Descripción de producto
21T-27-00300 21T-27-00310 Final Drive for Komatsu PC2000-8 Mining Excavator Extreme-Duty Power Unit
The Final Drive Unit (Part Nos. 21T-27-00300 and 21T-27-00310) for the Komatsu PC2000-8 mining-class excavator is an ultra-heavy-duty travel propulsion assembly engineered for large-scale open-pit mining and heavy earthmoving operations in the 200-ton machine class. This unit integrates a massive high-displacement axial piston hydraulic motor with a rugged multi-stage planetary reduction gearbox, delivering immense tractive effort and reliable travel performance under the extreme loads and punishing conditions of continuous mining production. It is designed as a direct OEM replacement, ensuring precise fitment and factory-specified hydraulic performance for the PC2000-8 model.

Regional Application & Market Suitability
The Komatsu PC2000-8 mining excavator is deployed across the world's most demanding extractive industries. Our final drive unit is regionally optimized to meet specific operational challenges:
- North America & South America: Engineered for large-scale open-pit copper, gold, and oil sands mining operations, with reinforced housing and enhanced sealing to withstand extreme temperature variations, abrasive slurry, and continuous high-cycle operation.
- Australia & Oceania: Equipped with heavy-duty floating seals that resist ingress of highly abrasive quartz-rich soils, red dust, and laterite materials common in iron ore and coal mining environments.
- Africa & Middle East: High-temperature seals and corrosion-resistant materials protect against sand erosion, thermal stress, and airborne particulate contamination in arid desert and semi-arid mining regions.
Key Features & Performance Advantages
- Ultra-High Torque Capacity: The large-displacement axial piston motor delivers exceptional starting torque and smooth power transmission, enabling the PC2000-8 to maneuver efficiently on steep mine ramps, soft overburden, and uneven bench floors.
- Heavy-Duty 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.
- Dual Part Number Compatibility: Engineered to accommodate both 21T-27-00300 and 21T-27-00310 specifications, providing flexibility for fleet maintenance and ensuring correct fitment for left-hand and right-hand drive positions with identical mounting dimensions and hydraulic port locations.
- Mining-Grade Structural Integrity: The ductile iron housing features massive reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading from tramming over rough mine floors. 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. Maintain strict hydraulic fluid cleanliness standards and replace return filters at intervals prescribed for mining equipment.
- Gear Oil Management: Fill the planetary housing with the recommended extreme-pressure gear oil of the correct viscosity grade for heavy-duty mining applications. Change the oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications such as continuous mining, ripping, or haul road maintenance. 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 tramming 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.
