Why Is Your Hydraulic Torque Wrench Not Working and How to Fix It?
Common Reasons Why a Hydraulic Torque Wrench Won’t Rotate
Hydraulic torque wrenches are powerful and precise tools, but they can occasionally stop rotating due to improper usage or component wear.
If your hydraulic wrench fails to operate, identifying the root causes is essential for timely repair and continued productivity.
Main Causes of Wrench Rotation Failure
- The drive frame is stuck with the ratchet wheel
- The ratchet and pawl mechanism are jammed
- The return spring of the drive frame fails to reset
These issues usually occur due to improper operation, such as incomplete stroke cycles or overuse without maintenance.
Understanding the Root of the Malfunction
What Happens During Improper Operation
During normal operation of a hollow hydraulic Torque Wrench, when the right button on the remote is held, hydraulic oil enters and drives the shaft to rotate.
When the button is released, a “click” sound indicates proper calibration.
If the operator fails to wait for this "click" and releases the button prematurely, the cycle is interrupted, increasing the risk of ratchet locking or tooth jamming.
Over time, this may damage the internal mechanism.
Other Contributing Factors
- Worn-out pawl teeth or ratchet teeth
- Lack of timely system maintenance
- Hydraulic contamination or pressure anomalies
How to Fix a Hydraulic Torque Wrench That Won’t Turn
Step-by-Step Troubleshooting
- Use a fine triangular file to clean and sharpen the ratchet and pawl edges
- Adjust the return spring position to ensure proper resetting
- If parts like the drive frame or ratchet teeth are cracked or broken, replace them with OEM spare parts
- Immediately stop using the wrench if the Hydraulic System is unresponsive
- Consult a certified technician for complex repairs or diagnostics
Preventive Maintenance Tips
Regular inspection and lubrication of your hydraulic torque wrench can significantly reduce failure rates.
Ensure your team is trained to recognize early signs of malfunction, and avoid continuing operation when unusual behavior is observed.
