Komatsu WA600-3 and WA700-3 With AJSS specifications

History and service record of WA600-3 and WA700-3 With AJSS

• Emissions compliance of the WA600-3. A Japanese construction-equipment museum's entry on the WA600-3 of 1998 says the WA600 was also built to be more environmentally friendly, passing the emission regulations in Europe and the United States.

• Loading a crusher. A Heavy Equipment Forums poster described seeing a WA600 loading a crusher with blasted limestone, apparently in a demonstration where a couple of different loaders were tried out. Komatsu WA600, Heavy Equipment Forums.
• Reach against big trucks. In the same thread one poster who had worked around Cat 777 85-ton trucks loaded by 992 wheel loaders said a WA600 could not even reach the middle of one of those trucks, while another said a newer-style WA600 at his work will nearly reach across an EH1000 body.

• Hydraulic pump parts. A mechanic's thread on a wheel loader hydraulic pump describes an owner whose Komatsu WA600 would neither raise the boom nor steer; the owner had bought a bin of WA600 parts at auction that included a transmission and a switch pump, and the pump on the machine did not look exactly like the spare.

• Engine service interval doubled. Komatsu's WA600-3 and WA700-3 brochures say the Stage II SAA6D170E-3 engine brought engine oil and filter change intervals out from 250 hours to 500 hours. WA700-3 wheel loader, Komatsu Europe.
• Joystick steering option. The WA700-3 can be delivered with a standard steering wheel or with the optional Advanced Joystick Steering System (AJSS), which Komatsu positions for precise control in V-type loading. WA700-3 wheel loader, Komatsu Europe.
• Cab on viscous mounts. Both loaders use a cab damper mounting with silicone-oil-filled rubber mounts to cut vibration at the seat, and the service and parking brakes are fully hydraulic wet-disc units. WA700-3 wheel loader, Komatsu Europe.
• WA600-3 figures. Komatsu's WA600-3 brochure lists 357 kW (478 hp), 46,165 to 49,400 kg and a 5.6 to 7.5 m3 bucket. WA600-3 wheel loader, Komatsu Europe.
• Ground-level service. Large doors lock with the cab key, the rear fuel tank allows ground-level fuelling, and greasing points are grouped in centralised service banks at ground level. WA600-3 wheel loader, Komatsu Europe.
• WA700-3 figures. Komatsu's WA700-3 brochure lists 502 kW (672 hp), 72,080 kg and an 8.0 to 9.4 m3 bucket. WA700-3 wheel loader, Komatsu Europe.
