The sealing element with code 16113 is a specialized gasket designed to ensure tightness between components K 16110 and K 16114 in the ZV40/48 diesel engine assembly. Positioned at a critical junction in the engine’s fluid or pressure system, this seal prevents leakage of oil, air, or combustion gases, depending on its application. Made from high-quality, temperature- and pressure-resistant materials, the sealing ensures durability under cyclic loading and thermal expansion. Its effectiveness is essential to maintaining system integrity and supporting efficient engine operation without downtime due to leakage.
The ball-shaped cup coded K 28041 is a key interface element in the rocker arm assembly of the ZV40/48 diesel engine. Designed to provide a smooth contact surface between the pushrod or adjustment screw and the rocker arm, it accommodates slight angular movements while minimizing friction and wear. Its spherical shape allows for even distribution of force, reducing stress concentrations and extending component life. Precision-manufactured from hardened materials, this cup ensures quiet, smooth rocker arm operation and contributes to the longevity of the valve gear system.
The shaft with code K 28025 is specifically designed to support and align the main rocker arm (K 28005) within the ZV40/48 engine. This robust shaft acts as a pivot point for the rocker arm, allowing it to transfer motion from the camshaft to the valves with mechanical precision. Built from hardened, wear-resistant steel, it must withstand constant mechanical stress and thermal cycling. Its proper function is essential for maintaining accurate valve timing and reducing wear in the valve train, directly affecting engine efficiency and reliability over time.
The nipple coded K 27752 is a small but essential component that facilitates the connection of an indicator valve to the ZV40/48 diesel engine. Used primarily during performance diagnostics, this nipple provides a secure and pressure-tight interface through which cylinder pressure readings can be obtained in real time. Manufactured from high-strength, heat-resistant materials, it ensures safe operation even under high combustion pressures. Its role is critical during engine tuning, maintenance, and troubleshooting, as it enables precise monitoring of in-cylinder conditions without disassembly.
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 complete damper end cover with code K 16500 is an integral part of the engine’s vibration dampening system, located at the far end of the crankshaft in the ZV40/48 engine. This component encloses the torsional damper mechanism, protecting it from mechanical damage and environmental exposure. Designed to withstand the effects of rotating mass forces, heat, and oil exposure, the cover ensures the proper functioning of the damper, which reduces engine vibration and mechanical stress. Its robust construction contributes to smoother engine operation and extends the life of connected rotating assemblies.
The ring coded K 27010 is a specially designed support and locking element used in combination with component K 27008 in the ZV40/48 engine assembly. It ensures secure positioning and mechanical stability of the mating part, particularly under dynamic engine conditions involving vibration, thermal expansion, or pressure fluctuations. Manufactured with tight tolerances and wear-resistant materials, this ring plays an important role in maintaining sealing integrity and axial alignment. Its durable construction helps extend the lifespan of the assembly and supports reliable engine operation in harsh industrial and marine environments.
