KOMATSU WA500-6 WHEEL LOADER - Repair Manuals Blog

Since its introduction in 1996, the WA500-3 has been updated to meet Tier-2 exhaust gas regulations. During this period, the model’s durability and productivity were well praised. While this was going on, a complete model change was implemented to compete with rival equipment’s increased specifications and meet EU Stage 2 noise regulations, Tier-3 exhaust gas regulatory requirements, which began enforcement in 2006, and other model modifications. WA500-6, a new model of Komatsu wheel loader, was launched to the market at the same time as the WA500-5, a new model of Komatsu wheel loader. The Komatsu WA500-6 Wheel Loader has a high productivity and output, a trademark of Komatsu wheel loaders.

Performance and Economy

High torque, improved low-speed performance, superb throttle response, and modern electronics are all aspects of the new Komatsu SAA6D140E-5 engine for the WA500-6 Wheel Loader. In the end, the outcome is unparalleled production and the lowest possible fuel use. At only 1.900 revolutions per minute (RPM), the engine produces 266 kW (357 HP) and 1.875 Nm of torque at just 1.250 RPM. To provide the greatest durability and dependability, Komatsu built it to the highest standards of engineering and quality (including Komatsu-manufactured electrical components).

As a result of cooled exhaust gas returning to the combustion chamber, NOx emissions are reduced, thermal stress is reduced, and fuel efficiency is increased. Improved engine performance and reduced emissions are achieved by lowering the compressed air temperature from the turbocharger to the cylinders. Combustion timing and ignition have been improved thanks to a brand-new combustion system. Its carefully built combustion chamber minimizes NOx and particle emissions, fuel consumption, and noise levels thanks to rigorous computer simulations and analysis.

KOMATSU WA500-6 WHEEL LOADER Factory Service Manual

The original repair manuals go through every aspect of how the car operates. The Komatsu service manual is an integral tool when fixing or maintaining the machine’s powerful systems.

The service manuals for the KOMATSU WA500-6 WHEEL LOADER are vast and cover every aspect of the vehicle’s operation and diagnostic procedures. The factory-issued KOMATSU WA500-6 WHEEL LOADER service manual was not included with the vehicle but rather was made available to certified mechanics.

Design, Comfort, and Quality

A large-capacity torque converter and an unmatched rimpull-to-weight ratio are two key aspects of the newly built Komatsu power train. Penetrating blasted rock is a piece of cake because of the exceptional rimpull at moderate speeds. Even in tight quarters, V-shaped loading is more productive because of this. Load-and-carry activities benefit greatly from the WA500-6’s acceleration and high travel speeds, even on inclines or steep ramps. The WA500-high-capacity 6’s torque converter and improved engine torque placed it at the top of its class.

Pumps for both hydraulic and steering systems are variable-displacement. Fuel economy soars because of their ability to distribute just the exact quantity of oil needed precisely. Hydraulic control on the bucket, boom, and hydraulically operated attachments are accurate because of Komatsu’s CLSS hydraulics. Load and carry and short-distance transport applications benefit from the new sequential torque lockup mechanism. From second to fourth gear, the operator may activate the mechanism. Because of the increased tractive force, the vehicle travels faster, especially while traveling uphill. At the same time, it reduces fuel consumption by eliminating converter losses.

Hydraulics and Electric Systems

Hydraulic pumps and valves, front and rear axles, engines, transmissions, and torque converters are all products of Komatsu’s engineering and manufacturing expertise and resources. Even the tiniest screw is held to the highest engineering and quality standards. They’re all meticulously engineered to function together seamlessly for optimal effectiveness and dependability.

Thanks to the Komatsu planetary gearbox with electronically regulated automatic shifting, all shifts are perfectly executed. The technology uses the vehicle’s speed, engine speed, and accelerator pedal angle to determine the best shifting point to maintain the engine in an efficient working range and guarantee a smooth gear transfer. Thus, the operator is free to focus on the task at hand while yet achieving optimal productivity.

Heavy Duty Components

The heavy-duty axles, a novel invention, provide an above-average service life even in the most grueling environments. Optional multi-disc, limited-slip differentials are available for the Komatsu WA500-6 Wheel Loader for even more tractive force.

The new SpaceCabTM, the biggest in its class, provides superb driving comfort, on par with that of a passenger vehicle. An unobstructed view of the bucket and tires can be seen via the big frameless glass, providing a good view of the vehicle’s rear. To reduce driver fatigue, the cabin is supported by viscose shock absorbers. Air conditioning (standard) and a fully adjustable, air-cushioned seat with a heater, headrest, and lumbar support improve the driver’s experience. It is possible to work comfortably and efficiently for extended periods thanks to the ergonomic controls on the fully adjustable hydraulic console.
