25 22 12 Crankshaft Flange for Air Brake Compressors

What does a compressor crankshaft flange do?

This compressor crankshaft flange plays a critical role in the pneumatic compression process by ensuring stable rotational connection within the air brake compressor assembly. Manufactured with heavy-duty grade materials, it is designed to withstand the high-pressure and high-temperature cycles typical of heavy commercial vehicle braking systems.

Compatible vehicles and engines

This component is compatible with various heavy commercial vehicle applications, including Dongfeng models such as Tianjin, Kinland, Duolika, and Captain, as well as KamAZ series 65115, 4308, 5308, and 6520. It is also fitted to Ford Trucks Cargo, Iveco Bus Metro, and Yutong ZK6125/ZK6118 models using Cummins ISBe or ISLe engines. Other compatible vehicles include Liaz 5292, Paz 3204/3237, Zhongtong LCK6118, Nefaz 5299, Volkswagen Constellation, and Volkswagen Truck models.

Installation and maintenance

For optimal performance, technicians should inspect the flange mounting surface for any signs of uneven wear or thermal stress during routine air system maintenance. Ensuring a clean interface during installation is vital to maintain the integrity of the compressor's internal seals and prevent air leakage or vibration issues in the pneumatic circuit.

Troubleshooting and inspection

Regular inspection of the crankshaft assembly helps prevent catastrophic failure of the compressor unit. When replacing this part, verify that all connecting components are aligned to maintain proper compression efficiency throughout the engine's service life.
