The bush K 41113 is a precision bearing and guiding component designed for the toothed wheels K 41110 and K 41120 within the camshaft drive of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Its primary function is to provide a stable bearing surface that supports accurate rotation of the toothed wheels while reducing friction and protecting the associated shafts and gear components from excessive wear. During engine operation, the bush is subjected to continuous rotational movement, cyclic mechanical loads, vibration, and the demanding lubrication conditions characteristic of a heavy-duty camshaft drive. Accurate dimensions, correct clearances, suitable bearing material, and effective lubrication are therefore essential for maintaining proper gear alignment and smooth transmission of motion. Wear or excessive clearance in the bush can adversely affect gear engagement and increase vibration, noise, and loading on neighboring components. By maintaining precise support and alignment of the K 41110 and K 41120 toothed wheels, the K 41113 bush contributes to reliable camshaft drive operation, reduced component wear, correct engine timing, and long-term reliability of the ZV40/48 engine.
