Iseki TMG18, TF15, TF17, TF12 Parts Catalog – Factory OEM, Not Aftermarket Guesswork

I’ve seen it a hundred times – a tech orders a part from an aftermarket catalog, it doesn’t fit, the customer waits another week, and you eat the return shipping. That’s why I won’t touch anything except the original factory parts catalog. This Iseki TMG18, TF15, TF17, TF12 Parts Catalog is exactly what the dealer’s parts counter uses. 220 pages, no shortcuts, no reprints. You open the PDF, find the figure number, read the key code, and order the exact part Iseki stamped. Period.

3 Reasons to Use a Factory Parts Catalog

First reason: part numbers you can trust. The aftermarket catalogs on eBay? They transpose digits, omit superseded parts, and show illustrations that belong to a different model. This catalog lists every part with a key number, description, quantity, and what type of machine it fits. Second reason: the interchangeability (ITC) codes. Page 2 of the manual explains OLD ← NEW, OLD → NEW, and OLD ← NEW. That tells you if a new part replaces an old one or vice versa. Third reason: color codes for painted parts. When you need a new fender or hood, you order the right spray paint by code – 4 G Crystal Blue, 5 I Sunset Gray, etc. That saves you from painting a tractor that looks like a checkerboard.

Understanding the Parts Catalogue Symbols

The OCR excerpt I’m looking at shows the head paragraph: key, part code, description, q’ty, type of model, and remarks. The symbol * means standard part. T means optional. R means applicable replacement. The serial number columns tell you which production range the part fits. If your TMG18 has serial number 1500 and the part is listed for 1–1999, you’re fine. If it’s listed only for 2000–, you need a different part. That level of detail keeps you from ordering the wrong hydraulic filter – like the suction filter assembly on figure 164, part 126, part number 1814-508-200-00. Without this catalog, you’d be guessing.

Applicable Machines: TMG18, TF15, TF17, TF12

This catalog covers four models. The note at the top of page 1 explains the suffixes: H for HST, S for independent PTO clutch, V for aux valve, M for mid PTO, U for power steering, and E42 for Europe/Oceania turf type. If you own a TF15 with power steering and a mid PTO, you look for the U and M columns in the table. The part you need will have an asterisk or a serial number range in those columns. Iseki designed this so a dealer parts guy can find the right part in under a minute. You can do the same.

Color Codes and Paint Specifications

Welding a new sheet metal panel is pointless if you can’t match the paint. This catalog dedicates a full section to color codes. The table lists code 4 G Crystal Blue, 5 I Sunset Gray, 6 G Summer White, 7 F Mirror Black, and 8 F Brilliant Brown Metallic. Each color has a spray-type paint code and a drum paint code. If you need to order a 4K drum of Crystal Blue, the part number is 1300-957-003-00. That’s factory data you won’t find in any generic manual. And don’t forget the note: color code is signified only for parts assigned by the maker as color parts – so don’t waste money painting a black plastic trim piece.

Serial Numbers: Where to Find Them

Page 3 shows the serial number location for the engine. For the tractor itself, the serial number is stamped on the transmission case – usually on a flat pad near the PTO housing. The catalog uses these numbers to narrow down which parts apply. If you skip this step, you might order a clutch filter that fits only later production models. I’ve seen a shop order three filters before they checked the serial number. Don’t be that guy.

Interchangeability (ITC) Codes: When Parts Swap

The ITC codes on page 2 tell you whether you can substitute an old part with a new one. Three cases: 1) OLD ← NEW means new replaces old – buy the new part. 2) OLD → NEW means old replaces new – if you have a new part, it won’t work; you need the old. 3) OLD ← NEW means no interchange – you must get the exact number. That’s critical for things like the suction filter or the O-ring (part VT21-103-103-50). One wrong O-ring and you’re draining fluid again.

Does this manual cover TF18 models?

No, it covers TMG18, TF15, TF17, and TF12 only. For TF18, see the related manual linked above.

Is this a scanned PDF or a reprint?

It’s a direct digital copy of the factory original. 220 pages, no missing pages, no added watermarks. It is not a third-party recreation.

How do I find the correct part number for my TMG18 with HST transmission?

Look for the H column in the table. If the part has an asterisk in that column, it’s standard for HST. If it shows a serial number range, match your tractor’s serial to that range. The catalog also lists optional parts with a T symbol – those require a separate order.

What if the part number in the catalog is superseded?

The ITC code on page 2 will tell you. If the code is OLD ← NEW, the new number replaces the old. If it’s OLD ← NEW (no interchange), you must use the exact number listed. Always check ITC before ordering – I’ve seen guys order a part that was superseded twice and still didn’t fit.

You’ve got a tractor that needs parts. You can waste time cross-referencing three different websites, or you can open this catalog and source the exact component Iseki intended. Access the Factory Manual and stop relying on hearsay. Your TF12, TMG18, TF15, or TF17 will thank you the next time you don’t have to reorder a filter.
