    About this product

    Cat drive train components must endure incredible torque, high impact loads, and frequent direction and gear changes. Cat designs and manufactures its transmissions and final drive components with these demands in mind. The result is a drive train that lasts longer and works harder over the life of the machine.

    • Hardened steel bevel pinion
    • 13 teeth
    • ID: 51 mm (2 in)

    Bevel pinions are used in differential systems to transmit power from the engine to the final drive in Cat drive train systems. Consult your owner’s manual or contact your local Cat Dealer for more information.
