Περιγραφή προϊόντων
KOMATSU PC220-7 PC230-7 EXCAVATORS FINAL DRIVE ASSEMBLY 708-8F-00191 FINAL DRIVE MOTOR HIGH QUALITY TRAVEL MOTOR CONSTRUCTION MACHINERY
The Final Drive Unit (Part No. 708-8F-00191) for Komatsu PC220-7 and PC230-7 excavators is a heavy-duty travel propulsion unit engineered for medium-to-large scale construction, quarry, and earthmoving operations in the 22-to-23-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. It is designed as a direct OEM replacement, ensuring precise fitment and factory-specified hydraulic performance for both machine models.

Regional Application & Market Suitability
- 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 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.
Key Features & Performance Advantages
- 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 medium-to-large-scale excavation projects.
- 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: Engineered to fit both PC220-7 and PC230-7 excavators with identical mounting dimensions, pilot bores, spline connections, and hydraulic port locations, providing exceptional flexibility for mixed fleet maintenance and inventory management.
- Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications, enabling seamless installation with minimal machine downtime.
- Industrial-Grade 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.
Expert Maintenance Guidance
- Hydraulic System Care: Routinely inspect case drain lines for restrictions, kinks, or blockages. A restricted drain line can generate excessive back pressure, leading to catastrophic motor rotary group failure or seal damage. Maintain strict hydraulic fluid cleanliness standards and replace return filters at intervals prescribed for heavy equipment.
- Gear Oil Management: Fill the planetary housing with the recommended extreme-pressure gear oil of the correct viscosity grade for heavy-duty applications. Change the oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications such as continuous quarry work, demolition, or heavy ripping. Perform regular oil sampling and analysis to detect metallic particles as an early indicator of gear or bearing degradation.
- Mounting Bolt Protocol: When reinstalling the final drive unit, always fit new high-strength bolts meeting the specified grade. Apply a suitable thread locking compound to the bolt threads prior to torquing to factory specifications, preventing loosening caused by extreme vibration and shock loads during travel and digging cycles.
- Pre-Operation Priming Procedure: Before initial startup or after final drive replacement, fill the motor housing with clean hydraulic oil to purge trapped air pockets. Run the machine at low idle for several minutes, cycling the tracks forward and reverse, to ensure complete lubrication of all planetary components before engaging heavy production loads.
