In Situ Crankshaft Grinding in Singapore

RA Power Solutions is a global leader in insitu crankshaft grinding and repair services, with a strong presence at Singapore Port. Known as one of the busiest maritime hubs in the world, Singapore demands fast, reliable, and professional marine repair solutions. RA Power Solutions provides onsite crankshaft grinding in Singapore, ensuring minimal downtime and maximum efficiency for vessels and industries operating in this vital region.

Why Engines Need In Situ Crankshaft Grinding?

Over time, crankshafts face wear and tear due to:

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.

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 The concept of removing the crankshaft and sending it to the workshop for repair is now no longer valid, and the user gets the crankshaft repaired onsite.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.

RA Power Solutions is a reputable and leading crankshaft grinding machine exporter and crankshaft reconditioner, known for its high-quality products and exceptional services.

Crankshaft Grinding Executed on Board a Vessel – RA Power Solutions

RA Power Solutions has executed successfully the crankshaft grinding of 6 pins on board a vessel at Dumai/Lubuk Gaung Port, Indonesia of MAN B&W STX 6L23/30H Engine.

In this case, crankshaft grinding was required because all the CR pins, having a standard diameter of 185 mm, developed taper and ovality. Out of 6 CR pins, not even a single pin was seized, nor was a crack developed.

**Crankshaft Deflection and MPI Test Under Process**

The above observations show that the engine users should periodically get the crankshaft calibrated and go for grinding and polishing as the crankshaft develops taper and ovality due to continuous running.

To execute the above job, RA Power Solutions Pvt. Ltd. used a lightweight crankshaft grinder, which is lightweight, and the crankshaft grinder was taken to the site. RA Power Solutions has sold more than 60 crankshaft grinding machines all over the world.
