| S. No | Crankpin Details | |
| 1. | Engine Make | MAK |
| 2. | Engine Model | 8CM32C |
| 3. | Engine Number | #03 |
| 4. | Crankpin Diameter Standard | 280.00 MM |

The dimensional inspection of the damaged and seized crankpin number #7 was conducted.
- Dimensional checks revealed:
Minimum Diameter: 279.68 mm
Maximum Diameter: 280.00 mm
Ovality: 0.32 mm
|
|
|
Apart from an ovality of 0.32 mm, the crankpin exhibited deep scoring marks and a rough surface, which was developed due to seizure of the bearing.
- The hardness was checked and showed marginally higher values in certain spots.
- MPI for crack detection was undertaken and revealed no cracks or abnormalities.
- The remaining crankpins were also inspected for taper and ovality and all within acceptable limits.
Action taken for the successful repair of the crankshaft of MAK 8CM32C :
i) The grinding of crankpin number #7 was ground to an undersize of 3 mm; this was done as the deep line marks were present at every step.
They got cleared only after grinding the crankpin to 3 mm undersize, resulting in a final diameter of 277.00 mm.
ii) The remaining crankpins were polished to improve surface finish and reduce the ovality by 0.01/0.02 mm.
The above job of crankshaft repair of MAK 8CM32C has been executed strictly as per the requirements of the manufacturers and the tolerance specified.
