Allis-chalmers 816, 816B 1974 Parts Catalog – Factory OEM Specs

Ever order a part for an Allis-chalmers 816 only to have it arrive and not line up? That’s what happens when you use aftermarket cross-reference charts or just eyeball it. This is the factory parts catalog for the 816 and 816B loader-backhoes, printed in 1974 by Allis-Chalmers. 461 pages of exploded views and part numbers. Not a reprint. Not a scan of a scan. This is the real deal.

The Allis-chalmers 816, 816B 1974 Parts Catalog – What You Get

You get a complete factory-published parts list organized by system. The catalog uses alpha grouping: air intake, hydraulics, drivetrain – everything in its place. Every part is identified with an item number. Common hardware like bolts and cotter pins is listed under the assembly they attach to. The foreword on page 3 tells you exactly how to read the entries, including how “assembly or packaged parts” are handled. If you need a part for the air cleaner, turn to page 43. That’s the Air Cleaner Group. The illustration shows you the exploded view, and the text below gives you the part number and quantity.

Page 2 – General Description Diagram

Page 2 shows a labeled drawing of the whole machine: 22 numbered components from the air cleaner intake to the swing frame. It also defines left and right hand from the operator’s seat facing forward. That orientation matters when you order a swing cylinder or stabilizer. This catalog enforces that convention throughout. Ignore it and you’ll get the wrong side.

How the Parts List Is Organized

Alphabetical by component name. Except for standard hardware, every part has an item number. The quantity listed is always the quantity needed for one assembly. If a bolt and lockwasher are part of a bigger assembly, they are noted – example: “Incl. Bolt, Lockwasher and Nut.” There’s a part number index at the back that tells you on which page each number appears. That means you can cross-check a loose part number you find on the machine. No guessing.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket parts catalogs often skip details – like the exact grade of bolt or the correct finish on a hydraulic fitting. This catalog came from the Allis-Chalmers Industrial Tractor Division in Topeka, Kansas. Every part number was verified by the engineers who built the machine. If you order using a part number from this catalog, you’re ordering what the factory intended. You can’t say that about a third-party list. The Automotive Industry Overview Automotive Industry Overview covers why factory specs matter in industrial equipment, but the short version is this: reprints introduce errors. This catalog doesn’t.

Audience Fit – Who Needs This Catalog

If you own an 816 or 816B loader-backhoe and need to rebuild the hydraulics, replace a bucket cylinder, or locate a stabilizer seal, this catalog is your starting point. Without it, you’re hunting through online forums or calling dealers with incomplete serial numbers. The catalog tells you to supply the tractor and engine serial numbers when ordering parts. That’s in the “How to Order Parts” section. It also says to state left or right hand from the operator seat. Beginners often mess that up. This catalog shows it clearly.

Frequently Asked Questions

Can I use this catalog to repair the engine?

No. This is a parts catalog, not a service manual. It tells you what to order, not how to install it.

Does this catalog cover the 816B only or both models?

Both the 816 and 816B are covered. The cover says “816 & 816B Loader-Backhoe.” Each model has separate part listings where they differ, so check your serial number.

Are part numbers still available from dealers?

Allis-Chalmers no longer exists, but many parts are still stocked by aftermarket suppliers. The original part numbers in this catalog are the key to finding replacements. You cross-reference them with current dealers or NOS sources. Without the factory number, you’re guessing. This catalog eliminates that guesswork. If a part is discontinued, you at least know what you’re looking for, and some dealers specialized in older equipment still use these numbers. Having the exact number lets you search for equivalents or used parts online, which is a lot better than trying to match by eye or by measurement that might be off.

What is the difference between the 816 and 816B models?

The catalog lists parts for both separately. Differences are mainly in the backhoe and loader hydraulics. The serial number range tells you which model you have.

You need this catalog on your workbench if you want to keep your 816 or 816B running without wasting money on the wrong parts. 461 pages of factory data, not a third-party guess. Access the Factory Manual from AutoRepairManuals and get the part numbers that actually match your machine.
