Cub Cadet 1105 Parts Catalog – 66 Pages of Factory OEM Parts Breakdown

Cub Cadet 1105 Parts Catalog is the only parts list you should trust when ordering anything for this machine. I have seen too many guys slap on a generic aftermarket gasket or bolt because they guessed the part number, then spent a Saturday chasing a vacuum leak or a stripped thread. A factory parts catalog kills that guesswork. This one runs 66 pages, covers every assembly from the air cleaner to the brake pedal, and uses OEM part numbers straight from the manufacturer. If you are turning wrenches on a 1105, this is the document you need on the bench — not a scanned photo from some forum.

Parts catalogs are not service manuals. They do not give you torque sequences or timing specs. But they save you more time than a service manual because you stop ordering the wrong parts. Page 1-2 alone shows the air cleaner assembly with 12 individual parts — each with a factory number, description, and quantity. You can call your dealer with that list and get the exact screw, gasket, or cartridge without returning anything. That is the kind of precision that keeps a job moving. Aftermarket lists often merge parts or skip hardware that is listed separately. Not this catalog.

Air Cleaner Assembly: Page 1-2 Parts Breakdown

First section in the book is the air cleaner. Twelve line items, every screw and gasket accounted for. The cover (ref #3) includes gasket #5 as part of the assembly — a detail aftermarket diagrams miss. The cartridge (#8) is listed as BS-393725. If you order that number, you get the right filter element. The body (#11) is BS-397321. Small differences in part numbers matter. A BS-397971 gasket will not fit on a BS-397321 body, even if they look similar. This catalog shows you exactly what goes where and the original engineering part number. That eliminates returns and wasted labor.

Battery & Mounting: Factory Hardware Specs

Battery replacement sounds simple until you realize the hold-down rod length, the wing nut thread size, and the lock washer stack. Page 3-4 lists the battery tray (703-1144), the two rods (LH 711-3142, RH 711-0222), and the specific washer sizes: .281 x .500 x .056 for the rod bolts (ref #6). That .281 inner diameter is important — too small and the bolt won’t pass, too large and the washer floats. The catalog also shows the graphic (777-4491) and the cover with graphic (759-3193) as a separate assembly. A generic battery hold-down kit will not match these dimensions. Use the factory part numbers and everything fits the first time.

Brake Pedal & Connections: Don’t Guess the Linkage

Brake pedal linkage on a rider like the 1105 has multiple pivot points, springs, and rods. The catalog shows 17 referenced parts on page 5. Without this diagram, you are tracing rusty pieces through a parts washer trying to figure out which spring goes where. The factory calls out every cotter pin, bushing, and clevis pin by number. If you snap a brake return spring, you order the exact spring, not something from a hardware store that might be a different rate. That matters for safety — a weak spring can cause the pedal to not return fully, leading to drag or failure. This catalog treats brakes as critical, not an afterthought.

3 Reasons to Stick with OEM Parts Documentation

First, aftermarket parts catalogs occasionally swap superseded numbers without noting it. This Cub Cadet Parts Catalog prints the original factory numbers. If a part has been superseded, the manufacturer updates the book — but you need the original as a baseline. Second, the illustrations are exploded views that show assembly order. You see which bolts pass through which washers and into which nuts. That reduces the chance of installing something backwards. Third, the catalog lists service parts (S) and production parts (P). A production part might not be available over the counter; the catalog flags that so you don’t order a part that was never sold separately. That saves a phone call.

Using This Catalog with a Torque Wrench? Not Quite – But Here’s Why It Matters

This is a parts catalog, not a service manual. You will not find torque specs on these pages. But you need correct part numbers to get the right bolts. Bolts have specific grades and threads. A 5/16-18 bolt in the battery tray (ref #2) is a grade 5 carriage bolt. If you use a grade 2 bolt, you risk it snapping under vibration. The catalog gives you the exact part — 710-0451. You look that up, get the right bolt, and then torque it per the service manual. Without the parts catalog, you might grab any 5/16 bolt from a bin and end up with the wrong thread pitch or strength. That is how things come loose. So use this catalog to pick the hardware, then use the service manual to tighten it correctly.

I have been doing this 28 years. I keep both a service manual and a parts catalog on the bench. They do different jobs. This parts catalog covers the 1105 from the air cleaner to the brake pedal — 66 pages of factory data, no guessing, no generic lists. It is printed from the original OEM file, so the part numbers match what Cub Cadet shipped. If you need similar documentation for other models, check out Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs or the Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns for more thorough coverage. The Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown also follows the same standard.

Understanding how manufacturers like Cub Cadet document parts is grounded in decades of Automotive Industry Overview practices. Factory documentation is the backbone of reliable repair. You can read more about the importance of OEM specifications in the Automotive Industry Overview. But the bottom line: if you are working on a Cub Cadet 1105, this catalog is the only parts reference you need. Access the Factory Manual now and stop guessing part numbers.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque values are not listed.

Can I use this catalog to rebuild the engine?

The catalog provides exploded views and part numbers for every component, including engine-related parts, but it does not contain step-by-step reassembly instructions. You will need a service manual for torque sequences and clearances. However, having the correct part numbers prevents ordering the wrong gaskets or bolts. That said, you can identify every engine bolt, seal, and gasket by referencing the appropriate section. It saves you from pulling a part and finding it does not match what came off. Over 80% of engine rebuild delays I have seen come from waiting on the wrong part. This catalog stops that.

Are the part numbers up to date for my 1105?

This catalog is a reproduction of the original factory document. Part numbers shown are as originally published. Some may be superseded — always check with your dealer using the number listed.

Does the catalog show wiring diagrams?

No. The catalog covers mechanical parts only — no electrical schematics or harnesses.
