Iseki SG153H, 48E20, 48E20S, 48E40, SG153H-E20S Parts Catalog

Ordering the wrong part because you guessed the model suffix or ignored the color code is a waste of a Saturday and your wallet. I’ve seen guys pull a filter off a shelf, compare it to a blurry photo, and still get it wrong. That’s why an OEM parts catalog — like this Iseki SG153H, 48E20, 48E20S, 48E40, SG153H-E20S Parts Catalog — exists. 161 pages of exploded views, part numbers, and the exact symbols that tell you if a part is standard, optional, or a replacement. No aftermarket translation. No guesswork.

Parts Catalog Coverage for the SG153H Line

This catalog covers the SG153H, SG153H-E20S, 48E20, 48E20S, 48E40, 48E40S, 48E50, 48E50S, 48E50T, 48RE40, and 48RE40S models. Page 1 lists them all. Each model variant has specific parts — the E20 suffix means Germany, E40 means UK & Oceania, E50 means France, E50T Italy. If you’re working on an SG153H-E20S and order a part meant for a standard SG153H, it may not fit. This catalog breaks down every nut, bolt, filter, and seal by model code. Check the QTY column; ‘M’ means sold by the meter, ‘l’ by liter, ‘AR’ means adjust as needed. Don’t skip that detail.

What Makes This OEM Catalog Different?

Aftermarket parts catalogs often copy the diagram but leave out the interchangeability codes (ITC) and color references. Page 2 of this Iseki catalog gives you the full ITC system: 1 means old part can be replaced by new, 2 means they interchange both ways, 3 means they don’t swap at all. You also get color codes — Crystal Blue (4G), Summer White (6G), Mirror Black (7F), Silver Mist (8E) — with actual paint and spray can part numbers. That’s the difference between a part that blends in and one that stands out like a sore thumb.

161 Pages of Exploded Views and Part Numbers

Every assembly is drawn with a key number linking to a table of part codes. The manual uses Fig. numbers — for example, a filter assembly shows up under key 126 (part code 1614-508-200-00) and key 128 (1614-508-260-00). You get the exact Iseki factory number, not a generic cross-reference. 161 pages, no filler. If you need to rebuild a hydrostatic drive or replace a mower deck spindle, the exploded view tells you what goes where and what part to order. ISEKI SG153H Parts Catalogue Directions for Use explains the symbol table in more detail.

Understanding the Symbol System: *, T, R

Page 2 of this catalog defines three symbols. Asterisk (*) means the part is standard equipment. T means the part is optional — it may not be installed from the factory. R means the part is an applicable replacement for an originally equipped part. If you see ‘R’ on a hydraulic filter, you can use it as a direct swap. These symbols are printed next to each part in the QTY column. Ignore them and you might order an optional part that doesn’t fit your machine. Iseki SG15H Lawn & Garden Tractor Parts Catalogue is a related manual for a smaller frame, but the symbol logic is the same.

Color Codes and Paint Reference

The catalog dedicates a section to color codes for body and trim parts. Each color is assigned a code number and a paint part number for spray, 4K drum, and 16K drum sizes. For example, Summer White (6G) spray paint is 1300-958-001-00. If you’re restoring a 48E40 for a customer, you want the exact shade, not a rattle-can approximation. The manual notes that color codes are only specified for parts that require paint. No guesswork.

Get the Right Part the First Time

Before you call your supplier, have the model number, the key number from the diagram, and the part code from this catalog. The SG153H and 48E series share many components, but the suffix determines specifics like exhaust configuration and wiring harness. ISEKI SG17H Parts Catalogue Lawn & Garden Tractor covers a related platform, but for the SG153H line, use this one.

Does this catalog include engine parts?

Yes, all engine components are listed with exploded views.

How do I interpret the symbols in the parts list?

Page 2 of the manual defines each symbol. Asterisk (*) means standard equipment, T means optional, R means replacement. Also see the interchangeability codes (ITC) that tell you if old and new parts swap. Color codes for painted parts are listed with specific paint numbers. Follow the symbol table precisely — ordering an optional part (T) when you need a standard part (*) will leave you with the wrong item. The catalog also uses QTY notations: ‘M’ for meter, ‘l’ for liter, ‘AR’ for adjust-as-needed. These apply to cables, hoses, and hydraulic lines. Without reading the direction pages, you risk ordering a part sold by the meter when you only need 15 inches.
