RA Power Solutions is a global leader in insitu crankshaft grinding and repair services, with a strong presence at Singapore Port. Known as one of the busiest maritime hubs in the world, Singapore demands fast, reliable, and professional marine repair solutions. RA Power Solutions provides onsite crankshaft grinding in Singapore, ensuring minimal downtime and maximum efficiency for vessels and industries operating in this vital region.
Why Engines Need In Situ Crankshaft Grinding?
Over time, crankshafts face wear and tear due to:
- Continuous operation under heavy loads
- Not enough lubrication or the oil film breaking
- Accidental overloads or sudden stoppages
- Metal fatigue and surface damage
If you don’t repair these problems, they will cause the engine to fail. In situ crankshaft grinding restores the shape, gets rid of ovality, and polishes the surface to OEM tolerances.
Advantages of In Situ Crankshaft Grinding

| High-Quality Outcomes | Compliance with or beyond OEM accuracy (taper, ovality, surface finish) |

Case Study: Saving a Marine Engine
A shipping company faced an emergency when its main engine crankpin developed cracks mid-voyage. Instead of costly engine removal, RA Power Solutions sent an in situ grinding team onboard. Within 48 hours, the crankpin was ground undersize, fitted with new bearings, and the vessel resumed service. This saved weeks of downtime and thousands of dollars.
