85000336 VOLVO FM 12/420 Twin Cylinder, Air Compressor

The technical function of this twin cylinder air compressor is to provide consistent air pressure for the pneumatic systems of heavy commercial vehicles. Designed as a critical component for the engine system, it utilizes a water-cooled mechanism to maintain optimal operating temperatures during high-load cycles. The robust construction ensures that the air supply remains stable even under demanding industrial driving conditions.

85000336 is the OE-equivalent of the VOLVO 85000336 Twin Cylinder, Air Compressor used in the VOLVO FM 12/420. This component is specifically engineered to match the precise requirements of the FM 12/420 series, ensuring seamless integration with existing engine architectures. By maintaining strict adherence to original specifications, it offers a reliable alternative for fleet maintenance and workshop repairs.

For the workshop technician, this unit features an M26x1,5 air outlet port and an M12x1 air unloader port. The installation requires attention to the water inlet and outlet ports (M16x1,5) to ensure effective cooling through the water-cooled valve plate. Regular inspections of the through-drive and port seals are recommended to maintain peak performance within the vehicle's pneumatic circuit.

Maintaining precise air pressure is essential for vehicle safety and braking efficiency. This twin cylinder model is designed with a swept volume of 704cm³ and a diameter of Ø85.00 to meet the heavy-duty demands of long-haul transport. Using high-strength components ensures that the compressor can withstand the thermal and mechanical stresses typical of heavy-duty commercial engine environments.
