Diesel engines installed on vessels, diesel power plants, and heavy industry operate continuously non-stop except the stoppage of operation for maintenance purposes. It is obvious that due to the continuous running of diesel engines and reciprocating equipment, the crankshaft develops the following problems.
- Development of taper and ovality beyond the specified limits.
- Development of rough surface of crankpin and main journal diameter.
- Line marks, pitting marks due to use of bad quality oil or use of lubricating oil for prolonged hours.
- Development of bearing line marks, pitting marks due to failure of bearings, or removal of bearing top layer.
- Development of cracks due to accident or failure of crankpin and main journal bearing.
- Increase or decrease in hardness more than the limits stipulated in the engine maintenance manual.
- Loss of alignment of crankshaft and variation in deflection reading.
- Damage of radius fillets due to failure of bearings.
- Damage of counterweight and counterweight bolts due to an accident.
