Iseki SF303, SF333 2003 Parts Catalog

If you’ve ever ordered a part for an Iseki tractor from an aftermarket source only to find it doesn’t fit, you know the waste. Time, money, and a tractor sitting dead. That’s why you need the Iseki SF303, SF333 2003 Parts Catalog – the factory document, not a scan someone ran through OCR and called good. I’ve been wrenching for 28 years and I can tell you: nothing kills a job faster than a wrong part number.

204 Pages of Factory Parts Breakdown

This catalog runs 204 pages and covers the SF303 and SF333 tractors – that includes SF303FH-UWE4M, UXE4M, UXWE4M and SF333FH-UWE4M, UXE4M, UXWE4M variants. Every component and option part is listed. The book was printed in Japan, February 2003. You get the exact same diagrams and part numbers the dealer uses. No guesswork about whether a hydraulic fitting is left-hand thread or right.

Does This Parts Catalog Cover Both SF303 and SF333 Models?

It covers both, and it distinguishes the engines: SF303 uses the E3CE-G engine, SF333 uses the E3CD-G. The catalog marks parts by model code letters – U for power steering, W for 2WD/4WD manual shift, X for automatic shift with permanent 4WD, E4 for Europe, M for illustrated labels. If your tractor has a combination like UXE4M, you’ll find the right diagram.

Decode the Part Numbers Using the Factory Notation

Page 2 explains the numbering system. Parts that begin with ‘V’ or ‘W’ are standard market parts. The ‘SPC’ column uses symbols: * means standard, T means optional, R means replacement. The ‘QTY’ column shows quantity per unit, with M for meter length, care for liters, AR for adjust-as-required. Serial number breaks are given – for example, ‘229’ means up to serial 229, ‘230–’ means serial 230 and later. You don’t have to guess; the factory already did the work.

Interchangeability Information: What You Need to Know

Page 3 lays out the interchangeability codes. An arrow with OLD→NEW means the new part supersedes the old. A 2 with arrow means old can replace new. A 3 with double arrow means they cannot be swapped. This is the kind of data aftermarket catalogs skip. If you try to substitute a part without this info, you risk a leak or a breakage at 1800 RPM. Use the factory chart.

7 Key Symbols You Must Understand

Beyond SPC and ITC, the catalog uses color codes (COL) for painted parts, and GRP for set replacements – for example, parts marked A can be replaced by B, etc. The remarks column links to other figures when a component is part of a larger assembly. This isn’t a simple parts list; it’s a complete identification system. For the full chassis breakdown, check the Iseki SF303/SF333 Chassis Parts Catalogue. And if you need engine service procedures, the ISEKI SF303 SF333 Front Mowers Service Manual – Section: Chapter 3. Engine Acces is your next step. For a different model, see the Iseki TS3110 Parts Catalog – Factory OEM Parts Breakdown.

The automotive industry as a whole – read the Automotive Industry Overview – relies on original equipment documentation. Getting a non-OEM parts catalog for a tractor this specific is a risk I wouldn’t take. Even the Wikipedia Automotive Industry Overview notes that standardization starts at the manufacturer.

Is this a reprint or a factory original?

It’s an authentic OEM scan of the 2003 factory print, 204 pages.

How do I order parts using this catalog?

First, locate the figure number (called ‘KEY’ in the manual) for your assembly. Read the part number from the illustration. Check the SPC symbol – if it’s marked T (optional) or R (replacement), make sure your tractor configuration matches. Then look up the interchangeability code on page 3 to verify supersession. Write down the full part number (e.g., 1720-097-100-00). Then order from your dealer or online using that number. If the catalog shows a color code (e.g., 300-959-004-00 for Sunset Gray), verify your tractor’s paint before ordering.

No aftermarket PDF can give you that level of certainty. Access the Factory Manual and get the part right the first time.
