The toothed wheel K 42110 is an important power-transmission and timing component associated with the camshaft of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Its primary function is to transmit rotational motion through the camshaft drive system while preserving the precise mechanical relationship required for correct synchronization of the camshaft with the engine operating cycle. Accurate tooth profile, pitch, concentricity, alignment, and running clearances are particularly important because progressive tooth wear, incorrect backlash, or misalignment can lead to irregular gear engagement, increased vibration and noise, and deterioration of timing accuracy. The K 42110 toothed wheel must withstand repeated tooth loading, continuous rotation, vibration, and extended heavy-duty service while operating under appropriate lubrication conditions. During maintenance and overhaul, the tooth flanks, bore and mounting surfaces, alignment, backlash, and lubrication condition should be inspected carefully for abnormal wear or damage. By providing accurate and reliable transmission of rotational movement to the camshaft, the K 42110 toothed wheel contributes to precise engine timing, smooth operation, reduced wear of associated drive components, and long-term reliability of the ZV40/48 engine.
