Iseki 4320, 4370 Parts Catalog

You need a part for your Iseki 4320 or 4370 tractor. You look up the number on a third-party site, get a vague description, and end up with a box of wrong parts. That wastes time and money. Here’s the fix: the factory Iseki 4320, 4370 Parts Catalog – 172 pages of real OEM data. This isn’t a generic compilation; it’s the same book the dealer uses to look up every 12-digit part number, every supersession, every quantity per tractor.

Engine Parts Breakdown – Cylinder Head and Block (Figs. 1-2)

The catalog divides the tractor into subsystems. Starting with the engine, Fig. 1 on page 47 shows the cylinder head assembly – head cover, valves, rocker arm components. Fig. 2 on page 49 covers the cylinder block and internal parts. Each part has a reference number that ties to the parts list with description, part number, and interchangeability notes. I’ve seen guys order a ‘water pump’ only to get the wrong one because they didn’t check the serial number break. This catalog stops that.

How to Use the Parts List Correctly – Page 2 Instructions

Page 2 explains the columns: Ref. No., Parts No., Description, Qty, Remarks. That 12-digit code? It’s the same one the dealer uses. Type that on your order sheet and you get the right part. The catalog also marks parts that are not sold individually and shows interchangeability – new type fits old, old does not fit new. Read this page before you order anything. Skip it and you’ll be calling the dealer twice.

172 Pages of Factory Part Numbers – What’s Inside

The catalog covers every subsystem: engine (Figs. 1-14), clutch, transmission, rear axle, PTO, hydraulic system, steering, front axle, brakes, electrical, and body. From the cylinder head on page 47 through the final figure, you get exploded views for every assembly. The index is straightforward – locate the figure number, find the reference number, and the parts list gives you the OEM number.

Audience: Who Actually Needs This Document?

Tractor owners restoring a TE 4320 or 4370. DIY mechanics working on their own farm equipment. Home garage enthusiasts who’ve been burned by aftermarket parts that don’t fit. This catalog eliminates the guesswork. A wrong hydraulic fitting can blow under pressure – don’t guess. Use the factory part number and save yourself a trip to the hospital.

Source Validity: OEM vs Aftermarket Alternatives

This is the official Iseki Parts Catalog from Tokyo, Japan. Not a reprint, not a third-party compilation. Aftermarket catalogs often combine multiple models or omit superseded parts. This one lists interchangeability with symbols – new type fits old, old not fits new (page 2).

For context on the Automotive Industry Overview, this catalog is a perfect example of why factory documentation matters. The Automotive Industry Overview background shows how parts numbering standards differ globally – but with OEM data you avoid the confusion.

FAQ – Iseki 4320, 4370 Parts Catalog

Does this catalog include part numbers for both TE4320 and TE4370?

Yes – both models are listed with separate columns for 2WD and 4WD variants.

How do I know if a part supersedes to a newer number?

The catalog uses symbols: new type fits old (arrow right), old does not fit new (arrow left). Page 2 explains them. Always check the Remarks column – if a part is marked with a dot, it’s a component of an assembly. Order the assembly unless you find the individual piece listed separately. The 12-digit code is the key – if you give that to the dealer, they can look up supersessions on their end.

Are the diagrams detailed enough for someone who hasn’t torn down an engine before?

They are explosion views with reference numbers. If you can match a number to a picture, you’ll find the right part. Beginners should read page 2 first – it explains how the catalog is organized.

What if the catalog says a part is ‘not sold as a single part’?

You buy the assembly. The catalog marks those with a specific symbol – see page 2. For example, a snap ring might be included in the yoke assembly.
