Ihimer 18NXT Parts Catalog – Factory OEM Parts List for Mini Excavator

If you’ve ever ordered a part for a machine and ended up with the wrong seal, wrong bushing, or something that doesn’t even bolt up, you know the pain. Wasted time. Wasted money. Machine down while you send it back. That’s why Ihimer 18NXT Parts Catalog exists. This isn’t some aftermarket list thrown together from three different models. It’s the factory catalog — 184 pages — straight from Ihimer S.p.A. for the 18NXT mini excavator. I’ve been turning wrenches for 28 years, and I’ve learned the hard way: if you don’t have the OEM parts book, you’re guessing. Stop guessing.

Why a Factory Parts Catalog Beats Aftermarket Lists

Aftermarket catalogs copy numbers, but they don’t tell you about interchangeability. Page 1 of this catalog gives you the serial number range: CM200001 and up. Page 4 explains the symbols — which parts are supplied separately, which are special order, and which are no longer interchangeable. That’s the kind of detail you only get from the manufacturer. If you’re working on an 18NXT, you need to know that a part number change from 0750 729 UA to 0750 744 UA means the new part swaps in. The catalog shows you that. Aftermarket lists don’t.

What’s Inside – 13 Sections from Lower Machine to Parts Index

This catalog is organized the way a mechanic thinks. Sections cover every major assembly:

• LOWER MACHINE (TELAIO BASSO)
• TURNTABLE (TELAIO ROTANTE)
• SWING DRIVE DEVICE
• HYDRAULIC PIPING
• HYDRAULIC INSTRUMENT
• OPERATING CONTROLS
• POWER UNIT
• CAB, COVER & RELATED PARTS
• ELECTRIC SYSTEM
• TOOLS & ACCESSORIES
• HOE ATTACHMENT
• BLADE ATTACHMENT
• PARTS INDEX

Each section has exploded diagrams and a parts list with quantities, part numbers, and remarks. You don’t have to flip through 400 pages of generic hydraulic info. You go straight to the assembly that’s broken.

Reading the Catalog – Symbols and Interchangeability

You see a symbol like a diamond or a circle next to a part number? That means something. The catalog explains it on page 3: a part that cannot be supplied, a part supplied separately, or a special order part. There’s also the interchangeability coding. For example, if you have a part shown as 0750 659 UA with a note that the new part 0750 669 UA is not interchangeable, you need to know that before you order. This catalog gives you that warning upfront. No surprises when the box arrives.

Who Needs This Catalog?

If you own or work on an Ihimer 18NXT mini excavator, you need this. DIY mechanics who maintain their own equipment will save the cost of this catalog on the first order that doesn’t get returned. Professional shops will cut downtime because they can identify the correct part number and verify compatibility before the machine comes apart. Even parts counter guys need it — the factory parts index at the back lets you cross-reference by number. And if you’re rebuilding a hoe attachment or replacing a blade, the sections on HOE ATTACHMENT and BLADE ATTACHMENT are exact.

Source Validity – Why OEM Documentation Matters

This is the actual publication from Ihimer S.p.A., not a scanned third-party compilation. The catalog number is PUB. No.1, and it covers serial numbers from CM200001 forward. Every diagram, every part number, every quantity was approved by the engineers who built the machine. Aftermarket sources often leave out the “remarks” column — that’s where you find notes like “order from engine manufacturer separately” or “supplied as a set.” Miss that note and you’ll be short a bolt. This catalog doesn’t miss it.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the workshop manual.

Can I use this to repair the hydraulic system?

You can use it to order the correct hydraulic hoses, fittings, seals, and pump parts. The diagrams show how assemblies go together, but for disassembly and reassembly procedures, you need the corresponding workshop manual. The parts catalog ensures you order the right bits before you tear into the system, which saves hours of waiting. Once you have the parts, the service manual tells you how to install them.

How do I order parts using this catalog?

Look up the section for the assembly (e.g., Hydraulic Piping), find the diagram and item number, note the part number and quantity, then call your Ihimer dealer with machine name, serial number, part number, part name, and quantity. Check the remarks column for any special order notes.

Is this catalog for the 18NXT only?

Yes. It covers the 18NXT mini excavator with serial number CM200001 and later. Not for other models like the 14NXT or 80 series.

If you’re tired of ordering parts by guesswork and want a reference that’s verified by the factory, this is your tool. 184 pages of OEM part numbers, diagrams, and interchangeability codes for the Ihimer 18NXT. Access the Factory Manual and keep your machine running with the right parts every time.
