Fiat-hitachi LX150-2 Parts Catalog

If you’ve ever ordered a hydraulic pump for a wheel loader and ended up with a part that didn’t fit, you know the pain. That’s what happens when you rely on aftermarket parts catalogs or generic cross-reference lists. The Fiat-hitachi LX150-2 Parts Catalog is the only way to get the exact part number that matches your machine’s serial number. I’ve seen guys spend half a day hunting down a $15 O-ring because they didn’t have the right catalog. This one is 612 pages of OEM data, printed in Japan by Hitachi Construction Machinery. It’s not a service manual—it’s a parts catalog, and it’s the difference between a job that takes two hours and one that takes two days.

Let me tell you why this catalog matters on the bench. Every serial number plate on your LX150-2 is documented here—manufacturing number, product identification, engine, transmission, hydraulic pump, axle, cab. The manual shows you exactly where to find them. Page 3 (the serial number location section) tells you that the product identification plate is on the left-hand side of the engine frame, to the right of the top step. That kind of detail saves you from crawling under the machine looking for a tag that isn’t there. The catalog also includes the alphabetical index that covers every major system: Engine, Transmission, Axles and Suspension Systems, Steering System, Service Brakes, Electrical System, and more. You want the part number for a loader bucket pin? It’s in the LOADER section. Need a seal for the hydraulic pump? Check the ENGINE AUXILIARY SYSTEM group. The index is organized by function, not by vague categories.

Serial Number Location: Stop Guessing

Every LX150-2 loader has up to eight serial number plates. The catalog shows you where each one lives. The transmission serial number is on the lower right-hand side of the transmission case. The engine serial number is near the oil filter. The cab serial number is inside the operator’s station on the horizontal cross tube behind the seat. Automotive Industry Overview might give you general knowledge, but this catalog gives you the specific picture. If you order parts without matching the serial number, you’re gambling. This catalog eliminates that gamble.

Axles and Suspension Systems: What the Catalog Covers

The alphabetical index lists AXLES AND SUSPENSION SYSTEMS as a dedicated section. The LX150-2 uses John Deere 1400 series axles, and the catalog includes the serial number plate location for those axles (input side of the differential case). When you’re looking for a differential bearing or axle seal, the catalog gives you the OEM part number—not an aftermarket cross-reference that might be wrong. I’ve had aftermarket parts catalogs give me a seal that was 2mm too thick. That doesn’t happen with the factory Hitachi document.

Transmission and Engine: Critical Part Numbers

Transmission parts are in their own index group. The catalog covers the transmission case, internal components, and the serial number plate location. The engine group includes the short block, engine auxiliary systems, and the serial number plate. Each part is shown with an exploded view (not in the PDF excerpts, but typical of parts catalogs) and a part number. The catalog also lists the manufacturing number plate format: for LX150, it’s 42E-02101- and up. You need that number to order anything from the factory.

3 Reasons to Choose OEM Parts Catalog over Aftermarket

First, aftermarket parts catalogs often use generic part numbers that don’t supersede correctly. Second, they skip serial number breakpoints—a critical mistake when a machine was updated mid-production. Third, they don’t include the introduction and customer information section that tells you how to verify part numbers through the dealer’s microfiche. The Lexus LX150-2 catalog is the original factory document. It’s not a reprint or a scan of a scan. HITACHI LX150-2 Parts Catalog is the exact same one we have here. If you’re working on a fleet, you’ll also want Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog and Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs.

Audience: Who Needs This Catalog

This is for the shop owner who has a LX150-2 in the yard and needs to order a steering cylinder or a brake caliper. It’s for the equipment dealer who stocks parts for multiple serial number ranges. It’s for the DIY mechanic who bought a used loader and wants to fix it without buying three wrong parts. The catalog is 612 pages, printed in Japan in 1992, but the part numbers are still current for most machines. You’ll need to verify with your dealer for superseded parts, but the catalog gives you the starting point. The introduction says: “THE PART NUMBERS IN THIS PARTS CATALOG WERE CORRECT AT THE TIME YOUR CATALOG WAS PUBLISHED.” That’s honest. Work with it.

FAQ

Does this parts catalog include service procedures like torque specs or repair steps?

No. This is a parts catalog, not a service manual. It lists part numbers, exploded views, and serial number locations. For repair procedures, you need the separate service manual.

How do I use the serial number information to order the correct part?

Locate the manufacturing number plate on your machine (left-hand console front surface). The format is 42E-02101-. Match that to the serial number range in the catalog. Each part in the catalog is listed with a serial number breakpoint. For example, a part may be valid for serial numbers 02101-03000. If your machine is outside that range, the catalog will show a different part number. Use the numerical index at the back to find the part number by group. Then call your dealer with the part number. The catalog also includes a product identification number plate (DW L150 E 012345 style) that you can use for ordering. The key is to provide all characters from the serial number plate—the catalog warns that “THIS POINT CANNOT BE OVEREMPHASIZED.” I’ve seen warranty claims denied because a tech left off one digit. Don’t be that guy.

So if you’re tired of ordering parts that don’t fit, or if you just bought a used LX150-2 and want to know what you’re working with, get the factory document. Automotive Industry Overview won’t help you order a hydraulic pump seal. This catalog will. Download the Factory Manual and stop guessing.
