Case 480B, 26, 26B, 480 1975 Parts Catalog

If you are chasing a part number for a Case 480B, 26, 26B, 480 1975 Parts Catalog because the aftermarket cross-reference led you to the wrong seal again, you know the frustration. This is the factory catalog – the one Case issued in 1975, reprinted from their original plates. 162 pages of exploded views, part numbers, and revision notes that tell you exactly what changed from the previous issue D1124. No guesswork about which nut goes where. I have lost count of the hours I wasted as a young tech trying to match a part by eyeball. This catalog stops that nonsense cold.

Let me walk you through what you get, and why you need it on the bench next to your torque wrench.

Parts Catalog Structure: Indexes and Orders

The Catalog is arranged with two indexes. The Alphabetical Index upfront lists major groups and assemblies. The Numerical Index in the back gives every part number and the page where it appears. Orders must specify the correct part number, full description, quantity, machine model and engine model, plus serial numbers. Page 3 of the catalog spells out the exact format. If you send in a vague request, you get the wrong part. Period.

Changes and Updates: Why This 1975 Edition Matters

Case updated this catalog from D1124 to E1124. The note on page 3 says: “This catalog replaces the previous issue – D1124 – which is obsolete and should be discarded.” Revised pages will be issued as the machine changes. If you do not insert those revised pages, you will order wrong parts. That is not a maybe. I have seen guys order a whole hydraulic pump because they used an outdated page. This catalog keeps you current.

Understanding Exploded Views and Part Numbers

All parts are shown in exploded views with circled reference numbers. Those numbers correspond to the REF column in the parts list. Example from the catalog shows a track roller assembly with six rollers per machine, each roller using two nuts, two washers, two block and retainers, two O-rings, and two face seal assemblies. The face seal assembly is further broken down into body, rubber seal, and plastic retainer. You get the part numbers for every piece. That means you can order a $2 seal instead of a $200 assembly because you see the breakdown.

Description, Quantity, and Machinery Items Explained

Indented items in the parts list are subcomponents of the item above them. The REQ’D column tells you quantity per machine. Machinery items (marked “Mach. Item”) must be ordered from the Machinery Price List – not from the parts catalog. Page 4 of the catalog shows a clear example with a mounting frame. Ignore that column and your order gets kicked back. This is the kind of detail aftermarket reprints strip out. The original 1975 Case press run includes it.

Right-Hand vs Left-Hand Orientation for Loader and Backhoe

Determining right-hand and left-hand sides of the 26 or 26B loader mounted on a 480 or 480B tractor is done by standing at the rear of the unit, facing forward. If a backhoe is attached, sit in the operator seat and face the backhoe. The catalog gives you the convention so every part ordered as R.H. or L.H. lands correctly. I have seen a guy order two left-hand hoses because he guessed the side. This catalog kills that mistake.

If you also need the operator-side procedures for your Case equipment, look at the Case 480B 1995 Operator’s Manual for daily operation checks, or the Case 26 Backhoe Operators Manual for backhoe-specific controls. For a full machine overview including both loader and backhoe, the Case Model 26 Loader and Backhoe Operators Manual gives you the operational side. The parts catalog here is the identification tool – you pair it with an operator or service manual to complete the job.

For context on why factory documentation matters across the Automotive Industry Overview, the standardization of parts numbering and revision control is not optional. Automotive Industry Overview shows how manufacturers like Case forced suppliers to adhere to strict part identification – this catalog is the living record of that system.

FAQ

Does this catalog include repair procedures or torque specs?

No. This is a parts catalog – it lists part numbers, quantities, and exploded views. Torque specs and step-by-step repair steps are in the separate service manual.

How do I find the page for a specific part number?

Use the Numerical Index at the back of the catalog. Every part number listed in the index directs you to the page where that part appears in an exploded view. For example, on page 4 of the catalog you will see the index reference for the track roller assembly. Write the part number down, flip to the Numerical Index, and you are on the correct page in under a minute. If the part number is not in the index, either the part is a machinery item (ordered separately) or the catalog has not been updated. Check the revision date of your copy – the 1975 issue E1124 supersedes D1124, so make sure you have the latest.

You need the right part the first time. The factory Case parts catalog for the 480B, 26, 26B, and 480 models puts every nut, seal, and frame in your hand on paper. Stop wasting time with generic cross-references. Access the Factory Manual and keep it on your bench.
