The washer K 41146 is a precision fastening and load-distribution component used within the camshaft drive of the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Although relatively simple in design, it performs an important role by distributing fastening forces across the appropriate contact surface, supporting correct axial positioning, and helping maintain the mechanical integrity of the associated camshaft-drive assembly. During engine operation, the component is exposed to continuous vibration, cyclic mechanical loading, and temperature variations, making dimensional accuracy, adequate mechanical strength, and suitable surface condition essential for dependable service. A worn, damaged, or deformed washer can adversely affect fastening security, component positioning, and load distribution, potentially contributing to increased movement and wear of neighboring parts. Inspection of the K 41146 washer and its mating surfaces should therefore form part of appropriate camshaft-drive maintenance. By supporting secure fastening and uniform load transfer, the K 41146 washer contributes to accurate alignment, reduced mechanical wear, and reliable long-term operation of the ZV40/48 camshaft drive.
