Hitachi machines in the documented extract run Isuzu and Hino engines, and the listings follow that fact: two of the crankshafts below are engine parts (Isuzu 6BG1, Hino HO6CT/H07C) recorded against the Hitachi models they serve. Kyotechs also documents hydraulic pump repair kits for Hitachi pumps among its store listings, and IDSS — the Isuzu diagnostic system used on Hitachi machines — is one of the documented platforms in both the engine repair and hydraulic repair solutions.

Notes for Hitachi Buyers
- EX and ZAX naming overlaps. The crankshaft listing records both EX200-5 and ZAX230 — quote the model exactly as badged on your machine.
- Engine plates matter. Two of these listings are engine-led; the Isuzu or Hino engine model confirms them faster than the machine badge.
- Harness supersessions are recorded. The internal harness carries two numbers (0001044 / 4296401) for that reason — send whichever yours shows.
Delivery and preparation times are confirmed for your order in the enquiry reply, in writing and before payment: the reply states the times, the packing and the shipping method that apply to your exact part number. Times are confirmed per order rather than published as a general figure, because they follow the listing, the quantity and the destination.
Frequently Asked Questions
Are these parts made by Hitachi?
No — and this page does not pretend otherwise. Kyotechs is an independent aftermarket supplier; the parts listed are compatible with Hitachi machines. Each listing states its own specification and condition, and the enquiry reply confirms exactly what will ship.
Do the parts carry a warranty?
Warranty terms are confirmed in writing for each order before payment. Kyotechs' own FAQ states that most parts are backed by a warranty against manufacturing defects; ask for the term that applies to your listing when you enquire.
Hitachi Range Notes
The Hitachi extract spans three machine generations, and each generation asks for a different identification habit. The EX100/EX120 harness belongs to the pre-electronic era of the range: its match is physical — connector layout and harness routing — as much as numerical. The EX200-5 and EX220-5 crankshafts are engine business (Isuzu 6BG1 and Hino power respectively), identified from the engine plate. The ZX470LC-5G cylinder head serves the current large generation, where the full number set including the suffixed variant (…46-6 / …46-5) is the identifier — quote both numbers if your head carries them. Across all three, the rule of this site holds: the listing is confirmed in writing against your number before payment, so a near-match is never shipped as a match.
One generation note for the ZX range: electronic content rises sharply in the newer machines, and Hitachi shares its engine diagnostics with the Isuzu IDSS platform used in Kyotechs' engine repair service — ZX machines appear in that service's recorded IDSS brand list (Hitachi, Case, Sany, Sumitomo, JCB, XCMG). A Hitachi enquiry that is half parts and half fault codes is normal here; send both halves in one message and the reply coordinates them.
