Certainly, you have read that correctly. No disassembly. There is no shipping available. There is no need to wait for weeks.

What distinguishes RA Power Solutions?

They possess a fleet of in situ crankshaft grinding machines that are portable, compact, and designed to perform precise repairs at your location. This service is available whether you are on a marine vessel in the middle of the ocean or at a power plant that cannot shut down.
These devices accommodate crankshaft diameters ranging from 35 mm to 700 mm. That essentially encompasses the majority of auxiliary and main engines utilized in heavy industry, mining, power plants, and shipping.

Why In Situ Crankshaft Grinding Is a Smart Choice

• No disassembly is required.

• Beware of the antiquated approach that necessitates the complete removal of the crankshaft and its transportation to a workshop.
• The portable machine penetrates the engine block through the inspection window and completes the task immediately.

• Significant time saving

• Repairs that have historically required weeks?
• The team can resolve specific crankshaft issues in as little as 24 hours with RA Power Solutions—prompt turnaround results in minimal downtime.

• Extremely cost-effective

• There are no logistics expenses.
• There is no charge for reinstallation.
• No production revenue was lost while the crankshaft was awaiting its return from the workshop.
• A rapid resolution results in a reduction in expenditures.

• Precision equivalent to that of the original equipment

1. The crankpin is precisely restored to the OEM tolerance through the crankshaft grinding and polishing procedure.
2. The surface quality has been enhanced to 0.2 micron Ra, which translates to smooth AF.
3. It is also possible to polish and refine.
4. Polishing/honing can be performed without the need for full grinding if the crankpin has minor damage or if a surface finish enhancement is required.

Real Results. Real Experience.

This is not a novel concept for RA Power Solutions. For more than 45 years, they have been servicing engines on a global scale, including those in factories, power plants, and ships.
They did not merely perfect the process; they also constructed their own onsite crankshaft milling machine and have already sold over 70 units worldwide.
The most intriguing aspect is that they provide complementary training to the client’s technicians during the project, ensuring that your team is fully informed about the situation.

Power plant officials were advised to open all the connecting rods and visually inspect the crankpins of the Wartsila 9L20. Damage to crankpin number #09 was reported. On going through the photographs of the damaged crankpin, the radius fillet on both sides of crankpin number #09 was observed to be damaged.

RA Power Solutions‘ two (2) technicians, along with an onsite crankshaft grinding machine, were deputed from our plant in New Delhi. The details of the engine and crankshaft are as follows:

Action Taken by RA Power Solutions to Repair the Crankshaft of Wartsila 9L20 in Madagascar, East Africa

i) RA Power technicians followed a standard inspection protocol, during which the damaged crankpin number 9 was subjected to a dimensional check, crack detection by MPI, hardness check, etc. A pre-inspection report was prepared.

ii) On inspection of crankpin #09, excessive ovality of 0.41 mm was observed against the specified limit of 0.03 mm. The dimensional report is pasted below. Technicians also observed bearing line marks on the crankpin.

iii) RA Power Solutions carried out the repair by undersizing crankpin #09 of the Wartsila 9L20 by 1.00 mm, as the power plant had a 1.00 mm undersized bearing available. The engine was successfully commissioned in the presence of our technicians.

iv) The onsite crankshaft grinding machine, developed and manufactured by RA Power Solutions, is of the latest design and maintains a tolerance within 0.02 mm (20 microns) after grinding. The surface finish achieved is of a very high standard—15 RA value or less—which is highly recommended for ensuring the long life of bearings and crankshafts.
