Product Detail

Product Description: 860129457 Arm Cylinder Seal Kit for XCMG XE215CLL Excavator

The 860129457 Arm Cylinder Seal Kit is a genuine OEM hydraulic seal repair kit designed specifically for the arm (stick) cylinder of the XCMG XE215CLL crawler excavator. The XE215CLL is a long-arm variant of XCMG’s popular 21-ton class excavator, widely used in dredging, slope finishing, deep excavation, and large-scale earthmoving applications where extended reach is required.

The arm cylinder is one of the most heavily utilized hydraulic actuators on an excavator, responsible for extending and retracting the stick to move the bucket toward or away from the machine. High cycle counts, extreme pressure spikes, and contamination exposure make the arm cylinder seals a critical wear component. Over time, worn or damaged seals lead to internal leakage, reduced digging force, slow cylinder drift, oil overheating, and increased fuel consumption.

Kit contents include (typical for arm cylinder reseal):

Rod seal (primary and secondary)

Piston seals (buffer and main)

Wiper/scraper seal (dust seal)

Support rings / back‑up rings

O‑rings (static and dynamic)

Wear rings / guide rings (if applicable)

Applicable machine: XCMG XE215CLL excavator (serial number ranges may vary; always verify against your machine’s cylinder part number).
