Iseki TH4260, TH4290, TH4330 Parts Catalog

If you’ve ever ordered a part for a tractor and gotten something that doesn’t fit, you know the pain. That box arrives, you pull the old part, and the new one is off by a hole pattern or a thread pitch. Then you’re down another week waiting for a return. This Iseki TH4260, TH4290, TH4330 Parts Catalog is exactly what you need to stop that cycle. It’s the same printed material the dealer uses – 342 pages of exploded diagrams, part numbers, and interchangeability codes. I’ve been wrenching for 28 years, and I can tell you: a factory parts catalog is the difference between a one-hour job and a three-day headache.

What This Parts Catalog Actually Covers

This isn’t a service manual. You won’t find torque specs or step-by-step repairs here. What you do get is the complete factory parts breakdown for the Iseki TH4260, TH4290, and TH4330 tractors. Every component from the HST transmission to the mid-PTO, the double clutch, the double spool valve, and the front/rear hitch with ROPS. The catalog breaks down by model type codes (F for 4WD, H for HST, M for mid-PTO, D for double clutch, W for double spool valve, R for hitch/ROPS) and area code E4 for Europe. That level of specificity means you order the exact part for your exact machine, not a cross-referenced guess.

Page 1 lays out the head paragraph explanation – how to read the key numbers, which parts are standard (V and W prefixes), and what LH/RH mean relative to machine direction. That page alone will save you from ordering a mirror-image bracket that won’t bolt up.

Interchangeability Codes (ITC) – Why They Matter

The catalog uses a three-code ITC system. Code 1 means old part supersedes to new – you can use the new number in place of old. Code 2 means old part replaces new – if you have the older number, it still works. Code 3 means no interchange – old and new are not compatible. I’ve seen guys order a “supercession” part without checking the ITC code, then wonder why the fuel filter doesn’t thread on. Page 2 explains this in plain English. Memorize those codes before you order anything.

Color Codes and Serial Number Locations

Page 3 lists the factory paint colors: Mirror Black (7F), Sunset Gray (5I), Neo Blue (4L), Summer White (6G), each with spray and drum parts codes. If you’re doing a restoration or a panel replacement, that saves a trip to the paint store mixing custom colors. The catalog also tells you exactly where to find the serial numbers: for the engine, it’s stamped on the cylinder block (see Fig. 5-1); for the chassis, it’s on the label. Use the serial number in the lower column of the parts list – it separates pre-229 and post-230 machines. A minor detail that can mean a different hydraulic pump or control valve.

Parts Ordering – How to Use This Manual

Every part number in this Parts Catalog is registered in the ISEKI online computer system. When you call a dealer, you need that 10-digit number, not the diagram reference. The manual gives you both – the Fig. No. and the part code. Key column numbers reference the illustration. Look for the letter indicators: * means standard part, T means option, R means replacement. There’s also an AR quantity for parts that need adjustment (like shims). And the GRP column shows which parts can be ordered as a set – marked by circled letters A, B, C, etc. That’s critical for ordering complete seal kits or bearing assemblies instead of piecing them out.

If you’re working on a TH4260 and need the engine mount set, flip to the engine group, find the Fig. No., and match the key number. Cross-reference the serial number range. Then call your supplier with the exact part number. No returns. No wasted downtime.

Audience: Who Needs a Factory Parts Catalog?

DIY owners of the TH4260, TH4290, or TH4330 who do their own maintenance. Small farm operators who can’t afford a wrong part. Dealer parts counter guys who want a printed backup to the online system. If you’re replacing a clutch, a PTO seal, or a steering cylinder, you need to see the assembly layout and the part numbers for every spring, snap ring, and o-ring. Aftermarket catalogs often group parts by generic category or skip the smaller components – this factory catalog doesn’t. 342 pages, every fastener called out.

One caveat: because this is a European-area (E4) catalog, some optional equipment may differ from North American spec machines. But the standard chassis and engine parts are identical. Check the model type suffix on your tractor’s serial plate. If it has HST (H code) or mid-PTO (M code), you’re covered.

Source Validity – OEM vs Aftermarket

This is a direct factory PDF from ISEKI – not a reprint, not a third-party compilation. I won’t use aftermarket parts catalogs myself because they mix up part numbers and miss revisions. The original file name ISEKI_TH4260-TH4290-TH4330_Parts_Catalog_en-19214019806.pdf tells you it came from the manufacturer. The interchangeability tables and color codes are from Japan, not guessed by a writer in an office. That matters when you’re trusting a hydraulic hose to hold 2500 psi.

