Repair of MAN B&W Model 5L 16-24 by Using Onsite Crankshaft Grinding Machine

MAN Engine Model no. 5L 16/24 is a very common installation on vessels and the engine is used as Generator. The Crank Pin diameter of MAN Engine Model no. 5L 16/24 is only 130mm and the bearing width is 56 mm. In other words, it is about 2 inches 

This makes the onsite crankshaft repair very difficult due to limited space in between the two webs. Most onsite crankshaft repair companies based in Europe don’t have the equipment and the technology to undertake grinding/ repair of crankpin of MAN Engine Model no 5L 16/24. The repair companies always suggest to remove it from the engine block and send it to workshop for crank pin grinding or reject the crankshaft.

We successfully executed the repair of the crankshaft of MAN Engine Model no. 5L 16/24. Details are as mentioned below:
