The locking spring washer, code 06.16169-0006.1, is designed to exert consistent tension on fasteners, helping to maintain clamping force in the MAN L21/31 engine even under thermal cycling and vibration. Its spring-like profile compensates for any loosening tendencies in bolted connections, ensuring mechanical reliability over time. Commonly used in high-stress areas, this washer is vital for the safe and uninterrupted function of engine components.
The cover, code 11.01213-0061.A, serves as a protective enclosure in the MAN L21/31 engine, designed to seal off internal engine compartments from external contaminants such as dust, moisture, or debris. Engineered with precision fit and durable materials, this component not only helps retain oil and fluids but also contributes to thermal insulation and noise reduction. Its presence is crucial for preserving internal cleanliness and ensuring reliable engine performance under harsh operating conditions.
The lock washer with code 06.16169-0003.0 is a compact but essential component in the MAN L21/31 engine, designed to prevent loosening of fasteners under dynamic loads. Its toothed or serrated structure bites into the mating surfaces, offering mechanical resistance against vibration-induced rotation. This washer ensures that bolts and nuts remain securely fastened, thereby safeguarding the stability of critical engine joints and assemblies during prolonged operation.
Сепаратор воды с кодом K 16022 играет ключевую роль в системе вентиляции картера двигателя ZV40/48. Он удаляет влагу и конденсат из воздуха в картере до его выпуска или рециркуляции, предотвращая загрязнение моторного масла и коррозию внутренних компонентов. Спроектированный для высокой эффективности и минимального падения давления, этот элемент обеспечивает более чистые выбросы из картера и способствует увеличению срока службы двигателя. Особенно важен в условиях высокой влажности и морской среды, где накопление конденсата представляет постоянную угрозу.
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.
