4936049 ISDe Single Cylinder Air Compressor Replacement

What does a single cylinder compressor do?

This single cylinder air brake compressor is a critical component designed to provide the necessary compressed air for braking systems in heavy commercial vehicles. By utilizing a piston-type mechanism, it takes drive from the engine to compress intake air, which is then sent to the air processing unit and storage tanks. This component ensures the pneumatic pressure required for safe and consistent braking performance.

Engine and system compatibility

This specific unit is engineered to be compatible with Cummins ISDe engines. It features a through-drive configuration and is designed for heavy-duty operation within the engine's cooling circuit. The water-cooled design helps maintain optimal operating temperatures during sustained use in demanding environments.

Installation and technical specifications

Technicians should note the specific port dimensions for installation, including an M26x1.5 air inlet port and M22x1.5 air outlet port. The water circuit utilizes M16x1.5 ports for both inlet and outlet to ensure efficient thermal management. Regular inspection of the valve plate and port connections is recommended to maintain system integrity.

Maintenance and performance

When replacing this compressor, ensure the water-cooled valve plate and all connections are correctly seated to prevent pressure drops in the pneumatic circuit.

OE cross-reference

2500 190 001 (Single Cylinder Compressor) is the equivalent of the Cummins OE number. This part directly replaces Cummins OE number 4936049.
