1518349 Crankshaft Flange for Volvo F7 TD70

What does a crankshaft flange do?

The compressor crankshaft flange acts as the vital 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 the essential tasks of centering, sealing, and load transfer between the compressor housing and the crankshaft. Without a precise fit, this component can lead to immediate leakage or excessive vibration.

Compatibility with Volvo F7 engines

This specific part is engineered for use in Volvo F7 trucks equipped with TD70 engines. It maintains high-strength performance under heavy commercial vehicle operating conditions, ensuring that the drive—whether via gear, pulley, or coupling—reaches the crankshaft in a perfectly centered position.

Installation and maintenance guidance

When replacing this component, technicians should verify that the pilot diameter, bolt hole circle, and seal seat dimensions match the existing unit exactly. Using an incorrect flange can cause rapid failure or oil leakage. Proper installation ensures the integrity of the pneumatic system and prevents damage to the crankshaft bearing seat.

Troubleshooting and selection
