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.

Crankshaft Grinding Machine | Crankshaft Grinder | Global Onsite Repairs – RA Power Solutions

Engine population is rapidly increasing for the shipping industry, power plants, and various applications. In most cases, engines are used not only for emergency purposes but as a base load. The continuous running of the diesel engine results in wear and tear of the crankpin and main journal of the crankshaft. In certain cases, taper and ovality more than the permissible limit is developed in the crankpin and the crankshaft main journal.

**Inspection of Engine Before Grinding**

The disassembly of the crankshaft from the main engine and sending it to the designated workshop is a lengthy process. This is now outdated. RA Power Solutions having the experience of more than four decades in the repair of crankshafts have developed a portable, lightweight engine crankshaft grinding machine and onsite crankshaft grinding machine which can be taken to the site as accompanying baggage. The onsite crankshaft grinding machine has the following features:

Light in weight can be carried to the site easily.
