Torque-Arm

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 off and

lock-out or tag power source before proceeding. Failure to observe these

precautions could result in bodily injury.

INSTALLATION

Remove backstop shaft cover and gasket (Figure 1). These

parts will not be reused. This cover is directly opposite the

extended end of the input shaft.

Clean the face of the gearbox to remove any gasket material

or contamination from the cover mounting surface. It is

important that contamination not get into the gearbox or the

backstop during the backstop installation/servicing process.

Face reducer looking at the side from which the cover

was removed. Determine carefully the desired direction of

free rotation. It is important that the direction be correctly

determined because to reverse the direction after the

backstop is installed, it is necessary to remove the backstop,

turn it end-for-end and then reinstall it.

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 specified 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 specified 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 qualified 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. An additional warning label has been

provided for the end user to place on speed reducer for convenience of

easy visibility.

II Speed Reducer Backstop Assemblies

Instruction Manual

WARNING: All products over 25 kg (55 lbs) are noted on the shipping

package. Proper lifting practices are required for these products.

Match the arrow on the backstop inner race to the direction

of free rotation for the desired direction of shaft rotation. Note

that reversing the backstop end-for end changes the direction

of the arrow. The shaft will rotate in the same direction as the

arrow on the backstop.

If the backstop kit has a spacer ring included, install it onto the

shaft first, adjacent to the bearing inner ring.

Install the backstop inner race and sprag cage assembly

onto the shaft. DO NOT remove the cage from the inner

race or the shipping strap from the sprag set at this time.

Insert the key into the inner race and mating shaft keyway.

These parts should slip onto the shaft easily, a light coating

of oil may assist in assembly. Do not use a hammer to force

the installation, damage can occur to the shaft and/or the

backstop. Slide the race against the spacer or the shaft

shoulder and install the retaining ring into the groove in the

shaft. Only use the supplied key, as it is specifically designed

for each backstop.

Apply a thin coating of RTV silicone onto the gearbox mating

surface for the outer race (same as the cover area). It is

important to apply the sealant around the fastener holes to

prevent leakage. Do not allow excessive amounts of silicone

to enter the gearbox or to be applied to other parts.

Install the outer race by gently rotating it opposite the shaft

rotation while pressing lightly inwards. Do not force the outer

race into position as backstop damage may occur. Once

the outer race is well piloted onto the sprag set, remove the

shipping strap from the sprag set by cutting it, being careful

not to let the outer race back off the sprags. The outer race

should slide easily into position with a slight turning motion.

A light coating of oil on the race inner diameter may ease

installation.

Align the fastener holes in the outer race with the mating

holes in the gearbox. Use the supplied grade 5 fasteners

and lock washers only. Torque the fasteners in an alternating

pattern per Table 1.
