Description

Komatsu WA380-6 & SAA6D107E-1D-W Illustrated Parts Catalog

This is the complete illustrated parts catalog for the Komatsu WA380-6 wheel loader and its SAA6D107E-1D-W diesel engine. Every major assembly on the machine and the engine is broken down into exploded-view illustrations with itemised part numbers, descriptions, quantities and kit flags. Whether you are identifying a single seal, sourcing a complete cylinder head assembly, or cross-referencing a serial-number-dependent variant, this catalog gives you the exact part number and the exact quantity required.

The catalog covers machine serial numbers 65001-UP (ecot3, Overseas Version) and engine serial numbers 26500006-UP, with serial-number breakpoints clearly flagged throughout so you order the correct variant for your machine. Engine assemblies also carry the SAA6D107E-1D-W S/N 26500006-UP designation where applicable.

Why This Parts Catalog Matters

Ordering the wrong part for a Komatsu WA380-6 is expensive — both in the cost of the incorrect component and in the downtime while the machine sits idle. This catalog removes the guesswork. Every exploded view shows exactly how components assemble, every part number is printed as Komatsu uses it, and every quantity tells you how many you need. Serial-number breakpoints are flagged so you do not order a pre-26500006 engine part for a later engine, and kit flags identify which items are supplied as part of a larger kit rather than individually. The engine section alone spans hundreds of part numbers across the SAA6D107E-1D-W, from the cylinder head assembly down to individual O-rings, seals, collets and bolts. The machine section covers the WA380-6 from the front frame to the counterweight, including every hose, tube, bracket, clamp, cushion and spacer in the hydraulic, brake and steering systems. For anyone maintaining, repairing or rebuilding a WA380-6, this is the reference that keeps the job moving and the parts order correct.
