7100 801 005 Compressor Crankcase for Heavy Duty

What does a compressor crankcase do?

The compressor crankcase serves as the structural foundation of the air brake compressor, housing critical rotating components and maintaining the necessary pressure seals. This high-strength component is essential for ensuring the durability of the pneumatic system and preventing air or oil leaks during high-pressure operation.

Compatible vehicles and engines

This part is fitted to a wide range of heavy commercial vehicles, including Yutong, PACCAR, KamAZ, Dongfeng, and DAF models. It is also compatible with Cummins engines such as the ISLe, ISBe, LF55, and LF45. Furthermore, it can be found in Iveco, BMC, and Volkswagen Truck applications.

Installation and maintenance

To ensure proper fitment and optimal compression performance, technicians should verify compatibility with specific engine types like the PACCAR PX-7 or Cummins ISBe. Regular inspection of the crankcase housing and sealing surfaces is recommended during scheduled maintenance to prevent system pressure drops.

Troubleshooting and selection

When replacing the crankcase or overhaul components, it is vital to check the integrity of the connecting rods and bearings to maintain long-term pneumatic efficiency.
