Consequences of Hand Polishing of Crankshaft & Benefits of Onsite Polishing Machine- RA Power Solutions

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 have been working on crankshafts of marine engines and engines used for various applications with the diameter ranging from 30 mm to 700 mm.

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

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

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

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

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

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

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 of the cases hand polishing rather deteriorates the condition of crank pin and main journal and in some cases results in the rejection of crankshaft.

Recently one of our client having 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 the rough surface was 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. Few photographs are given below:

The Stitching Process
1. At first visible and invisible cracks are identified.
2. The parts are clamped together to bring the parts in original position.
3. A rectangular hole is made across the fractured portion.
4. This hole is made by drilling and chipping.
5. The Master lock, large rectangular key of special metal is inserted into the hole.
6. Locking Pins are inserted alongside the master lock to provide a tight and secured master lock.
7. A length of metal stitching keys are inserted on the sides of the master lock to prevent the locking pins to fall out when the casting is subjected to high vibrations.

Advantage of Metal Stitching
1. No heat stress are induced
2. No Distortion occurs
3. In many Instances machining is not required
4. Invaluable in emergency situations
5. Reduces downtime
6. Gas/ Liquid proof repair

On undertaking the detailed inspection of crankshaft including dimensional check, hardness test, MPI for crack and deflection, it was observed that one of the crankpin journal was damaged due to the failure of big end bearing.

Following were the main observations:

I) Taper and ovality in crankpin was observed as 0.70 mm.

II) Due to failure of bearing, deep line marks were visible.

III) Hardness and MPI test was done, no cracks were observed.
