Swing Motor YN15V00077F1 / YN15V00055F1

What this part does

Swing motor row for the 20-tonne class carrying three numbers; quote from the unit's own plate and we confirm which applies.

Failure symptoms we hear most often

• Gradual loss of performance in the circuit it serves
• Abnormal noise, heat or vibration once the machine is at working temperature
• Metal or sludge in the oil when the filter is cut open
• Fault code or warning on the monitor that will not clear after reset

None of those four on their own prove the part has failed. Send us the serial number and a photo of the old unit and we will tell you whether to replace or repair — even when the answer is repair.
