The vessel was not able to cross the Suez Canal due to the non-operation of two numbers of auxiliary engines. The third auxiliary engine was also not in good condition and was able to take the load of only 50%. RA Power Solutions deputed two technicians to Suez Egypt and boarded the vessel.

Following are the details of the Engine & Crankshaft

Observations & actions taken by RA Power Solutions to repair successfully the crankshaft of Daihatsu 5DC-17 as follows

• The five-number crankpins of AE#01 and AE#03 were checked dimensionally. The taper & ovality of 0.20 mm to 0.30 mm has observed in AE#01 and in the case of AE#03, the ovality was more than 0.50 mm. Other parameters like hardness, MPI test, deflection, and visual inspection of damaged crankpins were undertaken & observed within limits.
• The grinding of all five crankpins of AE#01 was undertaken to the undersize of 0.5 mm and AE#03 was undersized by 1.0mm.
• All parameters were again checked after grinding was executed and observed satisfactory.

Supply Of Undersize Bearing Of Daihatsu 5DC-17 as follows

The crankpin repair undersize bearing of Daihatsu 5DC-17 of 0.5 mm and 1.0 mm was supplied by RA Power Solutions. The engine was commissioned successfully.

Only a company in the world can undertake repair of the crankshaft of a Daihatsu engine with a damaged radius fillet while sailing of the vessel.

• The Bearing width of Daihatsu 5DC-17 is only 64 mm. It requires a very compact onsite crankshaft grinding machine to execute the repair which no other company in the world possesses.
• RA Power Solutions is the only organization that has successfully executed the repair of the crankshaft of Daihatsu 5DC-17 has more than a hundred numbers successfully and saved millions of dollars for the ship owners.

We have observed that due to an accident, the radius fillet of the crankpin and main journal gets damaged or worn out, In which condition it becomes difficult to undertake the grinding of the crankshaft as most companies have the grinding tool which is placed on the radius fillet and undertakes the grinding by taking the reference of fillet radius.

In this situation, the crankshaft repair companies either reject the crankshaft or recommend sending the crankshaft to a designated workshop for repair. We are the only company in the world that can undertake the grinding of crankpins having damaged radius fillets. We have the credit and experience of successfully undertaking the repair of crankshaft radius fillets which is damaged or worn out.

Successful Repair of damaged Fillet radius Crankshaft

• It is generally noticed that in case of seizure of bearing the bearing material gets embedded on the crankpin and the radius fillet of both sides.
• The radius fillet gets damaged either during the failure of the bearing as the bearing steel shell rubs with the radius fillet or the bearing material gets embedded on the radius fillet which while removing damages the radius fillet.
• Crankshaft repair companies take the reference of radius fillets for grinding purposes and are not able to undertake repair due to damaged radius fillets.
• RA Power Solutions has the necessary tools, equipment, and expertise for the repair of a crankshaft having a damaged radius fillet.
• Don’t reject or send it to the workshop contact RA Power Power Solutions who will undertake the repair of the damaged radius fillet crankshaft onsite whether on the vessel or for land base engines.
• Our technology and equipment are so advanced that the damaged radius fillet crankshaft repair is possible even while the vessel is sailing in a disturbed condition.

We have successfully executed damage radius crankshaft repair of MAN B&W, Yanmar, Daihatsu, Wartsila, Ruston & Hornsby Engine, etc.

We have been regularly executing the on-site crankshaft and Engine repairs in Chennai Port Tamil Nadu, Cochin Port Kerala, Ennore Port Tamil Nadu, Jawaharlal Nehru Port Maharashtra, Kandla Port Gujarat, Kolkata Port West Bengal, Krishnapatnam Port Andhra Pradesh, Mormugao Port Goa, New Mangalore port Karnataka, Paradip port Odisha, Tuticorin port Tamil Nadu, Visakhapatnam port Andhra Pradesh, etc.

Crankshaft Failure

• Use of nonstandard lubricating oil or using it for an extended time without changing it.
• Use of bearings beyond the operating hours specified in the maintenance manual of the engine manufacturer.
• Use of substandard lubricating oil filters and using them beyond the specified hours.
• Not maintaining the lubricating oil temperature and oil gap as per the maintenance manual.
• Use of substandard quality bearings.
• Not carrying out the periodical inspection of the crankshaft at the time of undertaking maintenance.
• Non-calibration of crankpin and main journal diameter for taper and ovality.
• Ignoring of crankpin and main journal line marks, pitting, rough surface.
• Increase in deflection readings.
• Non-replacement of connecting rods in case of abnormalities observed.
• Non-calibration of connecting rods big end bore and small end bore.
• Non-inspection of connecting rods, bolts for cracks or distortion, and tightening torque.

As mentioned the crankshaft failure can be caused due to not paying attention to the above.

RA Power Solutions Pvt. Ltd. has been working on the crankshaft of medium and high-capacity engines, 2-stroke and 4-stroke engines for four decades and strongly suggests that all the parameters mentioned in the maintenance manual of the engine manufacturer should be checked.
