Aichi RV-060, IRV-200, 55 Parts Catalog – 62 Pages of OEM Factory Parts Data

If you’ve ever ordered a part for an Aichi RV-060 or IRV-200 and ended up with the wrong assembly because you guessed the number, you know the frustration. This Aichi RV-060, IRV-200, 55 Parts Catalog is the original OEM document that tells you exactly which part goes where and how it fits into the bigger assembly. No aftermarket cross-reference that might be off by one digit. It’s 62 pages of factory-sourced data, printed by Aichi Corporation themselves.

62 Pages of OEM Parts Data for Aichi RV-060, IRV-200, 55

Every page in this catalog is laid out with a parts illustration, a part number, a quantity, and a level column. The level column is critical. It tells you whether a part is a standalone item (level 1), a component inside an assembly (level 2), or a sub-component of that component (level 3). If you skip checking the level, you might order a whole assembly when you only needed a seal. That’s a waste of money and time. The catalog covers the RV-060, IRV-200, and model 55. Serial number ranges are listed for each part, so you can verify fitment before ordering.

How the Level Column Saves You from Ordering the Wrong Assembly

Look at the foreword on page 3 and 4 of the PDF. It explains the LEVEL system in plain English and Japanese. Assembly parts get a “1” in the level column. Components that belong to that assembly get a “2”. If those components are themselves assemblies, their parts get a “3”. This is not complicated—once you understand it. But if you ignore it, you’ll be the guy who ordered a complete hydraulic valve body when you only needed a spool. The catalog tells you which level you’re looking at. Use it.

Understanding the Remarks Column: Assembly vs. Loose Parts

The Remarks column uses symbols like *, □, and K. These are not decorative. A * means the part is only supplied as part of an assembly—you cannot order it loose. The assembly part number is listed right after the symbol. A □ indicates the part is supplied semi-finished; you may need to machine it yourself. K marks service kit components. If you miss these symbols, you’ll order a part that doesn’t exist as a standalone. The catalog gives you that information on every line. Aichi SR18AJ SR21AJ SR18A SR21A Parts Catalog – 300pp OEM is another factory document with similar symbols.

Read the Foreword Before You Order

Page 1 of the PDF includes the foreword in both Japanese and English. It tells you that drawing numbers and page numbers are not necessarily consecutive. It also warns that parts may change due to product improvements without notice. When you place an order, you must state the model, serial number, specification, and manufacturing date. The catalog is only useful if you supply those details. Skip the foreword and you risk ordering a part that was superseded two years ago. Aichi SR12B SR12BJ ISR40B ISR40BJ Parts Catalog – OEM Factory List and Aichi SR12B, SR12BJ, ISR40B, ISR40BJ Parts Catalog – Factory OEM follow the same format.

Why OEM Parts Catalogs Beat Aftermarket Cross-References

An aftermarket site might show a part number and say “fits Aichi RV-060.” But they don’t tell you whether that part is level 1 or level 2, or if it’s supplied as an assembly only. This catalog is the original factory document. The part numbers are verified by Aichi Corporation. The illustrations are taken directly from the engineering drawings. If you need to understand the Automotive Industry Overview of parts documentation, this is the gold standard. Automotive Industry Overview covers why OEM spec matters. When you use a factory parts catalog, you eliminate guesswork. That’s the only way I work.

Does this catalog include torque specs?

No. This is a parts list, not a service manual. It gives part numbers, quantities, and assembly structure, not torque values or repair procedures.

How do I know which revision of the catalog applies to my machine?

The foreword explains that drawing numbers and pages are not consecutive. You must verify your serial number against the serial number ranges listed in the catalog. The catalog includes a serial number column for each part. If you have a machine built after the catalog’s publication, some parts may have been superseded. Contact Aichi for the latest revision. The catalog is dated but still useful for older models, especially for the RV-060, IRV-200, and 55. Cross-reference your machine’s serial number with the “Serial No. of machines” column in the catalog. If you’re unsure, call Aichi’s parts department with the serial number from the machine’s nameplate.

If you need to order parts for an Aichi RV-060, IRV-200, or 55, get the factory document. Sixty-two pages of OEM data that keeps you from ordering the wrong piece. Access the factory manual and keep it on your bench.
