Basic Parameters & Introduction
"This
O-ring seal kit fits part numbers 4C8253 / 4C8253 and is widely used for excavator hydraulic systems, pumps, valves, and connection sealing. Pump numbers and compatible models should be confirmed against the OEM parts catalog, as configurations may vary. The kit includes multiple O-ring sizes.Please verify machine serial number, pump number, and required seal sizes before ordering to avoid mismatching."

Maintenance Tips
It is recommended to replace all O-rings during hydraulic system overhaul, pump/valve disassembly, or seal service. Under normal conditions, inspect seals every 2,000 working hours or once a year. In high-temperature, dusty, humid, heavy-duty, or continuous operating environments, shorten the interval to 1,000 hours. If oil leakage, pressure drop, hardening, cracking, permanent deformation, or loss of elasticity is found, replace immediately. Store spare seals away from direct sunlight, moisture, heat, and ozone; check elasticity before use if stored for more than 3 years.

Installation Tips
Before installation, thoroughly clean the sealing groove and remove burrs, rust, and old seal residue. Confirm the O-ring size matches the groove. Apply a small amount of hydraulic oil or compatible grease; avoid dry installation. Do not over-stretch, twist, or use sharp tools that may damage the sealing surface. After fitting, ensure the O-ring sits evenly in the groove without rolling or pinching. Tighten bolts diagonally and evenly to the standard torque to prevent local overload. Before full operation, run at low speed to vent air and check all sealing points for leakage.
