Iseki SF438FH, SF450FH Parts Catalog – Factory OEM Parts Breakdown

You have a tractor down. A customer needs a part. You pull up some aftermarket site, type in the model, and get three different part numbers that might be the same thing. Then you order the wrong one because the description says “case/upper” but the picture shows a completely different casting. That burns an hour and loses money. This factory Iseki SF438FH, SF450FH Parts Catalog fixes that problem. It’s the same book the dealership uses to pull parts off the shelf. 212 pages of OEM part numbers, color codes, interchangeability codes, and application data. Not a reprint of some third-party compilation. Original factory scan.

212 Pages of Factory Parts Data

The catalog is split by sections you’d expect from a tractor this size: engine, transmission, hydraulics, steering, electrical, PTO, and chassis. Every page is organized the same way—key number, part code, description, specification code, quantity, interchangeability indicator, color code, and remarks. The head paragraph on page 1 walks you through exactly how to read each column. For example, if a part has an asterisk under “SPC,” it’s standard equipment. If it has an “R,” it’s a replacement or optional part that supersedes the original. That distinction alone will keep you from ordering the wrong version.

The color code section on page 3 lists spray-type and drum paints with their factory part numbers. Need Summer White? Code 1300-958-001-10. Mirror Black? 1300-954-004-00. That kind of specificity saves a respray when the shade is off by a hair.

Directions for Use – Reading the Head Paragraph

The first three pages are the instructions for how to use the catalog. Pay attention. On page 1 they spell out the model type codes: FH for four-wheel drive, B for blower case, G for extra specs for local homologation. Area code E4 means Europe. If you are in North America, you may still have a tractor built for export with that code. The table of part codes uses keys like V and W to denote standard market parts. The interchangeability column (ITC) tells you if a new part replaces the old one, if the old can be used in place of the new, or if they are not interchangeable at all. That is the kind of info you do not get from aftermarket parts catalogs. They just list a number and hope it fits.

Why OEM Parts Documentation Beats Aftermarket

Aftermarket parts catalogs are often compiled by someone who never touched the tractor. They guess at supersessions, leave out color codes, and ignore serial number breaks. This factory catalog shows exact quantity per unit, meter or liter supplied parts marked with M or L, and “AR” for parts that need adjustment. The lower column under QTY gives the serial number range—for example, “-229” means up to serial 229, “230-” means 230 and after. You need that data to match a part to a specific machine. Skip it and you are gambling. The Automotive Industry Overview is broad, but for tractors, the same principle applies: use factory specs or waste time.

What This Catalog Covers – Engine, Transmission, and More

The catalog uses figure numbers to group parts. Each figure shows an exploded diagram with key numbers matching the parts list. You get the case upper and lower, pins, bolts, seals, gaskets—anything that bolts to the tractor. The GRP column indicates which parts can be replaced as a set (marked with circles and letters). That is handy when you need to order a complete overhaul gasket set or a bearing kit. The remarks column even cross-references other maker’s part codes and Fig. No. for assembly groups. So if you see a remark with another figure number, you can jump to that section to get the individual pieces of a subassembly.

Who Needs This Manual?

If you are a shop owner who keeps three Iseki tractors on the lot, or a mechanic who gets handed a pile of parts every Tuesday, you need this. DIYers who are restoring a SF438FH or SF450FH in their home garage—you need it too. The catalog is not for someone who just wants to change oil and filters. It is for anyone who has to order a hydraulic valve, a steering knuckle, or a PTO shaft and cannot afford to get the wrong one. The price of one wrong order pays for the manual ten times over.

Frequently Asked Questions

Does this parts catalog cover the SF438FH and SF450FH both together?

Yes. One catalog covers both models. The parts list includes columns specific to each model with asterisks indicating fitment. SF438FH and SF450FH share most parts, but some items differ by serial number range.

Are the diagrams clear or are they fuzzy scans?

They are clear. Original factory scans, not photocopies. Each figure is fully legible with part numbers readable at normal zoom.

How do I know if a part supersedes to a newer number?

Use the ITC column. If it shows “1” (OLD → NEW), the new part works in place of the old. If it shows “2” (OLD → NEW), the old works in place of the new. If it shows “3”, they are not interchangeable. That system stops you from ordering obsolete stock.

Does this include paint color codes for touch-ups?

Yes, page 3 lists the factory color codes for spray paints and drum paints. Colors like Summer White (1300-958-001-10) and Mirror Black (1300-954-004-00) are included with their part numbers.

You have the tractor number. You have the serial. Now stop guessing and get the right parts the first time. Access the Factory Manual. The Automotive Industry Overview is broad, but for Iseki tractors, this catalog is the difference between a job done and a job re-done.
