Center Joint (Swivel) YN52F02796P1 / YN52F02330P1

What this part does

Rotary center joint passing oil and pilot pressure into the upper structure. Seal stack failures show as swing creep and oil at the machine's centerline.

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.
