Swing Motor Troubleshooting

1) The gap between the plunger and the cylinder plunger hole has increased, resulting in severe leakage. The plunger needs to be replaced.

2) The return spring has become worn out and its elasticity has decreased, causing the high and low pressure oil circuits of the cylinder to be interconnected. The spring needs to be replaced.

3) The wear of the slipper and the plunger ball has accelerated the dry friction between the slipper and the pressure plate, leading to an increase in the rotation resistance. Repair or replacement is required.

4) The bearing of the rotating motor is damaged, and the bearing positioning is ineffective. The specified type of bearing needs to be replaced.

5) The sealing surface of the safety valve has worn out and needs to be repaired or replaced.

6) The sealing element of the parking brake hydraulic cylinder has aged, failed, and leaked oil, causing the brake to not be fully released and the rotation resistance to increase. The sealing element needs to be replaced.

7) The distribution plate and the oil distribution surface of the cylinder have worn out, resulting in internal leakage, weak rotation, and require repair or replacement.

8) The sealing element has been abraded, aged, or failed and should be replaced.
