Description:
Part # 611-8517 is used in the braking system to reduce machine speeds.

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 with steering and braking systems, providing critical friction to slow, stop or hold a machine stationary.

Attributes:
• Diamond pattern grooves for optimized for cooling
• Cat proprietary friction material ensures both performance and life.
• Internal spline provides exact OEM fit
• Hardened steel core reduces spline wear
• Inside Diameter: 128.5mm (5.05 in)
• Outside Diameter: 180mm (7.08 in)
• Thickness: 2.9mm (0.11 in)

Application:
Cat friction discs are used as part of the transmission system to provide maximum performance and life to the drivetrain. Consult your owner’s manual or contact your local Cat Dealer for more information.
