1698156 Compatible Cylinder Head for Volvo B12 TD120

What does a compressor cylinder head do?

This compressor cylinder head serves as the essential cast component that seals the top of the air brake compressor's cylinder block. It provides the necessary seating for inlet and discharge valves while ensuring that compressed air remains contained within the system without leakage. By routing air through the discharge port, it plays a vital role in the pneumatic system's overall efficiency.

Vehicle and engine compatibility

This specific component is compatible with Volvo B12 trucks utilizing the TD120 engine. It is engineered to meet the rigorous demands of heavy commercial vehicle service, providing a reliable solution for rebuilding compressors in place rather than replacing the entire unit. It ensures precise fitment and optimal pressure maintenance for the vehicle's air brake system.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the valve seats and ports for any signs of wear or carbon buildup. Ensuring a clean mating surface during installation is critical to maintaining high-strength compression and preventing air leaks. This part is designed to withstand high-temperature cycles common in heavy-duty engine environments.

Troubleshooting and selection

Regular inspection of the cylinder head can help prevent unexpected downtime in fleet operations. Checking for cracks or erosion around the discharge port can ensure the longevity of the compressor assembly.
