The 707-99-67095 Arm Cylinder Seal Kit is manufactured to OEM specifications for the arm (stick) hydraulic cylinder fitted to selected Komatsu PC300-7 excavators. This complete overhaul kit includes the precision-engineered sealing components required to restore the hydraulic cylinder to optimum operating condition, preventing internal and external oil leakage while maintaining the hydraulic force needed for demanding excavation applications.
The arm cylinder controls the extension and retraction of the excavator stick, enabling precise digging, trenching, grading and material handling. During continuous operation under high hydraulic pressure, the cylinder seals are exposed to heavy loads, contamination and abrasive conditions. Worn seals can reduce digging efficiency, allow hydraulic bypass and cause cylinder drift. Replacing the complete seal kit restores hydraulic sealing performance, improves control accuracy and extends the service life of the cylinder.

Common Symptoms
- Hydraulic oil leakage from the arm cylinder
