Replacing the 380300747 rotary joint on an XCMG Grader requires careful attention to safety, procedure, and compatibility. Below are key considerations:
Safety First
Ensure the grader is parked on a level surface with the engine turned off and the hydraulic system fully depressurized.
Use proper PPE to prevent injuries from hydraulic fluid or sharp edges.
Hydraulic System Preparation
Drain hydraulic fluid from the relevant circuit to minimize leaks.
Clean the surrounding area to prevent contamination of the hydraulic system.
Disassembly & Installation
Label hoses and connections before removal to ensure correct reassembly.
Inspect seals, O-rings, and hoses for wear-replace if damaged.
Apply hydraulic-compatible grease to seals for smoother installation.
Post-Installation Checks
Refill hydraulic fluid and bleed air from the system to prevent cavitation.
Test the rotary joint under low pressure first, then gradually increase to full operating pressure.
Monitor for leaks, unusual noises, or restricted movement-address immediately if detected.
