Makita MAC2400 Air Compressor Parts

MAC2400 is popular for its “Big Bore” cylinder and piston setup. It delivers solid output without needing to run at high RPMs, which helps keep the compressor quieter and more durable on tough job sites. However, even the most durable cast iron pumps need maintenance eventually. At DanseUSA, we offer genuine Makita MAC2400 air compressor parts, from internal pump components to external service items to help you repair leaks, rebuild the pump, or keep your unit performing reliably.

Parts Overview

Our collection covers the complete schematic for this 2.5 HP unit. Since the MAC2400 runs on an oil-lubricated system, good seals and proper lubrication really matter. We stock everything from small O-rings to motor windings, so you can get the right MAC2400 parts without guessing. Just use our part breakdowns to quickly match the exact screw, valve, or cover you need.

MAC2400 Air Compressor Assembly Parts

Most MAC2400 repairs start with the main assembly diagram, which covers the motor/pump housing and the tank. Below are the essential Makita MAC2400 air compressor parts commonly needed for bigger fixes:

  • Pump internals: The core moving parts - like the piston, cylinder, and connecting rod - that do the actual compressing.

  • Head + valve parts: Components like the cylinder head, gaskets, and valve plate that help the pump seal properly and build pressure.

  • Cooling + motor parts: Items such as the motor fan and related hardware that keep the motor running cooler and smoother.

  • Control components: Pressure switches, regulators, and discharge tubes that control airflow from the tank to your tools.

FAQs

What type of oil should I use for the MAC2400?

The MAC2400 uses an oil-lubricated pump, so it requires regular non-detergent air compressor oil. Makita’s recommended option is 181122-A (181122A) Compressor Oil, 1 Quart, which is for the Makita MAC2400. If you’ve replaced internal parts like the piston or connecting rod, do a full oil change before putting the compressor back into service.

Why is my MAC2400 leaking air when it shuts off?

This is often caused by a faulty check valve or a worn tank drain valve. When the check valve fails, back pressure from the tank can leak through the unloader valve. Replacing the affected part usually resolves the issue.

Do you sell the air filter element separately?

Yes. A clogged air filter can reduce performance and make the compressor run louder. We carry the 171006-E (171006E) Air Filter Element for the Makita MAC2400, so you can replace it and keep the intake clean and airflow consistent.
