These instructions must be read thoroughly before installation or operation. This instruction manual was accurate at the time of
printing. Please see dodgeindustrial.com for updated instruction manuals.
WARNING: To ensure the drive is not unexpectedly started, turn o and
lock-out or tag power source before proceeding. Failure to observe these
precautions could result in bodily injury.
WARNING: Because of the possible danger to person(s) or property from accidents which may result from the improper use of products, it is
important that correct procedures be followed. Products must be used in accordance with the engineering information specied in the catalog.
Proper installation, maintenance and operation procedures must be observed. The instructions in the instruction manuals must be followed.
Inspections should be made as necessary to assure safe operation under prevailing conditions. Proper guards and other suitable safety devices
or procedures as may be desirable or as may be specied in safety codes should be provided, and are neither provided by Dodge®nor are the
responsibility of Dodge. This unit and its associated equipment must be installed, adjusted and maintained by qualied personnel who are familiar
with the construction and operation of all equipment in the system and the potential hazards involved. When risk to persons or property may be
involved, a holding device must be an integral part of the driven equipment beyond the speed reducer output shaft.
WARNING: All products over 25 kg (55 lbs) are noted on the shipping
package. Proper lifting practices are required for these products.

STRAIGHT BORE BUSHING KIT
Loosen the six set screws in the hollow bore shaft and insert
the keyed bushing and supplied key into the side of the hollow
bore shaft that will be closest to the driven equipment. Line up
the clearance hole in the bushing with the set screw. Insert the
straight bore bushing into the hollow bore shaft on the opposite
side of the reducer and line up the two clearance holes in the
bushing with the set screws. Apply anti-seize compound to the
driven shaft and slide the reducer onto the driven shaft. Hand
tighten one of the set screws and then hand tighten a set screw
in the same position on the opposite side of the reducer. This
will take up the clearance between the shaft and reducer to the
same side and reduce wobble. Continue the alternating hand
tightening until all the set screws have been tightened. After all
the set screws have been hand tightened, use a torque wrench to
tighten the set screws to the values in the chart below. The 10-32
set screw over the key should be tightened to 3 ft-lb.

WARNING: If washers are supplied, it is extremely important to use
them with the screws when attaching the base. The supplied screws
MUST be tightened to the torque values listed below. The torque
values listed are based upon the use of the supplied fasteners
which are pre-coated with a thread locker that can only be used
once. If a screw is removed during initial installation, the screw must
be discarded and replaced with a new pre-coated screw. Failure
to follow the above procedure may result in serious injury or death
from falling items.

PLUG-IN SHAFT KIT
Install a snap ring on the plug-in shaft near the shaft extension
end. Insert the bore key into the key seat in the plug-in shaft.
Remove the two keyway set screws and loosen the remaining
four set screws in the hollow bore shaft in the reducer. (The
keyway set screws may be used but are not required.) Holding
the plug-in output shaft extension, slide the plug-in shaft into
the hollow bore. Install the second snap ring into the groove in
the plug-in shaft on the non-drive end. Hand tighten one of the
four set screws and then hand tighten a set screw in the same
position on the opposite side of the reducer. Continue to alternate
tightening the set screws until all four set screws have been hand
tightened. After all the set screws have been hand tightened,
use a torque wrench to tighten the set screws to the values in the
table below.
NOTE: Apply a thread-locking compound to the raised diameters
on the plug-in shaft before inserting into the reducer for improved
performance.

Install the fulcrum at an angle not more than 30 degrees from the
motor centerline using customer supplied hardware. The tie rod
assembly length can be adjusted by rotating the tie rod assembly
turn buckle. Tighten the tie rod assembly mounting hardware.
Tighten tie rod assembly jam nuts against the turn buckle to lock
