The 707-99-68470 Arm Cylinder Seal Kit is manufactured to OEM specifications for the arm (stick) hydraulic cylinder used on selected Komatsu construction equipment. This complete hydraulic cylinder overhaul kit contains precision-engineered rod seals, piston seals, wear rings, guide rings, backup rings, O-rings and dust seals designed to restore hydraulic sealing performance, eliminate oil leakage and maintain optimum hydraulic pressure. Manufactured from high-quality sealing materials, it provides dependable sealing performance in demanding construction, earthmoving, quarrying and mining environments.
The arm hydraulic cylinder controls the extension and retraction of the excavator stick, enabling accurate digging, trenching, grading and loading operations. Continuous exposure to high hydraulic pressures, heavy digging forces and harsh site conditions gradually wears the cylinder seals. Worn seals may cause hydraulic oil leakage, stick drift, reduced digging force, slow cylinder movement and internal pressure bypass. Replacing the complete seal kit restores sealing integrity, improves hydraulic efficiency and helps extend the service life of the hydraulic cylinder while reducing equipment downtime.
