RA Power Solutions have been working on high-capacity diesel engine overhaul, repair, and maintenance and grinding of crankshaft for the last 44 years. During our work on engines on board a vessel or in large engineering plants, we have observed that the incidents of crankshafts getting damaged due to accidents are getting very often.
As we are aware that the crankshaft is the heart of the engine by means of connecting rod the crankshaft converts reciprocating motion to the liner movement which drives the engine. RA Power Solutions have the process, technology, and onsite crankshaft grinding machines ranging from 35 mm to 700 mm and crankshaft repair is now possible without disassembly of the crankshaft from the engine. The repair of the crankshaft is possible irrespective of its length and weight as we have the equipment available up to 700 mm in terms of diameter.
The crankshaft in general has various applications including diesel generating sets and marine engines typical areas of crankshaft applications are as follows:
Compressors
Railway vehicles/engines
Power generators
Forging hammers
Pumps
Marine engines, etc.
Crankpin After Accident
Crankpin After Serious Accident
The crankshaft of high-capacity engines used for marine and land-based applications are of forged steel. RA Power Solutions has experienced technicians, and advanced technology equipment i.e. in situ crankshaft grinding machine to maintain the dimensions and tolerances strictly as per the manufacturer’s specifications and recommendations. Major parameters maintained after crankshaft grinding and repair and grinding of crankshaft are as follows:
Taper and ovality can be maintained within 0.02/0.03 mm or less as per the requirement of the engine manufacturer.
The portable in situcrankshaft grinding machine used by RA Power Solutions technicians is capable of maintaining a surface finish of far less than 0.03 RA value.
The high surface finish value after grinding of crankpin and main journal diameter of the crankshaft enhances the life of connecting rod and main bearings considerably.
Inspection of Crankpin Before Repair & Grinding
Inspection of Crankpin is in Process
The radius profile of both the end of the crankpin or main journal and the lubricating oil profile is maintained strictly as per the original profile.
The straightness/runout of the crankshaft is checked, and the crankshaft is straightened if required by the peening process.
Counterweight can be replaced in case of damage and supporting threads are repaired onsite.
Machining of Crankshaft by In situ Crankshaft Grinding Machine
During our work of more than four decades, we have repaired more than 10,000 crankshafts used for different applications. All the repairs are executed with a guarantee. We are an ISO-certified company and also meet the standards requirements like DNB, Lloyd’s, etc. All our technicians possess Indian CDC and can join the vessel in a short time in any part of the world.
Crankpin After Repair by In situ Crankshaft Grinding Machine
Grinding of Crankpin is in Process
Crankshaft grinding and repair are essential processes in the field of engine maintenance and precision engineering. The crankshaft, being a crucial component in any engine, requires meticulous attention to ensure its optimal performance. At RA Power Solutions, we specialize in main bearing machining, grinding of crankshaft, and in situ crankshaft grinding.
In situ crankshaft grinding machine is an ideal solution for the repair of a damaged crankpin journal of a diesel engine without dismantling the crankshaft.

In Situ Crankshaft Grinding Machine
Instructions for using onsite crankshaft and cylindrical Grinding Machine:-
Inspection:
Check CR Pin Size, Hardness, DP Test, or Magnetic Particle Test and
Deflection, in case all reports are good after that, take Second Step.
Dismantle the machine and check all spare parts, assemble the Pneumatic Motor in insitu grinding machine.
Assemble the hardware in the shell assemble the machine on the crank pin and rotate gear manually.
Assemble the machine upper and lower cap and recheck all bolts.
Connect Air Hose Pipe to Pneumatic Motor.
After the machining process first round is complete, dismantle the in situ grinding machine and check the size of the Crank Pin.
Follow the same steps to complete the job.
Before maintaining the final size, check hardness, MPI, or DP Test & take Maximum Reading by Micrometer.
Note: Before the final size check, reset the outside micrometer and take the dimensions again.
Maintenance & Cleaning:-
In order to properly maintain machine tools, it is very important to perform maintenance checks periodically of all accessories. The author is Mr. Raj Shahani, Managing Director of the company. He has forty years of experience in providing onsite engine repair services to companies all over the world.After extensive research and field trials, he has developed in situ crankshaft grinding and polishing machine to make the repair process easy and cost-effective.

RA Power Solutions has executed successfully the crankshaft grinding of 6 pins on board a vessel at Dumai/Lubuk Gaung Port, Indonesia of MAN B&W STX 6L23/30H Engine.
In this case, crankshaft grinding was required because all the CR pins having a standard diameter of 185 mm developed taper and ovality. Out of 6 CR pins, not even a single pin was seized or crack was developed.
Crankshaft Deflection and MPI Test Under Process
The above observations show that the engine users should periodically get the crankshaft calibrated and go for grinding and polishing as the crankshaft develops taper and ovality due to continuous running.
To execute the above job, RA Power Solutions Pvt. Ltd. used a crankshaft grinder which is lightweight, and the crankshaft grinder was taken to the site. RA Power Solutions has sold more than 60 crankshaft grinding machines all over the world.
