Description

Hitachi ZAXIS 240-3 and 250 Series Parts Catalog — Equipment Components

This is the equipment components parts catalog for the Hitachi ZAXIS 240-3 and 250 Series hydraulic excavator range. It covers the internal components that make up the machine’s hydraulic and powertrain assemblies: pumps, motors, swing and travel devices, control and pilot valves, cylinders, oil filters and the centre joint. Every page is built around exploded illustrations keyed to numbered item tables, so a part can be identified visually and then confirmed by part number, service code and quantity.

The catalog is printed bilingually in Japanese and English, with the how-to-order and symbol explanation sections additionally provided in Dutch, German, French, Italian, Spanish, Danish, Portuguese, Norwegian, Swedish and Finnish. Applicable machine serial numbers are shown as 020001-, and the engine listed for the ZAXIS240-3 is the ISUZU AH-4HK1XYSA-01.

Across these chapters the catalog breaks each assembly down to the level of casings, sleeves, spools, pistons, springs, seals, O-rings, back-up rings, bearings, retaining rings, bolts, plugs, adapters and name plates. Every one of those items carries its own part number and quantity, and assemblies are shown both as complete units and as their constituent parts, so you can order either a whole regulator or the single spring inside it.

How the Catalog Is Organised

Each chapter opens with a large exploded illustration with callout numbers, followed by a parts table that repeats those numbers against part number, part name, code, quantity, service code, applicable serial number and interchangeability. Assemblies appear with a leading dot marker in the part name column, which shows they belong to the parent assembly directly above them. Sub-assembly pages such as the five-part control valve breakdown and the five-part shuttle valve breakdown carry their own item tables while referring back to the parent assembly, so nothing is double-listed and nothing is missed.

Part Numbers, Codes and Interchangeability

The catalog carries two identifier columns for every line: the part number and a separate code. Symbols in the service code and interchangeability columns flag the conditions attached to an individual item. These include parts that cannot be replaced singly and must be exchanged as an assembly, parts contained in a service part kit, shim-type items whose quantity varies by machine serial number, oversized and undersized variants, optional parts not fitted to the standard specification, and parts that require additional processing at the job site. Replacement part numbers and quantities are listed alongside where a superseded or interchangeable item applies. Notes at the front of the catalog explain how each symbol is read and how substitution is handled when an order is placed.

Who This Catalog Is For

Anyone rebuilding or resealing a hydraulic component on a ZAXIS 240-3 or 250 Series machine will find the exploded views and item tables let them see how a regulator, control valve spool stack, swing motor or boom cylinder comes apart before touching the machine, and then order exactly the seal, ring, spring or spool that is needed. The serial number column matters here, because several items change across the production run and the catalog tells you which part applies to which machine. Fleet workshops, independent hydraulic repair shops and parts counters can all work from the same reference.

What You Can Do With This Parts Catalog

With the Hitachi ZAXIS 240-3 and 250 Series Excavator Parts Catalog open you can identify a component from a photograph of the assembly or from a part number already in hand, confirm whether the item is sold on its own or only as part of a larger unit, check the quantity required per machine, and establish which revision applies to a given serial number. That removes the guesswork from ordering, cuts the number of wrong parts arriving on site, and gives a technician the assembly sequence in visual form before a spanner is picked up.

Correct part identification is what keeps a hydraulic repair on schedule. A control valve resealed with the wrong back-up ring, or a travel motor rebuilt without the correct retaining ring, means a second strip-down, a second set of seals and a machine sitting idle. Working from the exploded views and the numbered tables in this catalog means the parts list is confirmed before the assembly is opened, not after.
