Motor Shaft

Himsen Hyundai 6H17/28 crankshaft has been successfully repaired at MIP Mersin, Turkey. The vessel owned by an Italian company faced a major breakdown in one of their auxiliary engine, Himsen Hyundai 6H17/28.

RA Power Solutions was approached and deputed our two technicians along with onsite crankshaft grinding equipment. The vessel was anchored at MIP Mersin, Turkey.

Following are the major Engine and Crankpin details:Main Observations of Crankshaft of HIMSEN HYUNDAI 6H 17/28

i) On visual inspection, it was found that it was a case of lubricating oil pump failure, damaging the bearings of all connecting rods.

ii) The bearing material was found embedded on all six (6) crankpins and was carefully removed. After polishing the crankpins, the dimensional inspection was conducted. The taper, ovality ranging from 0.22 MM to 0.86 was observed.

iii) The hardness was checked and was found within limits, except for a few spots, which were found not harmful to the crankshaft.

iv) The crankpins were subject to a MPI test for crack detection and minor hairline cracks were observed, All other parameters were found within the limit.

Action Taken By RA Power Solutions Technicians For Damaged Crankpins:

i) The grinding of all six (6) crankpins was undertaken by our insitu crankshaft grinding machine.

ii) Three (3) number of crankpins diameter was reduced by 1.00 MM and the final size was maintained as 174.00 MM.

iii) Three (3) number of crankpins diameter was reduced by 1.50 MM and the final size was maintained at 173.50 MM.

We have been regularly executing on site crankshaft repairs and In Situ crankshaft grinding in Dubai, Fujairah, Qatar, Saudi Arabia, Oman, Iraq, Togo, Malta, Freetown, Egypt, Malaysia, Iran, Indonesia, Vietnam, Jordan, etc.

We have a team of trained technicians available 24/7 and can be deputed at short notice. Some of our technicians also have valid US VISA and can fly to South America, Caribbean countries, etc.

In Case of Long hours of Electric Motor operation  it is generally observed that the bearing sitting diameter of the Motor Shaft develop taper/ ovality and rough surface. This requires repair of the Motor Shaft by grinding and polishing.
RA power solutions have facility for  onsite repair of Motor shaft of all types and applications at best price.
The Motor Shaft bearing sitting diameter is repaired without disassembly of the heavy-duty and high capacity Motors.
We have a team of technicians and portable onsite grinding machines ranging from 35mm to 700mm in terms a diameter. The technicians with portable onsite repair machines are deputed to the site to conduct the inspection of diameter shaft and undertake the repair of grinding as per the requirement.
