Fiat-hitachi EX220-3, EX220LC-3 Parts Catalog

You need a part number for a brake valve on a Fiat-hitachi EX220-3 and the aftermarket catalog gives you six different options. Which one fits? That downtime costs you billable hours and eats into your shop rate. I have seen techs order the wrong pump gear twice in one week because they trusted a third-party parts list. The Fiat-hitachi EX220-3, EX220LC-3 Parts Catalog from AutoRepairManuals stops that. It is the exact same document the dealer parts counter uses – 164 pages of OEM part numbers, exploded diagrams, and serial number ranges. No guesswork. No returns because the part didn’t match.

Pump and Motor Sections: Where the Power Flows

The catalog opens with the pump group – double pump, pump unit, angle sensor, gear pump. Each gets its own chapter with a clear parts breakdown. Need the travel motor assembly? It is in the MOTOR; OIL section, broken into travel motor, brake valve, relief valve, and servo piston. The brake valve page shows every seal and spool. I have used this to find a $12 O-ring that kept a machine from building travel pressure. If you are rebuilding the swing motor, the swing motor chapter has its own brake valve and relief valve listings. The parts index at the back cross-references every number, so you can verify before you order.

Brake Valve and Travel Motor: Get the Right Part Number

Brake valves are safety-critical. Order the wrong relief valve cartridge and the machine could fail to hold on a slope. This catalog lists the valve; brake components with factory part numbers and quantities. For the travel motor, the brake valve is separate from the relief valve – two distinct sections. The catalog shows you exactly which valve goes with which serial number. It also marks service codes: D means you cannot buy the valve alone, you must buy the whole assembly. That alone saves you from wasting money on a part you cannot use. The same logic applies to the holding valve and lock valve in the valve section – all OEM, all verified.

Control Valve Coverage: What the 6 Sheets Tell You

The control valve is the heart of the hydraulic system. This catalog dedicates six separate sheets to the control valve – each one covers a different section of the spool bank. You get exploded views of the control valve (1/6) through (6/6), and then a second set for the EX220LC-3. Each sheet lists every plug, spring, and sleeve with a part number. If you need a shuttle valve or FC valve, they have their own subsections right after the control valve. The pilot valves and solenoid valves are also there. This level of detail is what you pay for – aftermarket catalogs throw all control valve parts into one paragraph and hope you can figure it out. This manual does not do that.

Cylinder Parts: Boom, Arm, and Bucket Exploded Views

Cylinder rebuilds are common on excavators. The cylinder section covers boom (right and left), arm, bucket, and even river maintenance variants. Each cylinder gets its own page with the rod seal, piston seal, gland, and wiper listed separately. Part numbers are right next to the quantity. If you need an arm cylinder for a river maintenance machine, the catalog lists it separately. The same goes for the bucket cylinder. You will not guess which cross-reference to use – the catalog tells you. The parts index at the back includes page references so you can jump directly to the cylinder you need.

Parts Index: 164 Pages of Factory Data

Every part number in this catalog is keyed to the factory parts index. The index lists part numbers in numeric order and tells you which page to look at. That is critical when you have a box of unlabeled parts and need to match them to the diagram. The catalog also uses service codes: W for local machining needed, K for service kit, OS for oversize, US for undersize. You see those codes next to the part number. No interpretation needed. This is the same information a dealer parts department uses to fill orders. If you work on Fiat-hitachi equipment, this manual belongs on your bench.

Who Actually Needs This Parts Catalog?

Home garage enthusiasts who own an EX220-3 or EX220LC-3 and do their own maintenance. Small shop owners who cannot afford parts ordering mistakes. Mobile technicians who rebuild pumps and travel motors in the field. Beginners who are just starting to work on excavators – this catalog will teach you how to read an exploded view and match part numbers correctly. The Fiat-hitachi Parts Catalog is not a repair manual; it is the parts bible. Pair it with a factory service manual and you have the complete picture. Access it, put it on a tablet in the shop, and stop guessing.

Does this catalog include torque specs for the brake valve?

No. This is a parts catalog, not a repair manual. It lists part numbers, quantities, and service codes. Torque values are not in this document. You need the factory service manual for that.

Can I use this catalog to identify parts for an EX220-3 with a serial number below 10001?

Yes. The cover notes serial number 10001 and up, but most internal components are the same. If you have an early machine, double-check the pump and control valve sections – there may be minor variations. The parts index will help you confirm.

How many pages is it?

164 pages.

What is the difference between the EX220-3 and EX220LC-3 sections in this catalog?

The EX220LC-3 is the long-track version. The undercarriage parts differ, but the upper structure (pump, motor, valve, cylinder) is largely shared. This catalog shows separate exploded views for the control valve (both standard and LC) and includes both variants in the cylinder section. The parts index covers both models, so you can find the correct part number regardless of track length. Pay attention to the model designation next to each part number – the catalog uses the model name in the part description. For example, some boom cylinders are listed as EX220LC-3 only. If you miss that, you might order the wrong cylinder. The catalog helps you avoid that because it prints the model name right there. Also note that the travel motor and brake valve assemblies are identical between the two models, but the frame and track frame parts are not. The catalog clearly separates those sections. If you are working on an LC variant, always check the valve; brake section to ensure the brake valve number matches your serial number range. The factory updates those parts over time, and this catalog reflects the latest revisions as of its publication. No third-party catalog will give you that level of precision.
