https://www.norbar.com/

A torque multiplier is a tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other items design to be actuated by application of torque, such as the actuation of valves, particularly where there are relatively high torque requirement. Norbar Torque Tools, the world’s torque specialist, presents this simple video how to guide on how to use a torque multiplier. Using a torque multiplier and torque wrench with the correct method will ensure high accuracy bolt tightening, and by employing good reaction point practise will reduce the likelihood of equipment or parts breaking.

Before using a torque multiplier, it’s important to always read the instructions before use and ensure that you maintain the tool according to the advice provided. Refer to manual or specification in order to obtain the required torque. If the multiplication ratio is 25:1, this means you set the torque wrench to 1/25th of required torque. It’s essential that you never exceed the maximum input torque.

First, assemble socket, ‘O’ ring and retaining pin. Do not use an extra-long extension or socket and similarly do not use universal joints. Now, place multiplier on the fastener. A couple of checks to make when using a torque multiplier, first check the multiplier is rotating in the required direction and also check that the wrench is rotating in the required direction. Place on the multiplier

Choose a suitable reaction point — in this video you will see good and poor reaction points and the resulting pressure force from each, you’ll also see what happens when you use a poor reaction point. Now being to tighten and continue to tighten with the torque wrench and torque multiplier until you hear the click. The multiplier is now successfully and safely locked on.

Do not strike the anti wind-up ratchet. To realise the wind-up simply use the following sequence.
Replace the wrench on the torque multiplier. Load the torque wrench. Reverse direction of anti wind-up reaction. Ensure you release the wind-up in a safe and controlled manner.

There are many different styles and qualities of torque wrench available. With the correct selection, operation and maintenance, a torque wrench can save you time and money. To make the correct decisions you may need to seek the advice of specialist torque tool provider like Norbar Torque Tools.

A good tip, it’s so easy to gap a spark plug with a channel lock plier. Easy leverage control, fast and simple, you can open and close the gap easily. I gap my spark plugs visually, no need to measure.
