370-1747: Transmission Ring Gear

Description: 370-1747 is a ring gear used in planetary gear sets of transmissions. 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.
