MAC5501G Makita Air Compressor Parts

The Makita MAC5501G isn’t your regular shop compressor. It’s a 5.5 HP gas-powered air compressor, built for those job sites where there’s no electricity and no time to waste. If you’re framing or roofing all day, this is the kind of unit you want,  a rugged cast iron pump, a reliable gas engine, and enough output to keep up with real work.

But here’s the thing with gas compressors: you’re maintaining two systems at the same time.
 You’ve got the pneumatic side (tanks, pressure, valves, pump parts) and the engine side (fuel, ignition, starter, air filter). If either one starts acting up, the whole unit slows down.

That’s why DanseUSA stocks genuine MAC5501G Makita Air Compressor Parts - so you can fix what’s wrong and get back to work without patchwork solutions.

Parts Overview

With the MAC5501G, repairs can be simple or serious. Sometimes it’s just a quick tune-up. Other times it’s a deeper rebuild. Either way, the right part matters.

Our catalog follows the full schematic for Makita MAC5501G Air Compressors, so you can match the part number from the diagram and order what fits your exact unit. We stock everything from small service items to complete assembly replacements.

MAC5501G Air Cleaner Assembly Parts

Gas engines hate dust. A clogged or damaged air cleaner can make the compressor feel weak, run hotter, and burn more fuel than it should.

If your MAC5501G is losing power or acting “off,” this is one of the first places to check. We carry genuine filter elements and covers so the engine can breathe properly again.

MAC5501G Compressor Assembly Parts

This is the air side of the machine - tanks, pressure controls, and the parts that manage airflow. If the engine runs fine but the compressor isn’t building pressure (or won’t hold it), this is where you want to look.

Common parts here include the pilot unloader valve, pressure gauge, and drain cocks that help keep operation safe and consistent.

MAC5501G Camshaft Assembly Parts

If you’re doing a full engine rebuild, the camshaft matters. It controls valve timing, and if timing is off, the engine won’t perform correctly under load.

We carry genuine camshaft assemblies so the engine stays properly timed and runs the way it should.

MAC5501G Carburetor Assembly Parts

Hard starting, rough idle, stalling - most of the time, it’s fuel-related. The carburetor is one of the most common problem areas on any gas-driven equipment.

We stock complete carburetor assemblies and gaskets for the MAC5501G, so you can restore the correct fuel-air mixture and get clean, stable running again.

MAC5501G Control Assembly Parts

If the compressor RPM keeps changing or doesn’t stay steady during cycling, the control assembly is worth checking.

This section includes throttle control springs, governor levers, and linkages - the small parts that make a big difference when you want smooth, steady RPM.

MAC5501G Crankcase Cover Assembly Parts

The crankcase cover protects the internal gears and supports the oil seal. If you’ve got oil leaks, cracks, or damage around that area, replacing the cover and gaskets is usually the right move.

We carry the replacement cover and the seals needed to close it up properly.

MAC5501G Crankshaft Assembly Parts

The crankshaft is the engine’s workhorse. It converts piston motion into rotation, and it takes serious stress when the compressor runs for long hours.

We stock precision crankshaft assemblies designed to handle continuous job site use and keep the engine running smoothly.

MAC5501G Cylinder Barrel Assembly Parts

If the engine has low compression, scoring, or heavy wear, the cylinder bore is often the issue. On the Honda GX160, the cylinder is part of the main block assembly. We carry the genuine piston kits, rings, and gasket sets needed to restore compression and power to a tired engine.

MAC5501G Cylinder Head Assembly Parts

The cylinder head assembly includes the valves, rocker arms, and the head casting itself. If you’re hearing valve noise, losing compression, or dealing with overheating, the head assembly may be the fix.

We carry complete cylinder head assemblies to solve those deeper engine problems properly.

MAC5501G Fan Cover Assembly Parts

Cooling isn’t optional on gas units. The fan cover helps direct airflow over the cooling fins and protects the flywheel area.

If the cover is broken or missing, overheating becomes much more likely - especially during long run times. Replacing it is a small fix that prevents bigger problems.

MAC5501G Flywheel Assembly Parts

The flywheel keeps the engine spinning smoothly and often includes the ignition magnets. If it’s damaged, you can end up with rough operation or ignition issues.

We stock balanced flywheel assemblies to keep rotation smooth and spark consistent.

MAC5501G Fuel Tank Assembly Parts

A leaking fuel tank is dangerous. No shortcuts here.

We provide complete fuel tank assemblies, including the cap and strainer, so you can keep fuel delivery safe and steady.

MAC5501G Ignition Coil Assembly Parts

No spark or weak spark? The ignition coil is usually the first suspect.

We stock ignition coil assemblies that help your MAC5501G fire up reliably and run without random shutdowns.

MAC5501G Muffler Assembly Parts

A working muffler isn’t just about noise. It also helps direct exhaust away from the operator and keeps the job site safer.

We carry muffler assemblies that help keep the compressor compliant and easier to work around.

MAC5501G Piston Assembly Parts

If the engine is smoking, feels weak, or won’t hold compression, the piston and rings may be worn.

We stock complete piston assemblies, including rings and wrist pins, so you can rebuild the top end properly.

MAC5501G Pump Assembly Parts

The pump is the heart of the pneumatic system. This section includes the “Big Bore” cast iron cylinder, head, and valve plates.

If your recovery time is getting slow, replacing the pump assembly is one of the fastest ways to bring performance back.

MAC5501G Recoil Starter Assembly Parts

When the recoil starter fails, the whole compressor is basically stuck. If the rope breaks or the spring gives out, you need a replacement that fits right away.

We sell the complete recoil starter assembly so it’s a quick swap and you’re back in business.

MAC5501G Engine Assembly Parts

This section covers the mounting and structural parts that connect the engine to the compressor frame. If you’re rebuilding or replacing major components, these parts help keep everything aligned and secure.

FAQs

What type of oil does the MAC5501G use?

This unit has two separate oil reservoirs: one for the gas engine and one for the air pump. The engine typically requires 10W-30 motor oil, while the compressor pump requires non-detergent air compressor oil. Always check your manual and use genuine MAC5501G Makita Air Compressor Parts for filters and plugs during maintenance.

Why is my recoil starter hard to pull?

This can be caused by a jammed recoil mechanism or internal engine resistance. Check the Recoil Starter Assembly in the parts diagram. If the rope is frayed or the spring is broken, replacing the full recoil starter assembly is usually the quickest fix.

My engine runs but the compressor won’t build pressure. Why?

This is often an issue with the Pilot Valve or the Drive Belt (V-Belt). If the belt is slipping, the pump won’t turn fast enough. If the pilot valve is stuck open, the compressor will vent air instead of filling the tank. Check the Compressor Assembly section for these parts.
