How to use a torque wrench?
A torque wrench is a specially designed tool to tighten the nuts and bolts accurately to specific levels. This is used to work on bikes and cars universally. Torque wrenches can be adjusted by hand, and you don’t need any tool for that. You need to adjust it to a specific torque level. You can lock it in place using a tightener. After tightening it, fit it over the socket, bolt, or nut and move it clockwise. When done, you can turn the settings on the handle back to 0 and then store it. It would help to calibrate the torque at least once a year to ensure that the hash marks are accurate.
Torque is very precise equipment, and you should follow these four tips to handle them:- do not drop it, never use them like johnson bar for loosening the screws, it should always be kept clean, and last but not least, it should be returned to the lowest torque range.
- The first step is to set the torque wrench, form the lock that needs to disengage, and slowly rotate the handle and line up on the scale correctly. You can also set single value increments; you will need a scale around the handle. You will have to align the number scale on the handle along the centerline to the barrel. Therefore when you need 100-foot pounds, the number line on the handle should be zero. If it were 105-foot pounds, you would align the number to 5. Then make sure the lock is tight, or else you will risk the adjustment settings when fastening the torquing. Hold the pivot and then the other hand on the handle with one hand. Keep rotating the torque wrench until you hear a click sound, feel it, or see it. As soon as you notice the click activate, stop turning the wrench immediately. You need one click, or there is a risk of over-tightening this fastener.
- Then there is another method for using a torque wrench. It also follows the same principle: to pull back the lock, rotate the handle properly, and then release it to lock it into place automatically. You will have to lock every bolt to 20-foot pounds to do this. However, this inch-pound torque does not have a reading for foot-pounds, so we need to do a conversion. One foot equals 12 inches; therefore, 20 multiplied by 12 will be 240 inches. For instance, when setting it to 230-inch pounds, you must align it to 0 on the handle. When you need a valve above 240 inch-pound, you will have to pass the mark of 230 and l=align the handle to 1oth increments. Keep one hand on the pivot point and the other hand on the handle, and then rotate it until you hear that click sound and only one click is needed. When you have done this, position the value scale to the lowest position to avoid jeopardizing the accuracy of the torque values.
