4936226 Compressor Cylinder Head compatible with Cummins

What does a compressor cylinder head do?

This compressor cylinder head acts as the critical cast component that seals the top of the air brake compressor's cylinder block, creating a secure compression chamber. By housing the seats for the inlet and discharge valves, it directly regulates both the air output and the thermal management of the unit during operation.

Compatible engines and applications

This specific component is engineered to be compatible with Cummins engines, including the QSC8.3, ISM, QSM11, ISB6.7, QSB6.7, N14, ISL, QSL9, and M11 series. It serves as a vital replacement part for workshop technicians looking to rebuild an existing compressor unit rather than replacing the entire assembly.

Installation and maintenance

When performing maintenance or repairs, ensure that the cylinder head is inspected for any signs of uneven wear on the valve seats or thermal stress on the cooling cavities. Proper installation is essential to maintain pressure integrity and prevent air leaks within the pneumatic system.

System reliability

Maintaining a robust compression chamber requires high-strength components that can withstand continuous heavy-duty cycles in commercial vehicle applications.
