What does a crankshaft flange do?

This crankshaft flange serves as the essential connecting element that links the air brake compressor's crankshaft to the engine drive. It carries the bearing and seal seat on the drive side of the crankshaft, performing vital centering, sealing, and load transfer duties between the housing and the crankshaft.

Vehicle and engine compatibility

This component is specifically compatible with Volvo F7 trucks equipped with TD71 engines. It is engineered to withstand the high-pressure environments found in heavy commercial vehicle braking systems, maintaining structural integrity during constant rotation.

Installation and maintenance guidance

When performing maintenance, technicians should verify the pilot diameter, bolt hole circle, and seal seat size to ensure a precise fit. Incorrect dimensions can lead to premature leakage or excessive vibration, even if the part appears to be an immediate match. Always check the compressor type number or casting marks before installation.

Troubleshooting and selection

Proper installation of this flange is crucial for the longevity of the compressor assembly. Ensuring a clean mounting surface helps maintain the seal integrity required for reliable air brake performance in heavy-duty service.
