16 17 11 PACCAR MX13 MX11 Cylinder Head

What does a compressor cylinder head do?

This 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. It is a vital component for maintaining pneumatic pressure in heavy-duty braking systems.

Compatible vehicles and engines

This part is specifically designed for PACCAR engines, including the MX13 and MX11 series. It is compatible with various heavy commercial vehicle models such as Kenworth T800, T880, T680, W990, T660, and W900S, as well as Peterbilt 386, 579, 367, 388, 589, 567, 587, 365, 384, and 389. This component is also suitable for WABCO systems.

Installation and maintenance

When performing maintenance or rebuilding an air brake compressor, technicians should inspect the cylinder head for signs of thermal stress or valve seat wear. Ensuring a proper seal during installation is critical to preventing pressure drops within the air brake system. Check the compatibility list.

System reliability

Maintaining regular inspection intervals of the compressor assembly can prevent broader system failures. This cylinder head is manufactured to meet rigorous standards to ensure long-term reliability in demanding environments.
