A4471300045 Mercedes-Benz Compatible Crankshaft Flange

What does a crankshaft flange do?

The compressor crankshaft flange serves as the essential connecting element that links the air brake compressor's crankshaft to the engine drive. By carrying the bearing and seal seat on the drive side, it performs the vital duties of centering, sealing, and load transfer between the compressor housing and the crankshaft. This component ensures that the drive mechanism, whether via gear, belt-pulley, or coupling, reaches the crankshaft in a perfectly centered position.

Installation and maintenance guidance

When performing maintenance or repairs, technicians should verify the flange thickness, seal seat size, and bolt hole circle to ensure perfect alignment. Proper installation prevents premature leakage or vibration caused by misalignment. Always consult your authorized distributor to ensure correct fitment for your specific engine configuration.
