Fiat-hitachi EX100-5, EX100M-5, EX110M-5, EX100-5E Parts Catalog

If you’re wrenching on any of those four models—Fiat-hitachi EX100-5, EX100M-5, EX110M-5, EX100-5E—and you don’t have a factory parts catalog in your toolbox, you’re guessing. I’ve seen guys order a main control valve assembly because they couldn’t tell which spool was which. That’s a $2,000 mistake. This is a 190-page Parts Catalog printed from the original OEM file. It’s not a reprint. Not a scan. It’s the same document the dealer parts counter uses.

PUMP DEVICE: How the System Breaks Down

The first major section in the catalog covers the pump assembly. You get exploded views of the pump device, the pump unit, the regulator, and the gear pump. There’s even a separate subsection for the blade pump device. Each part has its own number, description, and quantity per machine. If you need the regulator piston kit for an EX100-5E, you’ll find it here without flipping through three different aftermarket books that don’t match.

MOTOR; OIL – Swing, Travel, and the Brake Valve

Page references aside, the motor section is broken into swing motor and travel motor groups. The swing motor includes the rotary group, shaft part, cover part, and two critical valves: the relief valve and the timer valve. For the travel motor on the EX100-5 and EX100-5E, you get a dedicated brake valve (listed as VALVE ; BRAKE) plus its own relief valves. The EX100M-5 and EX110M-5 have a separate travel device subsection. If the tracks won’t hold on a slope and you suspect the brake valve, this catalog gives you the part number—not a guess.

VALVE Section: Control, Pilot, Solenoid – 10 Sub-Sections

The valve chapter alone takes up a third of the book. You get the main control valve broken into ten separate sub-sections (VALVE ; CONTROL 1/10 through 10/10), plus pilot valves for front & swing, travel, and FC valves. There are also solenoid valves, lock valves, shuttle valves, rotary valves, a holding valve, and a hose-rupture valve. Each sub-section has its own exploded diagram. If you’re rebuilding a control valve stack because of internal leakage, you can ID every spool, spring, and O-ring by the OEM part number listed.

3 Sections You’ll Use Most: Cylinder, Parts Index, and Foreword

The cylinder section covers boom cylinders (right and left, including offset boom variants), arm cylinder, bucket cylinder, clamshell, offset, and blade cylinders. Each cylinder has its own parts breakdown. The parts index at the back gives you a part-number cross-reference so you can look up an old number and find the superseded replacement. The foreword explains how to read the catalog, including service codes like W (field modification needed), D (replace as assembly), and OP (optional part). Don’t skip that page—it’ll save you an hour of confusion.

Does This Catalog Cover the EX110M-5?

Yes. As noted in the foreword, the EX110M-5 is the North American designation for the EX100M-5. They are identical. The catalog includes both model numbers in the title and in every section that applies. The travel device section specifically lists <100M-5, 110M-5> in the subtitle.

Source Validity: OEM vs. Third-Party Catalogs

Aftermarket parts catalogs are notorious for truncated diagrams and wrong quantities. I’ve seen a third-party catalog list the wrong number of shims for a valve stack, or miss the lock valve entirely. This is a direct OEM PDF from the AutoRepairManuals collection—scanned from the factory print. You get the same numbering system Hitachi engineers used. The Automotive Industry Overview doesn’t apply here, but the same principle holds: trust the original spec, not a copy.

Does this catalog include the EX110M-5?

Yes. The EX110M-5 is the North American badge for the EX100M-5. Both are covered.

What if I need a part not listed in the exploded view?

Check the Parts Index at the back. It lists every part number in alphanumeric order. If the part is a sub-assembly like the control valve (10 sheets), you have to reference the correct sheet. Service codes like “K” (part of a service kit) are noted. For optional parts, look for the “OP” flag.

Are torque specs included?

No. This is a parts catalog, not a service manual. It gives part numbers, quantities, and exploded views. For torque values, you need the factory service manual. Automotive Industry Overview doesn’t help either.

Can I order parts directly from this catalog?

Yes. Use the part number, quantity, and model serial number (P.I.N. on the main frame nameplate) when contacting your Fiat-hitachi dealer. The foreword explains the exact ordering procedure.

If you’re tired of ordering wrong seals and mismatched valve assemblies, Access the Factory Manual and get back to putting the machine together the right way. I keep a copy on my tablet in the shop—saves me a phone call to the dealer every time a part number is worn off.
