Instructions for using on site 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 and 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 machining process first round is complete, dismantle the in situ grinding machine and check size of Crank Pin.
Follow same step to complete job.
Before maintaining final size, check hardness, MPI or DP Test & take Maximum Reading by Micrometer.

Note: Before final size check, reset outside micrometer and take dimension again.

Recommendation for reconditioning of Crankshaft:

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

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