Calibrated and modern instruments are used to undertake preliminary inspection of the crankshaft as follows:
1. Dimensional inspection to check taper and ovality
2. Crack detection by MPI/ultrasound or dye penetrant
3. Hardness test
4. Surface test to check surface roughness
5. Inspection to check the straightness of the crankshaft
6. Lube oil and radius fillet profile check
7. Visual inspection

All the readings and observations are recorded in the inspection format, and onsite repair planning is done in consultation with our senior Engineer.

After inspection, grinding, and repair of the crankshaft, the following parameters are achieved:
1. Taper and ovality of the crankpin and main journal after grinding and polishing can be achieved within 0.02 mm.
2. The lubrication oil hole and radius fillet profile can be given as per the original profile.
3. The presence of crack and hardness readings are taken and recorded.
4. Straightness and run-out are maintained as per the manufacturer’s specifications. A surface finish of less than 20 RA values can be maintained and achieved.
