85000491 SP1 VOLVO Twin Cylinder Air Compressor

The high-strength component functions as a critical part of the pneumatic system, providing consistent air pressure for heavy-duty commercial vehicle operations. This twin cylinder design is engineered to handle demanding thermal loads through an integrated water-cooling system, ensuring stable performance during long-haul transport. The precision-engineered components maintain structural integrity under high-pressure cycles within the air brake system.

85000491 SP1 is the OE-equivalent of the VOLVO 85000491 SP1 air compressor used in VOLVO heavy commercial vehicles. This unit features a cylinder bore of Ø85.00, a 62 mm stroke, and a swept volume of 704cm³. It is specifically designed for compatibility with the (7600 850 009, 20364148 with gear) configuration, ensuring a seamless fit within the vehicle's existing air management architecture.

Workshop technicians will find the installation process straightforward due to the standardized port dimensions and through-drive design. The unit includes an M26x1.5 air outlet port and an M12x1.5 unloader port. Regular maintenance of the cooling lines and checking the water inlet/outlet ports (M16x1.5) is recommended to ensure optimal thermal management and prevent overheating during peak operation cycles.

For optimal service life, ensure that the water-cooled valve plate and ESS feature are checked during routine system maintenance. This part is engineered to meet rigorous industrial standards for durability in the most demanding heavy vehicle environments.
