The oil cup top part, designated by code K 12031, is an integral component of the engine’s lubrication support system. Positioned to collect or distribute lubricating oil in specific zones of the engine assembly, it helps regulate oil flow and prevent spillage or contamination. Built from oil-resistant and thermally stable materials, this upper segment of the oil cup plays a key role in ensuring consistent lubrication and supporting maintenance-free operation over extended service periods. Its design complements the lower part of the oil cup for seamless integration.
