Product Description
Komatsu Travel Motor PC40 EXCAVATORS FINAL DRIVE ASSEMBLY
Product Overview
This Final Drive Assembly for the Komatsu PC40-7 crawler excavator is a complete, high-torque travel propulsion unit developed for 4-ton-class machines used in general construction, infrastructural maintenance, and site preparation. Each assembly combines a compact axial piston hydraulic motor with a multi-stage planetary reduction gearbox to provide strong tractive force, precise speed control, and dependable operation across mixed terrain.
The two part numbers cover both sides of the machine:
- 20T-60-76710 - Left-hand final drive
- 20T-60-78120 - Right-hand final drive

Regional Application & Market Suitability
- North America & Europe: Sealing and materials are selected for reliable operation in cold-weather starts and wet, muddy conditions typical of excavation and utility work.
- Southeast Asia & Oceania: Floating seals and heavy-duty wipers resist abrasive tropical soils, clay, and mud found in drainage and foundation works.
- Middle East & Africa: High-temperature seals and reinforced housing surfaces protect against sand abrasion and thermal stress in arid climates.
Key Features & Performance Advantages
- Consistent Power Output: The axial piston motor design delivers high starting torque and smooth modulation for confident travel on slopes, soft ground, and uneven surfaces.
- Long-Life Planetary Gearing: All gears are manufactured from heat-treated alloy steel with precision-ground teeth, ensuring balanced load sharing and reduced wear over extended service intervals.
- Side-Specific Configuration: Separate left-hand and right-hand assemblies guarantee correct rotation and orientation, simplifying installation and preventing misapplication.
- Sealed for Harsh Environments: Dual floating seals and robust dust wipers provide a strong defense against water, mud, and debris, keeping internal components clean and lubrication intact.
- Plug-and-Play Fit: Designed to match original PC40-7 mounting points and hydraulic connections for a seamless installation with minimal downtime.
Expert Maintenance Guidance
- Inspect Drain Lines: Periodically check the case drain hoses for kinks, wear, or blockages. Restricted flow can create back pressure that damages motor seals or internal rotating groups.
- Use Correct Gear Oil: Always fill the planetary housing with the recommended extreme-pressure gear oil. Under normal operation, replace it every 250-500 hours; reduce the interval to 250 hours for severe duty cycles. Watch for metal particles in drained oil as an early warning sign of component wear.
- Replace Mounting Bolts: When reinstalling, use new bolts of the correct grade, apply thread locking compound, and torque to factory specifications to withstand continuous vibration and shock loads.
- Prime Before Use: After installation or service, fill the housing with clean hydraulic oil, run the machine at low idle, and cycle the tracks in both directions to purge air and fully lubricate all planetary components.
