Airman AX30 Parts Catalog

If you’ve ever ordered a part for an Airman AX30 from an aftermarket supplier only to find the threads don’t match or the bracket holes are off by a quarter inch, you already know why this catalog exists. Third-party parts lists are transcribed by people who never touched a wrench. They skip the ICA codes, they ignore serial number breaks, and they sure as hell don’t tell you which revision supersedes the old one. That’s why you need the original Airman AX30 Parts Catalog – 392 pages of factory-sourced part numbers, interchangeability codes, and ordering instructions. Not a scan, not a reprint – a direct digital copy of the OEM document. One wrong part can cost you a day of downtime and a restocking fee. Avoid that with OEM data.

Interchangeability Codes I, P, T, and Y

On page 5 of this catalog you’ll find the ICA column – Interchangeability Code Array. Most aftermarket catalogs strip this out because it takes effort to copy. Here’s what each letter means: I means the replaceable part can be used instead of the original but not vice versa. P means you must not use the listed part; use the replaceable part instead. T means the replaceable part can be used as an assembly. Y means the two parts are fully interchangeable. If you ignore these codes, you might bolt on a part that looks identical but fails because the metallurgy changed. Use page 5 to cross-check every order.

What Information Does the Foreword Specify?

Page 3 of the catalog opens with a foreword that tells you the orientation convention: left, right, front, and rear are all from the operator’s seat facing forward, with the blade at the front. It also states that engine parts are not in this catalog – you need the separate ISUZU diesel engine 3KR2 parts catalog. If you’re troubleshooting an engine issue, you need that other book. This catalog covers everything else on the AX30 chassis and drivetrain.

392 Pages of Part Numbers and Illustrations

With 392 pages, this catalog covers the entire AX30 mini excavator – undercarriage, boom, arm, hydraulic system, controls, cab components. Each assembly has an illustration with reference numbers, and the numerical parts index at the back lets you look up any part number directly. That index alone is worth the price of admission when you have a worn seal with no readable number on the rubber.

Order Parts Correctly – Use the Serial Number

The ordering instructions on page 3 are written for people who don’t want to make two trips to the dealer. You need the model (AX30) – that’s stamped on the nameplate riveted to the front face of the main frame. The serial number is right below it, usually something like 867-000051. Write that down before you open the catalog. Next, find the assembly section you need – say, the final drive or the control valve. The parts list will show a column for serial number range; if your serial number falls within that range, the listed part number applies. If not, the replaceable part column tells you which part to use. Ignoring this step is how you end up with a hydraulic pump that has the wrong mounting flange. The catalog also lists the part name and quantity required. One more thing – the ICA column. Check that before you order. If the code is ‘P’, you must use the replaceable part, not the listed one. Page 5 explains all four codes. Do yourself a favor and read it.

How to Use This Parts Catalog: Item Numbers and Part Numbers

Page 4 explains the layout: each assembly illustration has item numbers that correspond to the parts list. Part numbers may consist of a letter and numbers or just numbers. The replaceable part column tells you if a newer part supersedes the original. Use the item number to locate the part in the list, then verify the part number against your machine’s serial number range.

If your shop works on multiple Airman models, you’ll want the companion manuals. Check out the Airman AX35-2 Parts Catalog – Factory Specs Mini Excavator for the larger chassis, or the Airman AX40-2 Parts Catalog – Factory OEM Parts Guide for the next size up. The Airman AX35-2 Excavator Parts Catalog is also available for the AX35-2 variant.

This catalog follows standard part numbering conventions used in the global automotive and construction industry, as outlined on Automotive Industry Overview. For a deeper understanding of interchangeability codes and supersession logic, the Automotive Industry Overview provides useful context. Knowing these basics helps when dealing with older machines where multiple revisions exist.

Does this catalog include engine parts?

No. Engine parts require the separate ISUZU 3KR2 parts catalog.

How do I find the correct part number for my AX30?

Start by locating your machine’s serial number on the nameplate attached to the front of the main frame. Then find the appropriate assembly illustration in the catalog, note the item number, and look up the part number in the corresponding parts list. Check the ICA column and the replaceable part column to see if there’s a superseded part number that fits your serial number range. Finally, verify the part number against the numerical index at the back of the catalog to ensure it’s the correct revision. If you skip any of these steps, you risk ordering the wrong part. The foreword on page 3 and the instructions on pages 4-5 explain every detail.

What does the ‘P’ code mean in the ICA column?

The ‘P’ code means the listed part must not be used. You must order the replaceable part number shown in the adjacent column instead.

Can I use this catalog to order parts for an AX35?

No. This catalog is specific to the AX30 model. Use the AX35-2 parts catalog for that machine.
