81125437 VOLVO B10M Twin Cylinder, Air Compressor

The 81125437 twin cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles. Designed to provide consistent air pressure, this unit utilizes a robust two-cylinder architecture to ensure high-performance output and long-term reliability under demanding service conditions. Its specialized design is engineered to maintain operational stability within the vehicle's air brake compressor system.

This specific model is the OE-equivalent of the VOLVO 81125437 air compressor used in the VOLVO B10M. The assembly features a cylinder bore of Ø88.00 and a stroke of 50 mm, resulting in a swept volume of 608cm³. The component is specifically designed for water-cooled (W) systems, utilizing M16x1,5 ports for both water inlet and outlet to manage thermal loads effectively during operation.

For workshop technicians performing maintenance or engine overhauls, this part offers precise fitment with an air unloader port of M22x1,5 and an air outlet port of M26x1,5. It is essential to verify the compatibility of the water cooling lines and the through-drive configuration during installation to ensure seamless integration with the existing engine block. Regular inspections of the air inlet (Ø29) and cooling ports are recommended to maintain optimal pressure levels and prevent system overheating.
