Hydraulic Torque Wrench Setup Instructions
A hydraulic torque wrench is an industrial torque wrench capable of tightening bolts accurately up to 150,000 foot-pounds of torque. Hydraulic torque wrenches are lightweight and portable devices; however, they require the use of a 10,000-psi pump. Setting up your hydraulic torque wrench is a relatively straightforward process that requires you to hook the pump up to the wrench head and set the necessary torque value using the air pressure of the pump.
Instructions
- 1
Connect a male 10,000-psi hydraulic pump hose from the female connection on the torque wrench to the female connection on the 10,000-psi pump.
2Connect a female 10,000-psi hydraulic pump hose from the male connection on the torque wrench to the male connection on the 10,000-psi pump.
3Twist the metal connectors on both ends of each hose clockwise until secure.
4Connect the pump to an available power outlet if it is an electric pump or to an air-pressure source if it is an air-driven pump.
5Locate the desired torque value on your torque conversion chart. Scroll over to determine the corresponding hydraulic pressure value that you must set on the pump.
6Loosen the locking ring on the adjustable relief valve on the pump. Turn the thumbscrew clockwise to increase the amount of pressure the pump can contain or counterclockwise to decrease the amount of pressure the pump can contain.
7Press and hold the "Advance" button on the pump remote control to fill the pump until the pump gauge reaches the desired pressure.
8Tighten the locking ring on the adjustable relief valve once pressure is set to the desired level.
9Connect the desired impact socket to the torque wrench head and insert the locking pinion into the socket.
10Apply the torque wrench head to any bolt you wish to tighten, ensuring that the reaction arm (long portion of the torque wrench head) presses against an adjacent surface.
