Ihimer 15NX2 Parts Catalog – Factory OEM Parts List for Mini Excavator

You pull a part off a 15NX2 and the number is worn off. You flip through three aftermarket catalogs, none match. The dealer wants your machine serial number, and you’re burning billable time. That’s exactly why you need the Ihimer 15NX2 Parts Catalog—factory-sourced, 182 pages of exploded diagrams and genuine part numbers, not a third-party reprint. I’ve been wrenching for twenty-eight years, and I’ve seen too many jobs hung up on a wrong seal or a bracket that looked right but wasn’t. This manual fixes that.

The catalog covers serial numbers WX000001 and WX100001 onward. Page 1 gives you the machine identification layout so you confirm your unit before ordering anything. That alone saves returns. The factory notes on page 3 explain exactly how to read part numbers, interchangeability codes, and symbols for parts that are not supplied separately or require special order. You get the same information the dealer’s parts counter uses.

What This Parts Catalog Actually Contains

Thirteen numbered sections break down every major assembly. Starting with LOWER MACHINE (section 1), then TURNTABLE (2), SWING DRIVE DEVICE (3), HYDRAULIC PIPING (4), HYDRAULIC INSTRUMENT (5), OPERATING CONTROLS (6), POWER UNIT (7), CAB, COVER & RELATED PARTS (8), ELECTRIC SYSTEM (9), TOOLS & ACCESSORIES (10), HOE ATTACHMENT (11), BLADE ATTACHMENT (12), and finally PARTS INDEX (13). Each section groups parts by function, not by random catalog numbers. That layout matches how you actually work on the machine—start at the undercarriage, move up.

If you need a hydraulic line for the swing drive, you turn to section 4, not flip through a generic index. The index at the back (section 13) cross-references every part number to the diagram where it appears. That’s the kind of structure you can trust when a customer is waiting and the part has to arrive Monday.

13 Major Sections: From Lower Machine to Blade Attachment

Each section contains exploded views with callouts. The quantity column tells you how many of each part per unit. The remarks column flags sheet numbers for detailed diagrams. You also get notes on interchangeability—codes like “0750 729 UA” indicate whether a part supersedes the old one or is not backward compatible. That data keeps you from ordering a new part that won’t fit your serial number range. The catalog uses imperial units where applicable, but most fasteners on these mini excavators are metric. Always double-check thread pitch against the diagram.

For engine parts, the catalog directs you to your local sales distributor or engine manufacturer—standard practice. It does not try to cover the engine block itself, because that’s a separate engine service manual. But everything bolted to the chassis, the swing gear, the control valve stack, the blade cylinder—it’s here.

Parts Index: How to Find the Exact Part Number

Section 13, the PARTS INDEX, lists every part number alphabetically (or numerically) with the section and reference number where it appears. You can start with a worn-out part in your hand, look up its number, and jump directly to the correct diagram. No hunting through twenty pages of hydraulic fittings. The index is dense—about six pages of closely spaced numbers—but it’s indexed exactly like a factory system. When you order, you need to provide machinery name, machinery number, parts number, parts name, and quantity. That’s listed clearly on page 3 of the catalog. Write it down before you call the dealer.

Read the Catalog Correctly

The front matter explains symbols: a diamond means the part cannot be supplied separately; a circle means supplied as a separate part; a triangle marks special-order items. Asterisks indicate compositional parts—one asterisk for a subassembly, two asterisks for parts within that subassembly. That hierarchy matters when you order a seal kit versus a complete cylinder. I’ve seen techs order the whole swing motor because they didn’t see the asterisk notation. Don’t be that guy. Read page 3 thoroughly before you start flipping diagrams.

Also note the “Sh.No.” abbreviation—sheet number. If a diagram has a note like “Detailed diagram provided separately” with a sheet number, look that up. It shows a close-up of the area you need. The catalog uses standard abbreviations: I.D., O.D., L, t, P, W/, AR. Know them before you order.

OEM vs Aftermarket: Why Factory Specs Matter

I have a stack of third-party parts catalogs on my shelf from eBay and unknown publishers. They get numbers wrong. They crop diagrams so you can’t see the bolt callout. They skip the interchangeability notes. This Ihimer catalog is the original factory print—page 2 is blank white, exactly as the OEM intended. The diagram on page 1 shows the serial number plate location. Aftermarket reprints often omit that page. You pay for the real thing here: no guessing if the part number is correct, no cross-referencing from a Chinese clone manual. Ihimer 80 Parts Catalog – OEM Factory Specs for Mini Excavator covers a larger model in the same series. Ihimer 80VX 80NX3 Parts Catalog – Factory OEM Parts List and Ihimer 14NXT Parts Catalog – Factory OEM Specs follow the same layout. If you own multiple Ihimer machines, this family of catalogs will save you hours of cross-referencing.

For broader context on why factory documentation matters, see this Automotive Industry Overview. Same principle applies to construction equipment parts: traceability and accuracy are everything. Automotive Industry Overview won’t give you part numbers, but it explains why OEM supply chains are critical.

Is this catalog the same as a service manual?

No. It’s a parts catalog. It shows exploded diagrams and part numbers, not repair procedures. You still need a separate service manual for torque specs and disassembly steps.

Does it cover all serial number ranges?

Yes. Serial numbers WX000001 and WX100001 onward. If your machine is older than that, check with Ihimer for superseding parts. The catalog notes interchangeability codes for older and newer parts.

How do I use the interchangeability codes?

Look at the example on page 3: “0750 729 UA Change from part shown at the top to part shown below.” If your old part number is superseded, the catalog shows the new number and whether it’s interchangeable. If it says “not interchangeable,” you must order the new part and possibly modify the mount.

Can I order parts directly from this catalog?

You use the catalog to identify the part number, then order from an Ihimer dealer following the instructions on page 3. Provide machinery name, machinery number, parts number, parts name, and quantity. The catalog itself does not process orders.

You need a parts catalog that doesn’t waste your time with vague drawings. Access the Factory Manual – that’s the PDF you print once and keep in the shop binder. No reprints, no third-party copies. 182 pages of factory-sourced diagrams and part numbers. Every time you rebuild a swing drive or replace a hydraulic line on a 15NX2, you’ll have the exact reference. That’s what keeps a job moving and a customer happy.
