The thrust washer K 43162 is a precision load-bearing and positioning component designed for the starting device associated with housing K 43161 on the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 engine. Its primary function is to absorb and distribute axial forces generated within the starting mechanism while maintaining the correct axial relationship and controlled movement of the associated components. Although relatively simple in form, the thrust washer performs an important protective function by providing a defined contact surface between components, helping prevent direct wear of more substantial parts and supporting stable operation during repeated starting cycles. The K 43162 must therefore maintain accurate thickness, flatness, surface condition, and adequate resistance to wear under cyclic loading, vibration, and repeated mechanical contact. During maintenance or overhaul, the washer and its mating surfaces should be inspected for scoring, excessive wear, deformation, cracking, overheating, or other damage that could alter axial clearance or load distribution. By controlling axial loads and preserving the correct positioning of the starting-device components, the K 43162 thrust washer contributes to smooth mechanical operation, reduced wear, reliable starting performance, and extended service life of the K 43161 starting-device assembly.
