1518349 Volvo F7 TD71 Compressor Crankshaft Flange

What does a crankshaft flange do?

The crankshaft flange serves as a vital 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 essential duties of centering, sealing, and load transfer between the housing and the crankshaft. This ensures that the drive mechanism reaches the crankshaft in a perfectly centered position.

Vehicle and engine compatibility

This specific component is compatible with Volvo F7 trucks equipped with TD71 engines. It is engineered to withstand the rigorous operating conditions of heavy commercial vehicle pneumatic systems, providing stability to the compressor assembly during high-pressure cycles.

Installation and maintenance guidance

When performing maintenance or replacement, technicians should verify the pilot diameter, bolt hole circle, and seal seat size against the existing component. Precise matching is required to prevent premature leakage or excessive vibration in the compressor assembly. Always check the casting number or housing label on the original part to ensure exact fitment.

Ensuring correct fitment

Proper installation of this flange helps maintain optimal air pressure delivery by ensuring a tight seal and stable rotation of the compressor crankshaft.
