Hitachi Sumitomo ZAXIS 450, ZAXIS 450H, ZAXIS 450LC, ZAXIS 450LCH, ZAXIS 460LCH Parts Catalog

If you’re ordering parts for a ZAXIS 450 series and using a third-party parts list, you’re wasting time and risking wrong parts. I’ve seen too many guys bolt on a fuel pump that doesn’t match because the aftermarket guide had the wrong supersession. This catalog fixes that. It’s the official Hitachi Sumitomo ZAXIS 450, ZAXIS 450H, ZAXIS 450LC, ZAXIS 450LCH, ZAXIS 460LCH Parts Catalog – 796 pages of factory diagrams, part numbers, and assembly breakdowns. No reprints, no generic drawings. You get the same binder that a dealer parts counter uses.

Engine and Fuel System: Exact Part Numbers

Look up the ENGINE section. You’ll find the mounting, oil filter piping, and fuel double filter. The catalog breaks down each assembly with callouts. For the 6WG1TQA engine, you’ll need the separate Isuzu diesel engine parts catalog (referenced in the preface). But for everything else – the radiator, reserve tank, air cleaner, muffler, and fuel piping – it’s all here. Each variant (ZAXIS 450, 450H, 450LC, 450LCH, 460LCH) has its own diagrams. The format uses brackets like <450> or <460> to tell you which machine uses which part. No guessing.

796 Pages of Exploded-View Diagrams

That’s not a typo. 796 pages of detailed illustrations. Every page is a high-res scan of the original factory print. You get the upperstructure – frame, counterweight, swing device, control valve, pilot piping, cab parts, and dozens of electric parts sections. Need the part number for a ride-on type counterweight support? Page numbers are sequential, so you flip to the FRAME section and find the correct variant. The catalog also includes a parts number index at the back. If you have a part number but don’t know where it goes, the index points you to the figure. That alone saves you from digging through piles of old invoices.

Does This Manual Include the ZAXIS 460LCH?

Yes. The ZAXIS 460LCH is listed in the title and in the contents. Look for <460> markers throughout. For example, the FRAME (1) section has a separate entry for FIT-IN TYPE COUNTERWEIGHT <460>. The cab sections also have dedicated pages for the 460LCH with options like OPG guard, vandal hook, and window guard. If you’re working on a 460LCH, this catalog covers it. The same applies to the 450H and 450LCH variants – they have markers. You won’t need to cross-reference two different manuals.

Counterweight Variations: Ride-On vs Fit-In

One area where the aftermarket gets it wrong is counterweight mounting. The ZAXIS 450 and 450H have two styles: ride-on type and fit-in type. The catalog separates them clearly. Look under COUNTERWEIGHT [RIDE-ON TYPE] <450,H,MT,MTH> and COUNTERWEIGHT [FIT-IN TYPE] <450,H,MT,MTH>. Each has its own support brackets and hardware. If you order a ride-on counterweight support for a fit-in machine, you’ll be drilling new holes. This catalog prevents that. The diagrams show the exact bolt pattern and part numbers. Trust the factory drawing.

Get the Right Part Number the First Time

Every part number in this catalog starts with the original Hitachi Sumitomo prefix. You can order directly from a dealer with confidence. The manual also includes a Product Identification Number (PIN) page at the front – fill it in and keep it with the machine. That way, when you call for parts, you have the serial number ready. The preface explains how to read the catalog: symbols, assembly marks (single dot for sub-components, double dot for sub-sub-components), and the note that engine parts are in a separate Isuzu catalog. Small details matter when you’re billing hours.

The manual is a PDF – full digital copy with searchable text. You can zoom in on the diagrams to see the part numbers. No blurry scans. I’ve used these on a tablet next to the machine. Much easier than flipping through a greasy binder.

Can I use this catalog to find torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers and assembly breakdowns. Torque values are in the separate service manual. You’ll need that for rebuilds.

How do I know which variant my machine is – ride-on or fit-in counterweight?

Check the serial number plate on the cab. The catalog uses product identification numbers (PIN) starting with 16JP. If you have a 450H with a ride-on counterweight, the diagrams marked <450,H,MT,MTH> under COUNTERWEIGHT [RIDE-ON TYPE] apply. If you’re unsure, measure the counterweight mounting. Ride-on types have a flat top with bolt holes on the side; fit-in types recess into the frame. The catalog shows both illustrations. Compare to your machine. When in doubt, order the support bracket and bolts by referencing the <450> or <460> marker – the part numbers differ. The catalog also includes a memo section where you can record your machine’s PIN, engine type, and engine serial number. Fill that out and keep it in the cab. It saves calls later.
