Crankshaft Grinding And Repair of High Capacity Engine

It is generally observed that high-capacity diesel engine crankshafts have lengths ranging from 6 meters to 12 meters and weigh up to 20 tons. Again, the diameter of the crankpin and main journal varies between 500 mm to 700 mm and in some cases more than 700 mm.

In case of the following problems during the operation of the engine, crankshaft grinding and repair are recommended.

The crankshaft repair is also recommended after the engine has completed the designated number of operation hours.

Reason for crankshaft repair and crankshaft grinding:-

Irrespective of the application of diesel engines for marine or land-based operations, in most cases, the engines are operated continuously, which results in various deviations in the crankshaft.
The measurements of various parameters including taper and ovality need to be checked periodically or at the time of overhauling and are to be maintained within the stipulated tolerances.
The parallelism, linearity, and run-out have to be within limits.
The surface finish of the crankpin and main journal have to be within The surface finish of the crankpin and the main journal have to be within the standards.
The radius fillet and lubricating oil hole should be according to the original profile and dimensions as per the drawing of the crankshaft.

Above are some of the reasons that require crankshaft grinding and crankshaft repair.

RA Power Solutions Pvt. Ltd. with experience of more than four decades undertakes crankshaft grinding and crankshaft repair up to the diameter of 700 mm on-site and without removal of the crankshaft from the engine block. The length and the weight of the crankshaft are not a criterion for us for Crankshaft grinding or Crankshaft repair.

The following parameters are maintained at the time of crankshaft grinding and crankshaft repair.

The Taper and ovality of the crankpin and main journal are strictly maintained as per the tolerances stipulated in the manufacturer’s manual.
After grinding and repair are undertaken by RA Power Solutions, all the parameters like surface finish, the profile of radius fillet, lubricating oil hole, and parallelism are maintained and checked as per the original specifications.
The crankshaft is inspected by experienced technicians for all the parameters and inspection reports are prepared and shared with the clients.

onsite crankshaft repair — **Crankshaft repair**

RA Power Solutions gives great importance at the time of crankshaft grinding and crankshaft repair not only to the maintenance of taper and ovality but to the surface finish of the crankpin and main journal which is maintained within an RA value of 0.3 um.

We have experienced that the maintenance of the high surface finish of the crankpin and main journal after grinding reduces the friction between the bearing and the crankpin and enhances the life of the crankshaft. It is our experience that bearing life is also increased manifolds.

We specialize in expert crankshaft grinding and repair and marine crankshaft repair services. The crankshaft is a critical component of any engine, and its precision and smooth operation are vital for optimal performance.

With cutting-edge technology and skilled technicians, RA Power Solutions offers top-notch crankshaft grinding and repair services and marine crankshaft repair to ensure the highest level of accuracy and reliability.

Crankpin Grinding by Crankshaft Grinding Machine – RA Power Solutions

A diesel power plant based in northern India having 10 nos. of 12.3 MW Wartsila diesel generating sets reported severe causality involving one of their Wartsila generators.

RA Power Solutions team of technicians rushed to the power plant with the measuring instruments and onsite crankshaft grinding equipment to assess the cause of the breakdown.

Wartsila Diesel Generating Sets Installed in Plant

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

The following were the main observations:

Taper and ovality in the crankpin were observed as 0.70 mm.
Due to the failure of the bearing, deep line marks were visible.
Hardness and MPI tests were done, and no cracks were observed.

RA Power Solutions used the latest design of onsite crankshaft grinding machine having almost no vibrations. The crankpin was undersized by 1.5 mm maintaining the tolerance within 10 microns. Our technicians took only 18 hours to complete the Crankshaft repair from the time of the start of the preliminary inspection, grinding, and final inspection. The repair of the crankpin in such a short time was possible due to the latest technology onsite crankshaft grinding machine used and the experience of our technicians. The engine was assembled and is performing satisfactorily.
