Hitachi Sumitomo ZAXIS450, ZAXIS450LC, ZAXIS450H, ZAXIS450LCH, ZAXIS460LCH Parts Catalog

If you are ordering parts for a ZAXIS450, ZAXIS450LC, ZAXIS450H, ZAXIS450LCH, or ZAXIS460LCH, you need the factory parts catalog. Not a third-party reprint. Not a scanned copy of a copy. You need the original Hitachi Sumitomo document that tells you exactly which part number goes where, and which models share components. I have been wrenching on heavy equipment for 28 years, and I can tell you: the difference between a job that takes two hours and one that takes two days is often a single wrong part number. This catalog eliminates that guesswork.

820 pages. That is not a typo. Every page is an exploded diagram with callouts, part numbers, quantities, and model applicability codes. The manual covers the ZAXIS450, ZAXIS450LC, ZAXIS450H, ZAXIS450LCH, and ZAXIS460LCH. It also includes the ZAXIS480MT and ZAXIS480MTH. If you work on any of these machines, this is the only parts catalog you should trust.

Upperstructure Breakdown: Frame, Counterweight, and Engine Mounts

The catalog opens with the upperstructure. Frame sections are split by counterweight type: ride-on type and fit-in type. Each frame page lists the specific model variants — <450, H, MT, MTH> or <460>. You get separate exploded views for the ride-on counterweight and the fit-in counterweight. The counterweight support brackets are also broken out by type. If you are replacing a counterweight or repairing a cracked frame mount, you need the exact part number for your machine. This catalog gives it to you.

Engine support pages are separated by counterweight type as well. Ride-on type counterweight machines get one set of brackets; fit-in type machines get another. The oil filter piping and engine oil drain piping sections show every hose, clamp, and fitting. Do not guess which O-ring goes where. Page 73 shows the engine support assembly for ride-on type machines. Use it.

Cooling and Air Intake Systems: Radiator, Reserve Tank, Air Cleaner

Radiator and radiator support pages are split by counterweight type. Reserve tank pages are model-specific: <450, H, MT, MTH> and <460>. Air cleaner and pre-cleaner sections are also separated by model group. If you are ordering a new air cleaner element or a pre-cleaner assembly, the part number changes depending on whether you have a ZAXIS450 or a ZAXIS460LCH. The catalog shows both.

Muffler section is common across all models. Fuel piping and fuel tank pages are split by model group. Fuel double filter and fuel feed pump sections are also model-specific. Do not order a fuel feed pump for a ZAXIS450H and expect it to fit a ZAXIS460LCH. The catalog tells you the difference.

Hydraulic System: Pump, Swing Device, Piping, and Control Valve

Pump device section covers the main hydraulic pump. Swing device is split into right and left, each with two pages. Swing device support brackets are also shown. Oil tank, suction piping, delivery piping, return piping, drain piping, and main piping sections are all model-specific. The catalog uses the <450, H, MT, MTH> and <460> tags to tell you which parts fit which machine. Pilot piping is broken into seven sections, some with multiple sub-sections. If you are rebuilding a pilot system, you need these pages.

Control valve section shows the main control valve assembly. Engine control cable, engine control motor, and engine stop cable sections are included. Control lever assemblies for front/swing and travel are model-specific. Lock lever and console sections round out the operator station.

Electrical System and Cab Components

Monitor, radio, control unit, and electric parts sections cover the entire electrical system. Electric parts are split into seven sections, with model-specific variants for <450, H, MT, MTH> and <460>. Head lamp, fog lamp, boom light, overload alarm, and motion alarm sections are included. Air-conditioner sections cover the unit, compressor, ducts, and rear box. Cab sections are extensive: cab support, cab (standard, with guard seat, with vandal hook, OPG), cab guard, and window guard. Each cab variant has its own exploded view.

If you are replacing a cab glass or a seat, you need the correct part number for your cab type. The catalog lists every nut, bolt, and seal.

Source Validity: OEM Factory Document, Not Aftermarket

This is a genuine Hitachi Sumitomo parts catalog. The OCR excerpt shows the original Japanese and English text, including the foreword that warns about product improvements. The catalog includes the service code symbols: W (local fabrication required), H (precision part – contact dealer), D (assembly only – no individual replacement), K (included in servo/pilot kit), R (quantity varies per machine), S (service part), Z (engine-related), OP (optional), OS (oversize), US (undersize). These codes are critical when ordering. Aftermarket catalogs omit them. This one does not.

The catalog also includes the interchangeability codes: Y (unconditional compatibility), I (interchangeable with restrictions), T (compatible in combination), P (prohibited – use replacement part). If you are trying to use a part from a different model, these codes tell you whether it will work. You will not find this data in a generic parts list.

Who Needs This Catalog

If you own or maintain any of these machines — ZAXIS450, ZAXIS450LC, ZAXIS450H, ZAXIS450LCH, ZAXIS460LCH — you need this catalog. It is also useful for the ZAXIS480MT and ZAXIS480MTH. Shop owners, fleet managers, and independent mechanics will save time and money by ordering the right part the first time. Beginners should use this catalog alongside the service manual. The parts catalog shows you what goes where; the service manual tells you how to install it.

Frequently Asked Questions

Does this catalog cover the ZAXIS480MT and ZAXIS480MTH?

Yes. The catalog includes those models. The model codes and appear throughout the upperstructure, cab, and electrical sections.

Are engine parts included in this catalog?

Engine parts are not listed here. The foreword states that engine parts are in a separate diesel engine parts catalog. This catalog covers everything else: frame, hydraulics, cab, electrical, and attachments.

How do I read the model applicability codes?

Each page header shows codes like <450, H, MT, MTH> or <460>. The legend on page 3 explains: <450> = ZAXIS450 and ZAXIS450LC; <460> = ZAXIS450LCH; = ZAXIS450H and ZAXIS450LCH; = ZAXIS480MT; = ZAXIS480MTH. If your model is not listed on a page, those parts do not fit your machine.

Can I use this catalog to order parts for a ZAXIS460LCH?

Yes. The ZAXIS460LCH is covered under the <460> code. The catalog includes frame, counterweight, fuel tank, air cleaner, electric parts, and cab sections specific to the 460LCH. Page references for the 460LCH are clearly marked.
