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

You’ve got a machine down, a broken hydraulic line or a fried starter, and the aftermarket catalog you pulled up online shows a part number that sort of looks right. That gamble costs hours and cash. I’ve seen it happen. This Fiat-hitachi LX190-7, LX230-7 Parts Catalog is the genuine Hitachi document – not a reprint or a third-party guess. It’s what the dealer pulls up when you call in. 466 pages of exploded views, part numbers, and serial number ranges that tell you exactly what fits your machine.

Engine and Cooling: Factory-Coded Components

The ENGINE section breaks out engine mount, engine control, and cooling system with separate entries for LX190-7 and LX230-7. The radiator has two FIG numbers depending on your machine’s serial number – check page 5 of the contents to see which applies. Inter cooler, fuel system, air intake and exhaust system, and air cleaner are all separated by model. If you need a fuel injector line or a radiator hose, you get the exact part number for your serial number range, not a generic cross-reference.

Fuel System and Air Intake: Separated by Model

FUEL SYSTEM is one section. AIR INTAKE & EXHAUST SYSTEM has two: one for LX190-7, one for LX230-7. Same for AIR CLEANER. That matters because the intake routing and filter housing differ between the two models. Ordering the wrong air filter element because a parts house listed one part for both? I’ve seen that too. This catalog kills that guesswork. Each illustration shows the exact bracket, clamp, and hose assembly with a factory part number.

Electrical Wiring: Every Harness and Component

The ELECTRICAL section is laid out by location: FRONT FRAME WIRING, COCKPIT WIRING (two sub-sections), REAR FRAME WIRING, ENGINE WIRING, BATTERY CABLE, BATTERY. Then you get INSTRUMENT PANEL, CLUSTER METER, relays, switches, horn, buzzer, even the car stereo and road regulation kit as options. If you’re chasing a short in the cockpit or need a replacement wire harness for the rear frame, the part number is right there in the exploded drawing. I’ve had to trace wiring on these loaders without a diagram – this catalog gives you the harness assembly number so you can order the right one, not a universal replacement that takes three hours to modify.

Powertrain: Drive Axle, Transmission, Torque Converter

POWER TRAIN covers the drive unit in five sub-sections, transmission control valve, clutches (forward/reverse, 1st/2nd, 3rd/4th), torque converter, charging pump, and drive axles for both front and rear, each split by model. Planet carrier, wheel & tire, propeller shaft – all broken out. The DRIVE AXLE (FRONT) sections for LX190-7 and LX230-7 are separate, so you get the right ring and pinion parts. 466 pages of this level of detail. Need a planet carrier gear? Look up the FIG number, find the illustration, and order the factory part. No cross-referencing aftermarket numbers.

Source Validity: Why OEM Parts Catalog Beats Aftermarket

This is an official Hitachi publication, PW-671F(H), covering LX190-7 serial number 004101~ and LX230-7 serial number 002101~. Page 4 tells you how to order parts – you must specify model, serial number, part number, and quantity. The manual includes both English and Japanese text, with the original Japanese part names and abbreviations. Every illustration is keyed to a FIG number. I’ve used enough aftermarket catalogs that list parts for “similar” models and end up with the wrong bearing. This one is the source. It’s what the dealer uses. If you’re rebuilding a drivetrain or replacing a hydraulic component, you want this open on the bench.

Can I use this parts catalog for a different model of wheel loader?

No, it’s strictly for the LX190-7 and LX230-7. Other models have different part numbers and illustrations.

Does this manual include torque specifications or repair procedures?

No, this is a parts catalog – it lists part numbers, quantities, and exploded views. It does not contain service procedures or torque values. You need the shop manual for that.

How do I find a part number if I know where the part sits on the machine?

Start with the CONTENTS on page 5. Find the section that covers that area – for example, if it’s a bracket on the front frame, look under FRAME. Each section has a FIG number. Turn to that FIG number. The illustration shows each part with an index number. The parts list below gives the part number, description, and quantity. Always check the serial number range near the FIG title – some parts change at a certain machine serial number. The manual is organized by location, so if you know where the part lives, you can find it in under a minute. Use the PARTS NUMBER INDEX at the back if you already have a part number and need to verify it.

What is the difference between the LX190-7 and LX230-7 sections?

Many sections have separate FIG numbers for each model – for example, AIR INTAKE & EXHAUST SYSTEM (LX190-7) and (LX230-7) are different drawings because the engine and piping differ. Always select the FIG number that matches your machine model.

This catalog goes on the tablet next to the machine. You’ll use it every time you order a seal kit, a hydraulic line, or a wiring harness. Don’t gamble an afternoon on a misrouted part number. Access the Factory Manual.
