Step-by-Step Guide to Fixing a Torque Wrench
Repairing your torque wrench involves systematic steps to identify and resolve issues. Follow this guide carefully, as improper repair may void warranties or worsen the damage.
Cease Using Your Torque Wrench Immediately
If your torque wrench isn’t functioning correctly, stop using it immediately. Continuing to use a faulty wrench risks damaging fasteners and compromising safety.
Identify Your Torque Wrench Type
Determine if you have a click-type torque wrench, beam torque wrench, or other variant. Each type has unique components, such as the lockout knob assembly in click-style wrenches.
Determine Your Torque Wrench Type
Inspect the wrench body, calibration sleeve, handle, and square drive for visible cracks, dents, or wear. Ensure that the pivot point and directional switch are intact and functioning.
Check for Cracks or Damage Overall
Inspect the wrench body, handle, and calibration sleeve for visible cracks, dents, or other signs of wear. Pay close attention to the square drive and pivot point, as these areas often bear the most stress. Examine the directional switch to ensure it operates smoothly without sticking.
Take Apart Your Torque Wrench
To access internal components, fully unscrew the calibration lock nut and remove the adjustment assembly. Take care to document the placement of parts like ball bearings, springs, and the retainer screw to ensure correct reassembly.
Test the Clicker Mechanism and Lockout Knob
Inspect the clicker mechanism and lockout knob assembly for wear:
Clicker Mechanism: Test the clicker to ensure it produces the expected sound and movement at the required torque. If not, check the spring and ball bearings for wear.
Lockout Knob: Verify that the lockout knob holds torque settings securely. Tighten it if loose or replace it if damaged.
Put Your Torque Wrench Back Together
Reassembly involves placing the components back in their original positions. Start by reinserting the spring, ball bearings, and pins into the wrench body, ensuring proper alignment. Secure the calibration sleeve and tighten the lock nut to hold the assembly in place. Verify that the directional switch moves smoothly and test the wrench at a basic torque setting to ensure proper function before full use.
Thoroughly Clean Your Torque Wrench
Wipe the wrench body, square drive, and ratchet head with a soft cloth to remove dirt and grease. For stubborn rust, use a rust remover and apply light lubricant to the socket, pins, and other moving parts. Avoid submerging the wrench in water, as this can damage internal components and lead to premature wear.
Perform a Recalibration of Your Torque Wrench
Fully unscrew the adjustment assembly to set the wrench to its lowest torque setting. Use a calibrated device, such as a torque tester available at an auto parts store, to compare the wrench’s output to the reading engraved on the calibration sleeve. If adjustments are needed, loosen the lock nut and adjust the spring tension until the wrench provides accurate results. Retighten the lock nut and test the wrench again at different settings. Alternatively, consider Force torque wrenches Singapore for tools with precise calibration straight out of the box.
Inspect the Ratchet Head for Wear
Inspect the pin holding the ratchet mechanism to ensure it is secure and undamaged. Check for wear or pits machined into the ratchet teeth, and replace the drive ratchet if the teeth are excessively worn. Test the fit of the socket onto the square drive, ensuring it is snug and secure without slipping.
