Failure Symptoms

The first sign of a failing cylinder head is often a noticeable air leak from the compressor unit, or a significant increase in the time it takes to build air pressure. If ignored, the compressor may fail to build adequate pressure, leading to issues with air brakes or suspension. This can compromise vehicle safety and operational capability.

Installation Tip

Ensure the mounting surfaces on the compressor block are perfectly clean and flat before installing the new head. Always use a new head gasket and torque the bolts in the specified sequence and to the correct values.

Service Note

When replacing the compressor cylinder head, it is essential to also replace the compressor gasket set and inspect the compressor valves for wear.
