Ступица шкива коленчатого вала Caterpillar 351-9778

The Crankshaft Pulley Hub is mounted at the front end of the crankshaft to support belt-driven accessories. It allows secure transmission of torque from the crankshaft to connected rotating elements. The hub is aligned to ensure balanced rotational movement and minimize wear on adjoining systems. It contributes to maintaining engine timing and smooth accessory operation by ensuring consistent pulley engagement.Attributes:• Maintains firm attachment between crankshaft and peripheral rotating components.• Enables efficient operation of the alternator, water pump, and other systems.• Protects surrounding systems by maintaining consistent pulley-to-crankshaft alignment.Applications: The Crankshaft Pulley Hub is applied in power units to drive multiple belt-operated systems. It enables synchronous rotation of connected accessories by transmitting crankshaft power efficiently, ensuring optimal system performance.
