The 707-99-68420 Lift Cylinder Seal Kit is manufactured to OEM specifications for the lift hydraulic cylinder used on selected Komatsu construction equipment. This complete hydraulic cylinder overhaul kit includes precision-engineered rod seals, piston seals, wear rings, guide rings, backup rings, O-rings and dust seals required to restore hydraulic sealing performance, eliminate oil leakage and maintain optimum hydraulic pressure. Manufactured from premium sealing materials, it is designed to withstand the demanding operating conditions encountered in construction, quarrying, mining, material handling and earthmoving applications.
The lift hydraulic cylinder is responsible for raising and lowering the working equipment, ensuring smooth and controlled lifting operations while maintaining the machine's hydraulic efficiency. Continuous operation under high hydraulic pressure, heavy loads and harsh working environments gradually wears the cylinder seals. Worn seals can cause hydraulic oil leakage, cylinder drift, reduced lifting capacity, slow lifting response and internal pressure bypass. Replacing the complete seal kit restores sealing integrity, improves lifting performance, protects internal cylinder components and helps minimise costly machine downtime.
Typical Applications

Common Symptoms
- Hydraulic oil leakage from the lift cylinder
