Crankshaft Repair of Wartsila Engine Model 16V32LN in East Africa

A leading Power supply company based in East Africa called  upon RA Power Solutions to immediately depute the technicians for the repair of crankshaft of wartsila 16V32LN diesel Generating set.  

The power supply company based in East Africa has a number of diesel driven power plants from where they supply the electricity to the utilities like hospitals, airports, public places and for domestic consumption. The diesel power plants have wartsila diesel generating sets models 12V32 LN, 16V32 LN, 6R32 & 9L20 which operate continuously.

Our senior technicians with an onsite crankshaft grinding machine were deputed to the site. The onsite crankshaft grinding equipment used by RA Power Solutions is designed & manufactured by us.

After extensive research, development, and our experience, We are successful to keep the weight of equipment low which facilitates our technicians to carry the tooling all over the world as accompanied baggage and no time is wasted in sending the crankshaft grinding machine by cargo, which of course is time-consuming.   

On inspection of the crankshaft, It was observed that three crankpins having a standard diameter of 270 mm were damaged due to seizure of the bearing. In the case of one crankpin, Radius fillet was damaged on both sides.

After undertaking the initial inspection of the crankpins including dimensions, crack detection, hardness, deflection, etc as per RA Power protocol, The grinding of the damaged crankpins was executed. All three crankpins diameter was reduced by 1.00 mm to the size of 269.00 mm against the standard size of 270 mm.

After grinding the assembly of the Wartsila engine 16V32 LN was undertaken by the Power plant technicians. All clearances were checked as per the Wartsila maintenance manual and found satisfactory. The engine was put into operation successfully.
