Hitachi Construction Machinery ZX870LC-3 final drive YB60000075 9251681 travel motor EXCAVATORS FINAL DRIVE ASSEMBLY FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY

The Final Drive Motor (Part Nos. YB60000075 / 9251681) for the Hitachi ZX870LC-3 hydraulic excavator is a large-displacement, high-torque travel propulsion unit engineered for heavy-duty mining, quarrying, large-scale earthmoving, and major infrastructure construction in the 80-ton machine class.

• North America & Europe: Engineered for large-scale infrastructure, quarrying, and heavy civil construction with reinforced housings and heavy-duty sealing for extreme temperature fluctuations and continuous high-cycle operation.
• Southeast Asia & Oceania: Equipped with heavy-duty floating seals that resist ingress of abrasive laterite soils, clay, and tropical mud in high-humidity environments.
• Middle East & Africa: High-temperature seals and corrosion-resistant materials protect against sand erosion and thermal stress in extreme arid desert conditions.

• Massive High-Torque Motor: Large-displacement swashplate piston motor delivers immense starting torque and precise speed control for challenging terrain.
• Multi-Stage Heavy-Duty Planetary Reduction: Case-hardened, precision-ground alloy steel planetary gears with induction-hardened shafts and bearings for maximum service life.
• Model-Specific Engineering: Precision-engineered to match exact mounting dimensions, spline connections, and hydraulic porting of Hitachi ZX870LC-3.
• Heavy-Duty Structural Integrity: High-strength ductile iron housing with reinforced ribbing and stress-relieved construction to resist structural fatigue.
• Precision OEM Replacement Fit: All mounting bolt patterns and connections match original Hitachi specifications for straightforward installation.

• Hydraulic System Care: Routinely inspect case drain lines for restrictions and maintain strict hydraulic fluid cleanliness standards.
• Gear Oil Management: Change oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications.
• Mounting Bolt Protocol: Always fit new high-strength bolts with thread locking compound torqued to factory specifications.
• Pre-Operation Priming Procedure: Fill motor housing with clean hydraulic oil and run at low idle before engaging heavy production loads.
