Heavy-Duty Clutch Friction Disc – Replaces CAT 6Y2027

The clutch friction disc 6Y2027 is designed for reliable power transfer in Caterpillar transmission systems used across graders, articulated trucks, Challenger tractors, and petroleum drive applications. Engineered for durability and thermal stability, this disc delivers dependable clutch performance in demanding field conditions.

Featuring a precision-machined steel hub, this friction disc resists spline deformation and maintains proper alignment under load. The multi-groove friction surface promotes oil circulation and heat control, reducing clutch fade during extended operation. With a 101-spline internal configuration, it installs seamlessly into compatible CAT assemblies without modification.
