383-8012: Gear

Description:
Cat® Gears are machined from carefully selected materials to exacting specifications that match the loads encountered in Cat machines. They are manufactured using special, and in some cases proprietary, heat treat processes — including case carburizing, nitriding, and induction hardening. Cat® Gears have the industry's highest power density, or the amount of power a gear can transmit relative to its size and are designed with reusability in mind. Consequently, they are more durable and keep your overall machine operating costs down. Cat® Replacement gear for the Idler Shaft group in the final drive. This gear has two gear profiles, namely external helical gear and external involute spline.
Cat® Parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact, and reuse.
