Komatsu WA320-3-BO(S/N 50001-UP (FOR BOSNIAN/CHASSIS ONLY))

Maintenance schedule, common problems & OEM parts breakdown

The Komatsu WA320-3-BO (S/N 50001-UP) is a mid-size wheel loader designed for versatile material handling, including loading sand, gravel, and dirt. This specific chassis configuration belongs to the WA320-3 series, featuring a turbocharged engine with a displacement of 8,270 cc (505 cu in). The machine operates within a weight class typically ranging near 16,000 kg (35,000 lb) depending on specific attachments and configurations.

The WA320-3 series represents a refined generation of Komatsu's mid-size loader lineage, following earlier iterations like the WA320-1. In today's used market, this machine remains significant due to its robust powertrain and the availability of Komatsu CARE and KOWA fluid analysis data for well-maintained units. Its durability in heavy-duty cycles makes it a primary target for fleet owners seeking reliable performance without the high entry cost of Tier 4 Final models.

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. For the WA320-3-BO, tracking particle counts in hydraulic oil is critical to prevent pump failure. Use KOMTRAX telematics to remotely monitor fuel consumption, fault codes, and DEF levels to anticipate component fatigue.

Corrective & Common Repairs

Monitor the hydraulic system for clarity; cloudy fluid indicates water or air contamination. Inspect the transmission for clutch-related issues during gear transitions. Check the turbocharger and intake manifold sensors if engine performance drops. For this chassis, ensure all pins and bushings are inspected for excessive play. If cracks appear in structural components, evaluate if the depth exceeds one-third of the part thickness before deciding to repair or replace.

Overhaul & Rebuild Points

Plan major interventions around the 2,000-hour and 4,500-hour milestones. Key rebuild points include hydraulic oil changes, transmission service, and coolant flushes. At approximately 4,500 hours, prepare for a Komatsu Diesel Particulate Filter (KDPF) exchange. Evaluate the torque converter and transmission clutches during heavy-duty overhaul cycles to maintain the machine's high breakout force and operational efficiency.

Seasonal & Environment Servicing

In dusty environments, increase frequency of air filter inspections and radiator fin cleaning to prevent overheating. During cold operations, ensure engine oil viscosity is appropriate for ambient temperatures; while SAE 10W-30 is standard, single-grade oils may be required for extreme cold. Always check the battery load test and terminal corrosion before seasonal transitions to ensure reliable starting in low temperatures.

Frequently asked questions

What engine is installed in this model?

The WA320-3-BO features a 4-cycle, water-cooled, in-line, 6-cylinder turbocharged engine with a displacement of 8,270 cc (505 cu in). Depending on the specific serial range within the 50001-UP bracket, it may utilize the Cummins 6CT8.3 or the Komatsu S6D114E-1/419 engine.

What is the operating weight of the machine?

The operating weight varies by configuration and attachments, but related WA320 series models typically operate in the range of approximately 13,590 kg (29,960 lb) to 16,000 kg (35,000 lb).

What model replaced the WA320-3?

The WA320-3 was succeeded by later generations of the WA320 series, including the more advanced WA320-6 and the Tier 4 Final compliant WA320-8.

What WA320-3-BO(S/N 50001-UP (FOR BOSNIAN/CHASSIS ONLY)) owners discuss

What are common transmission behaviors and issues reported for the WA320-3 series?
Operators have reported significant deceleration and hard bouncing during downshifts, specifically when transitioning from 3rd to 2nd gear. Some units experience intermittent gear engagement or slipping under load. In certain configurations, the machine may fail to move in forward or reverse despite adequate fluid levels. For issues involving reverse gear delays, check for solenoid sticking or broken springs within the valve body. If both forward and reverse solenoids show identical voltage during testing, swap them to identify a faulty unit. Have your dealer verify.
What are the known hydraulic and pump-related symptoms in this machine type?
A common symptom is cavitation noise originating from the pump at any RPM above idle. Additionally, transmission overheating or failure to move under load can be linked to air entering the system; inspect suction piping for loose clamps or leaks. If hydraulic oil appears cloudy, it may indicate water or air contamination in the circuit.
What electrical or sensor issues are frequently documented?
Common electronic issues include intermittent failure of water and transmission gauges. Users have reported 'engine secondary switch' warnings that persist on the display even after the engine is turned off. For specific fault codes like E03, these typically indicate a pressure sensor malfunction. When troubleshooting wiring, resistance between specified harness connectors (such as L41 and T11) and chassis ground should be 1MΩ or higher.
What are the typical brake system failure modes for the WA320?
The machine may experience sudden stops or brake lockup. This behavior is often traced to a faulty hydraulic accumulator, which stores pressure to release the brakes, or related wiring issues.
What engine models and specifications are associated with this serial range?
For the WA320-3 (S/N H20001 - H20560), the engine is a Cummins 6CT8.3, which is a 4-cycle, water-cooled, in-line, 6-cylinder, direct injection turbocharged engine with a displacement of 8,270 cc (bore x stroke: 114 x 135 mm). For the WA320-3 (S/N 20561 and up), the engine is a Komatsu S6D114E-1 / 419. Both configurations utilize a 24 V starting motor (7.5 kW) and a 24 V, 50 A alternator.
What should be checked when purchasing a used WA320-3-BO (S/N 50001-UP)?
Inspect the shifter linkage for looseness or 'floppy' movement, as worn shift forks can cause gear engagement problems. Check the hydraulic accumulator pressure and inspect all suction piping for leaks to prevent pump cavitation. Verify the condition of the engine oil and ensure it meets API classification standards; if using API CC oil, reduce change intervals by half. Finally, check for any active fault codes in the system memory via the instrument cluster or diagnostic software.

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