Komatsu WA470-3M Active+ to WA480-5 specifications

History and service record of WA470-3M Active+ to WA480-5

• Hydraulic overheating report. A Heavy Equipment Forums poster reported that both WA470s at his work were overheating the hydraulic oil because the steering pressure was not returning to unload pressure. WA470-7 Komatsu overheating hydraulic oil, Heavy Equipment Forums.
• Two-stage hydraulics on the -5 loaders. Komatsu's WA470-5 brochure describes a two-stage hydraulic system in which the main and switch pumps send flow to the tyres while digging and to the work equipment when the boom rises, plus a selector that changes between two hydraulic speed modes.

• Transmission modes and lockup. The transmission selector on the WA470-5 switches between manual shifting and three automatic modes (high, medium, low), and an option adds torque-converter lockup in third and fourth gear to cut fuel use on load-and-carry work.

• Semi-automatic dig. Komatsu calls its patented semi-automatic bucket filling new to the world: a pre-programmed fill cycle runs through the electrical pilot control, so the operator no longer works the bucket lever when driving into the pile. WA470-5 wheel loader brochure, Komatsu.
• Dump height and stance. With a 4.1 m3 universal bucket the WA470-5 dumps at 3,100 mm with 1,295 mm of reach, and it has a 2,230 mm tread, a 3,450 mm wheelbase and 40-degree steering angles. WA470-5 wheel loader brochure, Komatsu.
• Service interval display. The monitor keeps an error memory and a service-interval display that tells the operator when oil and filter changes are due, and the oil cooler and charge-air cooler swing out for cleaning. WA470-5 wheel loader brochure, Komatsu.
• WA480-5 figures. The WA480-5 is listed at 215 kW (288 hp) net at 2,000 rpm, a 224 kW peak at 1,760 rpm, 1,390 Nm at 1,400 rpm, up to 25,700 kg and a 4.2 to 6.2 m3 bucket, with a 3,240 mm dump height and 1,350 mm reach on a 4.5 m3 bucket. WA480-5 wheel loader, Komatsu Europe.
• Komtrax on the -5 loaders. Komatsu's Komtrax option on the WA470-5 uses an electronic control unit, a GPS transmitter and a satellite antenna to report machine location and real-time service hour meter readings over an internet connection. WA470-5 wheel loader brochure, Komatsu.
• Frame, axles and limited slip. The WA470-5 frame has hinge points far apart to cut bearing stress in torsion, uses heavy-duty axles, offers multiple-disc limited slip differentials as an option, and its engine, transmission, torque converter and axles are all original Komatsu components. WA470-5 wheel loader brochure, Komatsu.
• O-rings and plugs. All hydraulic connections use Komatsu O-ring seals, the cylinders have guide rings to support the rods, and the wiring uses dust- and water-proof DT plug-and-socket connectors. WA470-5 wheel loader brochure, Komatsu.
• Gull-wing service doors. The service doors are gull-wing type, the radiator fan can be reversed from the cabin for dusty work, and the oil cooler and charge air cooler swing out for cleaning. WA470-5 wheel loader brochure, Komatsu.
