Iseki TE4320, TE4370 Parts Catalog

You pull the head on an Iseki TE4320, TE4370 tractor and find a cracked rocker arm. The local supplier asks for the part number, and you hesitate because the old rocker is stamped with a number that doesn’t match anything in aftermarket catalogs. That hesitation costs you an hour of cross-referencing – and still you order the wrong piece. This is where a genuine Parts Catalog pays for itself in the first ten minutes. No guessing, no calling back.

Engine Section: 17 Figures Covering Cylinder Head to Injection Pump

This catalog breaks the engine down into 17 separate figure groups. Fig. 1 gives you the cylinder head assembly and head cover parts with every bolt and gasket called out by its 12-digit code number. Fig. 2 handles the cylinder block – you’ll find the block itself, liners, and all the plugs. Fig. 8 covers the valve mechanism: camshaft, idle gear, rocker arm assembly. If you’re rebuilding the top end, those figures are worth the price alone. Need the injection pump parts? Fig. 15 and Fig. 17. Fuel system nozzles and pipes are in Fig. 13. Each figure has a corresponding parts list with part numbers, quantities per tractor, and interchangeability notes.

Does This Catalog Cover the Valve Mechanism?

Yes, and it’s laid out so you can find the exact valve spring, retainer, or rocker shaft. Fig. 8 includes the camshaft idle gear and rocker arm assembly with separate part numbers for each component. The catalog uses a reference number system: each item in the drawing gets a Ref. No. that matches the parts list. No squinting at blurry microfiche copies – these are factory line drawings, clean and dimensioned. You’ll see the valve clearance adjustment shims listed too, if your model uses them.

262 Pages of OEM Part Numbers

262 pages total, and every page is a direct scan of the original Iseki document printed in Tokyo, Japan. The PDF is searchable if your device supports it, but even flipping through the figures is faster than scrolling through an aftermarket database. Part codes are 12 digits – the catalog explains the structure, including which codes start with “V” for market-available parts. You also get the symbol legend at the front: ★ for made-to-order, A for not sold as a single part, B/C/D/E for interchangeability. That symbol table alone prevents ordering a part that won’t fit the updated serial number range.

Use the Reference Number System Correctly

Every figure has a column marked “Ref. No.” – that’s the number on the drawing. You cross it to the part number and description. Sounds obvious, but I’ve watched guys skip this step and grab the wrong item because they looked at the picture instead of the line. The catalog also lists quantities for 2WD and 4WD versions of both the TE4320 and TE4370 separately – four columns: A (TE4320 2WD), B (TE4320 4WD), C (TE4370 2WD), D (TE4370 4WD). If you’re working on a 4WD TE4370, you look at column D. If the quantity says “AR” (as required), order what you need, not a fixed number.

Parts Interchangeability Symbols: What They Mean

One of the most skipped pages in any parts catalog is the symbol explanation. Page 2 of this catalog spells it out: ★ means made to order (expect delay), A means the part is only sold as part of an assembly, B means the new part can replace the old one but not vice versa, C means the old part cannot be used on the new model, D means abolished, E means newly included. If you see a B symbol next to a cylinder head gasket, you can use the new part number on an older engine serial number. That kind of detail keeps you from ordering obsolete stock or returning parts.

Who Needs This Parts Catalog?

If you own or work on an Iseki TE4320 or TE4370 tractor – 2WD or 4WD – this is the only parts book you need. It’s aimed at mechanics, fleet maintenance shops, and serious DIYers who rebuild their own equipment. The catalog assumes you know how to disassemble and reassemble the tractor; it does not include repair procedures or torque specs. For repair instructions, pair this with the corresponding service manual. But for ordering the right piston ring, the correct oil pump gasket, or the exact starter drive, this catalog is the source of truth.

Source Validity: OEM vs Aftermarket

This document is a direct scan of the original Iseki Europe S.A. publication – N.V. Iseki Europe S.A., Sterrebeekstraat 179 D4, B-1930 Zaventem – Belgium. That’s the same booklet dealers used. It’s not a third-party compilation, not a wiki, not a photocopy of a photocopy. I’ve seen aftermarket parts catalogs that group parts by generic categories and miss the fine-print interchangeability notes. A factory Iseki catalog like this one includes the exact 12-digit code for every fastener, seal, and bracket. When you call the dealer with that code, you get the right box, no returns.

If you want background on why factory documentation matters in the Automotive Industry Overview, you can read more. But for this tractor, you already have the right document.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities but does not give assembly torque values. You need the factory service manual for those numbers.

Can I use this catalog to order parts for an TE4320 with a different serial number range?

Yes, but check the interchangeability symbols (page 2). If the part shows a B symbol, the new part fits the old tractor. If it shows a C symbol, it will not. The catalog covers all serial numbers for the TE4320 and TE4370 sold in Europe.

How are the figures organized?

Each figure is a line drawing showing exploded assembly views. Figures are grouped by system: Engine (Figs 1-21), then drivetrain, hydraulic, electrical, etc. The table of contents lists every figure by name and page number.

What if I need a part that is listed as “★ made to order”?

Those parts are not stocked – you order them from Iseki and expect a longer lead time. The catalog still gives you the correct part number so you don’t order the wrong one. Plan ahead 2-3 weeks.

Stop wasting time with aftermarket part guesses and returned boxes. Access the Factory Manual and get the exact 12-digit codes for every component on your Iseki TE4320 or TE4370.
