Fiat-hitachi EX200, EX200LC Parts Catalog – 192 Pages of OEM Part Numbers

If you’re ordering replacement parts for an Fiat-hitachi EX200 or EX200LC without the factory parts catalog, you’re gambling with your budget and downtime. I’ve seen guys slap a seal kit from a generic supplier into a main control valve, only to find the O-ring ID was wrong by 0.5 mm. That leak costs you a day and a half. This manual—the Fiat-hitachi EX200, EX200LC Parts Catalog—gives you the exact part numbers, service codes, and interchangeability notes straight from Hitachi’s engineering. 192 pages, no aftermarket guessing.

PUMP Section – Matching Part Numbers to Your Serial Number

The pump assembly on an EX200 has over 40 individual components listed in this catalog. Each one carries a Hitachi part number, a quantity per pump group, and a service code (W, D, K, R, S, OP, OS, US). For example, if you need a piston shoe, you look up the pump section, find the reference number, then verify your machine serial number against the “適用号機” column. Page 1 of the OCR excerpt shows the format: part number P145-E1-7, serial number range 30001~. That level of specificity keeps you from ordering a pump cartridge that won’t fit your machine’s build date. The catalog also flags superseded parts with interchangeability codes (I, P, T, Y) so you know if a newer part can replace an older one or if the old part is prohibited. After working on these machines for years, I can tell you that ignoring the serial number match is the fastest way to stack up returns.

VALVE and CYLINDER Sections – Why Seal Kits Fail Without OEM Data

The valve section covers the main control valve, swing valve, and any auxiliary hydraulic valves. Each spool, spring, plug, and seal is listed with its own part number. The cylinder section does the same for boom, arm, and bucket cylinders. When you order an aftermarket seal kit, you’re betting the supplier matched the cross-section and durometer correctly. The factory catalog gives you the OEM part number for each seal, plus an OS (oversize) or US (undersize) suffix if the cylinder has been reworked. I’ve seen techs install standard-size piston seals in a cylinder that had been honed to OS spec—the seal blew out in 10 hours. Use the valve and cylinder sections to verify the exact seal dimensions before you order. The Automotive Industry Overview shows how precision parts manufacturing standards apply here too, but this manual keeps it specific to your machine.

Using the Parts Index to Avoid Ordering Wrong Components

Toward the back of this catalog—the parts index—lists every part number in numerical order. If you have a part number from an old tag or a worn-out component, you cross-reference it here. The index tells you which section (pump, motor, valve, cylinder) that part belongs to. Then you flip to that section, find the exploded diagram, and confirm the quantity and any service restrictions. For example, a port relief valve cartridge might appear in both the pump and the main control valve sections. The index eliminates that confusion. This is the advantage of an OEM parts catalog printed by Hitachi—it’s organized the way the factory builds the machine, not the way a third-party reprint decides to group things. The related manual HITACHI EX200 EX200LC Hydraulic Excavator Parts Catalog covers the same machines, but this version includes the full equipment components parts list as originally issued.

OEM Documentation vs Aftermarket Part Listings

Aftermarket parts catalogs are usually compiled from generic cross-reference databases. They might show a “will fit EX200” without accounting for serial number splits or design changes that happened during production. The OEM manual—this one—came from Hitachi’s service engineering group. Every part number was validated against the actual components used on the assembly line. The “互換性” (interchangeability) column tracks when a part was superseded, and the “適用号機” column ties each part to a specific machine serial number. If you’re ordering for an EX200LC with serial number 145-31000, you need to check whether the pump you’re buying was used from 30001 to 34999 or only from 35000 onward. That split is documented here. Aftermarket listings don’t carry that data. Fiat-hitachi EX200 Workshop Manual – 392-Page OEM Factory Manual gives you repair procedures, but this catalog is strictly for parts identification—they complement each other. For the technical specs behind each component, the Fiat-hitachi EX200 Technical Manual – Factory OEM Specs provides hydraulic flow rates, pressure settings, and tolerances.

192 Pages of Factory Specified Parts – What That Means on Your Bench

When you open this catalog, you’re holding the same document Hitachi dealership parts counter used in the 1990s. 192 pages, stapled and bound with a fold-out cover. The foreword (page 5 of the original) states that the list contains “the most recent information available at the time of printing.” That means if you’re working on an early serial number machine, the part specified might not be the same as one built two years later. The catalog flags those differences with serial number ranges and interchangeability codes. You can order a swing motor seal kit, cross-check the part number against your machine’s serial number, and know with certainty that the O-rings and backup rings will seat correctly. The Automotive Industry Overview explains the broader context of manufacturing standardization, but here, the application is specific and immediate.

Frequently Asked Questions

Can I use this Parts Catalog to repair the machine?

No. This is a parts identification manual, not a repair procedure guide. Use it to order components. Pair it with the workshop manual for removal and installation steps.

Does it cover both EX200 and EX200LC?

Yes. The catalog explicitly lists parts for both models. The cover says “EX200 EX200LC,” and the contents show the same part numbers applied to both, with separate serial number columns where components differ. The EX200LC typically includes longer undercarriage and heavier counterweight; the catalog accounts for that. If you need a track adjuster seal, you’ll find a single part number that applies to both unless the LC uses a different adjuster assembly—then it’s listed separately with its own serial number range. Always check the “適用号機” column for your specific machine’s serial number before ordering. That extra step saves you from buying a part that belongs to the standard track frame when you have the LC frame.
