Case W14, 35A, 35WL, 850C 1982 Parts Catalog – OEM Factory Specs

You’ve got a 850C tractor with a 35A backhoe, and you’re staring at a pile of parts that don’t fit. Or you’re ordering from the dealer and they keep sending the wrong filter. That’s because you’re working off a universal parts list—or worse, a reprint that skipped the revision log. The Case W14, 35A, 35WL, 850C 1982 Parts Catalog is the only document that gives you the factory part numbers, correct descriptions, and the exact quantity needed per machine. Published in 1982, this 105-page catalog is the OEM reference for the W14 loader, 35A and 35WL backhoes, and the 850C tractor. If you want to stop wasting time and money on wrong parts, you need the original factory index.

General Information: How the Catalog Is Organized

This catalog isn’t a random pile of diagrams. It’s built with two indexes—Alphabetical and Numerical. The Alphabetical Index at the front (page 3 of the PDF) points you to major groups and assemblies. The Numerical Index at the back lets you look up a part number and find the exact page where it’s listed. Every part entry includes a reference number, the OEM part number, a description, and the required quantity. Look at the example on the OCR excerpt: a hydraulic oil filter assembly (ref. 1) breaks down into head assembly, element kit, housing, and individual components like NSS items. You don’t guess what’s in the box—you see the parts tree.

Abbreviations and Terms You Need to Know

If you see “NSS” next to a part, that means “Not Sold Separately.” Don’t bother asking the dealer for it as a standalone piece. “UAR” means “Use As Required”—shop supplies, gaskets, O-rings. “REF” marks a reference line in the drawing, not a part you order. And “RESERVED” means the slot is empty; don’t call the dealer asking for phantom items. This catalog also defines P.I.N. and serial number usage. Without these abbreviations, you’ll order the wrong piece and hold up the job. As a mechanic who has torqued more head bolts than most people have had hot meals, I can tell you—miss the NSS flag and you’ve wasted a week.

Right-Hand and Left-Hand: Critical for Ordering

Every part labeled LH or RH is referenced from the operator’s seat while facing forward. If you order a right-hand hydraulic line for the 35WL backhoe and it lands on the left, you just wasted $200. This catalog defines those terms on page 3. Look at the OCR: “The terms right-hand and left-hand … indicate the right and left sides of the machine as viewed from the operator’s seat.” That’s not optional—it’s the difference between a part that fits and one that fights.

U.S. and Metric Units: What’s in the Book

Fasteners and dimensions come in U.S. inches with metric equivalents. Bolts, nuts, washers—the hardware is listed by type. U.S. hardware gets inch sizes; metric hardware gets millimeter sizes. This catalog also shows quantities per machine. For example, the hydraulic oil filter assembly: one filter, one head, one element kit, one housing. If you need a replacement element kit, the part number D 43800 is right there on page 3. No guessing whether it’s SAE or metric—the catalog spells it out.

Ordering Parts: What You Must Specify

When you place an order from this catalog, you need the correct part number, full description, quantity, machine and engine model, machine and engine serial numbers, method of shipment, and shipping address. The catalog itself says so in the “Orders” section. Failure to include serial numbers means the dealer can’t check for supersessions or update your revision. This isn’t a suggestion—it’s how you get the right part in your hands.

Audience Fit: Who Needs This Catalog?

If you own a Case W14 loader, a 35A or 35WL backhoe, or an 850C tractor, and you’re tired of ordering parts by memory or relying on aftermarket listings that don’t match—this is for you. The 1982 Parts Catalog covers every nut, bolt, seal, and hydraulic component specific to those models. Beginners will appreciate the index system that lets you find parts without a parts counter. Home garage enthusiasts can finally order the right O-ring for the filter without cross-referencing five different websites. And if you’re a professional mechanic, you know the value of an OEM parts catalog when the customer is waiting.

Source Validity: OEM Reprint, Not Aftermarket

This is an official Case Parts Catalog, original 1982 printing. The front page clearly states “Reprinted” and “Printed in U.S.A.” Revision log pages are included so you can track updates. Aftermarket catalogs often skip the revision history or misprint part numbers. This one doesn’t. You’re getting the same document the Case dealer used in 1982. Compare that to a generic online list where the part number might be for a different model year. If you want factory accuracy, this is it.

Frequently Asked Questions

Does this catalog cover the engine and drivetrain parts?

Only those parts that are part of the backhoe or loader attachment assemblies. The catalog’s focus is the 35A/35WL backhoe and the W14/850C attachment systems. For engine overhaul or transmission internals, you need the corresponding service manual.

Is the part number D 43800 for the filter element kit still available?

That’s a question for your Case dealer. The catalog lists the OEM number as of 1982. Supersessions happen. You have the original number to start the search.

How do I know if my machine uses LH or RH for a specific hose?

Find the assembly drawing for your model. The part description will say “HOSE – LH” or “HOSE – RH.” Remember the operator’s seat reference. If you’re unsure, measure the old hose and match the part number from the numerical index.

Can I use this catalog for a 1985 850C?

It covers the 850C as of 1982. Later production runs may have introduced revisions. Check your machine’s serial number and compare to the range in the catalog. If your serial falls outside, you need a later revision supplement.

Don’t let a missing part number turn a two-hour job into two weeks. Access the Factory Manual and keep this 105-page OEM catalog on your bench.
