Iseki SG15H, 48C, 48E20, 48E20S, 48E40 Parts Catalog

I’ve seen too many Saturday mechanics pull the wrong part off the shelf because they guessed at the number. That’s money down the drain and a job stalled. This Iseki SG15H, 48C, 48E20, 48E20S, 48E40 Parts Catalog stops that. It’s 174 pages of factory-issued part codes and exploded diagrams. No cross-referencing from a Chilton’s or a sticker on an eBay box. You get the exact OEM number the assembly line used.

Iseki SG15H Parts Catalog: 7 Model Variants Included

This catalog covers the SG15H chassis with seven destination-specific variants: 48C (Japan), 48E20 (Germany), 48E20S (Germany), 48E40 (UK), plus the 48E40S, 48E50, 48E50S, 48RE240, and more. If your machine is one of these, the part code you need is listed. Each variant may use different filters, gaskets, or hydraulics – this catalog separates them by column.

Decoding the Parts List: How to Use the Diagrams

Page 2 of the catalog lays out the system. Each diagram has key numbers, part codes, quantities, and interchangeability symbols. You’ll see notations like ‘V’ and ‘W’ for standard market parts. The column marked ‘ITC’ tells you if a new part supersedes an old one. Pay attention to the symbols: * for standard, T for optional, R for replacement. That saves you from ordering a part that won’t fit your build date.

Why OEM Part Numbers Beat Aftermarket Cross-References

I won’t name names, but aftermarket catalogs often combine several years into one line. That’s how you end up with a filter that threads on but bypasses the internal bypass. OEM part numbers from this catalog are exact for your SG15H with its specific serial number range. The catalog includes the serial number breaks – rows show first and last serial. Use that to verify compatibility. If you have a related model, check the ISEKI SG17H Parts Catalogue Lawn & Garden Tractor for its specific parts.

Who Needs This Catalog? (Hint: It’s Not Just Mechanics)

If you own an Iseki lawn & garden tractor and plan to keep it running for the next decade, you need this. Dealers often want the part number before they’ll order anything. With this catalog in hand, you call them with the 13-digit code from the exploded diagram. Also useful for salvage yards when hunting used parts – you can verify what you’re pulling matches your engine and destination code. The Iseki SG153H, 48E20, 48E20S, 48E40, SG153H-E20S Parts Catalog covers a similar platform.

174 Pages of Factory Specs: What You Get

Pages 1 through 174 include the full parts breakdown for every major assembly: engine, transmission, steering, hydraulics, electrical, body panels, and more. The OCR sample shows suction filter assemblies with O-rings and part codes for 48E variants. Every hydraulic hose, bolt, nut, and bushing is listed with its quantity per machine. For example, the suction filter assembly for 48E variants uses a specific O-ring part number that differs from the 48C. Without this catalog, you’d likely order the wrong O-ring and end up with an air leak. Similarly, the hydraulic pump on the SG15H has a specific bolt part number and washer size – this catalog gives you that. Even the colour codes for painted panels are shown for your specific model, so you can order the correct touch-up paint. Factory data stops guesswork. For larger tractors, see the Iseki TS3110 Parts Catalog – Factory OEM Parts Breakdown.

Source Authenticity: Factory Original Print

This is a direct scan of the original ISEKI Parts Catalogue, not a rekeyed copy from some third-party. The file name is ISEKI_SG15H-48C… Parts Catalog_en-19214018919.pdf. That means it came from the factory. The notations match what you’d see in a dealer’s printed binder. I’ve seen the difference between factory and aftermarket parts books – aftermarket books skip the interchangeability codes and serial breaks. This one has it all. If you’re interested in how these tractors fit into the larger picture, you can read the Automotive Industry Overview on Wikipedia. The Automotive Industry Overview article provides context on manufacturing standards.

Does this parts catalog include torque specifications?

No, this is a parts catalog, not a service manual. Torque specs are in the service manual.

How do I find the part number for my specific model?

Use the table on page 2 to identify your destination code (e.g., 48C, 48E20). Then locate the assembly diagram for your variant. The part number is listed under the matching column.

Is this a reprint or a copy of an original?

This is a direct digital scan of the original factory Iseki parts catalogue. You get the same page layouts, part codes, and diagrams that dealers used.
