4089222 Cummins Compatible Compressor Crankshaft Flange

This compressor crankshaft flange plays a critical role in the internal mechanics of the air brake compressor. As a vital component of the crankshaft assembly, it facilitates the precise transfer of rotational energy required for the compression stroke. Utilizing high-strength components ensures that the flange can withstand the continuous mechanical stress and vibration inherent in heavy commercial vehicle operations.

This specific flange is designed for compatibility with several Cummins engine series, including the ISC8.3, ISX15, ISX, QSB6.7, QSL9, and X12 engines. It also fits various other configurations such as the ISB6.7, ISB, QSC8.3, 6BT5.9, and QSB series. Ensuring correct engine fitment is essential for maintaining the structural integrity of the air brake system.

For workshop technicians performing compressor overhauls, verifying the flange dimensions and mounting specifications is vital. When replacing a crankshaft assembly or repair kit, inspecting the flange for wear on the seal seat or bolt holes can prevent future air leakage or excessive vibration. Proper installation ensures long-term reliability within the pneumatic system.

Consult your authorized distributor to check the compatibility list.
