Komatsu WA380-6 Wheel Loader Parts Catalog PDF – SN H60051-Up

Description

Komatsu WA380-6 Wheel Loader Parts Catalog – SN H60051-Up

This is the full Komatsu WA380-6 wheel loader parts catalog covering machines from serial number H60051 and up, equipped with the SAA6D107E-6 diesel engine. Instead of guessing at a part number or driving to a dealer counter, you can open this catalog on any device and trace the exact component, its position in the assembly and the correct part number for your machine’s serial range. Every illustration is keyed to item numbers, and every item number maps straight to a part number, description, quantity and the serial-number options that apply.

IMAGES PREVIEW

What makes this catalog genuinely useful rather than just long is the way it is layered. Each assembly is shown as a numbered exploded drawing, then followed by a parts table that carries the item number, the Komatsu part number, the description, the quantity required and — critically — the serial number range where that particular part applies. The WA380-6 changed over its production life, and this document tracks those changes: cylinder head versions, crankshaft and bearing revisions by engine serial number, turbocharger variants, transmission with and without lock-up, main valve spool counts, steering pump generations by pump serial prefix, loader pump generations, and many more. That means when you look up a part you can see not only what fits your machine but which of several possible variants your serial number actually calls for. The catalog also cross-references related parts that are commonly replaced together — gaskets, O-rings, seals, shims, snap rings, bolts and washers — so a rebuild does not stall on a missing seal.

Why This Parts Catalog Matters

Ordering the wrong part on a wheel loader is expensive in a way that goes beyond the price of the part. A mis-ordered hydraulic fitting can mean days of downtime. A gasket that is close but not correct can leak under pressure. A bearing that looks right but has the wrong internal clearance will fail early. This catalog removes that guesswork because it is built around the machine as it was actually assembled, serial range by serial range. Instead of matching by appearance or by a dealer’s memory, you match by the illustration, the item number and the serial range on the page.

What You Can Do With It

• Identify any component on the WA380-6 by system, assembly and item number
• Confirm the correct Komatsu part number for your exact serial number, including mid-production revisions
• Order seals, gaskets, O-rings, shims and fasteners with confidence during a rebuild
• Compare component variants — for example standard versus water-cooled turbocharger, or transmission with and without lock-up
• Work through engine, cooling, fuel, electrical, transmission, hydraulic, frame, cab, guard, wheel and work equipment systems without leaving your workshop
• Quote a repair accurately to a customer because you know exactly which parts are needed and in what quantity
• Keep a machine running through its full service life by understanding what changed across the H60051-up serial band
