Ihimer 15J Parts Catalog

If you’ve ever ordered a part for an Ihimer 15J mini excavator using an aftermarket website and ended up with the wrong seal kit or a mislabeled hydraulic hose, you know the problem. Aftermarket parts catalogs guess. They copy diagrams from other machines, miss revision letters, and leave out the sheet numbers that tie a part to its exact assembly. This Parts Catalog from IHI Construction Machinery eliminates that. It’s the same binder the dealer parts counter uses. 243 pages of OEM exploded views with part numbers, quantities, and reference notes. No guessing. No wasted time cross-referencing three different databases.

Ihimer 15J Parts Catalog – What’s Inside

Open to any section and you get a clean exploded diagram with numbered balloons and a corresponding table. Every part has an IHI part number, description, quantity per machine, and any special notes. The catalog covers serial numbers BA001001 and up. That means it matches the late-model 15J machines you are most likely working on. Sections start with the lower machine and work all the way to the blade attachment and special parts. No reprints from other catalogs – this is the factory print, PUB No.5.

Lower Machine Breakdown – Crawler Shoes, Rollers, and Idlers

Track undercarriage parts wear out fastest. The catalog gives you six separate sheets just for the lower machine: crawler shoe assembly (sheet 1-2), front idler (1-4), lower roller (1-5), and the track adjuster device (1-3). Each sheet lists every bolt, shim, and seal. If you need the specific roller that matches the 15J’s track width, you find it on page 10 under sheet 1-5. No need to measure and guess – the part number is right there.

Hydraulic Instrument Coverage: Pumps, Motors, and Cylinders

This is where most people get burned. The 15J uses multiple traction motor variants (5-1, 5-1A, 5-1B) and two swing motor assemblies. The catalog breaks out each variant on separate sheets. The gear pump assembly has its own sheet (5-9), and there are two versions – standard and 5-9A. If you order a seal kit for the wrong revision, you waste a day. Page 62 has the standard gear pump; page 63-1 has the alternate. Same attention applies to the boom cylinder, arm cylinder, bucket cylinder, and blade cylinder – each with sub-variant sheets.

12 Major Sections from Chassis to Cab

The Table of Contents shows twelve numbered sections plus a Special Parts section (15). Sections include LOWER MACHINE, TURNTABLE, SWING DRIVE, HYDRAULIC PIPING, HYDRAULIC INSTRUMENT, OPERATING CONTROLS, POWER UNIT, CAB & RELATED PARTS, ELECTRIC SYSTEM, TOOLS & ACCESSORIES, HOE ATTACHMENT, BLADE ATTACHMENT, and SPECIAL PARTS. That is factory-level detail. The Cab section even has separate canopy sheets for TOPS models (8-3A) and nameplates in six languages. If you need the noise absorbent assembly, it’s sheet 8-2 on page 112.

Why Does OEM Documentation Matter for the 15J?

Aftermarket catalogs often merge parts from different serial number breaks. That leads to return loops and downtime. OEM documentation from IHI – the same source as the original machine – guarantees every part number matches the engineering release. The index (page 3-5) lists every sheet number and the exact page where the diagram lives. You can hand that page to a dealer or a supplier and they get you the right part on the first call. No need to explain “my machine is like a 15J but with…” – the catalog already shows the exact variant.

Using This Catalog for Fast Ordering

Flip to the Parts Index at the back of the catalog. Every part number is listed alphabetically with a cross-reference to the sheet it appears on. That saves you from flipping through 243 pages blindly. For example, if you need the boom swing cylinder, the index sends you to sheet 5-13 or 5-13A depending on your machine’s build date. The catalog also includes the HOE ATTACHMENT section (11) with separate piping and bucket assemblies. If you run a blade-equipped machine, section 12 covers the blade assembly and its piping.

Frequently Asked Questions

Does this catalog include exploded diagrams for every assembly?

Yes, every assembly page has an exploded view with part callouts.

How do I identify the correct part number for the hydraulic pump?

Each assembly sheet lists the part number, description, quantity, and notes. For example, in the Hydraulic Instrument section, the traction motor assembly (sheet 5-1) shows the motor, seals, washers, and bolts. You match the reference number on the diagram to the table. If you need a replacement gear pump, go to sheet 5-9 (page 62) and find the part number starting with the IHI prefix. Cross-check with your machine’s serial number BA001001 and above for this catalog. The index at the back also lists every part alphabetically so you can locate it in seconds.
