Allis-chalmers 940 1976 Parts Catalog – Factory OEM Specs

You have a torn hydraulic line, a worn bucket tooth, or maybe a cracked cylinder head on your 940 loader. You crack open some aftermarket parts list and the part numbers don’t match what you pulled off. That costs you time, money, and a trip back to the parts counter. This Allis-chalmers 940 1976 Parts Catalog is the only document the factory ever issued for ordering the right parts. 235 pages, printed December 1976, straight from the Milwaukee engineering division. If you’re working on one of these machines, this is the map.

Parts Breakdown and Engineering Drawings

Every illustration in this catalog sits on the left-hand page with the text on the right. Each part gets an item number that lines up with the part number, quantity, and description in the columns. Common hardware like bolts, nuts, and cotter pins is listed indented under the assembly they belong to – but unless the description says “Incl. BOLT, LOCKWASHER & NUT,” don’t assume it’s included. That level of detail is exactly what you need when rebuilding the loader frame or the Automotive Industry Overview practices don’t apply to agricultural equipment sourcing.

What Systems Does This 235-Page Parts Catalog Cover?

Open to the alphabetical index on page 3. From AIR INTAKE & EXHAUST through TOOL MODULE GROUP, LOADER, the coverage is complete. You get the engine group with cylinder block, cylinder head, valves, rocker arm group, turbocharger. Fuel systems section includes injection pump components, nozzle holder assemblies, hand primer pump. Hydraulics covers control valves, power steering, ram cylinders, flow dividers. Power train group has the differential, brake parts, transmission clutch groups, drive shafts. Attachments list bucket assemblies, canopy group, heater, wiper motor. This is not a service manual – it’s a parts identification catalog.

235 Pages of Factory-Issued Part Numbers

Every part number printed here came from Allis-Chalmers Agricultural Equipment Division in 1976. No third-party renumbering. No guessing whether a bolt is Grade 5 or Grade 8. The numerical index at the back of the catalog cross-references every part number to the page where it appears, so you can verify you’re ordering the correct component the first time. Page 3 through page 235 – all factory data.

Use the Numerical Index to Verify Part Numbers

When you pull a part off the machine, write down the number stamped into it. Flip to the back of this catalog and find that number in the numerical index. It tells you exactly which page and illustration shows that part in context. Then you can confirm the supersession or alternate part before you call your dealer. That method saves you from buying the wrong water pump, the wrong cylinder ram seal, or the wrong gear for the transmission. Aftermarket catalogs often skip this cross-reference step – this factory manual does not.

Engine and Cylinder Head: Detailed Exploded Views

The engine section starts with the cylinder block and works through crankshaft bearings, camshaft gear, piston and connecting rod assemblies, and the cylinder head with valve covers. Exhaust and intake valves are listed separately. The rocker arm group includes the camshaft, lifters, and rocker arms. If you’re rebuilding the top end of the 940’s diesel, you need this catalog to order the valve stem seals, head gasket, and the correct length pushrods. The water pump, fan, and radiator group in the cooling systems section uses the same exploded-view format – item numbers line up with part numbers.

Hydraulic and Powertrain Groups: Factory Identification

Hydraulic system parts include the control valve, auxiliary pump and motor assembly, ram cylinders, flow divider, and the entire reservoir group with filter element and relief valve assembly. The power train group covers the axle assemblies, differential, brake master cylinder, power cylinder, and the complete transmission with converter, forward and 3rd clutch, low speed clutch, reverse and 2nd clutch. Each clutch group has its own set of gears, seals, and pistons. Without this catalog, matching those internal parts to the right part number is guesswork.

Why Factory OEM Documentation Beats Aftermarket Copies

Aftermarket parts catalogs often re-index part numbers or omit the numerical index entirely. They sometimes crop illustrations, making it impossible to see how a bracket aligns with the cylinder head. This Allis-Chalmers catalog is a direct scan of the original Form 9005001 booklet. The page numbering matches the factory version. The bolt quantities and descriptions are exactly as the engineers wrote them. If you want to keep your 940 loader running with genuine parts, you work from OEM specs.

Does this catalog include repair or service procedures?

No. This is a parts catalog only. It does not contain torque specs, overhaul steps, or adjustment procedures. You need the service manual for that.

How do I find a part number for a specific component like the cylinder ram seal?

Use the alphabetical index at the front of the catalog to locate the section (e.g., HYDRAULICS – Cylinder, ram assy.). Turn to the page listed. The left-hand page shows an exploded illustration with item numbers. The right-hand page lists each item number with its part number, quantity, and description. Write down the part number, then verify it in the numerical index at the back of the catalog to make sure it hasn’t been superseded or listed on another page. That two-step process eliminates ordering the wrong seal.

Whether you are rebuilding the entire loader or just replacing a bucket tooth, start with the right information. This 1976 factory catalog gives you the part numbers, illustrations, and indexes you need to order correctly. Automotive Industry Overview may cover mass production, but it won’t tell you the difference between a Dump Cylinder and a Lift Cylinder for the 940. This catalog will. Access the Factory Manual now.
