A vessel sailing near Oman reported a serious breakdown of the auxiliary engine of the Yanmar model 6N18AL. Our team, which is always ready for emergency response, left for Oman and conducted a detailed inspection of the engine. During grinding of the crankshaft, it was observed that crankpin no. 4 bearing seized, resulting in the damage of crankpin no. 4. All other crankpins also developed ovality to the extent of a maximum 0.20 mm. All the parameters like taper, ovality, surface finish, etc. after crankshaft grinding are maintained strictly as per the manufacturer’s specifications.
