The very first thing you will have to do is to disconnect the air compressor from the power source. This can be done by either unplugging it or turning off the breaker that is supplying power to it.

2. Remove The Pump Cover:

The pump cover is located on the top of the pump. There are usually several screws that hold it in place. Remove them with a screwdriver to take off the cover.

3. Disconnect The Hoses From The Pump:

4. Locate The Screws That Hold The Pump Together and Remove Them:

Now, locate all of the screws that hold the pump together. There are usually several on each side. Remove them with a screwdriver to take the pump apart.

5. Take The Pump Apart and Clean All The Parts:

Once you have removed all of the screws, take the pump apart. Be careful not to lose any of the small parts. Clean all of the parts with a brush or a rag until they are free of dirt and oil.

6. Replace Any Broken Parts, Including Seals, Bearings, Or Shafts:

If any of the parts are broken, replace them now. This might be seals, bearings, or shafts. Make sure that all of the parts are clean and free from debris before replacing them.

7. Reassemble The Pump With New Pparts If Necessary:

If any of the parts needed to be replaced, now is the time to reassemble everything. Make sure all of the screws are tightened so that they won’t come loose while operating the air compressor. If there were bearings or shafts that needed to be replaced, gather those as well as begin putting them back together.

8. Reconnect The Hoses And Reattach The Cover:

Once you have finished putting it back together, simply reconnect all of your hoses and attach/plug in your air compressor cover or top. Before you turn on your machine again, make sure to check all of the valves to make sure they are in the open position.

Things To Consider Before Rebuild The Air Compressor Pump

Here is a list of 10 things to consider before rebuilding your air compressor pump. They are very helpful for you to rebuild it without any problem.

1. Make Sure There Is No Pressure in The Tank:

Before taking parts out or opening up an air compressor, make sure that it isn’t charged with any pressure. If you open the valve and release any pressure that’s in the tank, it will relieve any built-up energy and make the job much safer.

2. Release The Pressure In The Tank:

Once you have relieved any pressure in the tank, it’s time to release the pressure that’s in the lines and valves as well. This can be done with a release valve on the compressor or by bleeding the lines.

3. Disconnect The Power:

Before doing anything else, always disconnect the power from the compressor. This will make sure that you won’t get injured by any moving parts or electricity.

4. Remove The Discharge Tubing:

It’s a good idea to remove all of the discharge tubing before taking off any parts, this way there isn’t anything restricting you should it be necessary to rotate the crankshaft.

5. Remove The Belt:

The next step is to remove the belt. You can do this by loosening the tensioner and sliding the belt off of the pulleys.

6. Remove The Compressor Head:

Now it’s time to remove the compressor head. This is usually held in place with several bolts. Be sure to remember where everything goes so you can put it back together correctly.

7. Remove The Valves:

Once the compressor head is off, you can remove the valves. This is done by loosening the retaining screws and pulling them out of the head.

8. Clean The Parts:

Once all of the parts are removed, it’s a good idea to clean them with an air hose. This way you can get rid of all of the debris that has accumulated on the parts. And have a good look at everything.

9. Inspect Parts:

While you have everything apart, now is a great time to inspect all of your parts. Start with the valves, which are usually made out of brass. Make sure that there is no damage to the surfaces and that the springs are in good condition.

10. Assemble The Compressor:

Once you have inspected and cleaned all of the parts, it’s time to reassemble the compressor. This is done in reverse order of how you took it apart. Be sure to pay close attention to all of the gaskets so you get a good seal when putting them back together.

Final Words

Rebuilding an air compressor pump can be a daunting task. But if you take it slow and follow these instructions carefully, you can do it! And once you’re finished, you’ll have a like-new pump to use on your air compressor. So if your machine is in need of some TLC, consider rebuilding the pump yourself.
