RA Power Solutions Pvt. Ltd. has offered in situ crankshaft repair and polishing services for over four decades. The crankshaft is the most important part for keeping the engine running properly. It is an essential component of engines in marine boats, power plants, and heavy machinery. However, when it becomes damaged or worn out, it can bring operations to a standstill, resulting in costly repairs and downtime. RA Power Solutions, a global pioneer in crankshaft maintenance, has introduced its breakthrough in situ crankshaft grinding technology to Bangladesh. This unique approach is changing the game for industries throughout the country.

With the insitu crankshaft grinding machine, our trained specialists can arrive at a site in the shortest amount of time and fix the crankshaft without removing it from the main engine.

Efficient crankshaft on the engine Restoration: 35 to 700 mm in diameter Grinding Accuracy

Since the crankshaft is the engine’s central component, it transforms reciprocating motion into the linear movement that powers the engine through the use of connecting rods. With the process, technology, and onsite crankshaft grinding equipment from RA Power Solutions, crankshaft repair is now feasible without removing the crankshaft from the engine. These machines range in size from 35 mm to 700 mm. Our technology can repair crankshafts up to 700 mm in diameter, allowing us to fix any crankshaft, regardless of its weight or length.

In general, the crankshaft has several applications, including diesel generators and marine engines. Typical areas of crankshaft applications are as follows:

Compressors
Power generators
Forging hammers
Pumps
Marine engines

FAQs

1. What sizes of crankshafts can you repair onsite?

Customers often want to know the diameter range your equipment handles. RA Power’s insitu grinding is capable of servicing crankpins from 35 mm up to 700 mm (even 50–700 mm) without engine removal.

2. How much downtime and cost savings are involved?

One of the top concerns: how in-situ grinding cuts downtime and expense. By avoiding full engine disassembly and shipping, companies save significantly on labor, transport, and workshop costs.

3. What precision and finish can you achieve?

Customers ask if the onsite process meets OEM specifications. The portable machines deliver precision within 10–25 µm and achieve surface finishes (Ra) that align with OEM standards.

4. Can you repair crankshafts while the engine is in operation or at sea?

A common need in marine and power-plant contexts. Yes—insitu grinding can be done on-vessel (even underway) or at power plants, offering portable, global 24/7 service.

5. What inspection and quality assurance processes do you use?

Customers want confirmation of quality control. Services typically include MPI/crack detection, hardness testing, surface roughness measurement, dimensional checks, vibration testing, ensuring journals are restored to spec.

Crankshaft Repair is important for engines running continuously. It is observed that the crankshaft, crankpin, and main journal develop taper and ovality after certain hours of operation. This needs crankshaft repair.

At RA Power Solutions, we offer advanced crankshaft repair services that restore crankshafts to original specifications with minimal downtime and maximum reliability. Our skilled engineers use portable, lightweight on-site crankshaft grinding and polishing machines that eliminate the need to remove the crankshaft from the engine, saving time, cost, and operational disruption.

Why Crankshaft Repair Matters

Over time, bearings wear and crankshaft journals develop rough surfaces and out-of-round conditions. These issues, if ignored, can result in:

Increased engine vibration
Reduced oil film formation
Higher fuel consumption
Costly breakdowns

With professional crankshaft repair, these problems are corrected before they lead to major failures. The crankshaft is ground and polished back to precise tolerances, restoring smooth surfaces and optimal engine performance.

Global Expertise & Reliable Execution

RA Power Solutions Pvt. Ltd. has associated with leading shipping companies and diesel power plants and has undertaken crankshaft repair and onboard crankshaft repair for more than 45 years. The company has successfully executed the repair of more than 10,000 crankshafts.
