Crankshaft Reconditioning | Crankpin Reconditioning and Machining | Onsite Crankshaft Grinding & Polishing – RA Power Solutions

RA Power Solutions is a pioneering name in the realm of on site machining services. With a commitment to precision and excellence, they offer a comprehensive suite of solutions aimed at addressing complex machining challenges without the need for equipment dismantling.

RA Power Solutions undertakes complete reconditioning of crankshaft of marine engines, Diesel generating sets, Compressors, forging hammers, and all other applications. The crankshaft repair is undertaken onsite without removing the crankshaft from the crank casing. This saves the downtime of the equipment and cost of assembly of the engine after the crankshaft repairs are executed, in fact companies are opting for on site repair of crankshaft and sending the crankshaft to the workshop for repair is outdated.

The following procedure is adopted by our experienced engineers for calibration:

Prior to starting of the repair of crankshaft, crank pin, and main journals are subject to the following inspection:

  1. Crankpin and main journal are measured for the presence of taper and ovality.
  2. The alignment of crankshaft is checked by deflection.
  3. Radius fillet and lubricating oil hole are inspected for their original profile.
  4. Inspection of hardness
  5. Crack detection by MPI/Ultrasound and dye penetrant test.
  6. Checking of surface finish
  7. Visual inspection of counterweight and counterweight bolts. In case of accident, crack detection by MPI is recommended.

Based on the above observations, the crankshaft is repaired onsite maintaining the following parameters:

  1. The grinding of crankpin and the main journal is undertaken as per the undersize recommended by the manufacturers and the availability of the bearings with the engine manufacturers.
  2. Preparation of radius fillet, lubricating oil hole, and maintenance of profile as the original.
  3. Polishing of crank pin and main journal, maintaining the surface finish as per international standards.
  4. Checking of hardness and crack detection test after repairs are executed.

We have a team of experienced technicians and the necessary instrumentation to undertake the repair of the crankshaft on board a vessel, even while sailing or for stationary engines.

Engine population is rapidly increasing for the shipping industry, power plants and various applications. In most of the cases engines are used not only for the emergency purpose but as a base load. The continuous running of diesel engine results to wear and tear of the crankpin and main journal of the crankshaft. In certain cases taper and ovality more than the permissible limit is developed in the crankpin and the crankshaft main journal.
