Head Overhaul Kit with Filter Compatible with Ingersoll Rand SS5 Air Compressor – Reference 20100277

Product Overview

The Compatible Head Overhaul Kit with Filter (Reference 20100277) is a quality aftermarket repair kit designed for compatible use with select Ingersoll Rand SS5 single-stage reciprocating air compressors.

The cylinder head contains the valve system responsible for controlling airflow into and out of the compressor cylinder during every compression cycle. Over time, valve components, gaskets, and the air intake filter are subjected to heat, pressure, airborne contaminants, and continuous operation. As these components wear, compressor performance may decline, resulting in reduced air output, longer recovery times, excessive operating temperatures, and difficulty reaching maximum pressure.

This 20100277 compatible head overhaul kit combines the primary components commonly replaced during cylinder head service, including valve sealing components and an air intake filter, making it an ideal solution for preventive maintenance, head repairs, and restoring compressor performance.

Always verify your compressor model and existing part number before ordering. Compressor configurations may vary depending on production year and previous repairs.

Technical Specifications

Component Function

The cylinder head valve system regulates intake and discharge airflow during every compression cycle. Proper valve operation allows the compressor to efficiently compress air while maintaining rated pressure.

The head gasket and valve plate gasket create pressure-tight seals between the cylinder, valve plate, and cylinder head, while the intake filter helps prevent dirt and airborne contaminants from entering the compressor pump.

Replacing worn valve components, gaskets, and the air filter during the same service interval helps restore efficient compressor operation and supports longer service life.

Common Symptoms of Head Component Wear

A worn cylinder head or valve assembly may result in:

• Reduced air delivery
• Longer compressor pump-up time
• Inability to reach maximum operating pressure
• Air leaking back through the intake filter
• Excessive operating temperature
• Increased compressor noise
• Reduced compressor efficiency
• Higher energy consumption

Common Causes of Failure

Head overhaul components commonly wear due to:

• Normal operating wear
• Continuous heavy-duty operation
• Dirty intake air
• Overheating
• Carbon buildup
• Damaged valve reeds
• Deteriorated head gaskets
• Delayed filter replacement
• Improper previous installation

Routine inspection and scheduled maintenance help prevent unexpected compressor downtime.

When Should This Kit Be Replaced?

Replacement is recommended when:

• The compressor cannot maintain rated pressure.
• Valve components show signs of wear or damage.
• Cylinder head gaskets leak.
• Air leaks back through the intake filter.
• The compressor experiences excessive operating temperatures.
• The cylinder head is removed for servicing.
• Scheduled preventive maintenance is being performed.

Replacing the complete head service components together helps reduce repeat repairs and improves compressor reliability.

Installation Notes

Installation Difficulty: Moderate

For best results:

• Disconnect electrical power before servicing.
• Completely relieve air pressure from the receiver tank.
• Remove the existing intake filter assembly.
• Thoroughly clean all gasket sealing surfaces.
• Replace all removed gaskets with new components.
• Inspect the cylinder head for cracks or excessive carbon deposits.
• Tighten fasteners evenly using the recommended tightening sequence.

Note: Installation procedures and torque specifications vary by compressor configuration. Refer to the appropriate service documentation for your compressor.

Maintenance Tip

Whenever installing a 20100277 Head Overhaul Kit, inspect the following components:

• Cylinder head
• Valve plate assembly
• Valve reeds
• Cylinder bore
• Piston
• Air intake filter housing
• Cooling fins
• Pressure relief valve

Replacing worn components during the same maintenance interval can improve compressor performance and reduce future downtime.
