The cylindrical pin K 34117 is a precision positioning and fastening component designed for assembly K 34110 in the Sulzer ZV40/48 engine. Its primary function is to accurately locate and securely retain connected components while ensuring proper alignment under continuous operating loads. Manufactured from high-strength, precision-hardened steel, the pin is engineered to withstand shear forces, vibration, repeated cyclic loading, and demanding marine and industrial operating conditions without deformation or loss of dimensional accuracy. Precision machining guarantees an exact fit and reliable load transfer, minimizing movement between mating components and reducing mechanical wear. By maintaining assembly integrity and precise positioning, the K 34117 cylindrical pin contributes to smooth mechanical operation, increased component durability, and long-term engine reliability.
