CATERPILLAR-IDLER-PULLEY

Part 279-2589 is a Caterpillar idler pulley manufactured to OEM bearing and pulley-groove tolerances, ensuring the accessory belt tracks true without walking off the pulley face under vibration. Idler bearing wear is one of the more common causes of belt-related breakdowns on Cat equipment simply because it's easy to overlook during routine inspection — there's no belt tension to check, just bearing play.
