the sides of the reducer, use a plug in the upper housing half for the minimum oil level plug.

However, if running position is over 20º 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 20º in positions “B” and “D” or 5º in positions “A” and “C” of the positions shown in Figure 1. Because of the many possible positions of the reducer, Figure 2 - Mounting Positions

Figure 2 - Installation of Sheave 5. Install motor and V-belt drive so belt 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 with the torque arm screw. (See Fig. 4.) Make sure that there is sufficient take-up in the turnbuckle for belt tension adjustment when using V-belt drive Right Angle or may vary 30˚ in tension 20˚ in compression V– Belt
