The O-ring coded K 11126 is a compact yet vital sealing component used with ring K 11116 in the Sulzer ZV40/48 engine. It provides a flexible and leak-proof interface in assemblies exposed to high pressure or thermal cycling. Engineered from resilient elastomeric material, the O-ring maintains its shape and function over extended operational periods, resisting wear, compression, and chemical degradation. Its role is fundamental to preserving internal sealing performance, particularly in fuel, oil, or air systems where tight containment is critical.

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.
