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

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.
