Fiat Hitachi ZW310, ZW310-A Parts Catalog – OEM Factory Specs

You’ve got a ZW310 in the shop, transmission acting up, or a Valve body that needs rebuilding. Without the factory part numbers, you’re ordering based on a hunch. I’ve seen too many guys bolt up a wrong Brake component because they trusted a third-party parts list. This Fiat Hitachi ZW310, ZW310-A Parts Catalog is the real deal – 230 pages of OEM exploded views straight from the Japanese factory. Every seal, every shim, every hydraulic line traced back to the original part number. No aftermarket guesswork. If you’re maintaining a wheel loader, you need this book open on the bench.

Valve and Brake Sections: Factory Numbers, No Guesswork

Look at the TOC: VALVE MAIN (2SP), VALVE MAIN (3SP), VALVE BRAKE, VALVE CHARGE, VALVE STEERING. That’s ten separate valve categories. You get the exact part numbers for every spool, spring, and port. Same for the brakes – the catalog covers the brake valve and the entire axle assemblies (front and rear, TPD and LSD variants). Need a brake disc? The exploded diagram shows it with the OEM reference. Don’t waste time measuring – look it up.

Transmission Breakdown: 22 Sheets of Detail

The transmission section spans 22 separate pages. That’s not a quick reference – that’s a complete tear-down guide to the gearbox, clutches (Clutch Assy F, R, 1&2, 3&4), idler assembly, and valve assemblies. Each page shows the exact arrangement of parts. You want the clutch pack for the forward direction? Page number not given here, but the bookmark structure tells you exactly which sheet to open. Pair this with your shop manual for assembly order – the parts catalog gives you the what, not the how. That’s exactly what you need to order the right parts before you start.

Why OEM Parts Catalog Beats Aftermarket

I’ve used aftermarket parts lists. They’re usually a scan of a scan with blurred part numbers. This catalog is a clean scan of original Fiat Hitachi documentation. It covers both the ZW310 and ZW310-A models from serial number 000101 onward. The Japanese/English bilingual format keeps the technical density high. You get the part number, the diagram location, and the quantity. No marketing fluff. No “compatible with” disclaimers. If the part is listed, it’s the genuine factory item.

Audience Fit: Who Needs This Book

Home garage mechanics who rent their barn out for loader repairs? Not your typical car guy, but if you own a ZW310 or maintain a fleet, this is mandatory. Fleet supervisors, mobile heavy equipment techs, and DIY owners who hate dealer markups. The catalog is digital, so you can print the page you need and take it to the parts counter. No lugging a paper manual across the yard. If you can read an exploded diagram and cross-reference a part number, you’re qualified to use this.

Source Validity: From the Factory, Not Repackaged

This is a direct copy of the factory catalog – originally published by Hitachi Construction Machinery. The PDF metadata shows the original file name: HITACHI_ZW310-ZW310-A_Parts_Catalog_en-ja-53914020585.pdf. That’s the real deal. Compare that to aftermarket “digital reprints” that cut corners on image quality. You need the part number for a Regulator;Pump? It’s in the PUMP section. Need the Valve for the steering check? VALVE STEERING CHECK. Every bookmark matches the printed TOC. No missing pages.

FAQ

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views, not assembly torque values or procedures.

Can I use this for the ZW310-A model?

Yes. The catalog explicitly covers both ZW310 and ZW310-A wheel loaders from serial number 000101 forward.

Is this a digital access or a printed book?

Digital access. You get a 230-page PDF file that you can view on any device or print on demand. No shipping delays.

What about the engine section? I can’t find it in the table of contents.

This catalog focuses on the equipment components (pump, motor, valve, cylinder, power train, etc.). Engine parts (block, head, injection) are not covered. You’ll need a separate engine service manual for those. The pump section includes the hydraulic pump and its regulator, but not the engine itself.

Stop ordering parts based on a worn-out part number you can barely read. Get the factory breakdown that shows every component the way the assembly line built it. Access the Factory Manual and start ordering with confidence that the part will fit.
