4. Setup and Installation
Installation of the swing motor requires specialized knowledge and tools. It is recommended that installation be performed by certified personnel.
- Preparation: Park the excavator on a level surface, engage the parking brake, and lower all attachments to the ground. Turn off the engine and disconnect the battery. Relieve any hydraulic pressure in the system.
- Access: Depending on the excavator model, access the swing motor compartment. This may involve removing covers or panels.
- Drain Hydraulic Fluid: Place a suitable container beneath the swing motor and carefully disconnect the hydraulic lines to drain the fluid. Note the orientation of all lines for reinstallation.
- Remove Old Motor: Unbolt the old swing motor from its mounting points. Use appropriate lifting equipment to safely remove the motor.
- Inspect Mounting Surface: Clean and inspect the mounting surface for any damage or debris. Ensure it is flat and free of contaminants.
- Install New Motor: Carefully position the new FARWAY swing motor onto the mounting surface using lifting equipment. Align the bolt holes and secure the motor with the appropriate fasteners, tightening to the manufacturer's specified torque.
- Reconnect Hydraulic Lines: Reconnect all hydraulic lines to the new motor, ensuring correct orientation and tight connections. Replace any worn O-rings or seals.
- Refill Hydraulic System: Refill the hydraulic system with the correct type and amount of hydraulic fluid as specified by the excavator manufacturer.
- Bleed Air: Follow the excavator manufacturer's procedure to bleed air from the hydraulic system.
- Test: Reconnect the battery. Start the excavator and perform a functional test of the swing mechanism in a controlled environment, checking for leaks or abnormal operation.
