3097150 Crankshaft Flange for Volvo D13

What does a crankshaft flange do?

The compressor crankshaft flange serves as the critical 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, performing essential centering, sealing, and load transfer duties between the compressor housing and the crankshaft. This component ensures that the drive mechanism—whether gear, belt-pulley, or coupling—reaches the crankshaft in a perfectly centered position.

Compatibility with Volvo loaders

This specific part is designed for use in Volvo L150H / L250H loaders featuring D13 engines. It is a vital component for maintaining air pressure stability in heavy construction machinery. By ensuring precise alignment, it prevents premature wear on internal compressor seals and bearings.

Installation and maintenance

When performing maintenance or repairs on the air brake system, technicians should inspect the flange for signs of uneven wear or seal seat damage. Proper installation is crucial to ensure the load transfer duty is met without causing vibration in the drive assembly. Always consult your authorized distributor to verify correct fitment.

System reliability

Ensuring the integrity of this component helps prevent air leaks and pressure drops within the pneumatic system of heavy equipment.
