Worn main bearings like the 612630020018 often cause a drop in oil pressure. As the clearance between the crankshaft and the bearing increases, oil escapes too easily, reducing the overall pressure. Replacing the bearings during an overhaul is the standard solution.
While possible, it is highly discouraged. For a successful engine rebuild, all main bearings should be replaced as a matched set to ensure uniform load distribution and consistent oil pressure across the crankshaft.
Listen for "engine knocking" sounds, especially when the engine is under load. Metal shavings in the oil filter are also a definitive sign that your bearings are disintegrating and require immediate replacement.
