Analisa Kerusakan Dan Perbaikan Power Train Pada Unit Excavator Kobelco SK200-5

Abstract

Power train is a drive mechanism that works together to transmit power from the engine to the final drive, how the power train works when the engine rotates drives the main pump to circulate pressurized oil from the tank to the control valve and is passed on to the travel motor to drive the final drive. A visual inspection of the components is carried out to ensure that the power train components are damaged which causes the unit to stutter, along with several visual inspections of the power train components including checking the Control Valve, Idler, and Motor Travel. Based on the results of checking the power train has damage to the worn sprocket teeth. This damage is caused by soil or mud that sticks and hardens resulting in erosion of the components which makes the components wear out, the service life has exceeded the limit. Repairs to this sprocket component require replacing it with a new part because the Kobelco Sk200-5 excavator uses a solid type sprocket
