7200 851 019 Compressor Crankshaft for Cummins Engines

What does a compressor crankshaft do?

The compressor crankshaft serves as the central component in the air brake compressor, responsible for converting the engine's rotary motion into the reciprocating motion required for the compression stroke. This high-strength component is essential for maintaining optimal pneumatic pressure within the braking system of heavy commercial vehicles.

Vehicle and engine compatibility

This part is designed to be compatible with Cummins ISM and N14 engines. It is fitted to a wide range of heavy-duty vehicles including Freightliner, Peterbilt, Kenworth, Volvo, and International models, as well as various bus chassis like Gillig and New Flyer. It also serves Ford Trucks and Sterling vehicles equipped with appropriate engine series.

Maintenance and installation guidance

For workshop technicians, maintaining the integrity of the crankshaft assembly is vital for preventing noise, vibration, or air leakage. When inspecting the compressor, ensure that the crankshaft rotation is smooth and free of excessive play to maintain system pressure. This component is a key part of the overhaul process when renewing internal moving parts within the pneumatic assembly.

System reliability

Proper selection of crankshaft components ensures long-term reliability in demanding transport environments. Always verify engine compatibility before installation to ensure seamless integration with existing WABCO systems.
