What Happens During a Torque Wrench Repair Service?

A Step-by-Step Look Inside the Process

If your torque wrench isn't clicking quite right or seems to be delivering inconsistent torque, it may be time for a professional repair. But what actually happens when you hand your tool over to a repair shop? Torque wrench repair is a technical, quality-driven process that goes far beyond a simple tune-up. Here’s a detailed look at each step professionals take to restore your torque wrench to factory-level accuracy.

1. Inspection & Testing

Before any tools are opened or repaired, technicians begin with a thorough inspection.

What this involves:

• Visual assessment: They check for obvious wear, damage, or contamination on the handle, head, scale window, and drive.

• Functional testing: The wrench is tested on a calibrated torque tester to check whether it clicks or signals at the correct torque settings.

• Cycle check: They may simulate a range of torque cycles to look for signs of mechanical inconsistency, slipping, or failure to click.

Purpose:
This initial step determines whether your wrench is just out of calibration, has internal damage, or needs replacement parts. It's also used to document the “as found” condition—important for comparing before and after calibration results.

2. Disassembly & Internal Cleaning

Next, the torque wrench is carefully disassembled to access its internal components.

What this includes:

• Removing the handle to expose internal mechanisms for inspection

• Inspecting for internal wear such as scoring, corrosion, or seized/broken parts

• Examining the head kit for any rounded, chipped, or worn gear teeth that could cause slipping or skipping during use

• Cleaning out old grease, metal shavings, rust, or debris that could affect performance

Why it matters:
Over time, internal friction or contamination can drastically impact torque accuracy. Clean, well-lubricated internals are essential for reliable tool performance.

3. Component Replacement (If Needed)

During inspection or disassembly, technicians may find worn or broken parts.

Commonly replaced parts include:

• Tension springs (loss of accuracy or tension critical)

• Head-kits (worn or chipped teeth)

• Handle & Locking Mechanism (grip cracked or lock won’t hold setting)

• Torque Scale & Indicator (cracked or cloudy)

Tip:
Some repair shops stock OEM parts (original manufacturer parts), while others use high-grade aftermarket components. Be sure to ask about the parts used in your repair if long-term reliability matters to you.

4. Reassembly & Recalibration

Once cleaned and repaired, the tool is reassembled and recalibrated using certified equipment.

Recalibration process:

• The wrench is mounted on a torque tester or calibration bench.

• Torque values are tested at multiple points — typically at 20%, 40%, 60%, 80% and 100% of the tool’s rated capacity.

• Adjustments are made to bring the wrench back within tolerance — usually ±4% for click-type wrenches, per ISO 6789 or ASME standards.

Digital wrenches:
These are calibrated using electronic analyzers and may also require firmware checks or battery replacements.

5. Calibration Certificate & Documentation

Once recalibrated, the wrench is documented and certified.

What’s included:

• A calibration certificate showing:

  • Torque Tester Model & Identification

  • Calibration Lab Name

  • Tool serial number

  • Date of Calibration

  • Measured Torque Readings

  • Technician’s ID or signature

• Calibration sticker applied to the tool, showing next due date

Why this matters:
If you work in regulated industries like automotive repair, aerospace, or manufacturing, this documentation is often required for compliance and quality assurance.

Bonus: Turnaround Time & Cost Expectations

Most reputable torque wrench repair shops offer:

• Turnaround time: 3–5 business days (Rush service: Same-day or next-day service may be available upon request)

• Cost: Ranges from $100-350, depending on the wrench type and parts needed

• Warranty: Some shops provide a short warranty period or satisfaction guarantee
