With everything gathered up and ready to go, it’s time to move on to disassembling the AC compressor and preparing it for conversion into an air compressor.

Disassemble the AC Compressor

Now it’s time to take apart the system that circulates refrigerant and generates cool air, so you can access its internal components. Begin by removing any remaining refrigerant from the AC compressor. You can do this by unscrewing the valves or taking it to a professional who can safely remove the refrigerant.

Next, use a wrench to remove all bolts and screws holding the compressor together. Keep track of these small parts as you’ll need them later on. Once all bolts have been removed, gently separate each piece of the compressor until you’re left with just the main housing unit.

Be sure to inspect each component for any damage or wear and tear before proceeding with converting your AC compressor into an air compressor.

Now that your AC compressor has been disassembled, it’s time to prepare it for air use by cleaning and oiling its internal components.

Prepare the Compressor for Air

With the refrigerant removed and all bolts and screws unscrewed, let’s dig into the guts of this machine to give it new life as a powerful tool.

Before we can start using our AC compressor as an air compressor, we need to prepare it for the task at hand. The first step is to take off the clutch and pulley assembly from the compressor shaft. This can be done by either prying it off with a screwdriver or by using a puller tool.

Next, we need to remove the valve plate assembly from the compressor body. This will allow us to access the reed valves inside which must be removed before using compressed air instead of refrigerant gas. Be sure to keep track of any small pieces such as springs or metal plates that may come loose during disassembly.

Finally, we need to clean out any remaining oil or debris from inside the compressor body. This can be done with compressed air or by wiping down all surfaces with a clean rag. Once everything is cleaned and inspected for damage, our AC compressor is ready to be transformed into an efficient air compressor.

Now that our AC compressor has been prepared for its new role, it’s time to install an air tank so we can start putting it to use in various tasks around our workshop or garage.

Install the Air Tank

Ready to power up your tools? Let’s move onto the next step and attach a tank to our newly transformed machine.

To do this, you’ll need an air tank and some fittings. First, locate the pressure switch on your compressor and remove it. Then, screw in a tee fitting where the pressure switch was located. Attach a ball valve to one end of the tee fitting and a quick disconnect fitting to the other end.

Now it’s time to connect the air tank. Screw in another tee fitting onto the ball valve we just installed. Attach one end of an air hose onto this tee fitting and connect the other end to your air tank using a quick disconnect fitting. Make sure all connections are tight and secure before moving on.

Finally, close both valves so that no air can escape from either side of the system.

You’re now ready for reassembly! In the next section, we’ll go over how to put everything back together properly so that your newly transformed compressor is ready for use once again.

Reassemble the Compressor

Let’s put everything back together so that this machine is ready to power up your tools once again. Reassembling the compressor is a crucial step in converting an AC compressor into an air compressor.

Begin by placing the pulley onto the shaft and tightening it with a bolt.

Next, reattach the clutch using its original screws and connect the electrical wire to it as well. Make sure that you’ve connected all the wires correctly and securely before moving on to the next step.

Finally, attach the hoses to both ends of your newly installed tank and tighten them with clamps. You’re now ready to test your air compressor and see if it can deliver enough pressure for your tools!

With everything assembled correctly, we can move on to testing our new air compressor. But before you start testing, make sure that all connections are tight and secure.

Turn on your machine and let it run for a few minutes to ensure that there are no leaks or other issues. With these steps completed successfully, you’re now ready to put your new air compressor through its paces!

Test the Air Compressor

You’re about to see the power of your newly assembled machine as you put it through rigorous tests. Before testing, make sure that all connections are tight and secure.

Turn on the compressor and let it run for a few minutes to ensure that there are no leaks or unusual noises.
