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.

In Situ Crankshaft Grinding | Onsite Services | Innovative Repairs | Bangladesh

When it comes to maintaining engine performance, the crankshaft is the most important component. Found in marine vessels, power plants, and heavy machinery, it’s a crucial part of the engine. But when it gets damaged or worn out, it can bring operations to a screeching halt, leading to expensive repairs and downtime. Traditionally, fixing a crankshaft meant removing it entirely— a process that’s time-consuming, costly, and a logistical headache. RA Power Solutions is a global leader in crankshaft repair, which has brought its revolutionary in situ crankshaft grinding technology to Bangladesh. This innovative solution is changing the game for industries across the country.

What is In Situ Crankshaft Grinding?

In simple terms, in situ crankshaft grinding is a way to repair crankshafts without taking them out of the engine. Instead of dismantling the entire machine and sending the crankshaft to a workshop, the repair is done right where the equipment is located. Using specialized portable grinding machines, technicians can restore the crankshaft’s journals (the smooth, polished surfaces that connect to other engine parts) to their original size and finish. This ensures the engine runs smoothly and extends its lifespan, all without the hassle of removal.

Why RA Power Solutions Stands Out

RA Power Solutions is a trusted name in the world of crankshaft repair, with 4 decades of experience and a reputation for excellence. The company has brought its expertise to Bangladesh, offering in situ crankshaft grinding services to industries like shipping, power generation, and manufacturing. Their team of skilled technicians uses advanced crankshaft grinding machines to deliver repairs that meet or exceed OEM (Original Equipment Manufacturer) standards. This is especially valuable in Bangladesh, where industries often face logistical challenges and need quick, cost-effective solutions to keep operations running.

The Benefits of In Situ Crankshaft Grinding:

Less Downtime, More Productivity:

Since the crankshaft doesn’t need to be removed, repairs are completed much faster. This means less downtime for businesses and more time for productivity.

Precision Repairs:

RA Power Solutions uses cutting-edge technology to ensure the crankshaft is restored to its original specifications. This precision ensures the engine performs at its best and lasts longer.

On-Site Convenience:

Whether it’s a remote power plant or a ship docked at a port. RA Power Solutions can bring its portable grinding machines to the site. This flexibility is a huge advantage for industries in hard-to-reach locations.

One standout example of RA Power Solutions’ impact in Bangladesh is their work with a major power plant. The plant’s crankshaft had worn down over the years of use, threatening to shut down power generation. Instead of going through the lengthy and expensive process of removing the crankshaft. RA Power Solutions’ team performed in situ grinding onsite. They restored the crankshaft to its original condition, ensuring the plant could continue operating without interruption. This not only saved the plant from costly downtime but also demonstrated the effectiveness of in situ grinding in real-world scenarios.

As industries in Bangladesh continue to grow, the demand for efficient and reliable maintenance solutions is on the rise. In situ crankshaft grinding is perfectly positioned to meet this demand. RA Power Solutions, with its advanced technology and experienced team, is leading the charge. By adopting this innovative technique, businesses in Bangladesh can reduce repair costs, minimize downtime, and keep their operations running smoothly.

The onsite crankshaft repair and grinding is undertaken by RA Power Solutions’ experienced technicians for diameters ranging from 30 mm to 700 mm, which covers almost all the crankshafts used for different applications. It is generally observed that due to non-experience or lack of knowledge of the companies undertaking crankshaft reconditioning and Onsite Crankshaft Machining, Crankshaft misguides the end user, resulting in serious breakdown and considerably higher expense.

Onsite Grinding of Crankpin by RA Power Solutions

RA Power Solutions has undertaken the reconditioning of crankshafts exceeding ten thousand numbers and recommends the following situation for the reconditioning of the crankshaft.

Recommendation for reconditioning of Crankshaft:

I) It is recommended to undertake crankshaft repair in case taper and ovality exceed the limit specified in the maintenance manual of the engine manufacturer.
II) In case of an accident, deep line marks or depression are developed.
III) Reconditioning of the crankshaft is recommended in case higher hardness is observed due to the seizure of bearings or any other reason.
IV) Development of surface crack.
V) Loss of alignment.
VI) In certain cases, although the dimensions of the CR Pin and Main Journal are observed within the limit, due to the rough surface observed on the CR Pin and of the Main Journal, the surface requires polishing.

The above suggestions are given for the reconditioning of the crankshaft. It is always advisable to send photographs and a brief Inspection report to RA Power Solutions for free recommendations as to how to repair the Crankshaft successfully.
