We recently completed a successful onsite repair of a BERGEN B32:40L8P engine crankshaft onboard a vessel in Jamaica.

The details of the job are as follows:

Onsite Inspection of Crankshaft – BERGEN B32:40L8P

• Two of our experienced technicians, along with our portable onsite crankshaft grinding equipment, traveled from New Delhi, India, to Jamaica.
• Our equipment is lightweight, compact, and portable, allowing it to be transported as accompanied baggage, which eliminates delays associated with cargo shipment and customs clearance.
• Upon boarding, the vessel was found fully loaded with containers, yet our team immediately initiated the crankshaft inspection.
• It was observed that Crankpin No. 5 had suffered severe damage due to a bearing failure.
• The crankpin was thoroughly cleaned, and embedded bearing material was carefully removed.
• Dimensional checks revealed:
  • Minimum Diameter: 269.75 mm
  • Maximum Diameter: 270.00 mm
  • Ovality: 0.25 mm
  • Deep scoring marks were also noted due to the bearing failure.
• A Magnetic Particle Inspection (MPI) using a high-intensity Magnaflux torch was conducted to check for cracks. No cracks or abnormalities were detected.
• Hardness testing was performed, and confirmed that values remained within permissible limits.

Onsite Grinding of BERGEN Crankpin

• The crankpin was calibrated and ground in multiple stages, with ovality strictly controlled during the process.
• Due to deep scoring, the crankpin had to be ground to an undersize of 2 mm.
• The final dimension achieved was 268.00 mm – 0.02 mm, ensuring precision and compliance with engine requirements.

Engine Commissioning

• The vessel had a 2 mm undersize bearing in stock, which was installed immediately after grinding.
• A trial run of the engine was conducted in the presence of our technicians, and performance was found to be fully satisfactory.

On site crankshaft polishing and crankshaft grinding machines have the following advantages:

• In case of the development of line marks, pitting, watermarks, etc. it is advisable to undertake the polishing.
• The introduction of the crankshaft polishing machine by RA Power Solutions has made it very easy and simple to polish the crankpin and main journal.
• The polishing enhances the surface finish, removes line marks, and pitting marks, and makes the crankpin and main journal diameter as smooth as the original.
• It is a known fact that in case the crank pin and main journal diameter have line marks and poor surface finish the bearing life is reduced. There is also a chance of serious damage to the crankpin and main journal of the crankshaft and corresponding bearings. To increase the life of the crankshaft of a diesel engine, compressor, rotor, or alternator it is advisable to undertake the polishing periodically.
• The cost of a machine manufactured by RA Power Solutions is very low and can be owned by shipping companies, heavy engineering plants, repair workshops, etc.
• The machine is lightweight, portable, and can be taken to the site all over the world.
• With the polishing machine, you can also undertake the grinding of crankpins and main journals.

RA Power Solutions manufactures crankshaft polishing machines and onsite crankshaft grinding machines up to 700 mm in diameter and has sold more than 70 machines all over the world for the last 43 years.
