Iseki TXG23, TXG23FH, TXG23TH, TXG23E 2003 Parts Catalog

You’ve got a tractor torn down to the block, a pile of bolts on the bench, and you’re staring at a part you swear came off the PTO housing—but the aftermarket diagram says it belongs to the steering column. That’s exactly why you need the factory Iseki TXG23, TXG23FH, TXG23TH, TXG23E 2003 Parts Catalog on your bench. Not a scanned reprint with blurry lines. Not a generic parts list lifted from a different model year. This is the original 222-page bound catalog printed in Japan, February 2003, covering every nut, seal, and hydraulic fitting for the TXG23 family.

I’ve seen guys burn three hours hunting a part number because the online database said “TXG23” but didn’t specify the FH versus TH driveline. The FH stands for four-wheel drive; the TH is two-wheel drive. Those use different front axles, different steering knuckles, different everything. This catalog keeps them straight. It also covers the TXG23E (Europe spec) with the VE4 remote control valve option. Iseki TXG23 Series Parts Catalog is the reference you reach for before you reach for the phone.

Parts Catalog Layout and Symbol Legend

Flip to page 2. You’ll see the “Directions for use of Parts Catalogue” section. I’ll summarize the critical bits. Each part diagram has a KEY number that links to the parts list. Part numbers starting with V or W are standard market parts—buy them from any Iseki dealer. Numbers starting with other prefixes are OEM-only. LH and RH are defined relative to the direction of travel, not your viewpoint sitting on the tractor. Get that wrong and you order a left-hand tie rod for the right side.

The SPC column uses symbols: asterisk (*) for standard parts, T for optional, R for replacement parts that supersede originals. That single letter tells you whether you can bolt in a newer version without modifying brackets. ISEKI TXG23 Service Manual gives you the removal procedure; this catalog gives you the exact replacement part.

222 Pages of Factory Part Numbers

Two hundred twenty-two pages. That’s not a skimpy pocket guide. That’s every assembly broken down into component parts: engine block, cylinder head, fuel injection pump, transmission case, front axle, rear differential, hydraulic system, wiring harness, steering gear, seat, fenders, even the decal set. Each figure is a real exploded-view drawing, not a cartoon. The quantity column tells you how many per machine—marked M for meter lengths of hose or cable, L for liter supplies, AR for adjust-as-required items (shims, washers). Upper row is the base quantity; lower row shows when the quantity changed based on the serial number break point. For example, the hydraulic filter part number changed after serial number 229. Without this catalog you’d order the wrong filter and wonder why the canister won’t seal.

What Do the ITC Codes Mean for Your Repair?

Page 3 explains interchangeability (ITC). Three codes: 1 – new part can replace old part (direct swap). 2 – old part can replace new part (backward compatible). 3 – no interchange, you cannot mix them. I’ve seen a mechanic ignore the ITC code, install a “new style” seal on an old bore, and the seal walked out in a week. The catalog marks which parts are part of a SET group (GRP column). If you see A in the GRP column, that part can be replaced by the set that covers parts B, C, D in sequence. Don’t buy individual pieces when the set saves you money and headaches.

Serial Numbers: Where to Find Them on Your TXG23

Before you order anything, note the serial number. The catalog tells you exactly where it’s stamped: engine serial on the cylinder block (Figure 5-1), chassis serial on the label. The serial number break determines which parts are used. For instance, the steering column assembly differs for early production (serial up to 229) versus later (serial 230 and up). The catalog shows both part numbers side by side. If you ignore the serial range, you’ll get the wrong column. ISEKI TXG23 Kompaktschlepper Operator’s Manual will show you how to locate the label if you’re new to the model.

Use the Color Code Table to Identify Original Parts

Page 3 includes a color list for painted components like the hood and fenders. The catalog lists color code numbers (e.g., NEO-BLUE, GRAY METALLIC, MIRROR BLACK). Factory paint codes match the color of the part as delivered. If you’re restoring a tractor or touching up a scratch, reference the color code from this catalog. Aftermarket spray cans seldom match without these numbers. The catalog also notes COL in the parts list when the color applies—no guessing if the part is supposed to be black or gray.

Parts Order: How to Get the Right Number

Page 4 covers ordering procedures. All part numbers are registered in the Iseki online computer system. When you order, double-check the number from this catalog. If a substitute part exists, the system automatically replaces the number. But you still need the correct base number to start. The catalog’s “Remarks” column sometimes shows a different maker’s part code—useful if you’re cross-referencing a local supplier. For example, a hydraulic O-ring may show a JIS standard number that any bearing house can match. Automotive Industry Overview covers why OEM specs matter for reliability; this catalog gives you those specs.

Four models. Two drive configurations. Multiple region codes. 222 pages of factory data. That’s what you get when you stop relying on aftermarket cross-reference sheets. The automotive industry as a whole depends on original equipment documentation—Automotive Industry Overview confirms that. For your Iseki, this catalog is the source.

Can I use this catalog to order parts for a TXG23E model?

Yes. The catalog includes all four variants: TXG23, TXG23FH, TXG23TH, and TXG23E. Area codes E4 (Europe) and E6 (Oceania) are listed, so European spec tractors with the remote valve are covered.

How do I interpret the part number prefixes V and W?

Parts starting with V or W are standard market parts available from any Iseki dealer. The catalog explains that these are common hardware or components that can be sourced through the normal supply chain, not rare factory-only items. For example, a bolt listed as V123456 can be ordered by that number at any Iseki parts counter. Prefixes other than V or W are exclusive to the OEM parts network and may require the full factory part number. Always verify the full part number against the diagram—catalog page 2 covers this.

You’ve got the knowledge. Now get the paper. Access the Factory Manual and put this 222-page parts catalog on your tablet or print it for the shop wall. No more parts counter arguments. No more guessing which seal fits which housing. This is the factory print.
