Main Parts of Craftsman Pancake Air Compressors
1. Pump Assembly
The pump is the heart of the air compressor, responsible for compressing air and storing it in the tank. Craftsman pancake compressors often feature a single-stage pump designed for light to moderate tasks.
Components of the pump include:
- Cylinder
- Piston
- Connecting rod
- Valves (intake and discharge)
- Oil lubrication system (if applicable)
Common issues related to the pump:
- Excessive noise
- Oil leaks
- Reduced pressure output
- Excessive vibration
Replacement parts include:
- Pump head
- Piston rings
- Valves
- Connecting rods
Proper maintenance, including regular oil changes and inspection, is key to prolonging the life of the pump.

2. Tank
The tank stores compressed air and is usually made from durable steel. Its size varies, with common capacities ranging from 1 to 6 gallons.
Important parts of the tank include:
- Drain valve
- Pressure relief valve
- Tank pressure gauge
Maintenance tips:
- Regularly drain accumulated moisture to prevent rust
- Inspect for corrosion or leaks
- Ensure safety valves are functioning properly

3. Pressure Switch
The pressure switch controls the activation and deactivation of the motor based on tank pressure. It ensures that the compressor maintains a set pressure range, preventing over-pressurization.
Key functions:
- Turning the motor on when pressure drops below the cut-in point
- Turning the motor off when pressure reaches the cut-out point
Common issues:
- Failure to turn on or off
- Inconsistent pressure regulation
Parts involved:
- Switch mechanism
- Pressure adjustment screw
Replacing or repairing the pressure switch can restore proper operation.

4. Regulator and Gauges
The regulator controls the output pressure delivered to connected tools, while gauges display tank pressure and regulated pressure.
Parts include:
- Regulator knob
- Pressure gauges
- Outlet ports
Maintenance tips:
- Keep gauges clean and calibrated
- Replace faulty regulators to ensure accurate pressure control

5. Safety Valve
A crucial safety component designed to release excess pressure if the tank pressure exceeds safe levels. It prevents potential tank rupture or explosions.
Common issues:
- Sticking open or closed
- Leaking
Replacement:
- Ensure you use a safety valve compatible with your compressor’s specifications
