Ihimer 35JX Parts Catalog

You’re pulling a worn idler off the undercarriage and the part number’s worn off the casting. Grabbing a random aftermarket PDF from the internet gets you a blurry drawing with wrong reference numbers. That costs time and money. The Ihimer 35JX Parts Catalog is the OEM document straight from IHI Construction Machinery – 230 pages of factory exploded views and part numbers. No reprints, no third-party redraws. Every sheet number matches the original publication.

Lower Machine Assembly: Crawler Shoes and Rollers

The catalog opens with the lower machine – sections 1-1 through 1-17. You get the full undercarriage breakdown: crawler shoe assembly, adjustment device, front idler, lower and upper rollers, and the traction piping. Page 2 shows the first lower machine assembly drawing. Need the part for that crawler expansion cylinder? It’s on sheet 1-8. The exploded view separates every bolt, seal, and bushing so you can order exactly what’s missing. No guessing which roller fits – the drawing calls out each part with a reference number tied to the parts list.

Hydraulic Instrument: Motors, Valves, and Cylinders

Section 5 is the hydraulic instrument – 41 sheets covering traction motors, swing motor, rotary joint, control valve, remote control valve, boom cylinders, bucket cylinders, blade cylinder, and the multiple valve assemblies. If you’ve got a machine with the A・F change configuration, the manual includes dedicated sheets for that. The oil pump assembly appears on sheets 5-22 through 5-25. Every seal kit number is there. You will not find torque values – that’s the service manual’s job – but you will find the correct bearing and seal part numbers to get the machine back together.

3 Reasons to Choose OEM Documentation

Aftermarket parts catalogs often re-pin part numbers or drop hardware items like washers and circlips. Factory documents from IHI keep the exact numbering. Reason one: the exploded view matches your machine’s actual layout, not a generic version. Reason two: the sheet numbers and page references are consistent across all Ihimer manuals – if you also work on an Ihimer 80 Parts Catalog – OEM Factory Specs for Mini Excavator, the structure is identical. Reason three: you get revision history. The index (page 2 of the PDF) shows REV No.1, so you know you’re looking at a corrected edition.

Operating Controls and Engine Control Assemblies

Section 6 covers the operator station: traction lever, control lever with gate lock, blade and boom swing control, and the engine control assembly. The engine control section alone spans 12 sheets (6-12 through 6-21), including a dedicated subset for deceleration systems. If your 35JX has the decel option, you need those specific pages. The catalog clearly labels each variant – for example, “ENGINE CONTROL ASS’Y (FOR DECEL.)” on sheet 6-5A. No cross-referencing guesswork.

7 Systems Covered in This Catalog

Lower machine, turntable, swing drive device, hydraulic piping (4-1 through 4-15), hydraulic instrument, operating controls, and power unit. The hydraulic piping section alone covers return and suction, swing and traction, pump discharge and boom swing, plus four variants of control piping. The power unit section includes engine and accessories, air cleaner and muffler, oil pump drive device, and fuel tank with water sedimenter option. That’s every major system on the Ihimer 35JX mini excavator.

What This Catalog Is – and What It Isn’t

This is a parts catalog, not a service manual. It gives you the part numbers and exploded diagrams needed to order components. It does not contain step-by-step disassembly procedures, torque specs, or troubleshooting. If you need those, pair this catalog with the OEM service manual. But for ordering the right part the first time, this document is the definitive source. For industry standards on construction equipment documentation, see the Automotive Industry Overview. More on equipment classification can be found at Automotive Industry Overview.

Does this catalog include torque specs?

No. This is a parts catalog. It lists part numbers and exploded views. Torque specifications are not included.

Will it cover a 35JX with serial number BL000500?

Yes. The manual applies to all 35JX models from serial BL000001 onward. The index confirms coverage from that starting point.

What sections are included in the 230 pages?

The catalog contains seven main sections: Lower Machine (crawler shoes, rollers, idlers, expansion devices – 17 sheets), Turntable (2 sheets), Swing Drive (2 sheets), Hydraulic Piping (15 sheets covering return/suction, swing/traction, pump discharge, and multiple control piping configurations – A～D, A・B・G, A・F), Hydraulic Instrument (41 sheets including traction motor, swing motor, rotary joint, control valve, remote control valve, hydraulic oil tank, oil pump, all cylinders – boom, arm, bucket, blade, crawler expansion, slide arm – and multiple valve assemblies for three change variants), Operating Controls (21 sheets for traction lever, control lever/gate lock, blade/boom swing control, blade/crawler expansion shift lever, and engine control assemblies including deceleration versions), and Power Unit (engine/accessories, air cleaner/muffler, oil pump drive, fuel tank with optional water sedimenter). Each sheet is indexed with page numbers so you can jump directly to the assembly you need.

Can I use this to rebuild the swing motor?

The catalog shows the swing motor disassembled in an exploded view with callouts. You’ll get the part numbers for seals, bearings, and housings. For the rebuild procedure, you’ll want the IHI service manual.

You need the correct part numbers to keep that 35JX in the dirt. I’ve ordered enough wrong parts in my time – a cheap aftermarket catalog costs more in freight and downtime than the right OEM document.
