Case 430, 23 Parts Catalog

If you’re wrenching on a Case 430 Construction King with a Model 23 loader or backhoe, you need the part numbers from the factory, not some aftermarket guess. This 130-page Case 430, 23 Parts Catalog is the genuine reprinted OEM book – same one the Case dealer parts counter uses. Every exploded view, every reference number, every part description came straight from the engineering drawings. I’ve seen too many guys order a seal kit by dimension instead of by part number and end up with the wrong stack height. That’s wasted time on a 30-year-old machine. This catalog fixes that.

Exploded Views: How the Catalog Organizes Assemblies

The illustrations in this Parts Catalog show each assembly pulled apart – steering cylinder sockets, backhoe bucket linkages, loader frame mounts. Figure 1 and Figure 2 in the manual map serial number locations for the loader and backhoe, both tagged as Model 23. Reference numbers line up with a parts table that gives you the CASE part number, description, and quantity required. No guessing if a bolt is 1/2-20 NF x 2-1/4” – it’s right there on page 4. Page 1 lists the compatibilities: Model 23 Loader and Backhoe for the Model 430 Construction King Wheel Tractor.

Serial Number Locations: Why They Matter

Before you order a single part, you need to verify your machine’s serial number. The manual includes two figures – one for the loader, one for the backhoe – showing exactly where the serial number is stamped. On the loader it’s B61364, on the backhoe B60664. Write that down before you call a dealer. Also check the hydraulic fluid specs; the manual lists the factory-recommended fluid type. Use the wrong viscosity in a San Antonio summer and your pump will tell you about it.

Indented Descriptions: Reading the Part Numbers Correctly

Pay attention to the indented parts in the description list. Those indented lines are sub-assemblies – parts that belong to the assembly listed above them. The quantity in the “Number Required” column for indented items is the count per sub-assembly, not per machine. For example, the rear steering cylinder (ref. A 55159) has a socket assy (A 56208) with its own adjusting plug and ball seats. If you skip the indent and order one plug when you needed two seats, you’ll be waiting on another shipment. That’s the difference between a parts catalog and a guessing game.

Right Hand vs Left Hand: Orientation on the Machine

The manual defines right and left as if you’re sitting in the operator’s seat facing forward. That’s standard for heavy equipment, but it’s worth checking because a lot of guys confuse it with standing in front of the machine. If you’re ordering a loader latch pin or a backhoe lever, that orientation decides whether you get the correct part. The catalog doesn’t assume you know – it spells it out in the “Terms” section.

130 Pages of Genuine OEM Part Data

130 pages. Every page is a scanned reprint from the original CASE publication, not a third-party transcription. Aftermarket catalogs drop hardware descriptions or change the reference numbers – this one keeps everything: cotter pins, HHCS bolts, O-rings, hydraulic cylinder sockets. The alphabetical index in the front gets you to the major group; the numerical index in the back cross-references part numbers to page locations. Compare that to a PDF you find on a forum. I’ll take a factory catalog every time.

FAQ

Is this a repair manual with step-by-step instructions?

No – this is a Parts Catalog. It lists part numbers and exploded views, not service procedures.

How do I find a specific part for my Model 23 backhoe?

Start with the alphabetical index in the front to locate the assembly group (e.g., Backhoe Swing Cylinder). Then go to the page listed – each page has an exploded diagram with reference numbers. Match the reference number to the parts table for the CASE part number, description, and quantity. If you have the old part, cross-reference the number in the numerical index at the back. The manual also shows serial number locations so you can verify your machine’s variant before ordering.
