The round seal ring, code 100100, is a sealing element used in the MAN L21/31 engine to prevent unwanted passage of fluids or gases between adjoining components and to maintain the required tightness of the relevant engine system. Its circular form allows the ring to provide continuous sealing around the connection, with compression between mating surfaces creating the barrier necessary to retain the operating medium. Depending on its installation position, it may be exposed to lubricating oil, fuel, cooling water, compressed air, temperature fluctuations, pressure changes, vibration, and mechanical movement. For this reason, the correct dimensions, material compatibility, surface condition, and installation procedure are essential for preventing premature wear, deformation, hardening, or loss of sealing performance. A correctly installed round seal ring helps minimize leakage and contamination, protects associated engine components, supports efficient maintenance, and contributes to the long-term reliability and operational safety of the MAN L21/31 engine.
The seal ring M20X26, code 100100, is a precision sealing component used in the MAN L21/31 engine to establish a reliable barrier at a connection where its specified M20X26 dimensions are required. Depending on the particular installation point, the seal ring may prevent leakage of lubricating oil, fuel, cooling water, compressed air, or another operating medium while also helping protect the surrounding system against contamination. During engine operation, the ring can be exposed to pressure variations, vibration, temperature changes, mechanical compression, and continuous contact with the relevant operating fluid, making dimensional accuracy and suitable material properties particularly important. Correct installation and appropriate tightening of the associated connection ensure that the ring is compressed as intended without being damaged or excessively deformed. By maintaining a dependable seal, the M20X26 seal ring helps prevent fluid losses, protects adjacent components, reduces maintenance requirements, and contributes to the safe and reliable operation of the MAN L21/31 engine.
The glue, code 195956, is a specialized bonding and securing material intended for use in the assembly, maintenance, and repair of components associated with the MAN L21/31 engine. Depending on the specific application, such an adhesive may be used to secure threaded or cylindrical connections, assist in sealing mating surfaces, prevent loosening caused by vibration, or provide additional retention between assembled components. In demanding marine and industrial engine environments, the selected adhesive must maintain its properties when exposed to temperature variations, vibration, lubricating oil, fuel, moisture, and other operating influences relevant to its installation location. Correct surface cleaning, preparation, application quantity, and curing conditions are essential for achieving a reliable bond. When applied according to the specified maintenance and assembly procedures, the glue helps improve connection security, reduce the possibility of leakage or loosening, simplify maintenance, and support the long-term operational reliability of the MAN L21/31 engine.
The journal pin K 41141 is a precision supporting and locating component used within the camshaft drive of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Its principal role is to provide an accurately positioned journal or bearing support for the associated rotating components of the camshaft drive, helping maintain their correct alignment and stable movement under operating loads. The journal pin must withstand repeated radial and mechanical forces, vibration, and prolonged contact with its corresponding bearing or bush surfaces while maintaining dimensional accuracy and an appropriate surface condition. Proper material strength, surface finish, lubrication, and installation are especially important because excessive wear or clearance at this location can lead to misalignment, irregular gear engagement, increased vibration, and accelerated wear of neighboring drive components. Inspection of the journal surface and associated bearing clearances is therefore an important consideration during camshaft drive maintenance. By providing stable and accurately located support for the drive mechanism, the K 41141 journal pin contributes to precise gear operation, correct camshaft timing, reduced mechanical wear, and dependable long-term operation of the ZV40/48 engine.
The toothed wheel K 41120 is an important power-transmission and timing component in the camshaft drive system of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Working as part of the engine's gear train, it transmits rotational motion required to drive the camshaft while maintaining the precise mechanical relationship necessary for correct timing of the engine's operating functions. The accuracy of the tooth profile, pitch, concentricity, alignment, and running clearances is particularly important because even progressive wear or incorrect gear engagement can increase vibration and noise and influence the accuracy of the camshaft drive. The K 41120 toothed wheel is designed to withstand repeated tooth loading, continuous rotation, vibration, and long periods of heavy-duty service under appropriate lubrication. Regular inspection of the tooth flanks, bearing surfaces, backlash, alignment, and lubrication condition helps identify abnormal wear before it affects the wider gear train. By providing accurate and dependable transmission of rotational motion, the K 41120 toothed wheel supports correct camshaft timing, smooth engine operation, and reliable long-term performance of the ZV40/48 engine.
The bush K 41113 is a precision bearing and guiding component designed for the toothed wheels K 41110 and K 41120 within the camshaft drive of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Its primary function is to provide a stable bearing surface that supports accurate rotation of the toothed wheels while reducing friction and protecting the associated shafts and gear components from excessive wear. During engine operation, the bush is subjected to continuous rotational movement, cyclic mechanical loads, vibration, and the demanding lubrication conditions characteristic of a heavy-duty camshaft drive. Accurate dimensions, correct clearances, suitable bearing material, and effective lubrication are therefore essential for maintaining proper gear alignment and smooth transmission of motion. Wear or excessive clearance in the bush can adversely affect gear engagement and increase vibration, noise, and loading on neighboring components. By maintaining precise support and alignment of the K 41110 and K 41120 toothed wheels, the K 41113 bush contributes to reliable camshaft drive operation, reduced component wear, correct engine timing, and long-term reliability of the ZV40/48 engine.
