Instructions for using the 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 the Second Step.
Dismantle the machine and check all spare parts, assemble the Pneumatic Motor in the insitu grinding machine.
Assemble the hardware in the shell, assemble the machine on the crank pin, and rotate the gear manually.
Assemble the machine’s upper and lower caps and recheck all bolts.
Connect the Air Hose Pipe to the 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.
