1300 185 001 Twin Cylinder, Air Compressor — VOLVO

The high-strength Twin Cylinder, Air Compressor serves as a vital component in the pneumatic system of heavy commercial vehicles, providing reliable air pressure for braking and auxiliary functions. This water-cooled unit is engineered to maintain stable operation under intense thermal loads, featuring a robust Ø85.00 cylinder bore and a 62 mm stroke to ensure consistent volumetric efficiency within the engine compartment.

This part is the OE-equivalent of the VOLVO 20574763, 20775224, 20866605, 70330056, and 85000491 air compressors used in VOLVO and RENAULT TRUCKS. It also provides full compatibility with WABCO systems including references 412 704 002 0, 412 704 002 7, 412 704 007 0, 412 704 007 7, 412 704 013 0, 412 7{...} and other specific WABCO hardware configurations.

Workshop technicians should note that this unit is designed for water-cooled applications, utilizing M16x1,5 inlet/outlet ports to manage thermal regulation effectively. The assembly features a through-drive design and an ESS feature to ensure seamless integration with the existing engine architecture. Regular inspections of the water inlet/outlet ports and the M26x1,5 air outlet port are recommended during routine maintenance to prevent leakage or pressure drops.

Maintaining the correct air unloader port clearance and ensuring the water-cooled valve plate remains unobstructed is essential for long-term operational stability in heavy-duty truck applications.
