I) On investigation of Wartsila diesel generating sets, it was observed that it was clear case of lube oil pump failure.

II) All 6 crankpins were found damaged.

III) Inspection in detail was carried out. Gist of which is as following:

a) Crankpin no. 1 ovality of 0.76 mm. No cracks observed. Hardness within limits.

b) Crankpin no. 2 ovality of 0.54 mm. No cracks observed. Hardness within limits.

c) Crankpin no. 3 ovality of 0.26 mm. No cracks observed. Hardness within limits.

d) Crankpin no. 4 ovality of 0.49 mm. No cracks observed. Hardness within limits.

e) Crankpin no. 5 ovality of 0.29 mm. No cracks observed. Hardness within limits.

f) Crankpin no. 6 ovality of 0.62 mm. No cracks observed. Hardness within limits.

After initial inspection of crankshaft, it was decided to undertake the repair of crankshaft of Wartsila 6R32 by grinding the crankpin.

Three nos. of pins were ground undersize by 1mm and balance 3 were undersized by 0.5 mm. The taper, ovality and surface finish has been maintained far better than manufacturer’s recommendations.

The above job was executed in record time of 6 days.

RA Power Solutions Pvt. Ltd. manufactures white metal Babbitt bearing having diameter up to 1500 mm. The outer steel casing material is selected according to the application. The grade of white metal is again determined by the design parameters. The Babbitt white metal is imported by us from a leading manufacturing company based in Spain. The babbitting of white metal on the steel casing is done by centrifugal system which ensures that babbitt white metal is bonded strongly with the casing. The white metal babbitting by centrifugal system is proved and widely used in the industry. The thickness of white metal is maintained as per the requirement.

RA Power Solutions Pvt. Ltd. has in house facilities to carry out various machining operation after white metal babbitting is done. The bore size is maintained within the tolerances as per the manufacturer’s requirement.

The rebabbitting of old bearings is also undertaken. The old Babbitt white metal is removed and steel casing is subject to inspection for presence of any crack, higher hardness, deformation of profile, etc. In case all the parameters required are within limits of the steel casing the rebabbitting of white metal is undertaken using the same grade of white metal or superior grade of babbitt white metal in order to ensure far better performance after rebabbitting of old white metal is done

We export new Babbitt bearings and also undertake rebabbitting of old bearings for the reputed companies based all over the world.

We are quality conscious and are very competitively priced with minimum delivery period.
