Diesel Engine Overhaul | Onsite Diesel Engine Repair | Crankshaft Main Bearing Replacement

RA Power Solutions was informed regarding the failure of three nos Crank pin Bearings of MAN B&W 5L60MC main engine onboard a vessel near South Africa.

RA Power experienced team of technicians boarded the vessel in a short time of 18 hours of receipt of intimation regarding the problem faced by the vessel. Following jobs were executed for overhaul and replacement of crankpin bearings in order to operate the engine satisfactorily after Engine repair and engine overhaul.

DESCRIPTION:

Inspection and overhaul of the cylinder covers, including the fuel and starting valves located in the covers.
The cylinder covers cooling spaces were also inspected, cleaned, and fitted back with new O-rings.
Dismounting, Inspect and overhaul the exhaust valves, renewing the seats, and grinding the valve spindles.
The cylinder liners were cleaned, calibrated, and honed in order to restore the liners running surfaces and remove ovality. This ensured that the piston rings perform better and this will lead to a better overall cylinder condition, compared to if honing had not been done. The cylinder liners cooling spaces were also inspected, cleaned, and fitted back with new o-rings.

Inspection of Engine Spares is in Process

The Crank pin bearing caps were dismounted, and both top and bottom bearing shells renewed.
The Crankshaft Crankpin diameter was checked for the following parameters:
- Visual inspection to check the presence of any Bearing Line marks or rough surface.
- All the Crankpins were calibrated for taper & ovality.
- Hardness was checked and observed within limits.
- MPI was done to check the presence of any crack.
- Crankshaft all pins were polished by an onsite crankshaft grinding machine, removing the bearing line marks and improving the Crank pin surface finish.
- Adjustment of the variable injection timing (VIT).
- The bearing clearances were taken using lead wire.
- Crankshaft alignment measurement was taken with a dial gauge.

Conclusion:

After the replacement of Bearings and jobs described above undertaken at the time of engine overhaul and bearing replacement the engine was tested on the load & performance was observed to be satisfactory.

Engine Block Repair | Onsite Machining | Crack Repair

Serving the diesel power plants and shipping companies for the last four decades, we observed that in spite of the best maintenance protocols and process followed, accidents do take place. We have the history of repairing seriously damaged engine blocks.

Recently in case of Wartsila Engine Both sides of the engine block got damaged measuring about 600 mm * 500 mm . Even the main journal housings got damaged due to accident. The engine was installed on a barge having 6 units of wartsila 12V32 engines.

Following job was done pertaining to engine block repair:-

The complete engine block was subjected to crack detection by MPI test by level 3 qualified technicians.
Main journal housings of engine block were dimensionally checked for taper and ovality was recorded.
The damage to engine block was so serious that we have no option but to cut off the damaged portion of the engine block.
The new casting piece was manufactured with the similar profile of damaged block of wartsila 12V32 and was given original profile by onsite machining. The piece was assembled by metal stitching and metal locking process.
All the main journal housings were corrected by onsite machining, maintaining the main journal housing bore size strictly as per the engine manufacturer’s limits.

The above engine block repair saved client considerable amount and reduced downtime.
