Allis-chalmers 260E 1967 Parts Catalog – What a Master Tech Expects From a Parts Book

If you’re working on an old Allis-Chalmers 260E tractor scraper and you’re trying to match a camshaft or a brake drum without the factory part numbers, you’re burning time and money. I’ve seen guys order three different bearings before they get the right one because they relied on a blurry aftermarket diagram. That’s why this 1967 Factory Parts Catalog exists. It’s 289 pages of exploded views, part numbers, and supersession info that Allis-Chalmers printed so you don’t have to guess. I’ve used these catalogs in my shop for decades – they flat-out work. The OCR excerpt shows the original notice about FIAT-ALLIS, but the catalog itself is pure Allis-Chalmers engineering from Milwaukee.

What’s Inside: 289 Pages of Factory Part Numbers

This is a parts catalog, not a service manual. That means you get every screw, gasket, seal, bearing, and subassembly listed with its original factory number. The table of contents runs from Accessory Drive (page 69) all the way to the Numerical Index. If you need the correct brake shoe, look up the Brake section starting on page 165 – the drum is listed separately under Drum, Brake. The cylinder is under Cylinder, Brake – but in this catalog they call it Rotochamber. Without the factory cross-reference, you’d never make that match.

Pages 14 through 28 cover the engine assembly, including the camshaft, cylinder block, connecting rod, and crankshaft. The camshaft bearing is listed on page 16, the main bearing on page 22. These are the exact part numbers your dealer or online supplier needs to pull the right parts. The transmission section begins on page 136 with the Case, Transmission, then splits into Clutch Packs on pages 140, 144, and 148. The torque converter is documented on pages 128 and 132. If you’re rebuilding the power shift, you’ll need those pages.

Engine and Drivetrain: Camshaft, Cylinder, and Transmission Breakdown

The Engine section (page 14 onward) lists the fan belt, compressor belt, water pump/generator belt, and all mounting brackets. The cylinder head gasket is on page 8 and page 24 – note that the head gasket is listed under both Gasket, Engine Head and again under Head, Cylinder. That duplication tells you the factory expected you to find it either way. The camshaft, engine entry on page 28 gives the part number for the cam and its bearings (page 16). The oil pan, oil filter (pages 51–58), fuel filter (58–66), and coolant filter (106, 109) are all fully detailed. If you need the brake linkage, it’s on page 6. That’s the kind of indexing you only get from an OEM parts catalog.

Brake and Hydraulic Systems: Factory Routing and Component IDs

Brake parts are scattered across several sections because this machine uses an air-over-hydraulic system. The Brake section (page 165) lists drum components, while Brake Camshaft is on page 162. The Brake Linkage is page 6, and the Brake Pedal is page 75. You also have the Rotochamber (listed as Cylinder, Brake) which is the air actuator. The hydraulic filter is on page 242, with its lines on page 250. The steering cylinder (page 254) and its lines (page 244) are also included. For the air compressor, see page 192, and the compressor governor on page 195. All lines – brake, hydraulic, fuel, compressor – are grouped under Lines (page 212) with individual subsections. Having one catalog that ties all these together saves hours of searching across multiple sources.

Source Validity: OEM vs Aftermarket Documentation

I flat-out distrust third-party parts catalogs for older equipment. They often repackage generic diagrams from unknown sources and mess up part numbers. This is a certified original factory print – Allis-Chalmers published it in 1967, form number 70194007, revised (5-67). The copyright page confirms it was lithoed in the U.S.A. and sold for $1.50. Every part number in here was verified by the factory engineers who designed the machine. When you order a bearing for the scraper pedestal (page 232) or a seal for the final drive (page 158), you match the factory strip-down sequence. That’s why I keep a stack of these on my toolbox. If you want to learn how real parts catalogs are structured, read the Automotive Industry Overview – but for actual part numbers, stick with the factory book.

Who Needs This Parts Catalog?

If you own a 260E tractor scraper and you’re doing any kind of overhaul – engine rebuild, transmission clutch pack replacement, brake reline, or hydraulic hose replacement – you need this. Even if you’re just troubleshooting a fuel nozzle issue, the Fuel Injection Nozzles and Holders supplement (form 657397) is mentioned but not included; the base catalog still gives you the engine fuel filter elements (pages 58–66). For the elevator scraper attachment, the catalog references Model 223 (form PC-42-1) separately. But everything bolted to the tractor itself is here. Shade-tree mechanics will appreciate the exploded views that show how the torque converter (page 128) comes apart. The numerical index at the back (page 275 onward) lets you look up a part number and find the page instantly. That’s a feature aftermarket catalogs rarely get right.

3 Reasons to Choose OEM Documentation

1. The part numbers are the ones the factory stamped into the steel. No cross-reference guesswork.
2. The illustrations show the exact assembly sequence – note how the clutch packs are split across three pages (140, 144, 148) because each pack is different.
3. Supersession notices and packaging references (see “Packaged Parts” on page 37) tell you if a bolt comes as a kit or single. That saves you from ordering ten individual bolts when a set exist.

Frequently Asked Questions

Does this catalog include torque specs or repair procedures?

No – this is a parts catalog only. You’ll need the corresponding Service Manual for the engine (form 643980) and the Torque Converter/Transmission manual (form 189100) for rebuild specs. The parts catalog gives you the component IDs and ordering numbers.

Can I use this to find a substitute for a discontinued part?

Yes, but only if the factory issued a supersession number – check the numerical index at the back (page 275). The catalog was printed in 1967, so parts that were discontinued later won’t show cross-references to newer replacements. For modern substitutes, you’ll need to compare dimensions from the diagrams.

What years does this cover for the 260E?

This parts catalog is for the 260E tractor as built through the 1967 model year. Later revisions (like the 1972 edition) may have different part numbers for the transmission clutch packs and brake drums. Check the serial number break on page 2 if you have later production.

Does it include the elevator scraper attachment parts?

Partially. The scraper itself (Model 223) is covered in a separate catalog (form PC-42-1). However, the tractor-mounted components – hitch assembly (pages 228, 230), scraper pedestal bearing (page 232), and elevator scraper hydraulic lines – are listed in this catalog.

If you want to stop chasing wrong part numbers and start ordering components that actually fit your Allis-chalmers 260E, this catalog is the tool you need. Access the Factory Manual from AutoRepairManuals and keep a copy on your tablet or printed out next to the tractor. Every page is original OEM – no aftermarket copy, no blurred scans. I’ve used factory catalogs like this for 28 years; they’re the difference between a three-hour job and a three-day headache.
