Description: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. Cat friction discs are designed to work within the transmission system to absorb the high power and energy during shifting.Attributes:• Multiple parallel groove pattern optimized for cooling.• Hardened steel core reduces spline wear.• (65) tooth internal spline provides exact OEM fit.Application:Cat friction discs are used as part of the transmission system to provide maximum performance and life to the drivetrain.
