Komatsu WA500-1LC(S/N A60001-UP)

Maintenance schedule, common problems & OEM parts breakdown

The Komatsu WA500-1LC (S/N A60001-UP) is a heavy-class wheel loader designed for high-production earthmoving and quarry applications. This series features the S6D140-1 engine and operates within a weight class of approximately 27.5 metric tons (60,627 lb). The machine utilizes a powershift, planetary gear type transmission to manage heavy loads efficiently across various configurations.

Across generations, the WA500 series has evolved from the early -1 series through advanced -8 models, integrating technologies like Komatsu's auto-digging systems and improved emissions controls. Today, this machine remains a staple in the used market due to its robust powertrain and the availability of Komatsu Genuine Lubricants. Its durability makes it a primary candidate for fleet owners prioritizing long-term component life and reliable parts availability.

Servicing the WA500-1LC(S/N A60001-UP) beyond the schedule

Predictive Maintenance & Fluid Analysis

Utilize the KOWA (Komatsu Oil Wear Analysis) program at every major service interval to monitor engine oil, hydraulic fluid, and coolant. Analyze wear metals such as iron, copper, and lead, alongside contaminants like silicon or sodium. Integrating KOMTRAX telematics allows for remote tracking of fuel consumption, fault codes, and DEF levels, enabling proactive adjustments before component failure occurs.

Corrective & Common Repairs

Monitor the hydraulic system for leaks or hose cracks to prevent pressure loss. If brake noise occurs, verify durability; however, frequent service is required for brake pad inspection and measurement. For electrical issues, inspect Deutsch connectors and wiring harnesses for proper seating. Ensure all transmission and axle oil levels are maintained to prevent planetary gear wear.

Overhaul & Rebuild Points

Plan major interventions around the 2,000-hour and 4,000-hour milestones. Key rebuild focus areas include replacing hydraulic hoses, servicing the transmission, and evaluating the pump system. At extended intervals, inspect the turbocharger, swing machinery (for related models), and structural welds. Comprehensive component evaluation is essential for maintaining the integrity of the chassis and drivetrain.

Seasonal & Environment Servicing

In extreme temperatures ranging from -40 to +50 degrees Celsius, prioritize radiator cleaning to prevent overheating. During cold starts, ensure the preheating system is functional. In dusty environments, frequently inspect air filter restriction indicators and clean radiator fins. Always check tire inflation pressure and lug nut torque during seasonal transitions to maintain stability in varying ground conditions.

WA500-1LC(S/N A60001-UP) serial number reference

The PIN plate is located on the front frame, on the right-hand side of the articulation joint. To read the prefix, identify the first three characters of the serial number string; these characters define the machine's model family and configuration. Cross-reference the full serial number with the parts catalog to ensure the correct variant (e.g., WA500-1LC vs WA500-1L) is selected.

PrefixIdentifies
A60001WA500-1LC

Frequently asked questions

What engine is installed in the WA500-1LC?

The machine is mounted with the Komatsu S6D140-1 engine.

What is the operating weight of this loader?

The machine has an approximate weight of 27.5 metric tons (60,627 lb).

What model replaced the WA500-1 series?

The lineage progressed through various iterations including the WA500-3, WA500-6, and the modern WA500-8.

What WA500-1LC(S/N A60001-UP) owners discuss

What are the known hydraulic pump leakage patterns for older WA500 series loaders?
On older models, main and switch pumps may leak into the transmission case. Aluminum-bodied pumps can become loose as they age, which increases pressure on the input shaft seal due to additional leakage.
What engine is used in the Komatsu WA500-1LC (S/N A60001-UP) and what are common failure symptoms?
The WA50/1LC uses a Cummins diesel engine. Reported issues include turbo failure, which can be identified by loss of power or unusual noises; however, some users have successfully repaired these without requiring a full engine replacement.
What are the common electrical and sensor-related symptoms in Komatsu loaders?
Machines may exhibit intermittent starting, dashboard failure, or random shutdowns. Faulty sensors or unstable power supplies can trigger multiple warning signals on the monitor.
How does the hydraulic system configuration differ between older and newer WA500 models regarding pump placement?
Older models typically featured one hydraulic pump on one side and a transmission pump on the other, with a gear-type switch pump mounted to the back of it. Newer configurations, such as the WA500-6, may utilize up to four hydraulic pumps driven by the torque housing transmission (one upper left, one upper right, one under left, and one under right).
What should be checked regarding the transmission and brakes when experiencing movement issues?
If the machine will not move despite a neutral indication on the dash, inspect the neutral safety switch, transmission control solenoids, and wiring. For models with an emergency park brake release, verify the release switch or valve is functional. Note that some users report hydraulic hand brakes on similar loaders can leak into the transmission; have your dealer verify the specific setup for your serial range.
What is the most critical item to check when buying a used Komatsu WA500-1LC (S/N A60001-UP)?
Verify the exact service history and documentation regarding operating hours. Because high-hour machines can suffer from widespread O-ring degradation due to heat, and because low-hour claims require verification, inspect for signs of leaks and confirm the machine has not been subjected to extreme temperature exposure.

Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
