Ihimer 80VX, 80NX3 Parts Catalog – Factory OEM Parts List

You pull a part off an 80VX and the number on it is half worn off. Order the wrong one and you lose a day waiting on the next truck. That’s where this Ihimer 80VX, 80NX3 Parts Catalog earns its keep. 190 pages of factory part numbers, exploded views, and serial number applications. No guesswork. No aftermarket cross-reference that may or may not fit. This is the document the dealer uses when you call needing a swing motor seal kit or a track adjuster seal. Every page is a direct reproduction of what IHI Construction Machinery Limited originally published. If you own an 80VX or 80NX3, this catalog is the difference between ordering the right part on the first try and paying restocking fees.

Lower Machine and Turntable: Serial Number Breakdowns

The catalog opens with LOWER MACHINE (page 1) and TURNTABLE (page 2). Each assembly is broken down by serial number range, shown in the remarks column. For example, the turntable Assy (part 5750 735 UA) covers serial numbers 26127 through 26169. After that, the part number changes. You need that serial number range to pick the correct motor assembly – 0750 724 UA for early machines, 0760 869 UA for later ones. The catalog uses symbols: x for discontinued parts, △ for special order. If you skip checking the serial number, you risk ordering a non‑interchangeable part. This section makes that check painless.

Hydraulic Piping and Instruments: Reading the Diagrams

HYDRAULIC PIPING (section 4) and HYDRAULIC INSTRUMENT (section 5) cover every hose, fitting, and valve. The parts list gives you the exact O‑ring size and the quantity needed per assembly. One look at the diagram shows how the swing motor connects to the control valve. If you need the complete swing drive assembly, Section 3 (SWING DRIVE DEVICE) lists the motor and reduction gear as separate sub‑assemblies. The ‘remarks’ column tells you if a part is a sub‑component of a larger assembly using asterisk (*) marks. This saves hours of cross‑referencing against a parts lookup website.

Power Unit, Cab, and Electrical: Engine Parts Sourcing

Section 7 – POWER UNIT covers the engine mounting, fan, and radiator. Section 8 – CAB & RELATED PARTS includes the ROPS structure, seat, and glass. Section 9 – ELECTRIC SYSTEM gives you the wire harness and switch part numbers. Note: the catalog tells you to order engine parts from the engine manufacturer directly using their own parts catalog (page 3 of the front matter). That’s a critical detail – don’t call IHI for a piston ring. Use the OEM engine parts catalog instead. For everything else – blade control, hoe attachment, optional crane spec – this catalog identifies every bolt, bushing, and seal.

7 Sections Covering Core Systems

The catalog organizes 17 total sections, but the core mechanical systems are covered in these 7: (1) LOWER MACHINE, (2) TURNTABLE, (3) SWING DRIVE DEVICE, (4) HYDRAULIC PIPING, (5) HYDRAULIC INSTRUMENT, (6) POWER UNIT, (7) HOE ATTACHMENT. Each includes an exploded diagram with callout numbers that match the parts list. The index at the end lets you search by part number. If you need the noise absorber assembly for the 80VX, check out IHI 80 Miniexcavator Parts List – Noise Absorber – that manual expands on the cab interior parts. For blade control on the 14NXT, see IHIMER 14NXT Blade Control Assy Parts List and IHIMER 14NXT Mini Excavator Spare Parts Catalog.

Source Validity: Factory IHI vs Aftermarket Lists

Aftermarket parts catalogs often omit serial number splits or use generic diagrams. This catalog is an original IHI publication (Pub. No. 4). The front matter – in both Japanese and English – explains the symbol system exactly as the factory intended. You get the same information the assembly line used. For an overview of how the automotive industry handles parts documentation, see Automotive Industry Overview. Another useful reference is Automotive Industry Overview – it puts the complexity of factory cataloging in context. The bottom line: if you use aftermarket lookup tools, compare their part numbers against this catalog. The OEM source never lies about interchangeability.

FAQ

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views only.

How do I interpret the serial number ranges in the parts list?

The remarks column shows serial number ranges like “26127~” or “26127~26169”. The tilde means “from serial number X onward” or “from X to Y”. If your machine has serial number 26145, you need parts listed under “26127~26169”. The symbols (x, ★, △) tell you if a part is discontinued, supplied separately, or made to order. Always check the serial number before ordering – interchangeability is indicated by 〇 (interchangeable) or □ (not interchangeable) on the right side of the table.

Are engine internal parts listed here?

Engine parts are not in this catalog. The front matter directs you to the engine manufacturer’s own catalog. This manual covers everything bolted to the engine.

Can I use this to order the blade control valve for an 80NX3?

Yes. Section 12 covers BLADE ATTACHMENT with all valve and cylinder part numbers.

This catalog isn’t a repair manual – it’s a parts identification tool. When you need the exact part number for a swing motor seal or a track roller, you go here first. The 190 pages cover every assembly on the 80VX and 80NX3. If you want to cut down on wrong parts and lost time, access the factory manual today.
