Fiat-hitachi EX225USR, EX225USRLO, EX225USRIKE, EX225USREICH Parts Catalog

If you are hunting for a worn seal on the pump device and the aftermarket diagram shows the wrong part number, you are losing billable hours. I have seen it. That is why you need the actual Fiat-hitachi EX225USR, EX225USRLO, EX225USRIKE, EX225USREICH Parts Catalog – 658 pages of factory part numbers, not guesswork. This is the same binder the dealer parts counter uses. No third-party reprint, no translation errors. The OCR excerpt from page 5 shows the foreword explaining model suffixes: <225>, , . That matters when you order a center joint or a pilot valve.

Engine and Fuel System Coverage

You need to tear down the upperstructure for a fuel leak? The manual gives you separate sections for Engine, Engine Support, Fuel Tank (55L and 80L), Fuel Tank Support, and Fuel Piping. Each section has its own illustration with callout numbers and the corresponding part numbers. The Fuel Piping section alone covers lines from tank to pump. If you skip the support bracket diagram, you will bolt the tank to the wrong frame holes. I have watched a green tech do that. Cost him half a day.

658 Pages of Verified Part Numbers

Every page number in this catalog corresponds to a real assembly drawing. Need the swing device support? Flip to that section. The manual lists everything: pump device (with and without blade), swing device, oil tank, delivery piping, return piping, drain piping. There are 13 separate pilot piping sections – 5-1 through 5-3 with blade and without blade variants, plus JIS and H-type fittings. That is the level of detail you need when a hose rubs through and you have to match the exact banjo fitting. The parts bookmarks in the PDF let you jump directly to Main Piping (1) through (4) or the Blade piping.

Does It Cover the EX225USRIKE and EX225USREICH Models?

Yes. The series includes EX225USR, EX225USRLO, EX225USRIKE, and EX225USREICH. The foreword (page 5) explains the marking system: <225> for EX225USR and EX225USRLO, for EX225USRIKE and EX225USREICH. Also uses [STD], [EU], [N. EUROPE], [AUS] for regional specs. If you have a European-spec machine, you use the pilot piping section marked [EU]. Ignoring those brackets means ordering the wrong control valve support. The manual clearly separates them.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs often combine multiple model years into one generic drawing. That gets you a part that sort of fits but not exactly. This is an original Fiat-hitachi PDF published for their excavator series. The part numbers are the same numbers stamped on the original castings. When you call the dealer, you read them the number from page whatever – they pull the box from the shelf. No cross-referencing. No return shipping. This manual also includes the memo pages (page 3) for recording machine serial numbers and engine numbers. That is a small thing that saves you when you need to order a second time. Related manuals you may need: Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog, Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs, Fiat-hitachi ZX500LC, ZX500LCH Parts Catalog – 464 Pages.

Pilot Piping: 13 Sections of Exact Routing

The pilot piping section is the worst place to guess. One wrong o-ring and you lose pilot pressure to the control valve. This catalog breaks it into 5-1, 5-2, 5-3 with and without blade, then sections 6 through 13 for specific regional fitting types. For example, Pilot Piping (8) has JIS type [STD] and H-type [STD]; also [EU] and [N. EUROPE] variants. That level of granularity is what keeps your travel pedal from feeling mushy. Do not assume all pilot lines are the same across models. They are not.

Use the Foreword to Understand Model Variants

Page 5 of the PDF is worth reading twice. It explains how to read the catalog: part numbers, callout symbols, and the suffix system. It also tells you that engine parts are in a separate Isuzu A-6BG1-T parts catalog. That prevents you from searching for pistons in this book. The foreword also specifies orientation – boom side is front, engine side is rear. That matters when you are ordering a boom foot pin assembly or a center joint. Get the orientation wrong and you bolt the upperstructure on backward. I have seen it.

FAQ

Can I order parts for an EX225USRLO using just this catalog?

Yes. The EX225USRLO is explicitly listed on page 1 and throughout the manual. Use the <225> suffix.

Why are there separate fuel tank sections for 55L and 80L, and how do I choose?

The notation

means that tank is optional depending on your machine’s specification. The 55L tank and 80L tank use different supports, fuel piping, and even different pump device configurations. If your machine serial number falls within the range that uses the larger tank, you must order the 80L unit. Check the machine PIN against the application table inside the manual – the parts catalog does not list the serial number cutoffs, but the foreword references that. If you are rebuilding a machine that was originally 55L, do not swap to 80L without also ordering the support bracket and main piping (1) which may differ. The manual’s Fuel Tank Support and Fuel Piping sections will show you exactly which parts change.
