OPERATION AND MAINTENANCE MANUAL
FOR TX 2, 4, 8, 16, 32
LOW PROFILE HYDRAULIC TORQUE WRENCHES
Series TX-2, TX-4, TX-8, TX-16 and TX-32 Low Profile Hydraulic Torque Wrenches are designed for
installing and removing large bolts having minimal wrench clearance at offshore platforms, power
plants, steel erection sites and other locations requiring precise high torque during bolt makeup and
maximum torque for bolt breakdown.
Aztec Bolting Services is not responsible for customer modification of tools for applications on which
Aztec Bolting Services was not consulted.
IMPORTANT SAFETY INFORMATION ENCLOSED.
READ THIS MANUAL BEFORE OPERATING TOOL.
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION IN THIS
MANUAL INTO THE HANDS OF THE OPERATOR.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY
.
PLACING TOOL IN SERVICE
•
Use the quick connect system to attach the hoses to the
tool and pump. Make certain the spring-loaded retaining
rings are fully engaged and the safety rings are tightly
threaded against the spring-loaded retaining rings to
prevent the connectors from disengaging under pressure.
When connecting hoses that have not been preloaded
with hydraulic oil, make certain the pump reservoir is
not drained of oil during start-up.
• Always operate, inspect and maintain this tool in
accordance with American National Standards Safety
Code for Hydraulic Rams and Jacks (ANSI B30.1)
• This tool will function using an air or electric powered
hydraulic pump. Adhere to the pump safety
requirements and follow instructions when connecting
the pump to the tool.
•
•
•
• Use only equipment rated for the same pressure and
torque.
Do not remove any labels. Replace any damaged labels.
USING THE TOOL
• Use only a hydraulic pump capable of generating
10,000 psig (681 bar) maximum pressure with this tool.
• Use only twin line hydraulic hose rated for 10,000 psig
(681 bar) pressure with this tool.
Do not handle pressurized hoses. Escaping oil under
pressure can penetrate the skin, causing serious injury. If
oil is injected under the skin, see a doctor immediately.
Never pressurize uncoupled couplers. Only use
hydraulic equipment in a coupled system.
Always wear eye protection when operating or
performing maintenance on this tool..
•
•
•
• Do not interchange the male and female swivel inlets
on the tool or the connections on one end of the hose.
Reversing the inlets will reverse the power stroke cycle
and may damage the tool.
• Do not use damaged, frayed or deteriorated hoses and
fittings. Make certain there are no cracks, splits or
leaks in the hoses.
Always wear head and hand protection and protective
clothing when operating this tool.
The use of other than genuine replacement parts may result in safety hazards, decreased tool performance, and
increased maintenance, and may invalidate all warranties.
Repairs should be made only by authorized personnel. Refer all communications to Aztec Bolting Services

PLACING THE TOOL IN SERVICE
NOT allow the tool to react against the hoses, swivels,
or inlets.
ADJUSTMENTS
3. After having turned the Pump on and presetting the
pressure for the correct torque, depress the remote
control button to advance the Piston Assembly. If the
notch in the piston rod did not engage the Retract Pin in
the Ratchet Link when the Link was joined to the
Housing, it will engage the Pin automatically during the
first advance stroke.
SETTING THE TORQUE
After determining the desired torque, use the torque con-
version chart on the Shroud or the torque conversion
charts on pages 5 and 6 to determine the pressure that is
necessary to achieve that torque.
1. Connect the tool to the power supply and turn the
pump on.
4. When the Link is connected to the Housing and the
wrench is started, the reaction surface of the wrench will
move against the contact point and the nut will begin to
turn.
2. Depress the remote control button causing the
pressure to be shown on the gauge.
3. Adjust the pressure by loosening the wing nut that
locks the pressure adjustment thumbscrew. Rotate the
thumbscrew clockwise to increase the pressure and
counterclockwise to decrease the pressure. When
decreasing pressure, always lower the pressure below the
desired point and then bring the gauge back up to the
desired pressure.
4.When the desired pressure is reached, retighten the
wing nut and cycle the tool again to confirm that the
desired pressure setting has been obtained.
5. When the nut is no longer turning and the Pump
Gauge reaches the preset pressure, release the remote
control button. The piston rod will retract when the
button is released and under normal conditions, an
audible “click” will be heard as the tool resets itself.
6. Continue to cycle the tool until it “stalls” and the
preset psi/torque has been attained.
7. Once the nut stops rotating, cycle the tool one last
time to achieve total torque.
OPERATING THE WRENCH
LUBRICATION
Wrench Positions
Dwg. 2
Marine Grade Moly Lube
Lubrication frequency is dependent on factors known
only to the user. The amount of contaminants in the
work area is one factor. Tools used in a clean room
environment will obviously require less service than a
tool used out-doors and dropped in loose dirt or sand.
Marine Grade Moly Lube is formulated not to wash out
of the tool in areas where lubrication is critical.
Whenever lubrication is required, lubricate as follows:
1. Separate the Low Profile Driver Assembly from the
Ratchet Link if they are joined.
SHROUD
TIGHTEN
LOOSEN
2. After wiping of the old grease, apply a daub of Marine
Grade Moly Lube to the hooking notch in the Piston
rod and wipe a film of Moly Lube onto the sides and
faces of the two Sliders.
REACT BETWEEN THESE POINTS
3. Disassemble the Ratchet Link as instructed in the
Maintenance Section and wash the components in a
suitable cleaning solution in a well-ventilated area.
4. Dry the components, then wipe a film of Marine
Grade Moly Lube onto the wear surface of both Side
Plate Sleeves and the hubs of the Ratchet.
The position of the tool relative to the nut determines
whether the action will tighten or loosen the nut. (Refer
to Dwg. 2 for application examples). The power stroke
of the Piston Assembly will always turn the Ratchet Hex
toward the Shroud.1.Place the Ratchet Hex on the nut.
Make certain it is the correct size for the nut and that it
fully engages the nut.
5. Spread a light film of Marine Grade Moly Lube onto
the inner faces of both Side Plates covering the area
where the Drive and Segment Pawl travel. DO NOT
pack the teeth of the Segment Pawl or Ratchet with
lube. It can prevent the teeth from engaging properly.
6. Reassemble the Ratchet Link as instructed in the
Maintenance Section.
2. Position the reaction surface against an adjacent nut,
flange or solid system component. Make certain that
there is clearance for the hoses, swivels, or inlets. DO
