Fiat-hitachi EX160WD Parts Catalog – 260 Pages OEM Parts Data

Description

If you’re rebuilding a hydraulic pump on an EX160WD and you’re staring at a pile of parts wondering which valve goes where, you need this catalog. Not a generic exploded view from some third-party site that might be close. This is the OEM Fiat-hitachi EX160WD Parts Catalog – 260 pages of factory exploded diagrams, part numbers, and serial number applications. I’ve seen too many guys order the wrong Brake valve because they guessed. Don’t guess.

What Does This Parts Catalog Cover?

Everything from the pump and motor assemblies down to the smallest solenoid. The table of contents splits the machine into six major groups: PUMP, MOTOR, VALVE, CYLINDER, POWER TRAIN, and ETC. Under POWER TRAIN you’ll find PARKING BRAKE, BRAKE ; FRONT, BRAKE ; PROP., and all the axle and final drive components. Each valve section – CONTROL, PILOT, RELIEF, CHECK, LOCK, SHUTTLE, SOLENOID – has its own page with part numbers and quantities. You won’t find this level of detail in an aftermarket reprint.

Pump and Motor Breakdowns – Over 30 Sections

The PUMP group alone covers piston pump, control section, regulator cover, valve cover, rotary groups (drive and idler side), pilot gear pump, auxiliary pump, and gear pump. The MOTOR group splits travel motor, swing motor, and their relief valves. If you need the exact part number for the VALVE ; BRAKE inside the travel motor, it’s in the MOTOR OIL (TRAVEL) subsection. No guessing which O-ring or bolt goes where – the factory diagram shows you.

Why the Factory Catalog Matters

Aftermarket parts catalogs often reuse old photos or mislabel components. This one came straight from Hitachi. The foreword (in Japanese and English) explains how to read the diagrams, how to order parts, and what serial numbers apply. For example, the EX160WD serial number 1001 onward is covered. When you call a dealer with a part number from this catalog, you get the right piece. Period. Related manuals you might need: HITACHI EX160WD Parts Catalog, Fiat-hitachi 850-3, 850LC-3, 870H-3, 870LCH-3 Parts Catalog, and Fiat-hitachi ZX50U-2 Parts Catalog – 120 Pages of OEM Specs.

Valve Sections You Need to See

There are at least 25 distinct valve subsections: CONTROL (1/4 to 4/4), PILOT, STEERING, RELIEF, CHECK, LOCK, FC, HOLDING, BRAKE, SHUTTLE, SOLENOID. Each has its own exploded view with reference numbers. The HOLDING valve appears four times – don’t assume they’re interchangeable. The part numbers are different. Use the PARTS INDEX at the back of the book (page 260) to cross-reference any number. That index lists every part with its page location. The automotive industry Automotive Industry Overview depends on this kind of precision.

Brake and Powertrain – Critical Assemblies

The POWER TRAIN section covers TRANSMISSION, BEVEL GEAR SHAFT, COUNTER SHAFT, FRONT AND REAR AXLES, FINAL DRIVES, HUB REDUCTION, and both PARKING BRAKE and BRAKE ; PROP. (proportional brake). If you’re replacing a brake disc or seal, you need the exact part number – one digit off and the piston won’t fit. This catalog gives you the OEM reference, not a “universal” replacement number that may or may not work. Also check the BRAKE ; FRONT and BRAKE ; REAR subsections for wheel-end components. The same high standards apply across all Hitachi documentation – learn more from Automotive Industry Overview.

3 Reasons to Order Parts from This Catalog

First, the exploded diagrams show every washer, snap ring, and seal – no parts hidden. Second, the part numbers are verified by Hitachi; aftermarket catalogs often use superseded numbers or omit revisions. Third, the parts index lets you find any component in seconds. Professional mechanics in my shop use these catalogs daily because they eliminate wasted time and wrong orders. The foreword explicitly tells you to quote the machine serial number when ordering – that’s the kind of detail you get from a real OEM document.

Using the Parts Index Correctly

Once you find the assembly diagram, note the reference number. Then flip to the PARTS INDEX at the end of the book. It lists every part number alphabetically and numerically. Cross-check the description – don’t rely on the reference number alone. Some assemblies share similar-looking parts. For example, the VALVE ; HOLDING appears four times under different cylinder circuits. The index will tell you which page each one lives on. That’s the only way to be sure you’re ordering the right piece.

FAQ

Can I use this catalog for the EX160WD serial number 1001-?

Yes, it covers machines from serial 1001 onward.

How do I find the correct part number for a control valve?

Go to the VALVE section. There are multiple subsections: VALVE ; CONTROL (1/4) through (4/4), plus pilot valves, steering, relief, check, lock, FC, holding, brake, shuttle, solenoid. Each has an exploded diagram with reference numbers. Match your valve’s physical appearance and location. Then use the parts index at the end to locate the part number. If you have the old part, compare it to the diagram. The catalog lists the part number and description. The part number is critical – one digit off and you get the wrong component. Order exactly as shown. This is the same data the dealer uses.
