Troubleshooting Problems with a Hydraulic Torque Wrench

A hydraulic torque wrench is a valuable and time saving tool in any garage or shop. The hydraulic torque wrench effortlessly combines hydraulic power with the precision of a torque wrench, efficiently and accurately tightening just about any fastener needed.

Frequently, hydraulic torque wrenches are used in auto body and mechanic shops, but are also used in manufacturing and fabrication. A hydraulic torque wrench requires a connection to a hydraulic power pack via a hydraulic hose. The proper settings are made, and with the touch of a button, the fastener is either tightened or loosened using the force of the hydraulics. This is a tool that really does do the work for you.

Here you will find some tips on troubleshooting problems with a hydraulic torque wrench.

Check Connections

If the connections between the wrench, the hose and the hydraulic power pack are compromised or not 100 percent connected, the wrench will not work properly. The hydraulic torque wrench's performance relies heavily on proper connections between all three components, as the power pack supplies the power, and the hose is what gets it there. If there is not a secure connection, this will result in poor operation of the wrench, or it not operating at all. If it is not performing as it should, double and triple check all connections to ensure they are secure.

Add Fluid

If the hydraulic fluid is low or is gone, this can also result in the torque wrench being underpowered or not operating at all. Refilling hydraulic fluid may be all that is needed. Check your fluid levels to ensure that this is not the problem. If needed, add more fluid.

Check Settings

Generally speaking, machinery does what you tell it to. Check your settings to ensure that they are set correctly if the torque wrench is not operating as it should. This may be all that is needed to correct the problem. Make sure that you are familiar with the operating instructions, and that you are familiar with the equipment.

Check Hoses

Check to make sure that any hydraulic hoses are not crimped or otherwise compromised. The hose can easily get trapped under a wheel or crimped around a corner, impairing the function of the tool. Also inspect the hose to make sure there are no holes or cracks, as the hydraulic fluid pressure needs to be maintained at the proper level in order for the tool to operate optimally.

Check Compatibility

If this is the first use of the torque wrench, hydraulic power pack, and the hoses, you will want to double check to ensure that all three are compatible with one another. If the hose is incompatible with the power pack, this will result in problems. Additionally, the hose will need to be compatible with the torque wrench. If you are purchasing the equipment, it is helpful to get all components from the same manufacturer to ensure proper operation.
