Cub Cadet 70, 100 Parts Catalog

If you’re wrenching on a Cub Cadet 70, 100 Parts Catalog is the only thing that belongs on your workbench. I’ve rebuilt more small engines than I can count, and I’ll tell you straight: guessing part numbers is how you end up with a box of wrong bolts and a tractor that sits. This is an original factory parts catalog, 86 pages of exploded views and OEM part numbers for the Cub Cadet 70 and 100. No aftermarket interpretations. No reprints. Just the factory specs.

Battery Holder and Brake Parts Breakdown

The catalog opens with the battery holder assembly. Page 1 shows the bolt, battery hold down (part number IH-376294-R2) and the clamp. You get the exact International Harvester reference numbers. The brakes section on page 4 lists the disc, brake lining (IH-384719-R1) and the pedal assembly. Every part has a reference number, a quantity, and a serviceability code (S/P/F). That’s what you need when you’re ordering from a dealer and they ask for the suffix.

86 Pages of Factory Part Numbers

This isn’t a service manual. You won’t find torque specs or step-by-step repair procedures here. It’s a parts catalog. But if you’re rebuilding a Cub Cadet 70 or 100, you need the correct part numbers to match what came from the factory. The catalog covers the engine, transmission, steering, electrical, and body. Every page is an exploded diagram with a table listing the part number, description, and whether it’s still available or replaced. That saves you the phone call to a parts guy who doesn’t know a 70 from a 100.

Does This Catalog Cover the Carburetor?

Yes. The OCR excerpt shows a Carburetor I section starting on page 5. It includes the location of the carburetor number and a detailed diagram with 28 reference points. You’ll see everything from the fuel inlet to the throttle shaft. If you need a specific gasket or float, the part number is right there. No cross-referencing a generic aftermarket list. You get the OEM number from Cub Cadet. That’s how you make sure the choke linkage fits.

Use the Reference Numbers Correctly

Each diagram has a reference number (like 1, 2, 3) linked to the table. Don’t skip that. I’ve seen guys order “the brake lining” and get the wrong one because they didn’t check the reference number. The catalog tells you: disc, brake lining, ref #1 is IH-384719-R1. The retainer is IH-384720-R2. Mix them up and you’ll be filing metal to make it fit. That costs you time. Do it right the first time with the factory data.

Carburetor I: Exploded View and Part List

Page 5 covers the first carburetor assembly. The drawing shows the location of the carburetor number — critical if you’re ordering a replacement. The part list includes bolts, gaskets, and linkages. For example, the throttle shaft is identified by reference number. If you’re rebuilding a Walbro or Kohler carb on a 100, this is the map. Without it, you’re guessing which jet goes where. I don’t guess. Neither should you.

Can I use this catalog to find torque specs or rebuild procedures?

No. This is a parts catalog only. It lists part numbers and exploded views. You need a separate service manual for torque values and step-by-step procedures.

How do I identify which part number fits my specific 70 or 100 serial number?

The catalog groups parts by model and assembly. Start with the exploded diagram for your section (e.g., brakes). Match the reference numbers on the diagram to the table. The part number column gives the OEM number. If the part is superseded, the catalog notes a replacement number. Always check the suffix letters (R1, R2, etc.) — they indicate design changes. If you have an early 70, the battery hold-down clamp might be different from a late 100. The catalog lists both variations under the same assembly, so cross-reference your serial number range if possible. For the best accuracy, compare the physical part to the diagram. The brake disc (IH-384719-R1) is a 2-piece lining disc; if your tractor has a single-piece disc, you likely have a different revision. Use the reference numbers to avoid ordering the wrong one.

This catalog gets you the right part numbers. You still have to turn wrenches. But with the factory data in hand, you won’t waste time sorting through wrong parts. Get the original OEM breakdown. Access the Factory Manual from our site and stop guessing.
