85000329 VOLVO FM 400 Twin Cylinder, Air Compressor

This high-strength component serves as a critical part of the pneumatic braking and air supply system, ensuring consistent air pressure for heavy commercial vehicle operations. Designed with a twin-cylinder configuration, it provides the necessary volumetric flow and pressure required for heavy-duty duty cycles. The unit features a water-cooled design to manage thermal loads effectively during extended operation.

85000329 is the OE-equivalent of the VOLVO 85000329 twin cylinder air compressor used in the VOLVO FM 400. This part is engineered to meet strict technical specifications, featuring a Ø85.00 mm cylinder bore and a 62 mm stroke to maintain optimal swept volume performance. It is specifically designed for seamless integration into the air brake systems of the specified heavy commercial vehicle models.

For workshop technicians and fleet managers, this unit offers precision assembly with an M26x1,5 air outlet port and an M12x1 air unloader port. The inclusion of the ESS feature and a water-cooled valve plate ensures stability under high-load conditions. Regular maintenance of the cooling system and checking the water inlet and outlet ports (M16x1,5) is recommended to ensure long-term reliability during service intervals.

Technical specifications include a Ø35 air inlet port and a total weight of 20.8 KG. This robust construction guarantees that the air compressor maintains structural integrity even under extreme thermal and mechanical stress within the engine compartment.
