Caterpillar

This is a genuine used Caterpillar 1448263 idler gear, precision-engineered for the accessory drive systems of heavy-duty Caterpillar engines, including the 3500-series (3508, 3512, 3516). This 53-tooth gear is a critical component for managing rotational direction and maintaining shaft spacing within the engine&#39;s gear train. Weighing 11.20 lb, this pre-owned part has been manufactured from high-strength alloy steel, designed to withstand the extreme torque and thermal stress typical of large-scale industrial, marine, and mining applications. As a genuine CAT component, it retains the original involute tooth profile necessary for proper meshing with auxiliary drive groups. While in used condition, this gear provides a cost-effective alternative for engine repairs and maintenance in equipment like the CAT 793 mining trucks, D11 dozers, and various marine auxiliary units. Each unit should be inspected for surface integrity and tooth wear to ensure it meets the operational requirements of your specific power plant.
