Repair of MAN Engine Model no. 9L28/32 Diesel Generating set Crankshaft

RA Power Solutions deputed two technicians along with an onsite crankshaft grinding machine and technicians boarded the vessel at port of Jebel Ali Dubai. On conducting the inspection following are the main observations of the crankshaft of MAN Engine Model no. 9L28/32 diesel Generating sets.

It was observed that the crankpin no. 3 of the AE#02 was damaged. The Bearing material was embedded on the crank pin diameter. After removal of the white metal from the crankpin, the dimension inspection was done and the following was observed:
- Minimum crankpin diameter observed: 229.44 mm
- Maximum crankpin diameter observed: 229.83 mm
The above readings were observed against the standard diameter of 230.00 mm.
The radius fillet and lubricating oil hole profiles were found acceptable with no damage.
Deep Bearings line marks were observed on the remaining 8 numbers of crankpins.
All the crankpins were subject to hardness test and crack check by MPI method and no abnormality was observed.
All other parameters were observed within limits.

Successful Crankshaft Repair of MAN Engine Model no. 9L28/32

The grinding of crankpin no. 3 was initially undertaken to the undersize of 1.0 mm maintaining the crankpin diameter of 229.00 mm. Since the Bearing line marks were still visible it was decided to grind further. The final size maintained after grinding and polishing was 228.50 mm which is 1.5 mm undersize.
Considering the rough surface finish and bearing line marks all the remaining crankpins were polished while using the state of art crankshaft grinding & polishing machine using the latest polishing media.
The surface finish of less than 0.20 RA value was maintained.
The ship had the 1.5 mm undersize bearing available which was assembled and the engine was put on load.

RA Power Solutions having more than 41 years of experience in extending crankshaft grinding, metal stitching, rebabbitting of bearing, and all the services related to engine repair. We undertake onsite grinding of crankshaft up to 700 mm diameter.

Repair of MAN B&W Model 5L 16-24 by Using Onsite Crankshaft Grinding Machine

MAN Engine Model no. 5L 16/24 is a very common installation on vessels and the engine is used as Generator. The Crank Pin diameter of MAN Engine Model no. 5L 16/24 is only 130mm and the bearing width is 56 mm. In other words, it is about 2 inches

This makes the onsite crankshaft repair very difficult due to limited space in between the two webs. Most onsite crankshaft repair companies based in Europe don’t have the equipment and the technology to undertake grinding/ repair of crankpin of MAN Engine Model no 5L 16/24. The repair companies always suggest to remove it from the engine block and send it to workshop for crank pin grinding or reject the crankshaft.

We successfully executed the repair of the crankshaft of MAN Engine Model no. 5L 16/24. Details are as mentioned below:

S. NO	Crankshaft Details
1	Engine Make	MAN B&W
2	Engine Model	5L 16/24
3	Crank pin Diameter Standard	130 mm
4	Crankpin Bearing Width	56 mm
5	Place of execution of crankshaft repair	Port of Castellon Spain

Details of Crankshaft repair job executed by RA Power Solutions technicians at a port of Castellon Spain.

The damaged crankpin was checked for taper & ovality and it was observed 0.49 mm.
Deep bearing line marks were observed.
All other parameters like hardness and crack detection by MPI were checked and no abnormality was found.
The crankpin was ground to an undersize of 1.0mm.

Supply of Undersize Bearing for MAN Engine Model No. 5L 16/24

It is obvious that whenever grinding is undertaken there is requirement of undersize bearing. In this case of MAN Engine Model no. 5L 16/24, RA Power Solutions arranged and supplied 1.0 mm undersize crankpin bearing to the client.

We maintain a large stock of standard & undersize bearings of crankpin & main journal of popular make & model of engines like Yanmar, Daihatsu, MAK and MAN B&W, etc.

Insitu Crankshaft Machining And Repair Of Yanmar Engine

Yanmar Diesel Generator Model no 8N280L-EV

RA Power Solutions was approached by one of the largest shipping companies based in Athens Greece regarding the breakdown of the Crankshaft of YANMAR Diesel Generator Model no. 8N280L-EV. The vessel was to take a berth at Mundra port India and the stay of the vessel at the port was limited to only 13 hrs.

Action taken by RA Power Solutions for successful repair of Crankshaft of Yanmar Diesel Generator Model no. 8N280L-EV.

As mentioned above we were given only 13 hrs of time at Mundra Port India to inspect the crankshaft and execute the repair. In this situation, we decided to depute a team of three technicians onboard the vessel instead of two technicians which is our normal practice.
After boarding the vessel and Insitu Crankshaft Machining, a detailed inspection of crankpin no. 4 which got damaged was conducted.

Following are the main observation:

The diameter of crankpin no 4 was checked and the following dimensions were observed:
- Minimum diameter observed – 224.15 mm
- Maximum diameter observed – 225.00 mm

The above shows the ovality of 0.85 mm.

The deep scoring marks on crankpin were observed as bearing got seized.
The crankpin no. 4 was subject to hardness check and was found within limits except on few scattered points where it was observed in the range of 500 HB.
The crankpin was subject to crack detection by high intensity magnaflux torch and no cracks or abnormally was observed.
Due to the seizure of the crankpin bearing the radius fillet of both the sides was badly damaged.

Successful Repair of Crankshaft of Yanmar Diesel Generator Model no. 8N280L-EV in a short time of 13 hrs undertaken by RAP Engineers

Our technicians worked non stop and were able to successfully repair the crankpin no. 4 by under sizing and grinding it to 1.0 mm.
After grinding & polishing following minimum & maximum crank pin diameter was maintained:
- Minimum diameter observed – 223.98 mm
- Maximum diameter observed – 224.00 mm
The above reading shows the crankpin was undersized by 1.0 mm from 225.00 mm to 224.00 mm thus maintaining the ovality of only 0.02 mm which is far superior than the tolerance stipulated in the manufacturer’s manual.
The formation of radius fillet at both ends was a big challenge as it was badly damaged and time available was limited. The radius fillet was also repaired successfully.
The 1.0 m undersize crank pin bearing was available onboard the vessel.
RA Power Solutions technicians also helped the ship technical staff in calibration of connecting rod, measurement of big end bearing, and other areas.
It is normal for RA Power Solutions to take such challenging jobs where the damage to the crankshaft due to an accident is very serious and the time available is short.
We have a team of technicians who are experienced to take on such challenging assignments. The availability of most modern onsite crankshaft grinding machine with RA Power Solutions also helps us to expedite the job and finish it in the minimum possible time.
- We use high capacity, lightweight, and compact Pneumatic Turbine to execute the repairs
