Why On-Site Crankshaft Repair is Recommended

• Irrespective of whether diesel engines operate in marine or land-based applications, they run continuously in most cases, which results in various deviations in the crankshaft.
• Technicians need to check the measurements of various parameters, including taper and ovality, periodically or during overhauling and maintain them 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 RA Power Solutions undertakes grinding and repair, the team maintains and checks all parameters, such as surface finish, radius fillet profile, lubricating oil holes, and parallelism, according to the original specifications.
• Experienced technicians inspect the crankshaft for all parameters and prepare inspection reports, which they share with the clients.
