How to repair an air compressor tank?

These instructions will give you an overview of how to repair your air compressor tank. The repairs are similar for other air compressor models, so feel free to follow along with the rest of this article. Turn off the power to your machine. Now remove the ATV or car hose from the tank and store it safely. Clean the tank and the entire area where you are working with a rag or paper towel. Now remove the cap and hose from the bottom of the tank. Make sure that you don’t spill any of the used parts while you are doing this.

If you do spill anything, make sure to clean it up immediately. After removing the bottom cap, you will see the air compressor tank. Look for any pieces of metal or other debris that may have collected in the tank. Clean these out if you can, as they may have caused damage to your machine.

Checking Your Compressor’s Condition

Before you take your compressor apart, you will want to make sure the machine is free of any issues that could contribute to the failure of your air compressor tank. – Is your compressor staying on? – Is it running? – Is the pressure in the tank at the correct level? – Is the oil level in the crankcase low? – If you can’t answer “yes” to at least one of these questions, it’s a good idea to have your compressor serviced.

In order to check your compressor’s condition, you will want to start by turning the machine on and placing a gauge on the air hose fitting of your air compressor. You will want to make sure the gauge is connected to the hose.

You will want to adjust the gauge to the level you normally operate at. The pressure of the air should stay constant, but if it drops, your compressor is at risk of failure. Once you have confirmed the level, you will want to shut the machine down and pull the gauge off the fitting.

Most Common Problems with Air Compressor Tanks

You may have done a thorough inspection of your air compressor, and you may be ready to repair your air compressor tank. However, you should be prepared for the tank to have a few issues.

Kalamazoo-Type Leak

This is the most common type of tank leak. If you notice odor or a puddle near your compressor, it’s likely that you have a kalamazoo-type leak. The good news is, this is one of the easiest types of leaks to repair.

Cracked Tank

A cracked tank may not have a leak, but it poses similar problems. If your tank has a crack, the pressure will drop significantly when the compressor is turned off. This is a common issue that can be repaired with a copper washer and copper nut.

Leaking Hose

A leaking hose is one that slowly lets air out over time. You can check for this type of leak by adjusting the pressure of the tank and checking for leaks on the hose. If you see any, you can repair it by replacing the rubber hose.
