One New Aftermarket Replacement Metallic Transmission Disc Fits Caterpillar (Fits CAT) Crawler Dozers
This metallic friction disc is a direct replacement for the steering clutch and power shift transmission system on Fits Caterpillar (Fits CAT) track-type crawler dozers. Metallic discs are used in the steering clutch pack, providing the friction surface needed for reliable clutch engagement and precise directional control. Used alongside steel separator discs in the clutch stack, this disc must be in good condition for proper steering response and to prevent premature clutch wear.
