Product Description
Komatsu PC350-7 PC350LC-7 Heavy-Duty High-Torque Final Drive Assembly
The Komatsu PC350-7 / PC350LC-7 Final Drive -- Part No. 207-27-00373 is a heavy-duty travel drive assembly designed for 35-ton class crawler excavators working in demanding excavation, quarrying, road construction, and infrastructure applications. This unit combines a hydraulic travel motor with a precision planetary reduction gearbox to deliver strong tractive force, smooth machine travel, and dependable performance under high-load operating conditions.
Built as a direct replacement final drive for PC350-7 and PC350LC-7 models, it is engineered to match the required mounting interface, sprocket connection, hydraulic port layout, and travel performance characteristics, helping reduce installation time and machine downtime.

Regional Application & Market Suitability
The Komatsu PC350-7 and PC350LC-7 excavators are deployed across diverse demanding global job sites. Our final drive unit is regionally optimized to meet specific operational challenges:
- North America & Europe: Engineered for heavy civil construction, road building, and quarry applications, with reinforced housing and enhanced sealing to withstand high-frequency use, cold-weather startups, and abrasive winter road treatments.
- South America & Oceania: Equipped with heavy-duty floating seals that resist ingress of abrasive laterite soils, clay, and tropical mud common in mining, plantation, and large-scale earthworks projects.
- Middle East & Africa: High-temperature seals and corrosion-resistant materials protect against sand erosion, thermal cycling, and airborne dust 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 quarry terrain.
- Multi-Stage Planetary Reduction: The gearbox employs heat-treated alloy steel planetary gears manufactured to tight tolerances, ensuring even load distribution across multiple contact points and extended service life between major overhauls.
- Precision OEM Replacement Fit: All mounting bolt patterns, pilot diameters, spline connections, and hydraulic port locations match original Komatsu specifications for the PC350-7 and PC350LC-7 models, enabling seamless installation with minimal machine downtime.
- Industrial-Grade Structural Integrity: The cast iron housing features reinforced ribbing and stress-relieved construction to resist structural fatigue under continuous shock loading, while dual-cone floating seals protect internal components from contamination.
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 motor rotary group failure or seal damage. Maintain clean hydraulic fluid and replace return filters according to the machine's prescribed service schedule.
- Gear Oil Management: Fill the planetary housing with the recommended extreme-pressure gear oil of the correct viscosity grade. Change the oil every 250-500 operating hours under normal conditions, and every 250 hours in severe applications such as quarry work, demolition, or continuous heavy digging. Examine drained oil for metallic particles as an early diagnostic indicator of gear or bearing wear.
- Mounting Bolt Protocol: When reinstalling the final drive unit, always fit new high-strength bolts. Apply a suitable thread locking compound to the bolt threads prior to torquing to factory specifications, preventing loosening caused by continuous vibration and shock loads during travel and digging operations.
- 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 operational loads.
