I. Installation Precautions
Heavy-Duty Lifting: Given the massive weight of the PC2000-8 assembly, utilize high-capacity lifting equipment and ensure the chassis is securely supported.
Hydraulic Air Bleeding: Thoroughly clean all interfaces before connection. After installation, air bleeding and pre-filling via the motor’s bleed plug are mandatory before startup to prevent motor seizure caused by dry rotation.
Torque & Sealing: Mounting bolts must be treated with thread locker and tightened to ultra-high torque specifications. Closely inspect the floating seal contact surfaces to ensure no damage occurred during assembly.
II. Troubleshooting Solutions
Tracking Deviation or Weakness: Prioritize measuring the travel pilot valve pressure. If pressure is normal, the issue is typically internal leakage caused by a worn distributor plate in the motor.
Final Drive Abnormal Noise: This often indicates abnormal gear meshing or bearing failure. Perform an immediate oil analysis; if significant metallic fragments are found, a full teardown is required to prevent housing destruction.
Leakage Management: Oil leaks at the sprocket hub usually signify floating seal failure. Immediate replacement is critical to prevent abrasive contaminants from entering and destroying the precision gear train.
