RA Power Solutions Pvt. Ltd. strongly recommends periodical crankshaft polishing. The main advantages of crankshaft polishing are following:-

It is generally observed that crankpin and main journal after regular operation develop rough surface and bearing line marks. The onsite polishing removes the marks and improves the surface finish.

 Crankpin and main journal polishing results to control of taper and ovality to some extent.

On site crankpin and main journal polishing is now possible due to portable equipments available. RA Power Solutions Pvt. Ltd. suggests that whenever the engine is opened for overhaul, the crankpin should be calibrated and polished. The crankpin polishing always enhances the life of bearings and crankshaft.

REPAIRS UNDERTAKEN BY RA POWER SOLUTIONS FOR SUCCESSFUL OPERATION OF CRANKSHAFT OF YANMAR S185L-ST ENGINE:-

  • Initially the crank pin having a standard diameter of 140 mm and bearing width of only 62 mm was ground to 0.50 mm under size with a hope  the scratches and deep line marks will be removed.
  • Since even after grinding 0.50 mm, the deep line marks were clearly visible, it was decided to under size the crank pin further by 0.5 mm.

 

MAIN FEATURES OF EXECUTING SUCCESSFUL REPAIR OF  YANMAR S185L-ST ENGINE:-

  • A company has experience of more than four decades in the field of crankshaft repair having experienced technicians trained in in-house training school.
  • Manufactures its own on site crankshaft grinding machine using it for the last 25 years. This facilitates us even to grind shafts in limited space available.
  • Only company in the world which can undertake the grinding of small diameter and main journal like in case of Yanmar S185L-ST having a diameter of 140 mm and bearing length of only 62 mm. This really needs a compact on site crankshaft grinding machine.
  • Only company in the world which can execute the grinding of crankshaft while the vessel is on move maintaining the tolerance of 0.01/0.02 mm with surface finish of less than 20 RA value.
  • Maintaining under size and special size of bearings in stock, hence no time is wasted to put back the engine into operation.
  • All technicians having Indian CDC can fly to any destination in the world in a short notice.
  • The on site crankshaft grinding machine is carried by our technicians as an accompanied baggage and no need of booking the machine in cargo and wasting the time in custom clearance etc.
  • For reduction in cost of the maintenance and to put back engines into operation , contact us.

In the case of cylinder liners, the crack was repaired from the inside and from the outer diameter as well  by a metal lock process. We used special alloy locks and keys to repair the crack.

The two cracks in the engine block liner sitting area were repaired by a metal lock. After repairs, the proper grinding and polishing was done on the crack area to maintain the specified tolerance. The liners were assembled in the presence of our technicians and the engine was put on operation after leak test. The performance of the engine after crack repair of cylinder liners and engine block is observed satisfactory.

Successful Repair of Crankshaft with damaged Radius fillet due to accident.

It is observed that the leading companies in the world are not able to undertake the grinding of journals in case the radius fillet of the crank pin or main journal of the crankshaft is damaged. Their grinding tool is mounted on the radius fillet and all the references for grinding and polishing are taken from the fillet radius. 

In case of damage to the radius fillet it is not possible for them to use their outdated grinding equipment. They always insist for first repair of the radius fillet charging exorbitant and unreasonable amounts. This not only costs  very high  to the client but also holds the vessel.

RA Power Solutions has the onsite crankshaft grinding machine which is designed to undertake grinding and polishing of crank pin and main journal diameter having small bearing width.

In this case, the crank pin bearing width is only 64 mm which most of the companies based in Europe cannot execute the repair due to the want of the compact equipment.


The job of grinding was successfully executed by our technicians and engine is performing satisfactorily.


We have been regularly executing the repairs in 
Moldova, BelarusAustralia, Austria, Belgium, Brazil, Singapore, Dubai, Greece, Cambodia, Colombia, Denmark, Ethiopia, Ghana, Nigeria etc.
