Komatsu WA500-6 Parts Catalog 55001-UP Wheel Loader Illustrated Parts Manual PDF

Description

Komatsu WA500-6 Parts Catalog — SN 55001-UP (ecot3, North America)

This is the complete illustrated parts catalog for the Komatsu WA500-6 wheel loader built for the North American market with the ecot3 emission configuration. It covers every machine from serial number 55001 and up. Every assembly in the machine is broken down into exploded diagrams with item-number callouts linked to genuine Komatsu part numbers, descriptions, and quantities — the exact reference a parts counter, workshop, or owner needs to identify and order the right component the first time.

Between the chapter breakdown above, the tables of part numbers, and the hundreds of exploded illustrations, this catalog gives a technician a complete visual map of the WA500-6. Every assembly — from the engine mounts through the last bolt on the counterweight — is drawn apart and numbered, so you can identify a component by sight and order it by part number without guessing.

What This Catalog Lets You Do

When a machine needs a hose, a seal, a bearing, a cylinder, a control valve, a sensor, or a structural plate, the exploded view shows exactly which piece sits where and which part number identifies it. There is no ambiguity about left or right, no confusion between the numerous tire and rim configurations, and no risk of ordering a transmission component that belongs to the standard build when your machine is the lock-up version.

The catalog also resolves the details that catch people out: the difference between the standard and quick-coupler fuel tank plumbing, between the 2-spool and 3-spool hydraulic valve layouts, between the standard lift and high-lift boom, and between the countless bucket edge, tooth, and cutting-edge combinations. Every one of those is drawn separately and part-numbered separately.

Why It Matters

Ordering the wrong part on a machine of this size is expensive and slow. A correct illustrated parts catalog removes that risk. It also gives the workshop a way to plan a repair properly — see which seals, O-rings, and bearings sit behind the component being replaced, and have them on the bench before the job starts. For anyone keeping a WA500-6 running in a production environment, that saves downtime.
