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.
The water separator with code K 16022 plays a crucial role in the crankcase ventilation system of the ZV40/48 engine. It removes moisture and condensation from the crankcase air before it is expelled or recirculated, thus preventing water vapor from contaminating engine oil or corroding internal parts. Engineered for high efficiency and minimal pressure drop, this component ensures cleaner crankcase emissions and enhances engine longevity. Its function is particularly important in marine environments or high-humidity conditions where condensation buildup is a persistent challenge.
The plate coded K 16216 serves as an essential part of the control room casing in the ZV40/48 diesel engine. Designed for structural integrity and environmental shielding, this plate protects the sensitive control mechanisms housed within the casing from dust, oil mist, moisture, and mechanical impact. It is fabricated from corrosion-resistant materials to ensure long-term durability and consistent performance in demanding industrial or marine settings. The precision fit of this plate helps maintain the alignment of the casing and supports the engine’s overall operational reliability.
The hexagon screw, code EN61V1230, is a standard threaded fastener used widely in the MAN L21/31 engine assembly. Known for its hexagonal head, it allows for strong torque transfer and secure fastening of engine components. Engineered from high-grade steel, it withstands operational stress, vibration, and high temperatures, playing a vital role in maintaining structural cohesion across various mechanical connections.
The washer, code 06.16169-0004-1.A, serves as a flat, load-distributing element placed between a fastener and the engine surface. It ensures even pressure application and protects mating surfaces from deformation or damage during tightening. In the MAN L21/31 engine, this component contributes to joint stability, corrosion resistance, and proper alignment of components during assembly or servicing operations.
The locking spring washer with code 06.16169-0004.2 is a crucial safety component used in bolted connections within the MAN L21/31 engine. Designed to prevent nuts and bolts from loosening under vibration and thermal expansion, this washer exerts a continuous tension against the fastener head. Its split-ring, spring-like design provides reliable anti-rotation performance, making it essential in securing structural and dynamic parts in both marine propulsion and stationary engine applications.
