Product Description
Komatsu D155AX-6 D155AX-7 D155AX-8 Final Drive Assembly 17A-27-00135
The 17A-27-00135 Final Drive Assembly is a heavy-duty track propulsion unit engineered specifically for Komatsu D155AX-6, D155AX-7, and D155AX-8 bulldozers in the 35-40 ton machine class. This integrated drivetrain combines a high-displacement axial piston travel motor with a multi-stage planetary reduction gearbox, delivering the exceptional drawbar pull and structural integrity required for heavy dozing, ripping, and land clearing operations in mining, quarry, and large-scale earthmoving applications.

Regional Application & Market Suitability
- North America & Europe: Upgraded with reinforced planetary carriers and oversized taper roller bearings to handle continuous high-load cycles in coal mining overburden removal, highway construction, and heavy landfill operations
- Southeast Asia & Oceania: Equipped with heavy-duty Duo-Cone floating seals and corrosion-resistant output shaft coatings to prevent contamination from abrasive volcanic soils, tropical clay, and coastal saline environments in plantation development and marine reclamation projects
- Middle East & South America: Enhanced thermal management through optimized oil circulation galleries and enlarged heat dissipation surfaces on the motor housing, maintaining stable operating temperatures during extended ripping and dozing operations in desert conditions exceeding 50°C ambient temperature
Expert Maintenance Guidance
- Hydraulic System Care: Routinely monitor case drain flow rate during every service interval; flow exceeding 18 L/min indicates internal motor wear requiring immediate teardown and rebuild inspection. Replace hydraulic return filters every 200 operating hours and pilot filters every 400 hours in severe dust conditions to prevent contaminant circulation through travel motor circuits
- Gear Oil Management: Drain and replenish planetary gearbox oil every 500 operating hours under moderate conditions, or every 250 hours in severe dust, high-temperature, or high-moisture environments. Use SAE 85W-140 API GL-5 gear oil for maximum load-carrying capacity under heavy shock loading; verify floating seal compatibility before substituting synthetic oils
- Mounting Hardware Protocol: Always install new OEM-specification mounting bolts with high-strength thread locker compound rated for extreme vibration applications. Tighten in a three-stage cross-pattern sequence at 40%, 70%, and 100% of specified torque to achieve uniform clamping force and prevent housing distortion under severe load conditions
- Pre-Operation Priming Procedure: Before initial engine start following final drive replacement, completely fill the travel motor housing with clean ISO VG 68 hydraulic oil through the uppermost port. Rotate the output sprocket manually in both directions using a pry bar to expel trapped air from piston chambers, then verify oil level before startup to prevent catastrophic dry-start damage to piston shoes, cylinder block, and valve plate surfaces
