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.

RA Power Solutions has undertaken reconditioning of crankshaft exceeding ten thousand numbers and recommends the following situation for reconditioning of the crankshaft.

Recommendation for reconditioning of Crankshaft:

I) It is recommended to undertake crankshaft repair in case taper and ovality exceed the limit specified in the maintenance manual of the engine manufacturer.
II) In case of an accident, deep line marks or depression are developed.
III) Reconditioning of the crankshaft is recommended in case higher hardness is observed due to the seizer of bearings or any other reason.
IV) Development of surface crack.
V) Loss of alignment.
VI) In certain cases, although the dimensions of the CR Pin and Main Journal are observed within the limit, due to the rough surface observed on the CR Pin and of the Main Journal, the surface requires polishing.

The above suggestions are given for reconditioning of crankshaft. It is always advisable to send photographs and a brief Inspection report to RA Power Solutions for free recommendations as to how to repair Crankshaft successfully.
