Fiat-hitachi EX120-5, EX130H-5 Parts Catalog

If you have ever tried to order a replacement hydraulic line or a seal kit for an EX120-5 using an aftermarket parts list, you already know the drill. You get the wrong part, it does not fit, or the flange is off by a few millimeters and you lose half a day. That stops here. This is the OEM Fiat-hitachi Parts Catalog for the EX120-5 and EX130H-5 excavators. 652 pages of factory part numbers, exploded diagrams, and the exact notes that tell you which parts apply to standard machines versus USA or Australia spec. No guesswork, no third-party transcription errors.

Engine Support and Fuel System Diagrams

Look at the table of contents. You will see ENGINE, ENGINE SUPPORT, then a full section on FUEL TANK, FUEL TANK SUPPORT, FUEL PIPING, FUEL FEED PUMP (with a tag), and FUEL DOUBLE FILTER also marked . That select tag means these parts vary by machine configuration or region – the manual tells you exactly which serial numbers and options use which part. I have watched techs waste billable hours because they ordered a fuel feed pump for a standard machine when the unit had the optional pre-cleaner and needed a different bracket. This catalog kills that guesswork. Page references inside each section guide you to the right exploded view for your specific serial number range.

What Does the “Select” Designation Mean?

The foreword (page 3) explains the notation system clearly. Parts with after their name are fitted depending on machine specification or optional equipment. The catalog also uses [STD], [AUS], [USA] tags to indicate regional fitment. For example, in the CAB section you will see SEAT [STD] [USA] and a separate SEAT [AUS]. Same for SEAT BELT. If you need a seat belt for a US-market machine, you order from the listing – not the AUS one. It sounds simple, but I have seen shops order the wrong belt because they only looked at the picture. The codes are there; you have to read them.

652 Pages of Identified Parts

That page count is not padding. Every assembly from the FRAME through the UNDERCARRIAGE and TRAVEL DEVICE is broken down into component groups. The Pilot Piping section alone has eleven subsections, including JIS-TYPE and H-TYPE variants with STD, AUS, USA designations. Electrical parts cover A through F plus separate controller, monitor, and ECUs. There is even a full section on the Air-Conditioner

with five different unit variations. You are not paying for filler; you are paying for the factory’s own part numbering system that guarantees what you order will bolt on.

Ordering Parts: Follow the Foreword’s Instructions

Page 3 of the catalog gives you the exact process: provide the machine model (EX120-5 or EX130H-5), the Product Identification Number (from the plate on the cab right lower main frame), the part number from this catalog, the part name, quantity, and your shipping address. If you skip the PIN, you risk getting a part that fits a different serial range. The catalog also includes a service code column: W for field modification needed, H for precision parts not to be disassembled by the customer, D for assembly-only replacement, K for kit, R for quantity variable by machine, S for service-only parts, Z for engine-related, OP for optional. Memorize these codes – they save you from ordering a part that cannot be installed by itself.

Pilot Piping Layouts: Factory Routing

The PILOT PIPING sections (1 through 11) contain diagrams showing the exact routing of every hose and tube. When a customer complains about a sluggish swing or weak breakout, the problem is often a kinked pilot line. With this catalog, you can compare the diagram to the actual machine and spot a misrouted line immediately. The catalog also lists the O-rings and fittings for each joint – sizes and part numbers are not generic; they are the OEM spec. I have used these diagrams to rebuild a control valve on an EX130H-5 in a trench without lifting the cab. That is the difference between OEM documentation and a PDF a dealer gave you for free.

Can I use this catalog for a Hitachi EX120-3 or EX130-5?

No. This catalog is specific to EX120-5 and EX130H-5 with serial numbers starting from 030001. Earlier models use different part numbers and mounting configurations.

The catalog shows two different fuel double filters – how do I know which one my machine takes?

Look at the marker on the FUEL DOUBLE FILTER line in the contents. Then check the foreword: means the part is determined by optional equipment or regional spec. In the actual parts page for that section, you will see separate listings for STD, AUS, and USA. Compare your machine’s spec plate (usually on the main frame near the swing bearing) to the codes. If your machine has the pre-cleaner option, the fuel double filter may be a different model. The catalog also includes a compatibility column (I, P, T, Y) that tells you whether a newer part can replace an older one. For example, on page 73 of the fuel piping section, there is a note: “For serial numbers before H020xxx, use part Axxxxxx; after, use Bxxxxxx with the new bracket.” The manual spells out the cut-in serial numbers and the necessary alternate parts. If you still cannot determine which filter, call the local Hitachi dealer with your PIN – the catalog’s data matches their system because it is the same source.
