Knowing these parts helps when troubleshooting or seeking replacements.
Key Sears Craftsman Air Compressor Parts and Their Functions
1. Compressor Pump
The pump is the heart of any air compressor, responsible for drawing in air and compressing it. Craftsman models typically feature reciprocating piston pumps or rotary screw pumps.
- Common issues: Leaks, loss of pressure, or excessive noise.
- Replacement tips: Ensure compatibility with your specific model. Look for OEM (Original Equipment Manufacturer) parts for durability.
2. Motor
The motor powers the pump, converting electrical energy into mechanical motion.
- Common issues: Motor failure, overheating, or electrical faults.
- Replacement tips: Check voltage and horsepower ratings to match the original motor.
3. Air Tank
The tank stores compressed air until it is needed. It must be free of rust and leaks for safety and efficiency.
- Common issues: Corrosion, leaks, or pressure loss.
- Replacement tips: Use tanks rated for your compressor’s maximum pressure.
4. Pressure Switch
This component automatically turns the motor on or off based on preset pressure levels.
- Common issues: Failure to activate/deactivate, causing over-pressurization or insufficient pressure.
- Replacement tips: Select switches compatible with your compressor’s pressure range.
5. Safety Relief Valve
A critical safety component that releases excess pressure to prevent tank rupture.
- Common issues: Sticking or failure to open.
- Replacement tips: Always replace with the correct rated valve for your compressor.
6. Regulator and Gauges
Control and display the output pressure, ensuring your tools receive the correct airflow.
- Common issues: Inaccurate readings or inability to adjust pressure.
- Replacement tips: Match the regulator size and input/output specifications.
7. Hoses and Fittings
Connect the compressor to tools or air lines. They must be durable and properly rated for pressure.
- Common issues: Leaks, cracks, or kinks.
- Replacement tips: Use high-quality, compatible hoses and fittings.
8. Lubrication Parts
Some compressors require oil for lubrication, including oil filters and oil reservoirs.
- Common issues: Insufficient lubrication leading to wear.
