Hitachi Excavator Parts: ZX Series, EX Series, and Fiat Hitachi Coverage

Hitachi's excavator range is the backbone of its construction equipment business, and the ZX Zaxis series is the dominant platform operating in fleets worldwide today. Imara Engineering has structured its Hitachi spare parts inventory around this reality, prioritising coverage depth on the highest-demand ZX models while also carrying component ranges for older EX series machines and legacy Fiat Hitachi equipment that continues to operate across global fleets.

Hitachi ZX Zaxis Series Excavator Parts

The ZX Zaxis series spans compact through to large mining-class excavators, all sharing Hitachi's advanced closed-centre load-sensing hydraulic architecture. Imara Engineering stocks hitachi excavator parts for the ZX85, ZX130, ZX200, ZX210, ZX225, ZX240, ZX270, ZX300, ZX330, ZX350, ZX450, ZX490, and ZX870 series. Component coverage includes undercarriage assemblies, hydraulic pumps, swing motors, travel motors, final drives, boom and arm cylinders, bucket pins and bushings, track shoes, rollers, idlers, sprockets, and engine service parts.

The mid-range ZX Zaxis models run Isuzu diesel engines,s primarily the 4HK1 and 6HK1 power units, and Isuzu engine parts for these applications are available through our engine brands range for operators managing engine-level repairs alongside their Hitachi spare parts requirements.

Hitachi EX Series and Fiat Hitachi Legacy Parts

Before the ZX platform, Hitachi's EX series set the standard for mid-range excavation. A significant number of EX200, EX300, EX400, and EX550 machines remain in active operation globally, particularly in developing markets and long-lifecycle fleet environments. Imara Engineering carries used Hitachi parts and OEM components for the EX series, along with Fiat Hitachi parts for legacy joint-venture models, including the FH200 and FH300 produced during the Fiat-Hitachi Construction Equipment partnership. Provide your machine model and serial number, and our team will confirm availability and lead times.

Hitachi Hydraulics: Why Specification Precision Determines Performance

Hitachi's engineering identity is built around its hydraulic system design. The closed-centre load-sensing architecture across the ZX Zaxis range operates within tighter pressure tolerances than many competing excavator platforms, delivering the metering precision and cycle speed that make Hitachi the preferred choice on controlled excavation and tight-tolerance civil work.

This has a direct implication for how Hitachi parts are sourced and selected. Components that are marginally out of specification in pump displacement tolerances, valve spool clearances, or seal material grade do not simply wear faster in a Hitachi hydraulic system. They push the system outside its calibrated pressure envelope, generating excess heat, accelerating wear in adjacent components, and degrading machine response in ways that operators notice on the controls before any fault code appears.

At Imara Engineering, hydraulic components for Hitachi machines are sourced against dimensional and material specifications, not just part number proximity. This standard applies whether you are ordering Hitachi spare parts online or engaging our team for a direct sourcing request on a non-catalogued component.

Genuine, OEM, or Aftermarket: Selecting the Right Hitachi Parts

The right supply tier is determined by the component's function and the machine's operating context. Imara Engineering stocks all three and provides the application guidance to use them correctly:

  • Genuine Hitachi spare parts are Hitachi-branded, carry OEM warranty, and are the correct choice for precision hydraulic internals, electronic control units, and structural components where factory specification is contractually or operationally non-negotiable.
  • OEM Hitachi parts are produced by the same supply-chain manufacturers supplying Hitachi's assembly lines, to identical engineering drawings and material tolerances. These deliver full OEM performance for most mechanical, powertrain, and undercarriage applications at a more competitive price point.
  • Aftermarket Hitachi parts are the value-matched choice for high-consumption wear items: filters, track components, bucket teeth, cutting edges, seals, and gasket kits. Replacement frequency makes cost-per-cycle the primary driver on these components, and quality aftermarket Hitachi spares meet that requirement without compromise on specification.

How to Order Hitachi Spare Parts Online from Imara Engineering

Ordering Hitachi spare parts online through Imara Engineering is built around accuracy first, then speed:

  1. Locate your machine serial number: Stamped on the frame or cab plate. This determines your exact production specification and the correct part variants for your machine.
  2. Identify your requirement: Use the OEM part number from your Hitachi service manual, or provide the component description and machine details. Our team cross-references against the Hitachi parts catalogue to confirm the correct match.
  3. Select your supply tier: Genuine, OEM, or aftermarket. Our team advises where the decision requires application knowledge.
  4. Place and track your order: All orders are dispatched globally with full freight documentation and tracking for international customers across Australia, the  USA, Canada, and worldwide.

High-turnover Hitachi spares, including filters, seals, and undercarriage wear items, are held as ready-to-ship stock. Contact our team directly for urgent breakdown sourcing.
