by RA Power Solutions RA power solution

Diesel engines installed on vessels, diesel power plants and heavy industry operate continuously non-stop except the stoppage of operation for maintenance purpose. It is obvious that due to continuous running of diesel engines and reciprocating equipments, the crankshaft develops 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.
