WA 180-3 Komatsu WA 180-3 Specifications & Technical Data (1997—2003)

WA180-3 Wheel Loader Walk-Around

Designed for better value through improved reliability and enhanced versatility. That’s why the WA180-3 means value, and anything less is just another Wheel Loader.

Komatsu-integrated design for the best value, reliability, and versatility.

Engine, power train, frame, and all other major components are engineered by Komatsu. You get a machine whose components are designed to work together for higher production, greater reliability, and more versatility.

4-Wheel Drive with Torque Proportioning Differentials

For reduced slippage and longer tire life. This improves the ability of the WA180-3 to maneuver in unstable conditions compared to a similar machine equipped with conventional differentials.

Servicing with a Smile

It would be better if most of us approached routine maintenance and service as something that made us smile. That’s why Komatsu designed the WA180-3 Wheel Loader to make servicing as easy as possible. We know by doing this, routine maintenance and servicing are less likely to be skipped, which can mean a reduction in costly downtime later on. Here are some of the many service features found on the WA180-3: Large service doors provide easy access to the engine compartment. Ground Level Greasing—all grease points are easily reached from ground level and grease banks are provided in some areas to reduce maintenance time. Batteries are located in the counterweight for ground-level access. Sealed Loader Linkage Pins—designed to keep grease contained longer and prevent the entrance of dust, thereby lengthening greasing intervals.

Other features include

Solid state electronic shifting control that reduces wear, increases reliability and provides easy directional shifts. Fingertip shifting from forward to reverse or from one gear to another. Four forward and four reverse gears to better match the cycle conditions. You get higher efficiency and better fuel economy.

Komatsu designed axles and final drives for rugged reliability and low maintenance

Axles are semi-floating, the front axle is fixed. The rear axle is a center-pin support design that provides a total oscillation of up to 24 degrees. The differential reduction gear is a heavy-duty spiral bevel gear for strength and reliable performance. Rugged, inboard planetary final drives carry the total gear reduction of the drive train to the wheel which is mounted to the axle hub.

Wet disc brakes and fully hydraulic braking system

Mean lower maintenance costs and higher reliability. Wet disc brakes are fully sealed. Contaminants are kept out, reducing wear and resulting maintenance. Brakes require no adjustments for wear, meaning even lower maintenance. The new parking brake is also adjustment-free, wet multi-disc for high reliability and long life. Added reliability is designed into the braking system by the use of two independent hydraulic circuits. This provides hydraulic back-up in case one of the circuits fails. Full hydraulic brakes mean no air system to bleed, or the condensation of water in the system that can lead to contamination and corrosion.

New cab for increased operator productivity.

New operator’s cab provides better visibility, increased comfort, see-at-a-glance console, two-door walk through and finger-touch shifting. See pg. 5.

New special rubber-mounted cab for productivity.

Special rubber-mounted cab reduces vibration and noise that can fatigue the operator and reduce his efficiency. See pg. 5.

Consider this valuable feature for added productivity

Kick-down switch automatically downshifts with the touch of a finger from second to first when beginning the digging cycle. Automatically upshifts from first to second when direction control lever is placed in reverse. The result is increased rim pull for better bucket penetration and reduced cycle times for higher productivity.
