Action taken by RA Power Solutions to Repair Bergen Rolls Royce Crankshaft Model no. C 25:33 L9P

i) Before the arrival of our two technicians and  boarding on a vessel at Mumbai Port India, the ship staff removed all the connecting rods. 

ii) On visual inspection one number of crankpin was observed damaged having standard diameter of 230 mm and crank pin bearing width of 92 mm.

The minimum & maximum reading of crank pin was observed as following: 

   a) Minimum diameter observed-   229.61 mm

    b) Maximum diameter observed-  229.93 mm

Against the standard diameter of 230.00 mm the ovality of 0.32 mm was observed which is considered to be very much on the higher side. Deep bearing line Marks and rough surface was observed.

iii) All other crankpins were also subject to dimensional inspection, taper & ovality was observed within limits. Only the Bearing line marks were observed. 

iv) As a routine inspection the hardness of crankpin was inspected and was observed within limits. The crack detection was  also undertaken by MPI and no crack was observed. 

v) The grinding of one number of crank pin was undertaken maintaining the final size of 229.00 mm with undersize of 1.0 mm. 

vi) All other crankpins were polished for removal of bearing line marks. After polishing the surface finish of better than 0.15 RA Value was observed.
