Fiat-hitachi EX220, EX220LC Parts Catalog

If you’re tracking down a valve for an EX220 or EX220LC, the aftermarket catalogs will waste your time. I’ve seen it. You get a part number that doesn’t match, or the diagram skips the brake relief valve you need. That’s why this Fiat-hitachi EX220, EX220LC Parts Catalog from the factory matters. It’s 244 pages of exploded views and part numbers indexed exactly how Hitachi laid them out. No reprints, no photocopies – this is the same document the dealer uses.

Pump and Regulator Breakdown – What You’ll Find in the Catalog

The PUMP section breaks into four single-pump assemblies and a gear pump, with the regulator drawn separately. You get the exact part numbers for each piston, swashplate, and seal. No guessing which O-ring fits the charge pump – the catalog lists it with the regulator assembly. The page layout mirrors the factory build sheet, so if you’re ordering a replacement pump core, you can hand the parts guy the right number without flipping through a generic cross-reference.

Motor and Brake Valve Assemblies – Swing and Travel

Under MOTOR;OIL, you’ll find swing motor and travel motor breakdowns. Each travel motor section includes a Valve ; Brake and Valve ; Relief – three times in the TOC, so you know the brake valve is a wear item. If the machine creeps on a slope, that brake valve is the first suspect. The catalog shows the relief valve cartridge and the brake piston as separate line items. You can order the exact relief spring instead of buying the whole motor housing.

Control Valve Sections – 4-Part Exploded Views

The VALVE chapter runs over a dozen entries. The control valve splits into four multi-page views (1/4 through 4/4). Each page lays out spools, springs, and plugs with Hitachi’s own screw and dowel pin part numbers. Pilot valves, solenoid valves, check valves, shockless valves, lock valves, relief valves, and hose rupture valves each get their own spread. When a pilot line leaks, you trace back to the VALVE ; PILOT illustration and grab the correct seal kit number. That’s the difference between ordering the right part and eating the return shipping.

Cylinder Group – Boom, Arm, Bucket with Service Parts

Five boom cylinder variants (right and left, including service parts marked ), four arm cylinder entries, and five bucket cylinder entries. Each cylinder assembly shows the rod, piston, gland, and seals. The service part indicator tells you which components Hitachi sells individually for overhauls rather than as a complete cylinder. If you’re rebuilding a boom cylinder, you pull the page for CYL. ; BOOM (R) and order the rod seal and wiper separately – cheaper than a full assembly.

Who Needs This Catalog – And Who Doesn’t

Owner-operators who wrench their own EX220 or EX220LC will use this daily. If you’ve got a track machine and you’re tired of paying dealer markup for a brake valve or a travel motor seal, this catalog pays for itself on the first order. Professional shops that handle multiple excavator brands will also want it – the OEM part numbers and interchange codes (I, P, T, Y) save you from cross-referencing aftermarket sources that get it wrong. Beginners? Stick to the service manual first. This catalog assumes you know how to disassemble the pump; it only tells you what to order.

Why Factory Parts Catalogs Beat Aftermarket Every Time

The source data here is Hitachi’s own print – not a third-party repackaging. The foreword states the numerical parts index is from the factory, and the Japanese and English text confirms it’s the same document Hitachi ships with the machine. Aftermarket catalogs often skip the service codes (W, D, K, R, S, OP) that tell you if a part needs local machining (W), must be ordered as a kit (K), or is optional (OP). This catalog has them all. The interchange column shows you if a part supersedes (I), is prohibited (P), or works in combination (T). You can trust that a part number from this 244-page document will match the casting number on your EX220.

The automotive industry is full of shortcuts – Automotive Industry Overview shows how many non-OEM options exist, but for excavator parts, stick with Hitachi’s original. Automotive Industry Overview – same lesson applies.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque specs are in the factory service manual.

Can I cross-reference part numbers from this catalog to order from a dealer?

Absolutely. The catalog includes the Hitachi factory part numbers alongside interchange codes (I, P, T, Y) that tell you if a part supersedes or is replaced. The numerical index at the end lets you look up any number. Dealer parts counter will recognize these numbers immediately. The service codes (W, D, K, etc.) clarify whether a part is a standalone service item or part of a kit – that level of detail prevents you from ordering a solenoid that requires a separate wiring harness you didn’t know about. If you follow the numbers exactly, you will get the right part.
