Komatsu WA250-5L(S/N A73001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu WA250-5L (S/N A73001-UP) is a mid-size wheel loader in the 135 hp class. This machine features a 6-cylinder SAA6D102E turbocharged engine and utilizes an electronically controlled hydrostatic transmission with 4 forward and 4 reverse gears. Operating at a weight of approximately 25,507.5 lb (11,571 kg), the loader is configured for versatile earthmoving tasks, including loading sand, gravel, and dirt into conveyors or trucks. The series is characterized by its 20.5-2/5 tire configuration and a 30-degree rear axle oscillation capability.
Across the WA250 lineage, advancements have focused on integrating telematics like KOMTRAX for remote monitoring of fuel consumption, load frequency, and fault codes. The transition to Tier 4 engines introduced specific maintenance requirements such as DEF management and KDPF monitoring. In today's used market, this machine remains a high-value asset due to the Komatsu CARE ecosystem, which provides structured service intervals and KOWA fluid analysis. Its availability of genuine parts and documented maintenance schedules makes it a reliable choice for fleet managers looking to minimize long-term ownership costs.

Servicing the WA250-5L(S/N A73001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize Komatsu Oil Wear Analysis (KOWA) at every major service interval to monitor wear metals like iron, copper, and lead. For the SAA6D102E engine, analyze oil for soot, fuel dilution, and oxidation. Regularly check hydraulic fluid particle counts (ISO cleanliness) and coolant pH/SCA concentration levels. These laboratory-grade samples, tracked via KOMTRAX, allow for identifying potential pump or component failures before they cause catastrophic downtime.
Corrective & Common Repairs
Monitor the hydrostatic transmission and hydraulic system for pressure drops; the relief valve setting is 3045.8 psi (2100 bar). If fuel system issues arise, technicians may need to remove the fuel injection pump assembly, requiring careful disconnection of lines and air bleeding post-installation. Regularly inspect hydraulic hoses for cracks or leaks and check articulation/steering pins for excessive play to prevent steering inaccuracies or fluid loss.
Overhaul & Rebuild Points
Major overhaul milestones include the 2,000-hour hydraulic oil change and coolant flush. During high-hour rebuild points, focus on inspecting the turbocharger for play and checking valve adjustments. Evaluate the structural integrity of the boom and bucket linkage welds. For long-term durability, replace worn pins and bushings in the Z-bar linkage and assess the condition of the 24V alternator and 60-amp charging system components.
Seasonal & Environment Servicing
In dusty environments, prioritize frequent air filter element inspections and radiator/oil cooler cleaning to prevent overheating. During cold operations, ensure the cooling system is protected with appropriate antifreeze/coolant concentrations. For machines operating in high-moisture areas, check the fuel/water separator daily and inspect the undercarriage and tire inflation (20.5-25) to maintain stability and traction across varying terrain types.

WA250-5L(S/N A73001-UP) fault codes & troubleshooting
| Code | Meaning | Likely cause | What to do |
|---|---|---|---|
| E03 | Transmission control fault; specifically associated with the swing parking brake system or transmission speed sensor/relay issues causing 4th gear lock. | Transmission speed sensor failure, relay malfunction, wiring harness damage, or internal transmission valve body issues. | Inspect transmission speed sensor and relays; examine wiring harness for damage; check transmission valve body. |
| E10 | Engine controller power failure or engine control drive system circuit malfunction. | Engine stall caused by electrical disruption in the engine management system or power supply failure to the controller. | Check engine controller power supply and inspect engine control drive system circuits. |
| E11 | Engine control system failure. | System malfunction resulting in a reduction of output power to protect the engine. | Inspect engine control system components and check for sensor or circuit faults. |
| E15 | Engine sensor fault. | Malfunction in temperature, fuel pressure, or oil pressure sensors. | Verify integrity of engine temperature, fuel pressure, and oil pressure sensors and their interconnections. |
| CA144 | Coolant temperature sensor feedback voltage fault. | High coolant temperature sensor feedback voltage or low feedback voltage/short circuit. | Inspect coolant temperature sensor and associated wiring for shorts or high resistance. |
| CA234 | Engine overspeed. | Engine RPM exceeding safe operating limits. | Check fuel delivery system and governor/controller settings for improper regulation. |
| CA441 | Battery voltage low error. | Low electrical charge or battery failure. | Check battery voltage levels and alternator charging performance. |
Codes and remedies are general guidance for this model family — always confirm with diagnostic tooling and your dealer before major repairs.

Frequently asked questions
What engine is installed in the WA250-5L?
The machine is powered by a 6-cylinder Komatsu SAA6D102E turbocharged diesel engine, producing 135 hp (100.7 kW) at 2000 rpm.
What is the operating weight of this loader?
The operating weight for the WA250-5L is approximately 11,571 kg (25,507.5 lb).
What model replaced the WA250 series?
The documentation identifies the WA250-6 as a subsequent model in the Komatsu wheel loader lineup.
What WA250-5L(S/N A73001-UP) owners discuss
What are the primary causes of movement failure (machine starts but won't move) in a WA250-5L?
Inspect the hydraulic fluid level and condition first, as contamination or low levels can prevent operation. Check the transmission control valve for blockages or damage, and examine the drive motor and related hoses for leaks or wear. If the parking brake light remains illuminated while attempting to move, investigate the braking system components.
What does an E03 error code indicate on this specific model?
The E03 code indicates a transmission control fault. This is often linked to issues with the transmission speed sensor, a faulty relay, or damage to the wiring harness. In some cases, internal transmission valve body issues can also cause this fault, which may result in the machine being stuck in 4th gear.
What are common engine-related performance concerns for the SAA6D102E series?
While robust, these engines can experience power loss or increased fuel consumption due to airflow restriction, injector wear, or failing fuel delivery components. Frequent injector failure may be linked to contaminated or poorly filtered fuel.
What should be monitored regarding transmission and axle fluid levels?
Operators should check for unexplained fluid loss in the transmission and axles. In some instances, users have reported significant monthly fluid consumption that does not align with visible external leaks; such cases require checking for internal accumulation in the axles, hydraulic tank, or engine.
What are the typical hydraulic system performance specifications?
The system utilizes a gear pump with a flow capacity of approximately 43.1 gal/min (163 lpm). Standard cycle times include a raise time of 6.3 seconds, a dump time of 1.7 seconds, and a lower time of 3.3 seconds, with a relief valve setting of 3045.8 psi.
What is the most critical checklist item when purchasing a used WA250-5L (S/N A73001-UP)?
Verify the exact serial-prefix specification sheet and the installed attachment package. Confirm that any secondary steering systems or specific regional emissions configurations match your operational requirements, as these can significantly alter machine weight, reach, and transport planning.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
