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.
