Ihimer 25J Parts Catalog

If you’re wrenching on an Ihimer 25J mini excavator and you’ve ever ordered a part that didn’t fit, you know the frustration. That’s why you need the factory parts catalog – not a scanned copy from someone’s garage, but the actual Ihimer 25J Parts Catalog from Ishikawajima Construction Machinery. This isn’t a repair manual; it’s the parts bible. Every nut, seal, and hose assembly is broken down on the page so you can cross-reference serial numbers and get the right component the first time.

What’s Inside the Ihimer 25J Parts Catalog

This OEM document runs 277 pages and covers every major system on the 25J. The table of contents is laid out with sheet numbers and page references. You get exploded diagrams for the lower machine (crawler shoe assembly, front idler, lower roller, traction piping), turntable and swing bearing, swing drive device, and a deep dive into hydraulic piping with sections for return/suction, swing/traction, pump discharge/boom swing, and multiple control piping variants (including short lever and CE versions). The hydraulic instrument section alone runs from traction motor to boom swing cylinder, with parts for control valves, remote control valves, solenoid valves, and cylinders. Power unit has engine accessories, air cleaner, fuel tank with optional water sedimenter. Cab and related parts cover canopy, operator seat, name plates, electric system. Hoe attachment and blade attachment are detailed, plus a full options section with spare port piping, operator room, car heater, defroster, and lighting assemblies. A complete parts index ties it all together.

277 Pages of Exploded Views

Each assembly is shown as an exploded view with callout numbers that match the parts list. You get factory part numbers, quantities per machine, and sometimes notes on superseded parts. For example, the lower machine assembly (sheet 1-1) shows every track roller, idler, and shoe component. The crawler shoe adjuster device (sheet 1-3) lists the tension spring, yoke, and shims. If you need to rebuild the swing drive (sheet 3-1), the diagram includes the motor, brake, and reduction gear parts. This catalog doesn’t waste space on theory – it’s pure parts identification.

Does This Cover Hoe Attachments?

Yes. Section 11 is dedicated to the hoe attachment assembly, boom swing, hoe bucket, and the full piping setup. Sheet 11-1 shows the main hoe frame and linkage pins. There’s also a separate blade attachment section (section 12) with blade cylinder and piping. If your machine has optional modifications like spare port piping or a cabin with heater (section 15), those are included too. The catalog covers serial numbers from AH003501 onward, so verify your machine’s serial before ordering.

Find the Right Part Number Fast

Use the printed parts index at the back of the catalog. Every part number is listed alphabetically or numerically depending on the section. Cross-reference the exploded view sheet number on the page header. For example, if you need a swing motor seal kit, go to sheet 5-2 (swing motor assembly) and find the part number for the shaft seal. Then verify it against the optional CE variants if applicable. This is the same system dealerships use – no guesswork.

Hydraulic Piping: Detailed Breakdown

The hydraulic piping section (section 4) is split into five sub-sections: return/suction, swing/traction, pump discharge/boom swing, control piping (standard, A~D change, short lever, short lever CE). Each sub-section has its own exploded diagram with hose routing and fitting part numbers. If you’re replacing a damaged hose or adding a third-function valve, you can see exactly which adapter fittings and O-rings are needed. The control valve assembly (sheet 5-4) shows the main spool sections and their part numbers, including the optional multiple valve assemblies (sheet 5-14 and 5-14A for A~D and A·B·G changes).

Why a Factory Parts Catalog Beats Aftermarket Lists

I’ve seen too many techs order a “universal” track shoe or a “standard” hydraulic fitting that doesn’t match the bore or thread pitch. Aftermarket catalogs often skip the nuance of serial-number breaks and regional variants (CE vs non-CE, short lever vs standard). This OEM catalog documents every change – notice the sheet numbers with letters like 4-4A, 4-4B, 4-4C. Those are real production variants. Ignore them and you’ll waste a week waiting for the wrong part. The original Ishikawajima print also uses metric thread designations and Japanese part numbering that matches the factory inventory. If you want to keep your 25J running without downtime, start here.

What serial numbers does this catalog cover?

It covers Ihimer 25J machines from serial number AH003501 onward. Lower serial numbers may have different part numbers – verify your machine’s serial before ordering.

Does this include torque specifications or repair procedures?

No. This is a parts catalog – it shows exploded views, part numbers, and quantities. For assembly torque values and service steps you need the factory service manual. Do not use this catalog as a repair guide.

Can I use these part numbers at any dealer?

Yes. The part numbers are factory IHI numbers used worldwide. Some regional distributors may cross-reference to their own inventory, but the base number is the same. The catalog also lists optional parts for CE, Italian, French, and German machine variants.

Is the catalog in English?

The index and section headings are bilingual English/Japanese. Part callout tables use English descriptions for the main components. You don’t need to read Japanese to use it. The diagrams are self-explanatory with clearly numbered callouts.
