This sprocket transmits drive through the drivetrain of the host tractor or vehicle. It engages a chain or belt to transfer rotational motion from one shaft to another within the mechanical drive system. The seventeen-tooth profile matches the pitch of the original chain, ensuring consistent engagement and minimal vibration. A worn sprocket causes chain skip and uneven power delivery, which accelerates wear on both the chain and the mating shaft bearings. This original-manufacturer component is machined to the same tooth profile and bore tolerance as the original assembly, so it maintains the correct chain wrap and tension without requiring shimming or adapter bushings.
