7100 751 019 Compressor Crankcase Equivalent — Cummins

What does a compressor crankcase do?

The compressor crankcase serves as the central housing for the rotating assembly within the air brake compressor. It provides the structural integrity required to house the crankshaft and bearings, converting the engine's rotational motion into the linear piston movement necessary for air compression. This component is vital for maintaining consistent pressure within the pneumatic brake system.

Vehicle and engine compatibility

This part is compatible with Cummins ISB engines and is fitted to various heavy commercial vehicles including Ford Trucks CF700, Freightliner FL50, Volkswagen Constellation, Ram 4500, Blue Bird Vision, Peterbilt 330, Kenworth T370, and many others. It ensures seamless integration with WABCO systems and other professional-grade pneumatic components.

Installation and maintenance

For optimal performance, technicians should verify that the crankcase surface is free of scoring and that all mounting points align perfectly with the engine block. Regular inspection of the internal bearing seats is recommended during overhaul to prevent vibration or oil leakage issues within the compressor assembly.

Reliability and selection

Selecting a high-strength component ensures long-term reliability under heavy-duty operating conditions. Consult your authorized distributor for specific fitment details.
