Positioned between compact tool carriers and full-size production machines the WA380-6 delivers exceptional versatility for aggregate plants construction sites, municipal road maintenance, and general material handling. Its balanced bucket capacity travel speed, and maneuverability make it the most commonly sighted loader across commercial job sites globally.\nPowered by the Komatsu SAA6D107E turbocharged and aftercooled six-cylinder diesel engine, the WA380-6 delivers approximately 260 horsepower with Tier 3 emissions compliance. The electronically managed common-rail fuel system optimizes injection timing and quantity for minimal fuel consumption while maintaining strong lugging power in the pile. The three-element torque converter with Komatsu clutch-type powershift transmission provides smooth acceleration and controlled deceleration through all four forward and three reverse gears.\nSerial number H60051 and above incorporates the final production refinements for the six generation including updated emission system components improved sealing gaskets, and refined hydraulic valve spool geometry for smoother boom and bucket control. The ROPS-certified cab provides excellent all-round visibility through large tinted glass and features an adjustable air suspension seat for operator comfort through demanding work cycles.\nSERVICE \u0026amp; REPAIR SCOPE:\n- SAA6D107E engine cylinder head timing gear overhaul\n- Common-rail fuel injector removal coding and bench test\n- VGT variable geometry turbocharger actuator calibration\n- Clutch-type powershift transmission clutch pack piston overhaul\n- Torque converter stator turbine and impeller inspection\n- Front and rear axle planetary hub reduction gear service\n- Articulated frame center pivot pin and bushing replacement\n- Work hydraulic system boom and bucket cylinder rebuild\n- Steering load sense priority valve adjustment and testing\n- Wet disc service brake stack measurement and piston replacement\n- Electrical system alternator starter harness harness connector pinout\n- HVAC compressor clutch replacement and refrigerant service\nTECHNICAL SPECIFICATIONS:\n- Manufacturer: Komatsu\n- Model: WA380-6\n- Engine: SAA6D107E, 6-cylinder turbo diesel, common-rail\n- Rated Output: Approx 260 HP\n- Bucket Capacity: 3.0 to 3.8 cubic meters\n- Transmission: 4F3R clutch-type powershift\n- Serial Number: H60051 and above\nDIAGNOSTIC INFORMATION:\n- Engine fault code readout via machine monitor panel\n- Transmission clutch pressure measurement procedure\n- Hydraulic system relief valve cracking pressure verification\n- Turbo actuator position sensor calibration\n- Wet disc brake drag torque measurement\n- Battery parasitic drain test and charging output check\n- KOMTRAX data monitoring and error interpretation\nILLUSTRATIONS \u0026amp;\u003c\/p\u003e\n\u003cp\u003eInstant download — no shipping, no waiting.
