21353442 Mack MRU MP7 Compressor Equivalent

What does a single cylinder compressor do?

This single cylinder compressor serves as a vital component within the pneumatic braking system, ensuring consistent air pressure generation for heavy commercial vehicles. Engineered with high-strength components, it is specifically designed to withstand the rigorous thermal and mechanical stresses found in heavy-duty operation.

Vehicle and engine compatibility

This unit is compatible with Mack MRU trucks equipped with MP7 engines. The design integrates seamlessly into the engine's cooling circuit to maintain optimal operating temperatures during sustained high-load transport tasks.

Technical specifications and installation

Technicians should note the specific technical parameters: the unit features an Ø85.00 mm cylinder bore, a 56 mm stroke, and a 318cm³ swept volume. For correct installation, ensure the M26x1,5 air outlet port and M16x1,5 water ports are properly secured to prevent leaks. The through drive configuration supports stable mechanical coupling to the engine.

Maintenance and troubleshooting

Regular inspection of the water inlet and outlet ports is recommended to prevent scale buildup. Maintaining the cooling circuit integrity helps preserve the longevity of the water-cooled valve plate and ensures consistent performance across all operating conditions.
