85000336 VOLVO FH 12/420 Twin Cylinder, Air Compressor

This twin cylinder air compressor is an essential component for maintaining stable pneumatic pressure within the vehicle's braking system. Engineered for high-strength performance, it features a water-cooled design to manage thermal loads effectively during heavy-duty operation. The unit is built with a robust architecture to ensure consistent air delivery and long-term reliability in demanding environments.

85000336 is the OE-equivalent of the VOLVO 85000336 twin cylinder, air compressor used in the VOLVO FH 12/420. This component is specifically designed to meet the rigorous standards of heavy commercial vehicle systems, ensuring seamless integration with existing pneumatic hardware. The precise dimensions, including the Ø85.00 bore and M26x1,5 outlet port, guarantee exact fitment for the intended vehicle models.

Workshop technicians should note that this part is water-cooled and features an ESS (Electronic Speed Control) capability. When performing installation or maintenance, ensure the water inlet and outlet ports (M16x1,5) are correctly connected to the cooling circuit to prevent overheating. Regular checks of the through-drive mechanism and unloader port integrity are recommended to maintain optimal system pressure and prevent service interruptions.

For optimal performance, always verify that the air inlet (Ø35) and outlet (M26x1,5) connections are free from debris during assembly. This component is engineered to handle high-pressure cycles within the air brake system of heavy trucks.
