85000118 VOLVO FM 12/420 Single Cylinder Air Compressor

This single cylinder air compressor is a critical component for maintaining consistent pneumatic pressure within the vehicle's air brake system. Engineered with a Ø85.00 mm bore and a 62 mm stroke, the unit provides a reliable swept volume of 352cm³ to ensure optimal performance. Designed for heavy-duty service, this water-cooled assembly maintains thermal stability even under high-load operating conditions.

85000118 is the OE-equivalent of the VOLVO 85000118 single cylinder air compressor used in the VOLVO FM 12/420 heavy commercial vehicle. This precision-engineered part ensures seamless integration with the existing engine architecture to maintain peak system efficiency. The assembly is specifically designed to meet the rigorous demands of professional transport-grade engine systems.

For workshop technicians, this unit offers straightforward installation with through-drive capability and integrated ESS features. The technical specifications include an M26x1,5 air outlet port and an M12x1,5 air unloader port, alongside M16x1,5 water inlet and outlet ports for efficient thermal management. Regular inspection of the water-cooled valve plate and port connections is recommended during standard service intervals to ensure long-term reliability.

Maintaining the air compressor is essential for the overall health of the pneumatic braking system. This component is built to withstand the high-pressure environments typical of heavy commercial vehicle applications, providing consistent output for both braking and suspension systems.
