The sealing element coded K 27054 is designed to provide an airtight and fluid-tight seal for handle K 27008 in the ZV40/48 diesel engine. This component prevents leakage of oil, fuel, or air around manually operated components such as valves or access ports. Engineered from durable elastomeric or composite sealing materials, it resists wear, temperature fluctuations, and chemical degradation. A reliable seal like K 27054 helps maintain internal pressure integrity, reduces maintenance needs, and protects the engine from contamination and performance loss.
The spring plate with code K 27205 is a vital component in the fuel injection valve assembly of the ZV40/48 engine. Positioned to support and stabilize the injector spring, it ensures correct tensioning and proper valve actuation. Its flat, robust design allows it to absorb repeated stress without deformation, maintaining consistent injection timing. The spring plate’s precision manufacturing contributes to balanced fuel delivery, smoother engine performance, and reduced emissions, making it indispensable in the injection system’s long-term operation.
The nut coded K 27209 is a small but essential fastening element in the fuel injection system of the ZV40/48 diesel engine. Specifically designed to secure the fuel injection valve in place, this nut ensures a tight and stable connection capable of withstanding extreme pressure and vibration during engine operation. Made from high-grade, corrosion-resistant steel, it maintains the structural integrity of the fuel delivery system and plays a critical role in preserving injection precision, combustion efficiency, and long-term engine reliability.
The assembly spray nozzles, code 11.01213-0063.0, play a crucial role in the lubrication and cooling systems of the MAN L21/31 engine. Strategically positioned, these nozzles deliver fine, pressurized streams of oil or coolant to targeted areas such as pistons, cylinder walls, or valve assemblies. Their precise flow helps regulate temperature, minimize friction, and extend component life, making them indispensable for efficient and long-lasting engine performance.
The closing cover with code 11.01288-0075.B is a critical sealing component for the MAN L21/31 engine, used to enclose access points or internal chambers. Designed to resist oil pressure, temperature, and environmental contaminants, this cover ensures safe containment of fluids and prevents mechanical ingress. Its role in maintaining a sealed and controlled environment inside the engine contributes directly to operational reliability and reduced maintenance frequency.
The retaining rings, code EN3N108, are essential securing components used in fine boring operations within the MAN L21/31 engine. These rings are precision-engineered to hold key internal elements in position during machining or assembly, ensuring consistent tolerances and mechanical integrity. Their robust construction allows them to resist deformation and vibration, contributing to the accuracy and durability of bored interfaces—especially in high-performance marine engine applications.
