Komatsu WA380-3H ACTIVE(S/N WA380H20501-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WA380-3H ACTIVE is a mid-size wheel loader designed for high-productivity earthmoving, quarrying, and stockpiling applications. This machine belongs to the WA380 series, featuring a Komatsu S6D108 engine (4-cycle, water-cooled, 6-cylinder, direct injection with turbocharger). The unit operates in a weight class typically around 17.7 tonnes (approx. 39,000 lbs) and is configured with a bucket capacity of approximately 3.0 to 3.2 m³ (3.9 to 4.2 yd³). It serves as a predecessor to later generations like the WA380-6 and WA380-8.
Across generations, Komatsu has transitioned from the mechanical focus of the -3 series toward the advanced electronic integration seen in the -8 series, which utilizes SmartLoader Logic and hydrostatic transmission options. The WA380-3H ACTIVE remains a critical asset in the used market due to its robust S6D108 powertrain and high resale value. For fleet managers, this machine represents a balance of proven mechanical reliability and the foundational telematics capabilities provided by KOMTRAX, making it a staple for mid-size construction and municipal fleets.

Servicing the WA380-3H ACTIVE(S/N WA380H20501-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize Komatsu Oil Wear Analysis (KOWA) at every major interval to monitor engine oil, hydraulic fluid, and coolant. Analyze for wear metals like iron or copper, and contaminants such as silicon or sodium. Use KOMTRAX telematics to track fuel consumption, load frequency, and fault codes remotely. This data-driven approach allows for adjusting service intervals based on actual machine condition rather than fixed hours.
Corrective & Common Repairs
Monitor the fuel system for low transfer pump pressure; check the lift pump screen and inspect the injection pump check valve if hard starting occurs. For electrical issues, use diagnostic codes to identify faulty sensors or wiring corrosion. If the machine fails to move, inspect transmission and axle components. Regularly check hydraulic hoses for cracks or leaks to prevent sudden loss of function.
Overhaul & Rebuild Points
Plan major component evaluations at 2,000-hour intervals. Focus on the turbocharger inspection and valve adjustments. During heavy rebuilds, evaluate the transmission, torque converter, and hydraulic pump efficiency. Check structural integrity of the boom, bucket links, and pins for excessive play. For Tier 4 compliant successors, ensure the Diesel Particulate Filter (KDPF) is inspected for restriction at approximately 4,500 hours.
Seasonal & Environment Servicing
In dusty environments, prioritize frequent air filter element cleaning and radiator fin inspections to prevent overheating. During cold weather operations, ensure the engine pre-heating system is functional and check for fuel waxing. In high-moisture or muddy conditions, increase frequency of grease applications to all articulation points, pins, and bushings to prevent premature wear from abrasive contaminants.

| CA234 | Engine overspeed | Improper throttle calibration, excessive engine load cycle, or operator misuse | Verify throttle calibration and review engine load conditions |
| CA441 / CA442 | Battery voltage too low (CA441) or too high (CA442) | Alternator failure, battery degradation, or faulty voltage regulator | Replace the alternator or battery; inspect the voltage regulator |
| AA10NX | Air cleaner clogging | Accumulated dust or debris in the air filter element | Replace the air filter |
| B@BCNS | Engine coolant overheating | Low coolant level, radiator fin blockage, or fan belt failure | Check radiator fins, fan belt, and coolant level |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.
