3. Maintenance Tips – Extend the Life of Your Center Joint
-
Regular lubrication – Grease the swivel joint every 250–500 working hours to reduce friction and wear.
-
Inspect seals frequently – Check for oil leaks around the center joint. Worn seals can cause cross-circuit contamination and pressure loss.
-
Use clean hydraulic oil – Contaminated oil accelerates seal and bore damage. Replace filters on schedule.
-
Avoid overloading – Operating beyond rated pressure may damage internal passages and seals.
-
Listen for unusual noises – Grinding or clicking sounds during rotation may indicate internal damage – replace the joint promptly.
-
Store spare parts properly – Keep in a dry, clean environment with anti-rust protection before installation.
Following these tips can double the service life of your LiuGong GLG920E/GLG922E center joint. For technical support, contact Hongtengda Parts – our repair workshop is always ready to help.
