In situ crankshaft grinding is a proven repair method that restores damaged crankpins and main journals without removing the crankshaft from the engine. RA Power Solutions has been providing this specialized service for more than 47 years, helping marine, power generation, offshore, and industrial operators minimize downtime and avoid costly crankshaft replacement. Our engineers use portable onsite crankshaft grinding machines that are mounted directly on the journal, allowing precision grinding while maintaining the crankshaft's original alignment and the engine manufacturer's specified dimensions. Every repair includes detailed inspection, dimensional measurement, controlled grinding, polishing, and final verification to ensure reliable bearing performance and long service life. With over 10,000 successful crankshaft repairs completed in 90+ countries, RA Power Solutions also offers onsite crankshaft grinding, crankshaft repair, crankpin repair, crankshaft polishing, line boring, metal stitching, and engine overhauling services, delivering complete onsite machining solutions for marine and industrial engines worldwide.

When a crankshaft gets damaged, people often think it's a big problem and that they need to replace the whole thing. But that's not always the case. If the damage is only on the crankpin or main journal and it's not too bad, some services can fix it. These services can grind the crankshaft and make it good as new so the engine can run normally again. This way, you save time and money, and you don't have to throw away the old crankshaft. It's a good option if you want to avoid replacing the whole thing.

When Is Crankshaft Grinding a Better Choice?

Replacing a crankshaft is a major job—it usually means taking the whole engine apart, pulling out the old crankshaft, sending it off to a workshop, and then putting in a new one. And let's be real, it's not just the cost that's a problem – the whole process can keep your engine out of commission for days or even weeks.

When you need to fix a damaged crankshaft, you can do it right where it is, without taking it out of the engine. This process is called crankshaft grinding repair, and it uses special portable equipment that you can take to the site. Because the crankshaft stays in the engine, you don't have to do as much work to take it apart, and the equipment can be up and running again much faster.

How Is the Repair Carried Out?

Before any work is done on the crankshaft, it's thoroughly examined. The team checks the journal diameter, taper, ovality, surface condition, and bearing damage to see if grinding is even an option. Once they've finished inspecting, they start grinding the damaged journal, but they do it gradually, taking it down to the next approved undersize. After that, they polish it to achieve the surface finish just right. The whole time they're working on the repair, they're taking measurements to make sure the journal dimensions stay within the limits set by the engine manufacturer. This way, they can be sure the crankshaft will work properly once it's all fixed.

A Practical Solution for Heavy-Duty Engines

Crankshaft grinding repair is widely used on marine propulsion engines, auxiliary diesel generators, compressors, power plant engines, mining equipment, and other heavy industrial machinery. For operators, the biggest advantage is reduced downtime. Instead of waiting for a replacement crankshaft, the existing component can often be restored and put back into service in a much shorter time.

For over 47 years, RA Power Solutions has been helping customers all around the world with crankshaft grinding repair. Our team has fixed more than 10,000 crankshafts, so we really know what we're doing. We use special machines to make the crankshafts good as new, right where they are. We don't just do crankshaft grinding, though – we also offer other services like polishing, line boring, and more. We can even come to you and do the work on site, which is really helpful for people in the marine and industrial sectors. Our engineers are super experienced and can handle all sorts of machining jobs, so you can trust us to get the work done right.

When a massive diesel engine breaks down on a vessel or in a power plant, every hour of lost productivity costs thousands of dollars. Traditionally, fixing a damaged crankshaft meant a complete engine teardown, pulling the heavy part out, and shipping it to a workshop. This old method takes weeks and costs a fortune.

Today, industrial plants and shipping companies worldwide rely on mobile engineering experts to solve these problems right where they happen. Onsite crankshaft grinding services bring the machine shop directly to your engine, getting your operations back up and running in record time.

Understanding On Site Crankshaft Repair

Over time, heavy continuous use causes engine components to wear down. Crankshafts can develop deep scratches, suffer heat damage, or lose their perfect round shape.

Instead of dismantling the entire setup, technicians now use advanced, portable equipment to perform on site crankshaft repair. These compact machines are designed to mount directly onto the damaged shaft inside the engine block. Specialized engineers then machine the metal back to factory-certified dimensions with extreme precision.

The Power of InSitu Crankshaft Grinding

In industrial engineering, "InSitu" means performing a task right in its original position. Choosing InSitu crankshaft grinding offers massive operational advantages:

Zero Transport Hassles: You do not have to worry about the logistics or high costs of shipping heavy freight.

Massive Time Savings: Skipping the teardown and reassembly phases cuts repair times from weeks down to just a few days.

Lower Budgets: Fewer man-hours and no shipping fees mean a much healthier bottom line for your business.

Flawless Accuracy: Portable grinding tools achieve the exact same microscopic tolerances as massive stationary workshop machines.

When to Use Crankshaft Polishing Services

Heavy grinding isn't always necessary. If an inspection shows only minor surface scratches, rough spots, or superficial blemishes, crankshaft polishing services are the quickest and most practical solution.

Using ultra-fine abrasive materials, technicians polish the metal surface until it achieves a mirror-like finish. This smooth surface reduces operating friction, protects the bearings from premature wear, and significantly extends the overall life of your engine.
