Genuine Cat drivetrain parts, along with excellent maintenance and repair options, result in increased productivity and lower owning and operating costs. Gears, bearings, friction material and seals account for up to 40% of the cost of your equipment's drivetrain. So, it makes sense to use Cat OEM drivetrain components in all your Cat equipment. Every component is designed to work as a system for increased cost efficiency and built to deliver top performance and durability. Ultimately, repairing or replacing your Cat drivetrain with your dealer results in more drivetrain uptime, greater machine availability, and lower ownership costs throughout the life of your equipment. Cat designs and manufactures its transmissions and final drive components, keeping in mind the rigorous demands they face, including enduring incredible torque, high impact loads, and frequent direction and gear changes. To ensure their performance in real-world applications, we subject these components to rigorous testing processes. The outcome is a robust and long-lasting drivetrain that consistently delivers exceptional performance throughout the lifespan of your machine.
