A torque wrench is very similar to a conventional ratchet wrench. Today we are going to share a complete guide of how to use a torque wrench. The torque wrench is special for its tightening torque. That usually recorded next to the screw or indicated in the instructions. It is essential to apply just the torque recommended by the manufacturer of the component.
For this, you need a torque wrench with which you will provide the appropriate torque measurable units. The measurable different units are Nm the most used, in-lb, ft-lb and kg-cm. In this article, we will try to help to know how to use a torque wrench that great unknown to many.

How to Use a torque wrench: Easy Steps
This key has the peculiarity of serving to adjust the tightening torque of any screw or nut. The tightening torque of each screw or nut depends on its function, the length of the screw and its diameter. In the workshop manual, you can find out what is the torque for each screw or nut.
Normally it is long, at least 50 cm, to be able to do more advantage and with more precision. It is best to choose a key with the full range of torque, from 0 to 210 Nm. It is important to include the guarantee and approval stamps.
To avoid the tightening torques you must know about how to use a torque wrench because it’s very important for tighten the screws alternately. First, tighten them by hand with a wrench more manageable than the dynamometer, until you find a resistance. Then tighten a half turn with the torque to the right torque and then another. So on until the key warns you that you have reached the desired torque on all the screws.
Keep in mind that you do not need tightening torque greater than 50 Nm. Do not forget to leave the tightening torque setting to a minimum once you finish using the tool. So the inner spring will not deform and will continue to work perfectly for many years.
The Tightening Torque To Use Torque Wrench
It is the exact measurement of torque or tightening that we need to give to the engine parts and any other fundamental part. The torque of a tightening torque force is a unit of force for a turning distance. It comes expressed in two basic units:
- Nm Newton meter
- kgf.m kilogram-force meter
Turn the handle until you screw the key in the position you want to tighten. In this case 4.3Kg or 43 Nm. Most of the screws of the motorcycle being small are tightened to 20-40 Nm. There are two types of tightening torque, dry and wet. The difference is if the thread is lubricated or not, most are dry. Always wet will be greater so that the thread does not slip.

Example of tightening
The first thing you need to know to tighten screw/nut torque limitation then tightened to the desired torque. The example for a 1/2 " torque wrench with extension, elbow swing, 3/8" reducer and 8 mm Allen wrench to tighten the gearbox screw to 43-Nm.
It is always tightened cold due to the expansion of the hot materials. When the key suggest makes, pair clacks at that moment you must stop. If you continue to raise par it is important to make the continuous signal at the time of tight. So you have to use turns and elbows where we do not allow the complete turn of the key. In cases of non-use for a long time, it is advisable to store it with the minimum possible torque, turning the cuff against the hands of the clock until the stop.
The manuals show you how to assemble and disassemble each piece of your devices. In manuals, you can also find the necessary specifications for each thing, including the torque required for each nut or screw.
Most Common Tightening Torques: You should know To Use Torque Wrench
The Importance Of Torque Meter For Using A Torque Wrench
It is a precision tool helps us to adjust the torque of each screw of our machineries. It is not about tightening up to where our strength endures. Each piece must have a special Tightening torque according to its operation. If you plan to adjust your device, you should consider this tool to avoid problems in the short or long term. Let's see a video review of ChrisFix about how to use a torque wrench from youtube here now.
Great Instructions For How To Use A Torque Wrench
We hope that we could created a complete and proper guide of how to use a torque wrench. The importance of the tightening torque is such that if we do not have the screw or nut at its torque.
It will end up releasing the vibrations and if we tighten it too much it can burst a joint. The time of dedication to the tightening of the screws is high. For that, a reason it is almost impossible to have all the models and pairs for each motorcycle. That is why in the workshops these tasks are not carried out correctly.
A responsible use of this tool will give us a lot of security in the mechanics of our motorcycle.
