The mounting of the double gearwheel is a critical assembly in the MAN L21/31 engine’s timing system. This component secures and supports the double gearwheel, which plays a key role in transmitting rotational motion between gears for precise synchronization of engine components. Proper installation and maintenance of this mounting ensure the reliable operation and longevity of the timing mechanism.
Dvostruki konusni stezni prsten, označen šifrom K 27503, ima ključnu ulogu u učvršćivanju sklopa usisnog ventila motora Sulzer ZV40/48. Konusni oblik omogućuje ravnomjernu raspodjelu sile oko stabljike ventila, čime se osigurava pouzdano i čvrsto brtvljenje pod visokim temperaturama i tlakovima. Konstrukcija u dva dijela omogućuje lakšu montažu i demontažu, što značajno olakšava održavanje. Ova komponenta je neophodna za osiguranje performansi motora, brtvenog učinka i dugotrajnosti rada.
The locking screw marked as K 73033 is a seemingly small but indispensable element in the secure fastening of the cooling water pump casing in the ZV40/48 engine. Designed to resist vibration and pressure fluctuations, this screw helps maintain a tight, leak-free seal around the pump housing. Precision manufacturing ensures it stays in place even during prolonged engine operation. By preventing coolant leakage and preserving pressure integrity, the locking screw contributes to the stability and efficiency of the engine’s cooling system.
The O-ring with code number K 27051 is specifically designed to seal the cylinder cover in the Sulzer ZV40/48 engine. Made from heat-resistant and pressure-resistant elastomer, this O-ring prevents the escape of combustion gases and protects the cylinder head assembly from fluid leaks. Its function is vital for maintaining compression and ensuring operational efficiency. A properly installed and maintained O-ring also minimizes wear and tear on surrounding components and supports engine longevity in harsh marine environments.
The two-part conical clamping ring, designated K 27503, plays a critical role in securing the inlet valve assembly of the Sulzer ZV40/48 diesel engine. Its conical design ensures uniform force distribution around the valve stem, allowing for reliable and tight seating of the valve under high-temperature and high-pressure conditions. The two-part construction allows for easier assembly and disassembly, making maintenance faster and more efficient. This component is essential for ensuring engine performance, sealing integrity, and operational longevity.
The intermediate wheel complete plays a key role in the MAN L21/31 engine’s timing system. It transmits rotational motion between gears within the timing gear train, ensuring accurate synchronization of the crankshaft and camshaft. This precise coordination is vital for maintaining correct valve timing, optimizing engine performance, and preventing mechanical failures.
