- Surface test to check surface roughness
- Inspection to check the straightness of the crankshaft
- Lube oil and radius fillet profile check
- 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.
