Component and System Documentation

This factory publication delivers the exact structural overviews and technical data required for professional shop-floor service on the WA500-1. It logically breaks the wheel loader down into major operational groups, giving mechanics direct access to critical baseline data. You will find extensive documentation covering the power train, steering, and hydraulics, alongside thorough mapping of the brake, air, and electrical systems. Each chapter details specific testing, adjusting, disassembly, and assembly parameters for major units like the injection pump, radiator, and axles. Working on heavy machinery inherently involves significant physical risks. To support a safe shop environment, the manual provides extensive weight tables for individual components. This ensures technicians can prep the appropriate lifting gear and hoists before starting any major teardown.

Specification Highlights

Having exact technical data on hand directly eliminates guesswork and speeds up shop turnaround. The engine specification tables list the intake valve clearance for the S6D140-1 power plant at precisely 0.43 mm. Need accurate fastener requirements? The torque charts note the standard tightening torque for a 16 mm bolt at 279 Nm. Other essential figures include an 80-liter coolant capacity and a radiator core dissipation capacity of 89.9 cm² for the G7 core type. If your team needs to pull the block, the documentation confirms the bare engine assembly weighs 1,453 kg. These hard OEM numbers allow you to configure your shop cranes and rigging equipment safely, ensuring the machine leaves the bay meeting original Komatsu engineering tolerances.
