Hydraulic System Care:
Oil Quality: The arm cylinder is a victim of the hydraulic system's condition. Contaminated oil with tiny abrasive particles will rapidly wear out the piston seals (leading to loss of power) and rod seals (leading to external leaks).
Filter Changes: Adhere strictly to the Caterpillar maintenance guide for changing the hydraulic return filters. The arm cylinder sees rapid pressure changes and shocks, which can cause more internal wear, making clean filters essential.
S·O·S Oil Analysis: Implementing Scheduled Oil Sampling is the best way to monitor the health of the entire hydraulic system. It can warn you of excessive wear metal (indicating pump or cylinder wear), water contamination, and chemical breakdown before a catastrophic failure occurs.
This 259-0871 arm cylinder is used for 385C excavator.
