Model 8111-8112 Torque Multiplier
The Sweeney 8111 and 8112 Torque Multipliers provide maximum power for
breakaway and maximum speed for run-off of large threaded assemblies. Both operate
most effectively with Sweeney designed anchors and sockets that always “turn the nut”
and hold the “bolt.”
Design features of the
8111 and 8112 include:
• Splined output for maximum strength
• 360° continuous rotation both directions
• Dual input both sides
• Four speeds (when used with pneumatic drive)
• Manual or pneumatic operation
• Anti-backlash brake system
• 360° Rotatable Protractor
1. DESCRIPTION
1-1. The Sweeney Models 8111 and 8112 Torque
Multipliers are high ratio; triple reduction gear
mechanisms providing power multiplying means
for loosening and tightening threaded assemblies
that demand high torque values. Each model is
designed with an internal splined drive that
connects to sleeve sockets with are specially
designed for each application. Anchor pins are
located on each face of both models for
versatility of anchoring.
1-2. Because of the high gear ratios, each model is equipped with both a primary and secondary
input for convenience (secondary input on front
only).
Note: The primary and secondary inputs rotate
in opposite directions.
1-3. As a safety consideration, an automatic brake system prevents the output from turning the
input. (See section 3-2 for comments on brake
testing.)
2. CAUTIONS AND WARNINGS
2-1. Test automatic brake system prior to every use.
This automatic brake system prevents the
output from turning the input.
2-2. Use extreme caution when operating the Torque
Multiplier with faulty brakes. See Section 3-2.
2-3. Repair, overhaul, or calibration must be done by
the factory.
Do not disassemble the unit in the field.
3. OPERATION
3-1. Anchor Information. When using the 8111 and 8112 Torque Multipliers, a method must be
provided to react the torque being applied to the
threaded element. It is preferable to locate this
anchor near the threaded element. Whatever
means of anchoring is employed, the anchor must
mate to the anchor pins of the multiplier.
The anchor must be solid with minimum
deflection and designed to be perpendicular to
the axis of the threaded element to insure proper
alignment of the torque multiplier. The anchor
should be properly designed for each application.
Consult the Sweeney Division for design
information.

3-2. To test brake, torque the primary input to 80 ft- lbs with a torque wrench; then gently release. If
the torque wrench remains stationary, the brakes
are in good working order. If the wrench rotates
back at a moderate to fast rate, the torque
multiplier should be returned to the factory for
brake overhaul at the earliest opportunity. USE
EXTREME CAUTION WHEN OPERATING
THE TORQUE MULTIPLIER WITH FAULTY
BRAKES. This test should be conducted with
every use of the tool.
3-3. Optional Equipment: Additional smaller torque multipliers may be connected to either input to
reduce the required input torque to achieve high
output torques. Model 8202A Air Torque
Multiplier provides two speeds which, when
added to the primary and secondary input
option, result in four distinct torque ratios and
eliminate the need to react the input torque. Only
one mechanic is required when this tool is used
with the 8111 and 8112 Torque Multipliers.
The correct sequence in going from the highest
torque (slowest output speed) to the lowest torque
(Highest output speed) is:
A. Low speed output of Model 8202 to primary
input.
B. Low speed output of Model 8202 to secondary
input.
C. High speed output of Model 8202 to primary
output.
D. High speed output of Model 8202 to
secondary input.
Note: When changing from primary to secondary
inputs, the rotation of the 8202 output must be
reversed. Also, the high and low outputs of the
8202 rotate opposite of each other. Always check
the rotation of the output to be used before
mounting.
4. CALIBRATION
4-1. Each unit in field service should be calibrated
once every year by Sweeney factory personnel
and equipment. If unit is used on a continuous or
daily basis, this may dictate calibration every six
to nine months. To determine the proper
calibration cycle for a particular usage, consult
Sweeney, Denver, Colorado.
5. MAINTENANCE
5-1. Each torque multiplier is adequately lubricated
at the factory for normal service between
overhauls and/or calibration cycles. No additional
lubrication is required during field service.
5-2. Care should be exercised when using the tool to
protect it from external damage and corrosive
environments.
5-3. Inspect the torque multiplier and other optional
tools at each use for cracks in the housing
casings. These parts are subjected to a high
degree of stress when in use, no attempt should
be made to repair cracks or any damage which
has seriously weakened the structural integrity of
the part. Return to factory for part replacement.
Minor scratches burrs, or nicks may be removed
by a fine cut file or stone.
5-4. A unit in need of repair, overhaul or calibration MUST be returned to the factory. Any unit
disassembled will require recalibration. DO NOT
disassemble the unit in the field.
