Ihimer 35J Parts Catalog – Factory OEM Parts Breakdown for Mini Excavator

If you are wrenching on an Ihimer 35J mini excavator and the part number on that worn-out spool valve is rubbed off, guesswork will cost you a week and a half of downtime. I’ve watched guys order the wrong idler three times because they trusted a generic parts list off some forum. That nonsense stops here. The Ihimer 35J Parts Catalog is straight from Ishikawajima Construction Machinery – IHI – not a reprint, not a scan of a scan. It is the original factory document, 298 pages of exploded diagrams and part numbers that match what came on the machine when it left the line.

This catalog goes section by section. Lower machine, turntable, swing drive, hydraulic piping, hydraulic instruments, operating controls – each with its own sheet numbers. Need to find the exact crawler shoe? Turn to sheet 1-2, page 4. The front idler assembly is on sheet 1-4, page 8. The book is indexed so you don’t waste time flipping through mismatched pages. I’ve had to bench-race with aftermarket catalogs that skip half the hardware; this one lists every nut, seal, and spacer.

Lower Machine Assembly – Track Gear and Rollers

Three sheets cover the lower machine assembly (1-1, 1-2, 1-3). Then you get the crawler shoe assembly, the adjustment device, the front idler, lower rollers, upper rollers, and the traction piping. Everything is broken out with reference numbers that tie directly to the parts list. Page 2 shows the complete lower machine breakdown with callouts for the track frame components. If you are rebuilding the undercarriage, you need this to match the roller flanges and idler brackets.

Hydraulic Piping – 40+ Sheets of Line Layouts

This is where most aftermarket catalogs fall flat. Section 4, Hydraulic Piping, runs from sheet 4-1 through 4-48. That covers return and suction piping, swing and traction piping, pump discharge and boom swing piping, control piping with multiple changeover variants (A–D, A·B·G, short lever, A·F), and traction shift piping. Page 26 shows the return and suction piping assembly – all o-ring sizes and tube bends drawn out. If you are replacing a leaky hose assembly, you need the exact part number from this section, not a generic length.

Swing Drive and Turntable – Factory Specs for Bearing Replacement

The turntable and swing bearing assembly is covered on section 2, sheets 2-1 and 2-2. Swing drive device is section 3, two sheets on page 22. When the swing bearing starts making noise, you need the factory part number for the bearing and the bolt pattern. This catalog gives you the exact numbers so you don’t end up with a bearing that’s 10 mm too thick.

Who Needs This Manual and Why It Works

Home garage guys who do their own track work will save money by ordering the right parts the first time. Professional mechanics will keep the machine in the bay instead of waiting for wrong shipments. The manual works because it was written by the engineers who designed the 35J – not by someone copying from a third-party database. If you have ever tried to match a hydraulic motor seal using a caliper and a prayer, you know what I mean. This catalog eliminates the prayer.

Source Validity – OEM vs. Aftermarket Catalogs

I will say it bluntly: aftermarket parts catalogs are garbage for anything beyond a generic filter cross-reference. They omit revision levels, leave out the changeover variants (like the control piping for short lever or A·F change), and often list superceded numbers without telling you. This Ihimer 35J Parts Catalog is published by IHI, with revision number 4 on the index. It covers serial numbers from AD006001 onward. That matters because IHI updated the control valve and piping layouts after certain serial breaks. The OEM catalog accounts for those breaks. The aftermarket ones do not. For more on why OEM documentation matters in the automotive industry, see the Automotive Industry Overview. And yes, the same reasoning applies to construction equipment.

Frequently Asked Questions

Does this catalog include torque specs for the swing drive?

It is a parts catalog, not a service manual. Torque values are not included. You need the factory service manual for assembly specs. The parts catalog gives you the correct bolts and washers so you can then look up the torque spec elsewhere. Do not guess torque on a swing drive – I’ve seen what happens when somebody uses a 3/4 impact on a M10 bolt.

Will this work for an Ihimer 80 model?

No. This catalog is for the 35J only. The 80 model uses different undercarriage and hydraulic components. Look for the Ihimer 80 Parts Catalog – OEM Factory Specs for Mini Excavator and the Ihimer 80VX 80NX3 Parts Catalog – Factory OEM Parts List for those machines.

Are part numbers still available from IHI?

Many of these numbers are current. IHI still supports the 35J through their dealer network. The catalog gives you the number, then you order from your local IHI dealer. Call with the serial number – AD006001 or later – and the sheet number. Speeds up the counter guy.

How many pages does this manual have?

298 pages.

If you are tired of ordering parts by eyeballing diagrams and crossing your fingers, this is the fix. The IHI 35J Parts Catalog is the same book that sits on the parts counter at an IHI dealer.
