128-9654 Nylon Composite Circle Drawbar Wear Strip for Cat Motor Graders

The 128-9654 wear strip is a non-metallic replacement component used in the circle drawbar system of selected Cat motor graders. It provides a serviceable contact layer between the drawbar, circle shoes and circle, helping prevent direct hard contact between mating components during blade rotation and positioning.

Manufactured from a black nylon-based composite material, the strip is designed to provide low-friction sliding contact while acting as a replaceable wear component. Its published overall length is approximately 178 mm, with a width of approximately 64 mm and a nominal material thickness of 7.9 mm. The molded profile incorporates two mounting features for installation in the applicable drawbar arrangement.

Composite and metallic wear strips can be used in different grader configurations. On certain H-Series machines, 128-9654 may be used as a composite service alternative to the metallic 6G-4524 wear strip. However, material type, mating components and maintenance requirements should be checked before conversion. Part numbers 6G-4524 and 380-7417 must not be assumed to have the same material or specifications as 128-9654.

For accurate B2B order confirmation, buyers should provide the machine model, serial number, existing part number, product photos and critical mounting dimensions.
