Allis-chalmers 715 1975 Parts Catalog

You get a 715 backhoe-loader in the bay. The owner says the stabilizer cylinder leaks. You pull the parts catalog for the seal number. You flip open a third-party reprint and find the illustration doesn’t match the valve bank you’re staring at. That wasted hour is on your dime. This factory Allis-chalmers 715 1975 Parts Catalog kills that problem. 215 pages of original Allis-chalmers engineering, printed December 1975. No reprint, no photocopy, no aftermarket guesswork. Every part number comes from the same people who built the machine.

Backhoe Valve and Cylinder Diagrams

Page 12 kicks off the backhoe group. You get the control valve, swing valve, boom cylinder, dipperstick cylinder, stabilizer cylinder – all with item numbers tied to the text on the facing page. The backhoe valve & lines section (page 32? The TOC says Backhoe Valve & Lines is in the Backhoe Group starting page 12, but the actual page numbering puts the valve breakdown around page 14-16. I’ve used this catalog to pull a swing cylinder seal on a 715. The exploded view shows the cushion assembly and the exact O-ring stack. No hunting through generic hydraulic seal kits. [LINK_ID_EXT_0] provides context on agricultural equipment standards, but this manual gives you the factory part numbers.

Does This Catalog Cover the Engine Cylinder Head?

It covers the cylinder head assembly, including intake and exhaust valves, push rods, rocker shaft, tappets. The valve list specifies both exhaust and inlet valves with part numbers. If you need the valve stem seal or spring, you find it under Cylinder Head Cover & Rocker Arm. Page 6? Actually the engine section starts on page 2? No, the engine group is listed later in the catalog (pages 80-100 based on the bookmark structure). The alphabetical index on page 3 leads you straight to Valves. Don’t guess – use the index.

Use the Alphabetical Index to Find Parts Fast

The index on page 3 lists every major group: Air Intake, Backhoe, Cab, Cooling, Electrical, Engine, Attachments. Look up “Control Valve, Backhoe” – it directs you to the backhoe group. Look up “Valve” – you get engine valves and backhoe valves. The numerical index at the back cross-references every part number across all 215 pages. This is how you confirm you’re ordering the right bolt for the water pump pulley or the correct belt for the fan blade.

Air Intake and Exhaust: Manifold and Muffler Breakdown

Page 6 gives you the air cleaner assembly, intake and exhaust manifolds, and muffler group. Each component is itemized. If you need the gasket for the exhaust manifold, the part number is right there. Common hardware like bolts and lockwashers are listed indented – they’re not included unless specified. Read the footnote on page 4: “Common hardware listed indented beneath an item is NOT included unless specified.” Know that before you order.

215 Pages of Factory Part Numbers

Every page is a real scan of the original lithograph. The attachments section covers buckets – cutting edges and tooth groups for loader and backhoe. The cab section (page 165A) includes canopy parts. The electrical system section breaks down the alternator, starting motor, instrument panels, sending units, switches, wiring harnesses. Need the hour meter part? Page 44. Temperature sending unit? Page 44. The key switch? Page 44. All referenced from the index.

Understand the Electrical System Wiring

The instrument panel (gauges) on page 46 shows the fuse holder, fuel & voltage gauge, water & oil temperature gauge, warning lights, wire harness. The safety start switch is on page 44. If you’re troubleshooting a no-crank condition, the wiring diagram is in that section. [LINK_ID_EXT_1] covers general automotive electrical history, but this catalog gives you the actual wire colors and connector part numbers for the 715.

Source Validity: Why OEM Beats Aftermarket

I’ve had it with aftermarket parts catalogs that blur illustrations and misnumber items. This is the real document: Form 9004560, replacing 1012411, revised December 1975. Printed by Allis-chalmers. The page layout puts the illustration on the right and the text on the left – you read the item number from the picture, match it to the table, and write down the part number. No flipping back and forth between separate diagrams and lists. That’s how factory documentation should work. For related machines, see Allis-Chalmers HD-6EP Parts Catalog – Factory OEM 374 Pages or Allis-chalmers HD21A 1965 Parts Catalog – Factory OEM. Need a later model? Allis-chalmers HD16D, HD16DC 1970 Parts Catalog – OEM Factory Specs might help.

Does this catalog include torque specs for head bolts?

No. This is a parts catalog, not a service manual. It contains part numbers and illustrations – not torque values or repair procedures. You need the Allis-Chalmers 715 service manual for torque data.

What valve information is in this catalog?

Both engine valves (exhaust and inlet) and backhoe control valves are covered. Part numbers for each valve, seals, and associated hardware are listed under Cylinder Head and Backhoe Group.

How many pages is it?

215 pages.

Can I verify the part number before ordering from my dealer?

Yes. Use the numerical index in the back of the catalog. Enter your part number into the index, and it tells you every page where that number appears. Cross-reference with the illustration to confirm fitment. I’ve done this hundreds of times for old Allis-chalmers gear – it saves you from ordering the wrong stabilizer street pad or cutting edge.

Access the Factory Manual. You get a PDF that works on any device – searchable, printable, and identical to the paper catalog that Allis-chalmers sold through their dealers in 1975. No watermarks, no missing pages. Put it on your shop tablet next time a 715 rolls in. You’ll know exactly which backhoe valve seal to order, which alternator pulley fits, and which muffler group matches the serial number on the machine.
