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.

MAN L21/31; HEXAGON SCREW (Code EN61V1230)

Written by

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.
