Fiat-hitachi EX100-5, EX100M-5, EX110M-5, EX100-5E Parts Catalog
Every shop that touches an excavator knows the pain of hunting down a part number from a worn-out label or a blurry aftermarket diagram. You waste an hour cross-referencing, still get the wrong seal kit, and the machine sits. This Fiat-hitachi EX100-5, EX100M-5, EX110M-5, EX100-5E Parts Catalog ends that. It is the factory-issued book, 692 pages thick, with the same exploded views and tables the dealer uses. No reprints, no scans from a third party. This is the original reference.
The catalog covers four model variants: EX100-5, EX100M-5, EX110M-5 (North America specific, identical to EX100M-5 per the foreword), and EX100-5E. Each section is marked with tags like <100>,
7 Major Systems Broken Down by Section
The TOC is organized by major assemblies. You get UPPERSTRUCTURE with FRAME, CENTER JOINT, COUNTERWEIGHT. Then ENGINE and ENGINE SUPPORT – critical when you need mounting brackets or gaskets. FUEL system sections include FUEL TANK, FUEL TANK SUPPORT, FUEL PIPING, FUEL FEED PUMP, and FUEL DOUBLE FILTER. If you are replacing a fuel line, you’ll find the exact pipe assembly with part numbers for your region. The catalog also covers PUMP DEVICE, SWING DEVICE, OIL TANK, all the hydraulic piping (suction, delivery, return, drain, main piping in four parts), and the full electrical system with BATTERY, CONTROLLER, MONITOR, ENGINE CONTROL UNIT, and even AM/FM RADIO options.
Page numbers are not just decorative. Need the boom bottom piping for a [USA] machine? You can flip directly to that section – each has its own page range in the printed original. The PDF retains that structure. You get 692 pages of OEM data.
Aftermarket vs. OEM: Why the Factory Book Wins
I have seen aftermarket catalogs that mislabel a part because they combined two different production years into one drawing. The Fiat-hitachi factory catalog distinguishes between standard (STD), USA, EU, and N. EUROPE spec machines. It also notes optional equipment with a
This catalog even includes a part number index at the back – noted in the foreword. If you have a number from the old part, you can look it up directly. For a broader view of how these machine parts tie into the larger Automotive Industry Overview, check that resource. But for this specific excavator, this manual is the only source you need.
Using the Table of Contents to Find Parts Quickly
Open the PDF, and the bookmarks mirror the printed TOC. Start with the major assembly: UPPERSTRUCTURE, LOWERSTRUCTURE (not listed in the excerpt but implied), or the various PIPING groups. For example, if you need pilot hoses for an EX100-5E, look under PILOT PIPING (1) through (11) – each variant has its own sub-section. The designation
Another perspective on documentation standards can be found at Automotive Industry Overview. But that is general knowledge. This catalog is specific.
