RA Power Solutions has recently repaired a crankshaft of Yanmar Engine 6N165 at Mumbai Port India.

The major technical details of the crankshaft of Yanmar 6N165 are as follows:

S. NO	Crankshaft Details
1.	Engine Make	YANMAR
2.	Engine Model	6N165
3.	Crank pin Diameter Standard	125 mm
4.	Crankpin Bearing Width	48 mm
5.	Place of execution of crankshaft repair	At port Mumbai

Our technicians boarded the vessel and came to know that two local companies were engaged by the vessel owner to undertake the grinding of one number crankpin which was damaged. Both companies due to the non-availability of necessary tooling further damaged the crankpin and were not able to undertake the crankpin grinding.

As mentioned above the crankpin diameter of Yanmar Engine 6N165 is 125 mm and the crankpin bearing width is only 48 mm, in order to undertake the grinding of a crankpin having such a small crankpin width a very compact crankshaft grinding tool is required which no other company in the world posses.

RA Power Solutions with forty-four years of experience in the field of crankshaft repair has developed a compact and dedicated tooling that is inserted from the inspection window and is placed on the crankpin with the latest technology and process followed by us. The crank pin grinding is executed. In this case, since the crankpin was badly damaged by the local grinding company engaged by the vessel owner, we had no option but to undertake grinding to 4.0 mm undersize. The bearing was supplied by RA Power Solutions and the engine is performing satisfactorily.
