Why Is It Important To Oil An Impact Wrench?

The metal parts of the impact wrench get very hot during the work process. When a metal part gets hot, it expands. When an expansion happens, the wrench can start to lose its tightness. When you are using an impact wrench, the same thing happens. 

A few drops of oil will help keep the metal parts cool, which helps keep the wrench tight. An impact wrench needs to be oiled to keep it working properly. Without oil, it could become jammed or damaged.

How To Oil Impact Wrench Step By Step Process

Step 1: Remove The Impact Wrench’s Rubber Cover

Start by removing the rubber cover of the impact wrench properly. You can perform this process with proper care because the cover can be quite fragile.

Step: 2 Remove The Back Plate

Now, remove the back plating. You may also use a flat blade screwdriver to remove the back plate of the impact wrench.

Step 3: Take Out The Rod and Bearing

Once the back plate is out, you can remove the rod and bearing assembly. To do this, first, turn the handle in your direction. After that, slide the rod out of the wrench. It will be easier if you lubricate the threads first. Do not forget to check the gap between the rod and the housing. It would help if you could not slide the rod out of the housing.

Step 4: Pull out The Air motor

After removing the rod and the bearing from the housing, you will find an air motor inside. Inside the wrench, the air motor functions similarly to a vane or propeller motor. This air motor is composed of vanes that generate motor motions. Make care to clean and oil them when you disassemble them. After that, remove the air motor housing and the front bearings.

Step 5: Take Off the Hammer and Anvil

You can begin removing the hammer with the air side completely removed from the wrench. Start from the front and push the anvil, and hammer out together. Doing this will allow you to remove the hammer and anvil in one go. To separate the hammer from the anvil, you’ll need to remove the round gasket connecting them first. Unscrew it using a screwdriver, and then you should be able to tear it off.

Step 6: Start Cleaning

Once the anvil has been removed, start cleaning the parts. Clean up the oil and dirt using a wire brush. It’s a good idea to keep a rag nearby so that you can wipe down the parts before putting them back together.

Step 7: Reassemble

Next, you’ll need to put everything back together in the reverse order you took it apart. Give it your best shot and do it well the first time, or you’ll spend more time mending it later.

Step 8: Remove Oil Plug

You’ll need to remove the oil plug to remove the anvil. To do this, you’ll need to unscrew it. You can utilize a screwdriver to unscrew it. 

Step 9: Use Lubricating Oils

After removing the oil plug, make sure to lubricate your wrench parts properly with one or two drops of oil. This regular maintenance will help keep things from getting stuck and the parts working smoothly. 

Step 10: Put the Rubber Jacket Back On

Once you’ve lubricated properly the parts of impact wrench and replaced the oil plug, it’s time to put the rubber jacket back on. This is easily accomplished by sliding the jacket around the rods. It’s a smart idea to wipe up your wrench before you finish. To remove any extra oil or grease, use a wipe or towel. The proper oil would keep your tool internal components in right condition.
