Hitachi Construction Machinery ZX200 EX200-5 EX210K-5 EXCAVATORS FINAL DRIVE

The Final Drive Motor (Part No. 9134825) for Hitachi ZX200, EX200-5, and EX210K-5 hydraulic excavators is a heavy-duty, high-torque travel propulsion unit engineered for medium-to-heavy construction, quarrying, and general earthmoving applications in the 20-ton machine class.

This assembly integrates a high-displacement axial piston hydraulic motor with a rugged multi-stage planetary reduction gearbox, delivering exceptional tractive effort and reliable travel performance under sustained heavy-load conditions. Designed as a direct OEM replacement, this motor ensures precise fitment and factory-specified hydraulic performance for all three machine models.

• North America & Europe: Engineered for heavy civil construction, road building, and infrastructure projects, with reinforced housing and enhanced sealing to withstand extreme temperature variations, abrasive materials, and continuous high-cycle operation.
• Southeast Asia & Oceania: Equipped with heavy-duty floating seals that resist ingress of highly abrasive laterite soils, clay, and tropical mud common in mining, quarrying, and large-scale earthworks projects.
• Middle East & Africa: High-temperature seals and corrosion-resistant materials protect against sand erosion, thermal stress, and airborne particulate contamination in arid desert and semi-arid environments.

• High-Torque Axial Piston Motor: The swashplate-type motor design delivers strong starting torque and smooth speed control, enabling efficient tracking on steep slopes, soft ground, and uneven terrain typical of 20-ton-class excavator applications.
• Multi-Stage Planetary Reduction: The gearbox employs case-hardened alloy steel planetary gears with precision-ground tooth profiles, ensuring uniform load distribution across multiple stages and maximizing service life between major rebuilds.
• Cross-Model Compatibility: Precision-engineered to fit the Hitachi ZX200, EX200-5, and EX210K-5 models with identical mounting dimensions, pilot bores, spline connections, and hydraulic port locations, providing exceptional flexibility for mixed fleet maintenance and inventory management.
• Heavy-Duty Structural Integrity: The ductile iron housing features reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading from tramming over rough terrain. Dual-cone floating seals with heavy-duty dust wipers provide robust protection against contamination in the harshest environments.
• Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Hitachi specifications, enabling seamless installation with minimal machine downtime.
