Hitachi Sumitomo ZAXIS180W Parts Catalog

You need a part for a ZAXIS180W. You pull up some third-party parts list, cross your fingers, and order a seal kit that doesn’t fit. Then the machine sits. I’ve seen it happen more times than I’ve seen a clean workbench. That’s why you want the factory Hitachi Sumitomo ZAXIS180W Parts Catalog — a 290-page document that doesn’t leave room for guesswork. Every part number, every illustration, every assembly breakdown comes straight from the source. No aftermarket reinterpretation.

Pump Section: Matching the Right Main Pump Unit

Under the PUMP heading you will find the main pump device assembly, the pump unit itself, left and right regulators, and the gear pump. If you have ever swapped a regulator on a ZAXIS180W without the correct part number, you know the pain of bleeding air for an afternoon. This catalog lists each regulator (R) and (L) separately, along with the gear pump assembly. You get exploded-view illustrations that show exactly how the shims and O-rings stack. No more disassembling a pump to find a snap ring size you can’t identify.

Valve Assemblies: Control, Pilot, Brake, and Shuttle

This is where the catalog shines. The VALVE section alone spans eight sub-sections for the control valve, plus pilot valves for front and swing, solenoid valves, relief valves, shuttle valves (five sub-sections), FC valve, lock valve, steering valve, and the brake valve. Each valve has its own page with part numbers for every poppet, spring, and seal. The brake valve is critical — if you order the wrong shuttle cartridge, the brake release circuit won’t hold. The catalog gives you the part number for the valve; brake assembly as a single line, so you order the correct unit. That means less downtime and no rework.

Cylinder Breakdown: Boom Options and Holding Valves

The CYLINDER pages cover boom cylinders for mono-boom and 2P-boom configurations (left and right), arm cylinders with or without holding valves, bucket cylinder, positioning cylinder, ram cylinder, blade cylinder, and outrigger cylinders. Each variant is broken down with its own holding valve assembly. If you have a machine with a 2P-boom, you need the right boom (L) cylinder with holding valve — the catalog shows that exact assembly. The holding valve check valve part numbers are listed separately. You won’t confuse a mono-boom seal kit with a 2P-boom kit because the part numbers are distinct.

Power Train: Front and Rear Axle Parts Identification

The POWER TRAIN section covers the front axle in six illustrated pages and the rear axle in fourteen pages. Each page details the bearings, seals, shafts, and housings. Rear axle brake components, hub assemblies, and planetary gear parts are all listed with individual part numbers. If you need a wheel seal for the rear axle, you can look up the axle sub-section (e.g., REAR 5/14) and find the exact seal part number. No need to pull the axle just to read a marking. The factory exploded views show which shim stack goes where.

Parts Index: 290 Pages of Verified OEM Numbers

The final section is a parts index sorted by part number. Every number that appears in the catalog is cross-referenced. If you have a part in your hand with a stamped number, you can look it up in the index and find which assembly it belongs to. The catalog also includes service codes: “W” for parts needing local modification, “D” for parts only sold as an assembly, “K” for service kit, “OP” for optional equipment. That saves you from ordering a seal that cannot be installed without machining. I keep a printed copy near the parts counter and use it before touching the computer.

FAQ

How many pages does this parts catalog have?

290 pages.

Can I use aftermarket part numbers instead of the OEM ones listed?

You can try, but you will waste time fitting something that was machined to a different tolerance. The OEM catalog gives you the exact Hitachi Sumitomo part number for every valve, brake assembly, pump component, and axle seal. Aftermarket catalogs often group parts by application but miss the subtle differences in revision levels. This catalog shows the original factory part numbers for the ZAXIS180W serial number range starting at 001001. If a part was superseded, the index will note it. Using OEM numbers means the part fits the first time. That matters when the machine is down and you are billing by the hour.
