With the introduction of new, revolutionary technology, the compressor crankshaft can be inspected on-site and repaired if required.

RA Power Solutions provides crankshaft repairs for ammonia and refrigeration compressors, ensuring quick restoration without disassembly.

The following are the common problems observed in compressor crankshafts :

  • Excessive wear and tear of crank pin and main journal.
  • Increase of oil gap between the crank pin, main journal, and bearing.
  • Frequent damage to crank pin and main journal bearings due to the development of excessive taper and ovality.
  • Seizure of crank pin and main journal bearings on compressor crankshaft due to non-replacement of bearings within the specified schedule.
  • Development of rough surface of crankpin and main journal due to bad quality of lubricating oil and lubricating oil filters.
  • Damage to both sides of the radius fillet due to an accident.
  • Damage to crank pin of compressor crankshaft due to excessive ovality in connecting rod big end bore.

With the introduction of the latest technology, there is no requirement to dismantle the crankshaft from the compressor casing.

Our technicians visit the site and undertake on site compressor crankshaft inspection. We have on-site compressor crankshaft polishing and grinding equipment available which is carried by our technicians and repairs are undertaken in no time.

SAVE YOUR COMPRESSOR CRANKSHAFT AND INCREASE THE LIFE:-

 Save crankshaft repairs for ammonia and refrigeration compressors.We strongly suggest for medium and high-capacity compressors that their crankshafts should be periodically calibrated for taper and ovality, rough surface, hardness, and crack detection.

It is always advisable to get the crankshaft compressor inspected so that corrective action can be taken on time.

The loss of the crankshaft brings the whole plant to a stand-still and now can be avoided by availing the expert services of RA Power Solutions, we regularly undertake inspection and repair of compressor crankshaft of Ariel, Cummins, Kirloskar, Samson, Porter-Cable, Stanley Bostitch, Campbell Hausfeld, DeWalt, Makita, Senco, ANEST IWATA, Gardner Denver, Graham Sulzer, Hitachi, Rolair Systems, Brehob, Lufkin, Zebra, Ingersoll Rand, etc.

Crankpin Machining | Crankshaft Journal Machining | Crankshaft Grinding Services – RA Power Solutions

RA Power Solutions is based in New Delhi, India, undertaking crankshaft machining for the last 44 years. Crankshafts are repaired on site without removing them from the crankcase. In case of any damage to the crankshaft, crankpin, and leading journal we can machine it and polish it to a standard undersize within the manufacturer’s specification and tolerances specified.

The main advantage of the repair of the damaged crankshaft, and crankpin journal on site is that it requires a very short repair timescale. It works out to be cheaper to get the onsite crankshaft machined and polished as there is no need of removing the crankshaft from the block, packing and sending it to the designated workshop. At the same time, all the specifications and tolerances as per the engine manufacturer are maintained.

Crankshaft Reconditioning | Crankshaft Grinding Machine Exporter – RA Power Solutions

RA Power Solutions undertakes the repair of crankshafts having a diameter ranging from 35 mm to 700 mm. The concept of removing the crankshaft and sending it to the workshop for repair is now no longer valid, and the user gets the crankshaft repaired onsite.

During our working of more than forty years on marine main, crankshaft reconditioning, auxiliary engines, and high capacity diesel generating sets installed in industry, power plants, etc., we have observed that while the maintenance schedule stipulated by the engine manufacturer in the maintenance manual is religiously followed, but no attention is paid on the crankshaft’s condition.

Even during the maintenance schedule of 25,000 to 30,000 hours of operation, maintenance agencies and officials connected with the day-to-day upkeep of the engine ignore the inspection of the crankshaft till the seizure of bearing or any other major breakdown happens in the crankshaft.

We have experienced that irrespective of the metallurgy of the crankshaft and level of hardness after continuous operation of engine taper and ovality of the crankshaft, crankpin, and main journal are developed. The bearing surface becomes rough and in some cases bearing line marks, pitting, etc. is developed. Due to these abnormalities developed in the crankshaft, failure of bearing and crankshaft takes place. RA Power Solutions recommends that inspection procedures should be followed in order to ensure satisfactory performance of the crankshaft and to save it from rejection.

  • During the periodic maintenance schedule, the crankpins and main journals of the crankshaft should be checked for the development of taper and ovality.
  • The dimensions of the crankpin, taper, and ovality should be well within the limits specified by the manufacturers. There should not be any presence of bearing line marks or pitting on the crankpin journals.
  • The profile of the lubricating oil hole and radius fillet should be checked visually. There should not be any loss of the original profile.
  • The hardness test and the crack detection test by MPI or dye penetrant are not required till the major failure of the bearing or accident takes place.

  • Checking of deflection of the crankshaft.
  • Positioning of crankshaft balancing weights. They should be tightened on specific torque as per the manual.

In case the above preventive inspection is undertaken on-site without disassembly of the crankshaft, the user can avoid any major damage to the crankshaft.

Onsite Machining of crankpins and main journals has been made simple in this era of technological renovation. The concept of removing the crankshaft and getting the crankshaft machined in the workshop is no longer valid. The onsite crankshaft machining is undertaken to maintain strictly all the tolerances as specified by the manufacturer and stipulated in the maintenance manual.

Crankshaft machining is no longer the monopoly of a bunch of companies based in Europe and the UK. The availability of a portable, easy-to-operate crankshaft grinding machine it has made simple and easy to undertake the polishing and grinding of the main journal if required.

RA Power Solutions is a reputable and leading crankshaft grinding machine exporter and crankshaft reconditioning, known for its high-quality products and exceptional services. With a strong commitment to customer satisfaction, RA Power Solutions has gained a stellar reputation in the industry. Our state-of-the-art crankshaft grinding machines are designed to precision grind and polish crankshafts, ensuring optimal performance and longevity of engines.

The failure of the crankpin and main journal bearing causes serious damage to the crankshaft, which is as follows:

  1. Development of excessive taper and ovality in Crankshaft, Crankpin, and Main Journal.
  2. Development of crack
  3. Abnormal increase and decrease in hardness
  4. Loss of alignment of crankshaft, resulting in the increase in deflection readings.
  5. Development of bearing line marks, pitting, local depression
