5T-2989: Left Hand Brake Camshaft

Description: Brake camshafts, such as 5T-2989, are used to transfer power to air-actuated, S-cam operated shoe type braking mechanisms. The cam rotates when the brakes are actuated, pushing the brake shoe against the brake drum to produce the friction needed to slow or stop the machine. 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.
