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.

Crankshaft Reconditioning | Crankshaft Grinding Machine Exporter – RA Power Solutions

RA Power Solutions undertakes the repair of crankshafts having a diameter ranging from 35 mm to 700 mm. The concept of removing the crankshaft and sending it to the workshop for repair is now no longer valid, and the user gets the crankshaft repaired onsite.

During our working of more than forty years on marine main, crankshaft reconditioning, auxiliary engines, and high capacity diesel generating sets installed in industry, power plants, etc., we have observed that while the maintenance schedule stipulated by the engine manufacturer in the maintenance manual is religiously followed, but no attention is paid on the crankshaft’s condition.

Even during the maintenance schedule of 25,000 to 30,000 hours of operation, maintenance agencies and officials connected with the day-to-day upkeep of the engine ignore the inspection of the crankshaft till the seizure of the bearing or any other major breakdown happens in the crankshaft.

**Repair of Crankpin on Board a Vessel**

We have experienced that irrespective of the metallurgy of the crankshaft and level of hardness after continuous operation of the engine, taper and ovality of the crankshaft, crankpin, and main journal are developed. The bearing surface becomes rough, and in some cases, bearing line marks, pitting, etc., are developed. Due to these abnormalities developed in the crankshaft, failure of the bearing and the crankshaft takes place. RA Power Solutions recommends that inspection procedures be followed to ensure satisfactory performance of the crankshaft and to save it from rejection.

During the periodic maintenance schedule, the crankpins and main journals of the crankshaft should be checked for the development of taper and ovality.
The dimensions of the crankpin, taper, and ovality should be well within the limits specified by the manufacturers. There should not be any presence of bearing line marks or pitting on the crankpin journals.
The profile of the lubricating oil hole and radius fillet should be checked visually. There should not be any loss of the original profile.
The hardness test and the crack detection test by MPI or dye penetrant are not required till the major failure of the bearing or accident takes place.

Inspection of Crankpin on Board a Vessel

Checking of deflection of the crankshaft.
Positioning of crankshaft balancing weights. They should be tightened to a specific torque as per the manual.

In case the above preventive inspection is undertaken on-site without disassembly of the crankshaft, the user can avoid any major damage to the crankshaft.

On-site machining of crankpins and main journals has been made simple in this era of technological renovation. The concept of removing the crankshaft and getting the crankshaft machined in the workshop is no longer valid. The onsite crankshaft machining is undertaken to maintain strictly all the tolerances as specified by the manufacturer and stipulated in the maintenance manual.

Crankshaft machining is no longer the monopoly of a bunch of companies based in Europe and the UK. The availability of a portable, easy-to-operate crankshaft grinding machine has made it simple and easy to undertake the polishing and grinding of the main journal if required.
