Iseki TH4260, TH4290, TH4330 2004 Parts Catalog – The Only Factory Document for Part Numbers

If you are wrenching on an Iseki TH4260, TH4290, or TH4330 tractor and you order a part by eye or by memory, you are burning billable hours. I have seen guys slap a gasket on one of these things from an aftermarket cross-reference and then wonder why the oil leaks run down the bellhousing. This is not a service manual – it is the Iseki TH4260, TH4290, TH4330 2004 Parts Catalog, 463 pages of factory part numbers, interchange codes, color codes, and model breakdowns. You get exactly what the assembly line used. No guesswork. No reprints. Original OEM print scanned from the 2004 release.

This catalog covers the TH4260F-DRE4/MDE4/MDRE4, TH4260FH-ME4/MRE4, TH4290F-DRE4/MDE4/MDRE4, TH4290FH-ME4/MRE4, and TH4330FH-ME4/MRE4. Every configuration – four-wheel drive, HST, mid PTO, double clutch, front/rear hitch and ROPS – is here. The model code is explained on page 2 of the PDF: F…FOUR WHEEL DRIVE, H…HST, M…MID PTO, D…DOUBLE CLUTCH, R…FRONT/REAR HITCH & ROPS. Area code E4 means Europe. If you are in North America, some part numbers may differ, but the base opus is identical. The bookmarks and OCR make searching quick. I keep this on my tablet in the shop.

TH4260, TH4290, TH4330 – What the Model Codes Mean

Before you call the dealer, decode the serial number plate. Page 4 tells you where to look: engine serial number stamped on the cylinder block (Fig. 5-1), chassis number on the label. Then cross-check the model suffix. A TH4330FH-ME4 is an HST mid-PTO model with front/rear hitch and ROPS. Order a clutch disc for a double-clutch variant and you will get the wrong diameter. The catalog divides lists by lower column serial number ranges – “-229” (up to serial 229) and “230-” (serial 230 and after). Miss that and the spline count will be off. I have seen it happen.

GPS-Level Part Numbering Across 463 Pages

Each part in this catalog is keyed to an illustration. The “KEY” column shows the location on the diagram. Part numbers that start with “V” or “W” are market standard parts – bolts, nuts, washers you can buy anywhere. The rest are Iseki-specific. The “SPC” column uses symbols: * for standard, T for optional, R for replacement. Quantity column shows units – “M” for meter, “l” for liter, “AR” for adjustment required. Upper row is quantity per machine, lower row is serial number cutoff. This level of detail is what you pay for when you access the factory manual instead of a third-party PDF.

3 Critical Sections for Ordering the Right Parts

First: the Interchangeability (ITC) codes on each page. Code 1 means old part can replace new. Code 2 means new can replace old. Code 3 means not interchangeable. If you ignore ITC, you will order a part that looks the same but breaks in 50 hours. Second: the Color Code (COL) column. Page 4 lists the color palette: Mirror Black (7F), Sunset Gray (5I), Neo Blue (4L), Summer White (6G). Paint codes come with spray and drum options – do not guess which shade matches the hood. Third: the SET/ASSY note in the Remarks column. When you see “Fig. No.” in remarks, that means component parts are listed in that figure. Do not buy an entire assembly when a $3 seal fails. That is how you waste money.

Interchangeability Codes and Color Matching

One thing that annoys me about aftermarket parts catalogs: they never tell you if a redesigned part fits backwards. Iseki marks ITC clearly: 1 = OLD → NEW (new part works on old machines), 2 = OLD → NEW (old part works on new), 3 = OLD → NEW (no swap). Page 3 explains this in the OCR. Also, the GRP column groups parts that can be replaced as a set – those marked ○ A can be replaced by ○ B, and ○ D for ○ C. If you are retrofitting a later-model part, you need to follow the alphabetical order. Do it wrong and the bolt holes won’t line up.

Why Aftermarket Parts Catalogs Fail This Tractor

Third-party sites throw generic diagrams at you and call it a day. They skip the SPC symbols, the color codes, the serial number splits. I had a customer bring in a TH4290 that had been “rebuilt” with a clutch from a TH4260 because the parts house said they were the same. The pilot bearing was different. Downtime: two weeks. With this 463-page factory catalog, you look at the correct model variant, check the ITC code, verify the serial number range, and order the exact part. That is why I buy only OEM documentation from ISEKI TH4260/TH4290/TH4330 Parts Catalog. If you also need the chassis-specific breakdown, get Iseki TH4260/TH4290/TH4330 Chassis Parts Catalog. For the full parts catalogue manual, ISEKI TH4260 TH4290 TH4330 Parts Catalogue Manual is the one.

For broader context on agricultural equipment documentation, you can read the Automotive Industry Overview. It is a decent background. But when you are on the shop floor with a tractor that won’t start because the wrong injector was ordered, you need the factory spec. Another reference point is the Automotive Industry Overview, but again – speculation doesn’t fix equipment. This parts catalog does.

Q: Does this catalog cover the TH4330FH with HST?

Yes. All model variants listed on the first page – TH4260F-DRE4, TH4260FH-ME4, TH4290F-DRE4, TH4290FH-ME4, TH4330FH-ME4, plus the corresponding MRE4 versions.

Q: How do I decode the interchangeability symbols on a part line?

Look at the ITC column. A “1” means the old part number can be replaced by the new one – the new part fits older machines. A “2” means you can use the old part on new machines. A “3” means they are not interchangeable – do not try. Also check the GRP column: if the part has a circle letter (○ A, ○ B), that indicates set replacement groups. Follow the alphabetical order: parts in group A can be replaced by parts in group B, etc. These codes prevent buying the wrong release bearing or hydraulic spool. I always scan the ITC column before ordering anything with a price tag over $20.

You have a choice. Keep flipping through aftermarket PDFs that list “compatible with” and hope the bolt hole distance matches. Or get the actual 2004 factory parts catalog that Iseki printed for their dealers. This is the real thing – 463 pages, original JPEGs, OCR searchable. No reprints, no third-party edits. Access the Factory Manual and stop ordering parts by guess.
