Hitachi Construction Machinery ZX210W Parts Catalog – 352 Pages of Factory Part Numbers

If you are ordering parts for a Hitachi Construction Machinery ZX210W wheeled excavator and you are tired of cross-referencing aftermarket catalogs that show the wrong seal kit or leave out the brake valve entirely, this is the document that fixes that. I have been wrenching on heavy equipment for 28 years, and I have seen more jobs held up by a wrong part number than by a broken machine. This Parts Catalog is the factory-issued book – 352 pages of exploded diagrams, part numbers, and interchange codes. It covers the pump, motor, valve, cylinder, and power train sections with the kind of detail that aftermarket houses cannot touch.

You need the right part for the control valve? The catalog breaks it into five sub-sections – VALVE ; CONTROL (1/5) through (5/5) – so you can pinpoint the exact spool or spring without ordering a whole assembly. Need a brake valve? It is listed under both the MOTOR section (VALVE ; BRAKE) and the VALVE section (VALVE ; BRAKE). That kind of redundancy is intentional – it saves you from flipping back and forth when you are elbow-deep in hydraulic fluid.

Valve and Brake Coverage – Factory Diagrams for Every Circuit

This catalog dedicates over 20 separate sections to valves alone. You get the pilot valve (front and swing), solenoid valve, relief valve, shuttle valve (five sub-sections), FC valve, lock valve, steering valve, and the brake valve. Each one comes with an exploded view and a parts list that includes the part number, quantity per assembly, and interchange codes. The brake valve section is critical – if you are rebuilding the travel motor or the swing motor, you need the correct seal and piston kit. The catalog shows you exactly which parts belong to which motor variant.

I have seen guys order a brake valve rebuild kit from a generic supplier and end up with a spring that is 2 mm too short. That does not happen when you use the factory catalog. The interchange codes (Y, T, P, etc.) tell you whether a part can be swapped or if it is superseded. Page 73 of the PDF (the VALVE ; BRAKE section) lists the part numbers for the brake valve assembly and its internal components. Do not guess – use the factory data.

7 Systems Covered – From Pump to Power Train

The table of contents is laid out by major system: PUMP, MOTOR, VALVE, CYLINDER, and POWER TRAIN. Under PUMP you get the pump device, pump unit, regulators (right and left), and gear pump. The MOTOR section covers the swing oil motor and travel oil motor, plus the brake valve. The CYLINDER section is massive – boom cylinders (right and left, mono boom and 2-piece boom), arm cylinders, bucket cylinder, positioning cylinders, ram cylinder, blade cylinder, and outrigger cylinder. Each cylinder variant includes the holding valve if applicable.

Under POWER TRAIN you get the front axle (six sub-sections, plus a wide version) and the rear axle (fourteen sub-sections, plus a wide version). If you are rebuilding a final drive or replacing axle seals, you need the exact bearing and shim part numbers. The catalog gives you that. No aftermarket cross-reference – just the OEM number.

Does This Manual Cover the Fuel System?

This is a parts catalog for the hydraulic and power train systems. It does not cover the engine internal parts or the fuel injection system. For engine parts, you need the engine service manual from the manufacturer. What this catalog does cover is every hydraulic component, every valve, every cylinder, every axle assembly, and the associated hardware. If it moves oil or turns a wheel, it is in here.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, the part numbers are verified by the factory. Aftermarket catalogs often use their own numbering system, which means you have to cross-reference and hope you get the right part. Second, the exploded diagrams show the exact assembly order and orientation. Third, the interchange codes tell you if a part has been superseded or if it is restricted. You cannot get that from a third-party reprint.

I have a rule in my shop: if the job involves a valve body or a brake assembly, we pull the factory catalog. It saves time and it saves money. The Hitachi ZX210W Parts Catalog is the same document the dealer uses. It is not a condensed version – it is the full 352-page PDF.

Source Validity – OEM Factory Print, Not a Copy

This is a direct scan of the original Hitachi Construction Machinery publication (PCDB-E1-3). The file name is HITACHI_ZX210W_Parts_Catalog_en-ja-78214020613.pdf. It includes the Japanese and English text, the memorandum pages for recording serial numbers, and the full parts index at the back. The index lists every part number alphabetically so you can find a component even if you do not know which section it belongs to.

I have used aftermarket parts catalogs that were missing pages or had blurry diagrams. This one is clean, legible, and complete. If you are serious about keeping your ZX210W running, you want the factory document. Check out the Hitachi ZAX IS ZX130W-ZX210W Operator’s Manual for operating procedures, or the Hitachi ZX210W Workshop Manual for service procedures. The HITACHI ZAXIS 210W Wheeled Excavator Parts Catalog is the one you are looking at now.

Frequently Asked Questions

Does this catalog include torque specs for the valve and brake assemblies?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and interchange codes. Torque values are in the workshop manual.

Can I use this catalog to order parts for a ZX210W with a different serial number range?

The catalog covers machines with serial number 001002 and up. If your machine is older than that, some parts may differ. Check the interchange codes on each page – they indicate compatibility with earlier or later serial breaks.

How do I read the interchange codes in the parts list?

The codes are explained on page 5 of the catalog. Y means unconditional interchangeability. T means no combination interchangeability – you must replace the entire assembly. P means the part is prohibited and must be replaced with the alternate part number listed. These codes prevent you from ordering a part that will not fit.

What is the difference between the mono boom and 2-piece boom cylinder sections?

The mono boom uses a single-piece boom structure. The 2-piece boom has an articulation joint. The cylinder sections are separate because the hose routing, holding valve location, and cylinder stroke differ. The catalog lists both variants with their own part numbers and diagrams.
