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.
