High-torque fasteners on trucks, buses and heavy industrial equipment can be challenging to handle, particularly during roadside repairs and field maintenance. The Norbar HandTorque HT3 2700 Kit increases the output torque of a compatible 3/4" torque wrench, helping technicians work with fasteners that require up to 2,700 N·m.

The multiplier uses multi-stage epicyclic gearing to convert a lower input torque into a higher output torque. Its 5:1 torque multiplication ratio allows the operator to calculate the nominal input torque by dividing the required output torque by five. For example, a target output of 2,000 N·m requires a nominal input of 400 N·m, subject to the manufacturer's instructions and applicable operating limits.

The HT3 2700 Kit has a listed working range of 270–2,700 N·m. It accepts a 3/4" square drive torque wrench and delivers output through a 1" square drive. Its manual operation makes it suitable for workshops, roadside service vehicles, offshore facilities and remote industrial sites where powered equipment may be impractical or restricted.

The complete kit includes the Norbar HT3 2700 multiplier (Part No. 17219), two reaction bars, a reaction foot and a carry case. These components support practical setup and transport for demanding bolting applications. Always use the reaction components in accordance with the manufacturer's instructions and confirm that the setup is suitable for the application.

For applications requiring a lower maximum output, compare the Norbar HandTorque HT3 1300 Kit, Part No. 17220, to determine which capacity best matches your fasteners and available torque wrench.

Who This Product Is Best For

• Truck and bus maintenance workshops handling high-torque wheel fasteners.

• Heavy equipment service teams working with 1" drive fasteners up to 2,700 N·m.

• Roadside assistance and field maintenance technicians.

• Offshore, oil and gas and petrochemical facilities where powered tools may be restricted.

• Industrial maintenance teams that need a portable, manually operated torque multiplier.

How to Specify & Install It

1. Confirm the required output torque: Ensure the application falls within the listed 270–2,700 N·m working range.

2. Check drive compatibility: Verify that your torque wrench has a compatible 3/4" square drive and that the output socket suits the 1" square drive.

3. Calculate the input torque: Divide the target output torque by the stated 5:1 multiplication ratio, following the manufacturer's instructions.

4. Fit the multiplier: Connect the torque wrench to the input drive and fit the appropriate socket to the output drive.

5. Position the reaction components: Use the supplied reaction bar or reaction foot as directed by Norbar, ensuring a suitable, solid reaction point and keeping hands clear of pinch points.

6. Apply torque smoothly: Follow the manufacturer's operating procedure and do not exceed the rated limits of the multiplier, wrench or socket.

7. Verify the setup: Check secure engagement, correct operating direction and proper reaction support before applying load.

8. Store the kit safely: Inspect the components after use and return them to the carry case according to your maintenance procedures.
