1100 258 001 Twin Cylinder, Air Compressor

This high-strength component is engineered to provide reliable air pressure for heavy commercial vehicle braking systems. The twin cylinder configuration ensures consistent output and durability under demanding operating conditions. It is specifically designed to integrate seamlessly into the air brake system of the vehicle to maintain optimal pneumatic pressure.

The 1100 258 001 is the OE equivalent of the MERCEDES BENZ 4601300015 and WABCO 91251070 used in various heavy-duty applications. This unit is compatible with MERCEDES BENZ and WABCO systems, as well as specialized engine configurations such as the MBE 4000 found in FREIGHTLINER, STERLING, WESTERN STAR, and DETROIT DIESEL vehicles. It features a Ø85.00 mm bore and a 56 mm stroke to meet strict technical requirements.

For technical maintenance, this water-cooled unit utilizes an M26x1,5 air inlet/outlet port configuration and an M12x1,5 air unloader port. The integration of the ESS feature and water-cooled valve plate ensures stability during high-load cycles. Technicians should verify the M16x1,5 water inlet and outlet ports during installation to ensure proper thermal regulation of the compressor unit.

The assembly is optimized for durability in professional workshop environments. When replacing the air compressor, ensuring compatibility with the existing engine (such as MBE 4000) and the braking system architecture is essential for long-term reliability.
