8127749 Volvo FL12 TD122 Compressor Cylinder Head

What does a cylinder head do?

This cylinder head serves as the critical cast component that seals the top of the air brake compressor cylinder block. It provides the necessary seating for both inlet and discharge valves, ensuring that compressed air is routed efficiently through the discharge port while managing heat dissipation during operation.

Compatible vehicles and engines

This specific component is designed to fit Volvo FL12 trucks featuring the TD122 engine. It functions as a vital part of the air compression cycle, maintaining the high pressure required for heavy commercial vehicle braking systems. It is recommended to verify fitment based on the specific compressor configuration.

Installation and maintenance

When replacing this part, technicians should inspect the valve seats and the cylinder block surface to ensure a perfect seal. Proper installation ensures that the compressor maintains stable pressure without leakage, which is crucial for the safety and reliability of the vehicle's pneumatic braking system.

Troubleshooting and selection

Regular inspection of the cylinder head can prevent air leaks and ensure consistent compression performance. If air pressure build-up is slow or uneven, evaluating the condition of this head and its associated valves is a recommended maintenance step.
