In Situ Crankshaft Grinding And Repair: Advanced Onsite Solutions by R A Power

In fields including maritime, power generation, oil and gas, and heavy industry, where engine performance affects productivity, a crankshaft failure might stop work completely. When that happens, time equals money, and typical repair procedures are no longer efficient.

This is when in situ crankshaft grinding is the better option.

We at R A Power Solutions are experts in In Situ Crankshaft Repair and Insitu Crankshaft Machining. We can do it quickly, reliably, and to OEM standards, no matter where you are in the world.

What is meant by “in situ” crankshaft grinding?

In Situ Crankshaft Grinding is a new method that lets you grind and polish broken crankpins and main journals right where they are, without taking the crankshaft out of the engine casing. This cuts down on the time, money, and hassle of taking apart and moving heavy parts.

Why Should You Choose In Situ Crankshaft Repair?

Crankshafts can be damaged by bearings that fail, overheating, being out of alignment, and not having enough lubricating oil. If these problems aren’t fixed right away, they can cause the engine to fail completely.

Insitu crankshaft repair can fix these problems before they get worse. At R A Power Solutions, we offer the following services:

  • Machining the crankshaft in place to fix the surface shape
  • Grinding crankpins in place to exact OEM specifications
  • In-place crankshaft grinding repair for scoring, ovality, and taper
  • Polishing and reconditioning on site to make the crankshaft last longer

Onsite Crankshaft Grinding & Polishing By Revolutionary Portable Equipment – RA Power Solutions

Crankshaft journal and crankshaft crank pin diameter should be ground and polished to attain a surface finish of 15 microinches or better. Again, the maintenance of the taper and ovality of the crankpin and crankshaft main journal has to be within the limit recommended by the manufacturer. Generally, the limits are within 0.02 to 0.05 mm, depending on the diameter of the crankpin and main journal. A few years back, it was a monopoly of a few European companies undertaking onsite crankshaft grinding and crankshaft polishing jobs, charging exorbitant prices from the shipping companies and the power plants, who had no option but to get the job of onsite crankshaft grinding and crankshaft polishing done from them.

Crankshaft Repair does not require the crankshaft to be removed from the entablature. In the recent past, due to seizure of bearings or development of taper, ovality, or loss of alignment of the crankshaft, it was necessary to remove the crankshaft from the engine block and send it to the designated workshop for crankshaft grinding and crankshaft repair.

The introduction of lightweight, vibration-free crankshaft grinding equipment facilitates grinding of the crankshaft, crankpin, and crank main journal on the spot while the crankshaft is assembled in the engine block. There is no necessity for even the decoupling of an alternator and other accessories from the diesel engine. The portable crankshaft grinding machine is placed on the crankpin or crank main journal through the inspection window of the entablature, and the grinding and polishing operation is done.

The crankshaft grinding machine is centreless, vibration-free equipment which ensures that the centre line of the crankpin is maintained. The crankshaft grinding and crankshaft polishing are done in one setting.
