Reasons for hydraulic cylinder oil leakage
During normal use, we should also pay attention to regularly checking the connection parts such as threads and bolts, and tighten them immediately if any looseness is found. Because looseness in these areas can also cause hydraulic cylinder oil leakage, which is easy to understand for personnel engaged in excavators.
We also need to pay attention to regularly lubricating the connection parts to prevent rust or abnormal wear in an oil-free state. Especially for some parts with rust, we should handle them in a timely manner to avoid hydraulic cylinder oil leakage caused by rust.
