Description

What does a compressor cylinder head do?

A compressor cylinder head is the cast service component that sits on top of an air brake compressor's cylinder block and seals the compression chamber from above.

Compatibility and application

This component is essential for workshop technicians performing rebuilds on air brake compressors, allowing for a targeted repair rather than a full unit replacement. It functions by housing the inlet and discharge valve seats, internal air passages, and necessary cooling cavities to manage thermal loads during operation.

Installation and maintenance

This part is specifically compatible with MAN vehicles. When selecting replacement components, ensure the architecture matches the existing unit, as variations in valve plate configurations or cooling methods are common across different engine options.

Selection guidance

Proper installation of this cylinder head ensures the integrity of the compression chamber and maintains consistent air output for the braking system. Consult your authorized distributor for fitment verification.

OE cross-reference

12 11 50 (Compressor Cylinder Head) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 51541017189S1.

FAQ

What is the function of a compressor cylinder head?
The cylinder head seals the compression chamber from above and houses the valve seats and air passages required to regulate air output and temperature.
Can this part be used to rebuild an existing compressor?
Yes, this component allows workshop technicians to rebuild an air brake compressor in place instead of replacing the entire unit.
Which vehicles is this component compatible with?
This specific cylinder head is designed to be compatible with MAN vehicles and their associated pneumatic systems.
Why are there different types of cylinder heads?
Heads vary by architecture, such as single-cylinder, twin-cylinder, air-cooled, or water-cooled designs, depending on the specific engine and air demand requirements.
What are the OE reference numbers of this part?
12 11 50 directly replaces MAN OE number 51541017189S1.
