RA Power Solutions Pvt. Ltd. was called by a shipping company based in Indonesia reporting the failure of crank pins of Hyundai 1.8 MW diesel engine. Our technicians were deputed with portable crankshaft grinding machine designed and manufactured by us.
On arrival of our technicians it was observed that all the 6 CR pins of Hyundai engine were badly damaged due to failure of lubricating oil pump. The initial inspection of crank pins was conducted comprising of calibration for taper and ovality. Hardness test, crack detection by MPI and deflection checks were also done and recorded.
RA Power Solutions Pvt. Ltd. was successful in executing the on site crankshaft grinding of 6 nos. CR pins in short time of 72 hours. This achievement was possible because of the excellent design of onsite crankshaft grinding machine was developed and manufactured by RA Power solutions in house engineers. A pneumatic turbine with high capacity and latest design was used which helped technicians to execute the repairs in short duration.
