Fiat-hitachi LX190-7, LX230-7 Parts Catalog

If you’re tearing down a Fiat-hitachi LX190-7 or LX230-7 wheel loader and you don’t have the factory parts catalog in front of you, you’re working blind. I’ve seen guys order the wrong seal three times because they trusted a third-party diagram. This catalog is 466 pages of OEM exploded views, part numbers, and serial number breakouts. No guesswork.

Engine, Cooling, and Fuel System Breakdown

The Engine section covers mounts, controls, and the cooling system – including separate radiator entries for early and late serial numbers (LX190-7 up to -4103, LX230-7 up to -2110). The intercooler and Fuel system are right after. Air intake and exhaust are split by model, same for air cleaners. Each assembly has its own figure number. Page 5 in the TOC shows the full section map. You need a radiator hose for a LX230-7 with serial 2111-? Go to FIG. 4A. That level of specificity keeps your parts bin accurate.

Electrical and Wiring: Factory Schematics

Wiring is where most aftermarket guides fall apart. This catalog gives you front frame wiring, cockpit wiring (in two parts), rear frame wiring, engine wiring, battery cable, and the whole dash – instrument panel, cluster meter. It also lists every relay, switch, horn, buzzer, and even the optional car stereo and road regulation kit. If you’re chasing a short in the wire harness, you need the exact connector part numbers. They’re all here. Electrical parts are broken down by lamp, relay, and switch groups. No guessing which relay goes where.

466 Pages of Exact Part Numbers

Four hundred sixty-six pages. That’s not filler – that’s 466 pages of exploded diagrams and parts lists. Each figure number matches a specific assembly. The index at the back (Parts Number Index) lets you look up any part number and find which figure it appears on. I keep a copy in the shop and a digital one on my tablet. When a customer brings in a LX190-7 with a blown torque converter seal, I flip to the Power Train section – torque converter (1/2) and (2/2), charging pump, drive axles. Everything has a part number that traces back to Hitachi’s genuine parts system. No third-party reprints here.

Does This Manual Cover Optional Equipment?

Yes. The TOC lists optional kits: balance weights (CWA, CWB, CW045), cab less kit (ROCLS2), anti-pitching system (APS), high lift arm (HLA), air conditioner, cool box, fire extinguisher, and more. Each option has its own figure number and part breakdown. If your machine has the road regulation kit (RRE) or the 3-spool valve (AP3), you’ll find those sections. The manual also includes decal placement and service tools. Ordering the right bracket for the optional bucket leveler is straightforward when you know the figure number.

How to Read the Parts Catalog

Read the intro on page 4. It explains abbreviations – ASSY, RH, LH, AR, OP – and how to find a part number when you know the name or location. Search the contents for the section, find the FIG. number, then confirm illustration and machine number. That’s it. The Japanese text on page 3 echoes the same procedure. Don’t skip it. And always use genuine parts – the manual states they can’t guarantee trouble if you don’t. I’ve seen aftermarket seals fail in 200 hours. With the OEM part number from this catalog, you get the right thickness (t), number of teeth (z), and diameter (d).

Can I use this parts catalog for the LX230-7?

Yes. Both machines are covered in one catalog.

Does this catalog include torque specifications?

No, this is a parts catalog, not a service manual. It gives you correct part numbers for every component – engine, cooling, fuel, electrical, wiring, drivetrain, hydraulics. Torque values are in the factory service manual. But having the parts catalog in hand when you disassemble lets you order replacement seals, gaskets, and bearings before you start, so you’re not waiting on parts mid-job. I always pull the figure number and part numbers first, then cross-reference the service manual for torque specs.
