How to lubricate your impact wrench

impact-wrench-1

You can’t have an impact wrench without knowing you need to take care of it, no matter how performant or long lasting it might appear. As a matter of fact, any impact wrench might get water and debris buildup, just like any other tool. Despite the common opinion, draining the air tank in your compressor from time to time is not enough. This action simply keeps the rust away from the tank and doesn’t really protect the air tool from water.

You need to take consideration the risks of water contamination and condensation in the air line just as well as they might shorten the life span of your impact wrench. It doesn’t take much time nor effort to maintain your impact wrench lubricated and taking care of it on regular basic improves the efficiency of the tool.

Getting into the details

The impact wrench has a motor with machine polished surfaces, just like cylinders in car’s engine. There are many contaminants (water, dirt, dust and so on) that might destroy these surfaces and put the life of the motor to an end. Professional experts talk about how you should drain and purge the whole air system from the compressor to the tools once a week.

In order to expand the life span of your impact wrench, you could also avoid connecting a worn or a dirty hose coupler to your tool. Since couplers spend a lot of time on the floor, it’s only natural that they get dusty, dirty and these contaminants get easily, directly into your motor. It’s better to always use an air hose real suspended from your shop ceiling to have the hose and couplers off the floor.

Experts advice also tell us that you should lubricate the impact wrench three times a day: in the morning, in the afternoon and at night. It might seem awkward for some to lubricate the impact wrench at night, but this lubrication actually keeps condensation away and, therefore, rust.

As modern motors come with a gap between the air rotor and the motor itself, Lubrication doesn’t just minimize friction and protects against water condensation, but it also protects against air loss.

The main tips

There are some important steps you need to consider when you lubricate your impact wrench. Each one of these steps is essential in doing the lubrication efficiently.

First of all, you need to lubricate the mechanism on both ends of the tool. Keep in mind that many air tools feature several grease fittings and you better check the manual (or ask your dealer) if you don’ know exactly where they are placed.

Another thing to keep in mind is to only use the cleaner and grease recommended by the manufacturer for your impact wrench.

If you want to expand the life of your impact wrench, you should also install and maintain an in-line combination Air Filter/Lubricator/Regulator system. This system is supposed to clean and lubricate the air travelling through the air delivery system. This type of lubricator only works on your lines, fittings and hoses and doesn’t replace the daily oiling of the air tools.

In case you own a composite compact, you may use a needle grease gun on the body of the tool.

Impacts with aluminum bodies feature a pressure feed lubrication system and a fitting placed on the back of the wool. This mechanical system makes the oil from a separate reservoir go into the crankcase to lubricate the internal components.

The conclusion

If you want your impact wrench to last, you need to lubricate it and take good care of it. You also need to clean and store it after every use. A dry, enclosed space is the best choice for your impact wrench to store when not in use.

Of course you need some time and effort to keep your impact wrench in good shape, but this way you keep water and contaminants away from your tool.

You can’t get the best performance and efficiency from your impact wrench if you don’t lubricate it constantly. It’s only a matter of time for the internal components of the impact wrench to wear out if the tool is used if it’s not oiled enough.

The impact wrench doesn’t lockup, stall if is well lubricated and gives its best performance for longer time.
