Onsite Crankshaft Grinding in Singapore

Singapore, being one of the world’s busiest maritime hubs, demands engine components that perform flawlessly even under the harshest conditions. When a crankshaft develops wear, taper, ovality, or damage, traditional repair often requires removing the engine components, incurring heavy transport expenses, and resulting in costly downtime. In situ crankshaft grinding, also known as onsite crankshaft grinding, offers a smarter alternative. At RA Power Solutions, we specialize in insitu crankshaft grinding and crankshaft repair, delivering high precision, minimal disruption, and cost-effective solutions in Singapore.

What Is Onsite Crankshaft Grinding and Repair?

In situ crankshaft grinding means repairing the crankshaft’s main journals or crankpins without dismantling the engine or removing the crankshaft from its block. By using portable grinding and polishing machines, technicians restore worn or damaged surfaces to OEM standards. Crankshaft repair in this context encompasses grinding, polishing, inspection, and, if necessary, reconditioning of the crankshaft, all performed directly onsite.

Why Singapore Needs Insitu Crankshaft Grinding?

  • High Maritime Traffic and Tight Schedules: Vessels docked at Singapore cannot afford long engine-down periods. Onsite services reduce downtime drastically.
  • Industrial Engines and Power Plants: Many industries in Singapore operate heavy-duty diesel or marine engines; delaying repair causes huge production losses.
  • Cost and Logistics: Transporting crankshafts or engines overseas or even across regions involves heavy costs, customs, handling, etc. Onsite services avoid many of these expenses.

The crankshaft of Peroni Pump manufactured by Peroni Pompe Italy, was inspected by RA Power Solutions technicians for the following parameters:

  • Dimensional inspection of crankpin for taper & ovality. The ovality ranging from 0.06 mm to 0.18 mm was observed. 
  • The MPI test was conducted with a high-intensity Magnaflux torch and no abnormality was observed. Few superficial hairline cracks were observed, which may be due to rubbing of the crankshaft bearing steel lining with the crankpin diameter.
  • The hardness of the crankpin was observed within limits.
  • On visual inspection, bearing line marks and a rough surface was observed.
