7100 702 003 Compressor Crankcase for Heavy Duty

What does a compressor crankcase do?

The compressor crankcase serves as the foundational housing for the internal moving components of the air brake compressor. It provides the structural integrity required to manage the reciprocating motion of the piston and crankshaft, ensuring stable air compression for the vehicle's pneumatic braking system. This component is vital for maintaining consistent air pressure delivery under heavy-duty service conditions.

Vehicle and engine compatibility

This crankcase is compatible with various heavy commercial vehicles including Freightliner models like the Cascadia and Columbia, Kenworth series such as the W900 and T800, and Peterbilt trucks like the 379 or 389. It is designed to integrate seamlessly with engines from Caterpillar (C15, C16, 3176) and Detroit Diesel (Series 60), providing a reliable solution for fleet maintenance and engine overhaul requirements.

Maintenance and installation guidance

When performing maintenance or responding to symptoms of air leakage or excessive vibration, verifying the exact fitment of the crankcase is essential. Proper installation ensures that the connecting rod and bearings maintain correct axial and radial clearances. For optimal performance, technicians should ensure all mating surfaces are clean and seals are seated according to manufacturer specifications to prevent oil contamination within the pneumatic circuit.

Troubleshooting and selection

This part is an essential component for renewing air brake compressor assemblies in various heavy-duty applications. Check the compatibility list to ensure correct fitment for your specific engine configuration.
