11 25 51 Compressor Cylinder Head compatible with Mercedes-Benz

What does a compressor cylinder head do?

A compressor cylinder head is the cast service part that closes off the top of an air brake compressor's cylinder block and carries the seats for the inlet and discharge valves. It holds the piston's compressed air without leaking, routes it out through the discharge port, and carries away part of the compression heat from the body. This component is vital for maintaining stable air pressure within the pneumatic system.

Compatible Mercedes-Benz and Setra vehicles

This specific cylinder head is compatible with various Mercedes-Benz models, including Tourismo (O 350), Setra Series 400, Citaro (O 530), Conecto (O 345), and Integro (O 550). It is also suitable for Axor 2, Capacity, Intouro, Touro (O 500), and O 403 series engines such as OM 457 LA and OM 457 HLA. These components are often used in conjunction with WABCO systems to ensure reliable operation.

Installation and maintenance guidance

When performing maintenance or an overhaul, technicians should inspect the cylinder head for any signs of cracking or uneven wear on the valve seats. Ensuring a clean mating surface between the head and the cylinder block is essential to prevent air leaks during high-pressure cycles. Check the compatibility list to ensure correct fitment for your specific engine configuration.

Troubleshooting and selection

Proper selection of this component helps extend the service life of the entire pneumatic brake compressor, providing a cost-effective alternative to a full unit replacement.
