Manufacturers of high capacity diesel engines are maintaining close tolerances in terms of taper and ovality of crankpin and main journal diameter of the crankshaft. The maintenance of close tolerances and high surface finish results in the generation of more power, longer life of crankshaft and bearing, less noise level, low vibration, friction, and better fuel efficiency. RA Power Solutions has been working on crankshafts of marine engines and engines used for various applications with diameters ranging from 30 mm to 700 mm.

In general, the following close tolerance of the crankpin and main journal are observed:

I) The Taper and ovality of the crankpin and the main journal are maintained between 0.02 mm to 0.05 mm depending on the diameter of the crankpin and main journal.

II) The surface finish of less than 0.25 RA value is maintained.

RA Power Solutions has observed that sometimes due to an emergency, to put back the engine into operation, the crankshaft crankpin and main journal are hand polished with emery paper, nylon rope, and other means. This has serious consequences for the CR pin and the main journal. A few of them are as follows:

I) Bearing line marks, and pitting marks are observed on the crankpin and the main journal of the crankshaft cannot be removed by hand polishing.

II) It is our experience that in the case of the development of taper and ovality, it can never be reduced and controlled by hand polishing. On the contrary ovality and taper increase.

III) The surface finish of the crankpin and main journal is of great importance.

IV) It is observed that by hand polishing the marks can never be removed fully. Thus the desired surface finish as per the manual cannot be maintained.

RA Power Solutions, during their work on high-capacity engines installed with clients, spread all over the world, have observed that in most cases hand polishing rather deteriorates the condition of the crankpin and main journal and in some cases results in the rejection of the crankshaft.

Recently one of our clients has 3 generators of MAN B&W 8L 23/30 had a problem in all crankpins having a standard diameter of 185mm. Bearing line marks and a rough surface were observed. All the crankpins were hand-polished by nylon wire and new bearings were used. The crankshaft failed within 20 minutes of the operation of the engines. A few photographs are given below:
