The bolt marked K 28034 is a specially engineered fastener designed for securing the main rocker arm (K 28005) in the ZV40/48 engine. This bolt must withstand dynamic mechanical loads, thermal fluctuations, and vibrations encountered during valve operation. Manufactured from high-strength alloy steel and precision-machined for perfect fit and tension, it plays a vital role in ensuring stable rocker arm performance. Its reliability is crucial for maintaining accurate valve timing and reducing mechanical stress on the valvetrain.
The O-ring coded K 28045 is a specialized sealing component used with flange K 28030 in the ZV40/48 diesel engine. Designed to provide a tight, leak-free seal in high-pressure and high-temperature environments, this elastomeric ring prevents oil or gas escape from the flange connection. Its flexibility, resistance to thermal expansion, and chemical durability make it indispensable for maintaining internal system pressure and preventing operational losses. As part of the engine’s sealing network, it supports overall performance and reliability.
The cover with code K 27007 is a crucial protective component paired with the bearing casing K 28000 in the ZV40/48 diesel engine. It shields internal bearing assemblies from contaminants such as dust, oil mist, and moisture while retaining lubrication within the casing. Engineered from corrosion-resistant materials and precisely machined, the cover ensures structural integrity, minimizes wear, and helps maintain the alignment of rotating components. This essential part contributes significantly to the engine’s durability and reduces maintenance needs over long service intervals.
Jacketed packing rings with code EN14U2429 are advanced sealing elements used in critical areas of the MAN L21/31 engine where high-performance sealing is required. Featuring a soft core (often graphite or PTFE) surrounded by a durable metal jacket, these rings combine flexibility with strength, adapting to surface imperfections while resisting extreme heat and pressure. They are commonly installed in exhaust, cylinder, or high-pressure sealing areas, ensuring leak-proof performance and long-term durability.
The oval packing, code EN14DB029052, is a specially shaped sealing element designed for the MAN L21/31 engine to ensure a tight fit between mating surfaces. Often used in valve housings or flanged joints, its oval geometry provides superior surface contact, enhancing its ability to prevent oil, fuel, or gas leaks under variable loads. Its resilience to heat, pressure, and chemical exposure makes it a key component in maintaining engine reliability and environmental safety.
Plug screws with code EN47AR10 are essential sealing and closure components within the MAN L21/31 engine. Typically used to block access points, inspection holes, or internal fluid pathways, these screws are engineered to withstand high pressure and temperature fluctuations. Their robust, corrosion-resistant construction ensures a tight and lasting seal, contributing to engine integrity and preventing fluid leaks during demanding marine or industrial operation.
