Action Taken By RA Power Solutions For Repair of Crankshaft Yanmar 8N 330L EV

i) Since the vessel was anchored near Panama Port, RA Power Solutions deputed two technicians having a valid US VISA and Seaman book. Both technicians flew to Panama along with onsite crankshaft grinding machine and measuring instruments and boarded the vessel within 48 hours of the client’s first information of the breakdown of crankshaft of Yanmar 8N 330L EV.

The Details of Engine / Crankpin are as following:

ii) RA Power Solutions technicians inspected all the crankpins (8 Nos) to check the taper & ovality, the dimensions of observed are pasted below.

iii) On going through the readings, it was observed that the crankpin number #02 has developed excessive ovality of 0.43 MM, against the tolerance of 260.00 MM + 0.03 MM. This is considered very much on the higher side. All other crankpins also have ovality ranging from 0.09 MM to 0.10 MM, The bearing line marks and rough surface on the crankpin were observed.

iv) As a Protocol, hardness was checked of eight (8 Nos) Crankpins and was observed within limits.

v) Crack detection was also conducted, and no crack was observed on damaged crankpin number #02 and other crankpins.

vi) It was jointly decided to undertake the grinding of crankpin number #02 and polishing the remaining crankpins to remove the bearing line marks and to improve the surface finish.

vii) Although in the crankpin numbers #01,#03,#04,#05,#06,#07, and #08 the ovality was observed on the higher side as 0.10 MM, however, this was accepted under divation.

viii) The Crankpin number #02 was undersized by 1.5 MM, A Final Dimensional Report after grinding and polishing of crankpins of Yanmar 8N 330L EV is pasted below.

ix) In order to assist ship staff, our technicians undertook the dimensional and MPI Inspection of connecting rods available on the vessel, they were observed within limits.

The engine was commissioned during the presence of our technicians on the vessel.

RA Power Solutions is a leading onsite crankshaft repair company, extending services for over 44 years all over the world. We understand the requirement of standard and undersize bearings especially after the grinding of the crankshaft is executed it is difficult to get the undersize bearings, as their delivery period is long and it is not possible for the ship owner to hold the vessel indefinitely.

RA Power Solutions in order to facilitate clients, especially from the shipping industries, maintain a large stock of crankpin/main journal bearings. The bearings are available with us in different undersizes, as recommended by the manufacturer.

In most cases, our technicians hand carry the undersize bearings with them and the same are assembled immediately after grinding of the damaged crankshaft is undertaken, this saves breakdown time. The bearings of most of the popular make and models are available.

A list of a Few Models is given below:

We regularly supply engine bearings for crankpins, tri-metal bearings, engine tri-metal bearings, and bearings for all makes and models of engines like Yanmar, Daihatsu, MAK, MAN B&W, etc.
