Komatsu WH609-1, WH613-1 Parts Catalog – 347 Pages OEM Indexing

Description

You’ve got a Komatsu WH609-1 or WH613-1 telescopic handler in the shop with a blown hydraulic line or a broken control cable. You look up the part number on some generic site, order it, wait three days, and it’s the wrong fit. That’s why you need the genuine factory Komatsu WH609-1, WH613-1 Parts Catalog. This is the same document the dealer parts counter uses — 347 pages of exploded diagrams, OEM part numbers, and assembly breakdowns that tell you exactly what you need, not what some third-party guesser thinks you need.

Parts Breakdown for the Komatsu S4D104E-1 Engine

The engine section covers the Komatsu S4D104E-1 diesel, the same powerplant used across multiple Komatsu Utility machines. You get individual callouts for pistons, rings, cylinder heads, injection pump components, and gaskets. Each part is linked to a figure number so you can cross-reference the diagram. The catalog includes the transmission as well — a Clark unit — with separate breakdowns for the torque converter and valve body. No more digging through aftermarket websites hoping for a match.

What Do the Symbols on Page 4 Mean?

Flip to page 4 and you’ll see a legend that saves hours of confusion. Symbols like ★ (supplied only as a kit if requested), ◎ (assembly not sold individually), and the interchangeability markers (▲, ▼) are all spelled out. The manual uses Italian terms but the icons are universal. Once you learn that the dotted line means “these parts are components of the assembly listed below,” you stop ordering duplicates. That page alone keeps your parts bin clean.

3 Reasons You Need This Parts Catalog

First, every part number is tied to a specific serial number range — WH609-1 395F60001 and up, WH613-1 395F60003 and up. Second, the exploded views show fastener locations and torque sequence hints (though torque specs belong in the shop manual). Third, the kit listings (marked with +) tell you when a group of parts must be ordered together. You cannot get this accuracy from a generic aftermarket PDF. If you want repair procedures, grab the Komatsu WH609-1 WH613-1 WH713-1 WH714-1 WH714H-1 Shop Manual to pair with this parts book. For overhaul instructions, the Komatsu WH609-1 WH613-1 WH713-1 WH714-1 Workshop Manual covers disassembly and assembly. And the KOMATSU TELESCOPIC HANDLER Operation & Maintenance Manual handles daily operation and fluid specs.

Get the Right Part Numbers the First Time

Ordering parts from memory or a photo is a gamble. This catalog eliminates that. Each figure number is laid out with a table: figure number, description, quantity, and part number. The column marked “Notificia” alerts you to superseded parts or discontinued items with replacements. The Δ symbol next to a part number means the replacement must be modified before installation. That kind of detail keeps your technician from cramming a wrong-sized seal into a bore and causing a leak. The Automotive Industry Overview shows how OEM documentation reduces warranty claims — this catalog is the first step.

Engine Section: Komatsu S4D104E-1

Dive into the engine section and you’ll find everything from the oil pan up to the turbocharger. Each component has a group number (e.g., G1, G2) indicating how many assemblies are required. The paint codes (PAINT (1), PAINT (2)) tell you if the part comes pre-painted or in a specific color. For cold-weather operation, parts marked (A) are rated to -30°C; hot-climate parts (B) to -50°C. The internal combustion engine basics are universal, but the Internal Combustion Engine article won’t help you find the right piston ring set — this catalog will.

Audience Fit: Who Needs This Catalog

If you own a WH609-1 or WH613-1 telescopic handler and do your own repairs, this catalog is your parts reference. Beginners can use the exploded views to identify components before calling a dealer. Experienced mechanics use it to verify part numbers when rebuilding pumps or cylinders. The 347 pages cover every bolt, clip, and hose. You don’t need to be fluent in Italian — the diagrams are numbered and the symbols are standard across Komatsu Utility equipment.

Source Validity: OEM vs. Aftermarket

This is a direct scan of the factory Komatsu parts book — WEPB006901. The paper original was printed for dealer use. Aftermarket parts catalogs often omit supersession notes and skip kit-only parts. This manual includes both. The serial number breakout is printed on page 1: WH609-1 395F60001 and up, WH613-1 395F60003 and up. If your machine falls outside those ranges, cross-check with a newer supplement. No aftermarket PDF can match the accuracy of original OEM data. When you access this, you get the exact same document a Komatsu dealer uses to order parts for your machine.

Does this catalog include the WH713-1 or WH714-1?

No. This catalog covers only the WH609-1 and WH613-1 models.

How do I use the symbol key to avoid ordering the wrong part?

Start on page 4. Read the symbol descriptions carefully. The ★ means the part is supplied only in a kit if you request it — you cannot order that part individually. The ◎ means the item is an assembly and not available separately; you must order the whole group. The dotted underline indicates the parts below that line are components of the assembly listed directly above. When a part is superseded, the Δ symbol appears and the replacement number is listed. Pay attention to the “Notificia” column — it tells you when a part is no longer available and what to use instead. Ignoring that column is how you end up with a box of wrong gaskets.

Your time is money. Every wrong part that shows up costs you shipping, restocking, and downtime. Get the factory 347-page parts catalog on your workbench now. Access the Factory Manual and start ordering the right parts today.