Iseki TH4260, TH4290, TH4330 Parts Catalog – Factory OEM Document

If you are wrenching on an Iseki TH4260, TH4290, or TH4330 tractor and you need the right part number the first time, this is the document you want on your bench. Aftermarket parts catalogs are a guessing game – somebody transposes a digit, and you end up with a clutch plate that does not fit. That costs time and money. This PDF is a direct scan of the factory Iseki Parts Catalog, 459 pages of genuine part codes, interchangeability codes (ITC), color codes, and serial number breaks. No reorganizing, no corporate rebrand. Just the OEM data.

What This Parts Catalog Covers

This document lists every component and option part used for the TH4260, TH4290, and TH4330. It covers four-wheel drive (F) and HST (H) variants, mid PTO (M), double clutch (D), and front/rear hitch with ROPS (R). The area code is E4 for Europe, but the part numbers work for any market because Iseki used the same base catalog across regions. You will find separate columns for model types like SSM48M, SSM48F, SSM48G, SRM48M, SRM48F, and SRM48G. Each row shows the part code, description, quantity per unit, and serial number range. This is not a service manual – Iseki TH4260, TH4290, TH4330 Parts Catalog is a parts identification tool. If you need disassembly steps, grab the service manual from Iseki TH4260, TH4290, TH4330 Service Manual – 248 Pages.

How to Read the Parts List

Open to page 1. You see a table with KEY, PART CODE, DESCRIPTION, SPC, and columns for each machine type. The KEY number matches the illustration – find the part in the drawing, then read across. Part codes starting with ‘V’ or ‘W’ are standard market parts; you can source them from any Iseki dealer. The SPC column uses asterisks for standard parts, ‘T’ for optional, and ‘R’ for replacement applicable parts. Below the quantity, there is a serial number: for example, ‘-229’ means up to serial number 229, while ‘230-‘ means from 230 onward. Get that wrong and you order the wrong filter bracket. The ITC column tells interchangeability: ‘1’ means new part replaces old, ‘2’ means old can replace new, ‘3’ means they are not interchangeable. Pay attention to that – I have seen guys bolt on a ‘3’ part and ruin a hydraulic housing.

Color Codes and Options: What Each Marking Means

Page 3 of the catalog includes a color list. Colored parts (like plastic shrouds or emblem decals) have a color code number next to the part code. The manual gives a color list – you need that when ordering a replacement hood that matches the original paint. Also note the GRP column: parts marked with the same letter can be replaced as a set. For example, if the parts diagram shows ‘A’ under GRP, and you have ‘A’ on another part, they are a set. Do not mix and match when the factory says to replace as a group. I have seen that cause vibration in three-point hitches. For the full parts breakdown, also see Iseki TH4260 TH4290 TH4330 2014 Parts Catalog – OEM Factory Manual and Iseki TH4260 TH4290 TH4330 Parts Catalog – OEM Factory Manual – these are the same catalog under slightly different filenames; we carry the genuine version.

Who Needs This Catalog

If you own a TH4260, TH4290, or TH4330 and do your own repairs, you need this. The average shop labor rate in San Antonio is $120 an hour. One misordered part costs you shipping, restocking fees, and lost time. This catalog saves you that. Beginners – do not be afraid of the tables. The translation is rough (the original PDF is from Iseki’s Japan office), but the part numbers and codes are exact. If you can match a KEY number to an illustration, you can order the right part. Professionals – you already know that OEM catalogs beat aftermarket parts databases because aftermarket databases often skip serial number breaks. Use this to cross-reference. The Automotive Industry Overview on Wikipedia shows why OEM documentation matters for traceability – same principle applies to farm tractors.

459 Pages of OEM Data

This is not a reprint from a third-party aggregator. This is the original factory PDF, 459 pages, scanned from the Iseki master. No missing pages, no watermarks covering part numbers. You download a ZIP or PDF directly. The file is large because every illustration is high-res – you need to see the tiny KEY numbers on the hydraulic hose diagrams. Compared to Automotive Industry Overview sources, this is the gold standard because it comes from the equipment manufacturer, not a generic parts house. If you see a part code like 8595-211-001-20, you can trust it matches the case/upper housing on your TH4260 built after serial 230. No guessing.

Does this catalog cover the TH4260, TH4290, and TH4330 equally?

Yes. All three model numbers are listed in the same tables. The columns for each machine type (e.g., SSM48M for TH4260, SRM48F for TH4330) let you filter exactly which part fits your tractor.

What does the ‘ITC’ column mean?

Interchangeability code. 1 = new part replaces old (use new), 2 = old part replaces new (use old if available), 3 = not interchangeable. Always check ITC before ordering.

How do I find the serial number on my tractor?

Stamped on the engine block near the injector pump or on the transmission housing. The catalog uses serial number breaks in the lower column under QTY. Match your tractor’s serial to the range shown.

Can I use this catalog to identify parts for a non-European model?

The area code is E4 (Europe), but Iseki used the same part numbering system globally. Most part codes are identical. The differences are in area-specific options like PTO shields. Cross-check with your local dealer if unsure.
