Komatsu WA380-3H(S/N WA380H20051-WA380H20500)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WA380-3H (S/N WA380H20051-WA380H20500) is a mid-size wheel loader engineered for quarrying, stockpiling, and industrial material handling. This specific high-lift configuration features an operating weight of 17,420 kg (38,382 lb) and a piled bucket capacity of 3.0 m³ (3.92 yd³). The machine is powered by a Komatsu S6D108 engine, a 4-cycle, water-cooled, in-line 6-cylinder direct injection turbocharged unit.
The WA380 series has evolved through several generations, including the WA380-7 and the Tier 4 Final WA380-8, moving from conventional torque converters to advanced hydrostatic transmissions and SmartLoader Logic. In today's used market, this machine remains a critical asset for fleets requiring a bridge between compact and production-class loaders. Its value is driven by proven reliability in heavy-duty cycles and the availability of high-quality Komatsu genuine parts for rebuild.

Servicing the WA380-3H(S/N WA380H20051-WA380H20500) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA (Komatsu Oil Wear Analysis) at every major service interval to monitor engine oil, hydraulic fluid, and coolant. Analyze for wear metals like iron or copper and contaminants such as silicon or sodium. Tracking these trends via KOMTRAX telematics allows for scheduling repairs before component failure occurs, specifically protecting expensive hydraulic pumps and transmission assemblies from internal damage caused by undetected particle buildup.
Corrective & Common Repairs
Monitor for rising oil temperatures during repeated shuttle work, which may indicate cooling package issues or internal friction. Frequent repair inquiries for this series involve transmission clutch components, axle seals, and hydraulic cylinder kits. When replacing seals or bearings, always inspect mating surfaces and retainers to ensure the repaired assembly does not suffer from immediate interface wear due to improper fitment.
Overhaul & Rebuild Points
Plan major rebuilds around the 2,000-hour milestone, focusing on transmission service and hydraulic oil replacement. During structural overhauls, evaluate the condition of boom pins, bushings, and articulation points for excessive play. For high-lift models, inspect the integrity of the lift cylinders and linkage components to maintain precise bucket positioning and prevent hydraulic drift during heavy loading operations.
Seasonal & Environment Servicing
In dusty quarry or aggregate environments, prioritize cleaning radiator and oil cooler fins to prevent overheating. During winter operations, ensure the cab air filter is replaced alongside engine filters to prevent window fogging caused by restricted airflow. Regularly check all hydraulic hoses for cracks or leaks that could be exacerbated by extreme temperature fluctuations or abrasive material exposure.

WA380-3H(S/N WA380H20051-WA380H20500) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| E03 | Swing parking brake system fault or parking/swing brake system error | Discrepancies in the safety lever system, connectivity issues, or alignment problems. | Immediately inspect the lever's connectivity and alignment. |
| E10 | Engine controller power failure or engine control drive system circuit malfunction | Failure in the engine controller power supply or electrical circuit disruption leading to engine stall. | Inspect ECM power connections, fuses, or ground wires. |
| E11 | Engine control system failure (output power reduction) | System error triggering engine protection mode to prevent damage. | Check coolant temperature, oil pressure, and air filter status. |
| E15 | Engine sensor fault or engine controller serious error | Faults in temperature, fuel pressure, or oil pressure sensors; may cause reduced power or failure to start. | Verify the integrity of engine sensors and their interconnections. |
| CA428 | Fuel moisture sensor feedback voltage too high | Water detected in the fuel system. | Stop and drain the water separator immediately to prevent injector damage. |
| CA451 | Common rail pressure sensor feedback value too high | Malfunction in the rail sensor or an actual overpressure condition in the fuel system. | Diagnose the fuel rail pressure sensor or inspect pump lines. |
| AA10NX | Air filter clogging | Engine air intake is restricted due to debris buildup. | Replace the air filter element. |
| B@BCNS | Engine coolant overheating | High engine operating temperature. | 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.
WA380-3H(S/N WA380H20051-WA380H20500) attachments & work tools
Buckets
Available configurations include high efficiency universal buckets, earthmoving buckets, stockpile buckets with raised bottoms, and mulch grab buckets. Capacities for this class range from 3.2 m³ (4.3 yd³) to 6.5 m³ (8.5 yd³), though specific WA380-3 capacities are noted up to 4.3 yd³ (3.8 m³).
Hydraulic Attachments
The machine supports auxiliary hydraulics for tools such as grapples or forks. A hydraulic flow rate of 71.3 GPM (270 L/min) is available to power rapid cycles and support these attachments.
Mounting & Control Systems
A hydraulic quick-coupler is an available attachment option. The bucket positioner can store three horizontal settings to facilitate easier attachment changes without resetting the bucket position.
Ground Engaging Tools
Standard replacement and configuration options include cutting edges, teeth systems, and lip systems or shrouds. These components are designed for high-penetration tasks in rock, gravel, or soil applications.

Frequently asked questions
What engine is installed in the WA380-3H?
The machine is equipped with a Komatsu S6D108, a 4-cycle, water-cooled, in-line 6-cylinder, direct injection turbocharged engine.
What is the operating weight of this model?
The operating weight for this specific serial range (H20001-H20500) is approximately 17,420 kg (38,382 lb).
What machine replaced the WA380 series?
The lineage progressed through the WA380-7 and eventually to the modern WA380-8 model.
What WA380-3H(S/N WA380H20051-WA380H20500) owners discuss
What are common hydraulic system concerns for the WA380-3 series during heavy use?
Operators should monitor for rapid oil temperature increases during repeated shuttle work. Potential issues include internal leakage, relief valve bypass, or cooling system restrictions. The machine utilizes a load-sensing system with a variable displacement piston pump to manage flow based on demand.
What transmission and powertrain components should be inspected during a rebuild?
When performing repairs, inspect transmission clutch-related parts, axle seals, and bearings. It is critical to verify the specific torque converter and axle specifications for the machine, as visually similar components may have different dimensions or interfaces depending on the build history.
What are the typical maintenance considerations for the WA380-3 engine and fluids?
Maintenance should include reviewing cooler cleanliness and oil condition. For lubrication, use Komatsu Genuine oils to maintain component durability. Specific requirements vary by configuration; for example, some variants utilize SAE 10W-30 or SAE 15W-40 for the engine oil pan, while hydraulic systems may require SAE 10W.
What electrical or sensor symptoms might indicate a system fault?
Fault symptoms often manifest as dashboard warning lights, such as the L04 red warning lamp, which can indicate SCR system abnormalities. Electronic control systems are sensitive; a single faulty sensor or unstable power supply can trigger multiple warning signals or intermittent starting.
What should be checked when purchasing a used WA380-3H (S/N WA380H20051-WA380H20500)?
Verify the exact torque converter and axle specification against the machine's serial number, as parts can vary with repair history. Inspect for signs of transmission shifting failures or hydraulic system lockups. Check the condition of the bucket, boom, and any installed attachments.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
