POLY WHEEL ASSEMBLY (CAT CT109977)

CT109977: A worn poly wheel assembly can cause uneven rolling and increased vibration during movement. The CAT catalog reference CT109977 identifies this aftermarket replacement part, which is a wheel assembly made with polyurethane. Its primary function is to support load and enable smooth rotation under weight. A common failure consequence is that a degraded poly wheel may develop flat spots, leading to jerky motion and potential load instability. Keeping the wheel assembly in sound condition helps maintain consistent travel and reduces stress on other components. This item ships at approximately 2.636 pounds.
