An excavator swing motor is the hydraulic motor that drives upper-structure rotation. It works with the swing reducer, swing bearing and brake system to control smooth slewing movement.
Common symptoms include slow swing speed, weak swing force, oil leakage, abnormal noise, swing drift and overheating. The swing reducer, brake pressure and hydraulic oil condition should also be checked before replacement.
No. The swing motor provides hydraulic rotary power, while the swing reducer reduces speed and increases torque through gears. Some machines use a complete swing motor and reducer assembly.
Please provide the excavator brand, model, part number, motor nameplate photo, spline or teeth count, port layout and mounting face photos.
