The gear wheel bearing code K 71030 is a precision-machined component that drives the oil pump in the Sulzer ZV40/48 diesel engine. Its accurately cut teeth mesh with the mating gear to generate the flow and pressure necessary for engine lubrication. Constructed from hardened, wear-resistant steel, the wheel endures heavy load and high rotational speeds, ensuring reliable oil delivery to critical bearings and seals. Regular inspection of the gear wheel for wear and clearances helps maintain optimal lubrication performance and prevents premature engine wear.
