Direct drive application with the Torq/
Gard
®
clutch mounted on the low speed
output shaft of the reducer. The Torq/
Gard clutch is shown with a Browning
®
Ever-Flex
™
half coupling which mounts on
the clutch adapter without modification.
Browning chain coupling kits are also
available for the Torq/Gard clutch when
greater misalignment capabilities are
required. Either side of the Torq/Gard
clutch can be used as the input.
The Torq/Gard clutch should not be used
on the high speed input side of the
reducer. Clutch sensitivity becomes a
function of the reducer’s gear ratio. As
an example, when used with a 100 to 1
reducer, a 100 inch-pound torque variation
on the output side will reflect only a 1
inch-pound change on the input side. Do
not exceed the maximum RPM shown in
the Torq/Gard clutch selection table.
Mounting the clutch on the output of the
gear motor or reducer provides the most
economical clutch assembly. The Torq/
Gard clutch is designed to protect the
weakest link in the drive system.
The Torq/Gard clutch is mounted on the
driven machine and powered through a
chain and sprocket drive. Mounting the
clutch in this position tends to absorb
peak starting torques.

The Torq/Gard
®
clutch is delivered with the torque set at the low
end of its torque range.
1. Turn the single hex-socket head adjusting nut clockwise to
increase the torque setting. (Refer to Table E.) Note: 1/2 inch
hex-keyed (allen) wrench is required.
2. Sighting the front face of the adjusting nut with the torque
meter lines on the nameplate indicates the approximate
torque setting.
4. The first line on the torque meter beyond “Min.” represents
the low torque setting.
NOTICE
The clutch should not be operated at torque settings
below this “Min. line or potential for equipment damage
could occur.
5. Do not set the torque if the clutch is disengaged as an
erroneous torque setting will result.
NOTICE
Do not remove the adjusting nut. Extremely fine
threads are used to reduce the possibility of the adjusting
nut losing its setting. If the adjusting nut is removed for any
reason, (including lubrication) upon replacing, hand thread the
first few turns or cross threading may occur.
The Torq/Gard clutch is delivered with the torque set at the low
end of its torque range.
Tripping torque can be established by progressively increasing the
torque setting until the clutch no longer trips under starting loads.
If the tripping torque value is known, the clutch may be pre-set
with a torque wrench or a torque arm and calibrated spring scale.
The Torq/Gard clutch may also be sized by applying one of the
following formulas:
Torque (In.-lbs.) = Horsepower (HP) x 63025 / RPM
OR Horsepower = Torque (In.-lbs.) x RPM / 63025
Tripping Torque = Operating Torque x Service Factor
NOTICE
The nameplate contains a sensitized “rectangle” on
which the torque setting may be recorded with ball point pen
or a numbering die to help ensure the correct torque setting
is applied for equipment protection.
WARNING!
The Torq/Gard clutch is not a fail-safe device
and cannot be used on “overhauling” or “holding” load
applications. Use of this product as a fail-safe device could
lead to death or serious injury.

Automatic Reset
The Torq/Gard clutch is automatically reset
by “jogging” the motor after the overload
has been corrected. At speeds under 50
rpm the Torq/Gard clutch will re-engage,
without jogging, upon starting the motor.
The clutch will not re-engage if the overload
exceeds the torque setting.
WARNING!
Do not re-engage the
Torq/Gard manually. When the
clutch snaps into engagement,
injury could occur if the operator’s
hand is near a chain and sprocket
or belt drive.
3. The “Min.” line on the nameplate is the point at which
the adjusting nut is threaded. Before setting the torque,
Permabond
®
HM118 should be applied to the exposed threads.
