51541007178 MAN ÜL Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, providing the necessary air pressure required for reliable operation. Built with high-strength components, it is designed to withstand the demanding thermal and mechanical stresses found in heavy commercial vehicle environments.

Vehicle and engine compatibility

This unit is specifically compatible with MAN ÜL 363 and 313 models. It functions efficiently within the air brake system to ensure consistent pressure delivery for the vehicle's pneumatic components.

Installation and maintenance

Technicians should ensure that the water inlet and outlet ports (M22x1,5) are correctly connected to the cooling circuit to maintain optimal operating temperatures. Regular inspection of the M26x1,5 air ports and the through drive interface is recommended during routine maintenance to prevent system leaks or mechanical failure.

System maintenance guidance

For optimal performance, verify that all mounting points are secure and that the water-cooled valve plate remains free of debris to ensure maximum volumetric efficiency.
