Case 450, 450B, 35, 850, 850B 1980 Parts Catalog

When you need to order a replacement part for a Case 35 backhoe mounted on a 450 or 850 series, this is the document that keeps you from buying three wrong parts before you get the right one. The Case 450, 450B, 35, 850, 850B 1980 Parts Catalog is a factory-produced 126-page reference that shows every nut, bolt, seal, and assembly with the original part numbers. No guesswork.

Understanding the Case 450, 450B, 35, 850, 850B 1980 Parts Catalog

The catalog starts with an Alphabetical Index at the front and a Numerical Index at the back. Page 2 shows the revision record log – keep that updated so you do not order parts from a superseded page. The log is a table you must fill in each time you receive an updated page. Case would send revised pages when parts were superseded. If you do not insert those pages, your catalog becomes obsolete. Failure to keep your catalog up to date will result in confusion and may cause you to order wrong parts – that is a direct quote from page 2. Page 3 explains abbreviations like HHCS (hex head capscrew), NSS (not sold separately), and UAR (use as required). If you skip reading those, you will order the wrong fastener type. The catalog uses U.S. units with metric equivalents for dimensions, but hardware sizes are listed according to type – inches for U.S. hardware, millimeters for metric. Pay attention to that detail.

How the Parts List is Organized

Each page has a table with columns: REF (reference number in the drawing), PART NO., DESCRIPTION, and REQ’D (quantity). Indented items are sub-components of the assembly above them. The example on page 3 shows a track roller assembly with six rollers, each requiring two nuts, two washers, two block and retainers, two O-rings, and two face seal assemblies. The face seal assemblies are further broken down into individual parts. This level of detail lets you order only the seal instead of the whole assembly. If you need only the O-ring, you order it separately – the catalog shows you the exact part number and quantity. Machinery items (Mach. Item) must be ordered from the Machinery Price List – note that.

Right-Hand and Left-Hand Orientation

Terms like R.H. and L.H. are defined from the operator’s seat facing forward. This is critical when ordering side-specific parts like boom cylinders or stabilizer pads. Get the side wrong and the part will not fit. The catalog states this clearly on the general information page.

Ordering Parts: What You Must Provide

The catalog specifies that orders must include correct part number, full description, quantity, machine and engine model, machine and engine serial numbers, method of shipment, and shipping address. If you omit the serial numbers, the dealer may send a part that is not compatible with your machine’s build. Write those numbers down before you call.

Why Use Factory OEM Parts Catalog Over Aftermarket Sources?

Aftermarket parts catalogs often copy the drawings but miss critical notes about supersessions or revisions. This manual is a direct reprint of the original Case publication B1359, issued June 1980. It replaces earlier catalog A1359 – if you have that one, discard it. The factory updates pages when parts change. You need the original to avoid ordering a part that no longer fits. The automotive industry relies on accurate documentation; for a broader context, see Automotive Industry Overview. Case was a major player in construction equipment; Automotive Industry Overview can give background on the industry.

This 126-page catalog covers the 35 backhoe for 450, 450B, 850, 850B, and W14 models. It does not cover the carrier machine’s engine or drivetrain – only the backhoe attachment itself.

Frequently Asked Questions

Does this catalog include engine parts for the carrier machine?

No. This catalog covers only the 35 backhoe attachment, not the engine or drivetrain of the 450, 850, or W14 carriers.

How do I locate a part number if I only have a description?

Turn to the Alphabetical Index at the front. Look up the major assembly name – for example, ‘Boom’ or ‘Bucket Cylinder’. The index gives the page number where that assembly is illustrated. On that page, find the component in the exploded view and read the corresponding part number from the table. If you have a part number and need to find which page it appears on, use the Numerical Index at the back – it lists every part number in numerical order with the page reference. That means you can always cross-reference between the two indexes. Keep a pencil handy to mark the pages you use most.
