7100 851 018 Compressor Crankcase for Cummins Engines

What is a compressor crankcase?

The compressor crankcase serves as the primary structural housing for the internal moving components of the air brake compressor. It provides the necessary support for the crankshaft and ensures the precise alignment of the piston assembly, which is critical for maintaining consistent air pressure within the pneumatic braking system.

Vehicle and engine compatibility

This component is compatible with Cummins N14 and ISM engines found in a wide range of heavy commercial vehicles, including Peterbilt, Kenworth, Volvo, and Freightliner models. It is also frequently utilized in Sterling, International, and Ford Trucks to ensure reliable braking performance across various heavy-duty applications.

Installation and maintenance

When performing maintenance or an overhaul, technicians should verify that all seals and gaskets provide an air-tight integration within the crankcase housing. Proper installation ensures that the rotation from the engine is efficiently converted into compression without leakage or excessive vibration.

System performance and selection

Ensuring correct fitment is vital for maintaining the integrity of the pneumatic system. For optimal performance in heavy commercial vehicles, always check compatibility with WABCO systems and ensure all mounting tolerances are met during assembly.
