Cub Cadet 123 Parts Catalog

If you’ve spent an afternoon chasing a part number for your Cub Cadet 123 Parts Catalog and ended up with the wrong spring or bolt because an online finder had bad data, you know the frustration. That’s why I keep a stack of OEM catalogs on my bench. This is a direct scan of the factory document – 65 pages of exploded diagrams and part number tables. No generic cross-reference, no aftermarket guessing.

Cub Cadet 123 Parts Catalog – Battery Holder Breakdown

Page 1 starts with the battery holder. You see the bolt (IH-376294-R2), the wing nut (KH-X-276-7), and the hold-down clamp. Each part has a reference number and quantity. If you’re missing that 1/4-20 wing nut, you can order it directly. No need to guess thread pitch – it’s in the table. That’s the value of this catalog: factory data, not guesses.

Get the Right Brake Parts for Your 123

Brake system parts are on pages 3 and 4. The diagram shows the brake pedal assembly, return spring, brake rod, lever, and disc assembly. Part numbers like IH-394037-R1 (Safety Switch Release Lever Clip) are listed with availability codes: ‘S’ for service, ‘P’ for package, ‘/P’ for piece. Some parts show ~NLA – no longer available. That heads you off before you waste a phone call. Safety warning: using the wrong brake lining disc (IH-384719-R1) can cause failure. Stick to OEM numbers.

Carburetor Section: 31 Referenced Parts

Page 5 is the carburetor – 31 reference numbers in the diagram. From the throttle shaft to the float bowl gasket, everything is itemized. If you have a clogged main jet or a missing governor spring, the part number is right there. This catalog doesn’t tell you how to rebuild it, but it tells you exactly what to buy. Pair it with a factory service manual for the rebuild steps. Need spec on something like Automotive Industry Overview standards? That’s a separate document – this catalog stays focused on your Cub Cadet 123.

Why Use an OEM Parts Catalog Instead of Aftermarket?

Aftermarket part finders often group multiple model years together. This catalog is specific to the 123. The exploded view shows exactly how parts fit together. You see the order of assembly, which matters when you’re putting the brake linkage back together. A generic list might say “brake rod” – but is it the one with the coiled pin or without? Page 3 shows it. And if you ever work with refrigerant systems, know that for Refrigerant R1234yf you need a different manual – but for a Cub Cadet tractor, this catalog covers everything mechanical.

65 Pages of Factory Schematics

Sixty-five pages total. That covers the battery holder, brakes, carburetor, steering, front axle, engine, transmission, wheels, and electrical. Each section has a full-page diagram and a table with part numbers, descriptions, and quantity. The catalog was produced by Cub Cadet for dealerships – same document you’d see at a service counter. If you prefer digital over a greasy paper copy, access this PDF. It’s searchable, so you can find ‘Brake Lining Disc’ in seconds.

Is this a repair manual or a parts catalog?

It’s a parts catalog. It contains exploded view diagrams and part numbers, not step-by-step repair instructions.

Can I use this to find aftermarket replacements?

The catalog lists factory OEM part numbers. You can cross-reference those numbers with aftermarket suppliers, but the catalog itself only shows Cub Cadet’s original parts.

Does this manual cover every part of the Cub Cadet 123?

Yes, the 65 pages cover all major assemblies including the battery holder, brake system, carburetor, steering, engine, transmission, wheels, and electrical. Each section includes a diagram with reference numbers and a table listing part numbers, quantities, and descriptions. Some obsolete parts are marked ~NLA (No Longer Available). This is the same document used by dealerships to order parts.

How do I identify the correct part if there are multiple numbers?

Look at the illustration and match the ref number. Then find that number in the table. If a part has a dash (~NLA) it means discontinued. You may need to search for superseding part numbers.
