85000336 Compatible Twin Cylinder Compressor for Volvo FM12

What does a twin cylinder compressor do?

This twin cylinder compressor plays a critical role in the pneumatic braking system of heavy commercial vehicles by providing a consistent air supply. Designed with high-strength components, it ensures efficient pressure generation even under demanding service conditions. The unit features a water-cooled valve plate to maintain optimal operating temperatures during continuous use.

Vehicle and engine compatibility

This specific model is designed to fit Volvo FM12 trucks, including variants such as the FM 12/340, FM 12/420, and FM 12H/460 equipped with D12D engines. It serves as a reliable replacement for OE-standard components in these specific vehicle configurations.

Installation and maintenance

Installation requires attention to the water cooling ports (M16x1,5) and the air outlet (M26x1,5) to ensure a leak-free seal. Technicians should verify the through-drive alignment and the condition of the air unloader port (M12x1) during routine maintenance to prevent system pressure fluctuations.

System maintenance tips

Regular inspection of the water inlet and outlet connections is recommended to avoid cooling inefficiencies. Maintaining clean air filtration in the system helps preserve the integrity of the internal valves and ensures long-term performance.
