Cub Cadet 3205 Parts Catalog – OEM Factory Parts Breakdown

If you’ve ever ordered a part for a Cub Cadet 3205 Parts Catalog from a generic online listing and ended up with something that sorta fits but doesn’t, you already know why this catalog exists. I’m Mike Callahan, 28-year ASE tech. I’ve seen more mismatched parts than I’ve had hot meals. The Cub Cadet 3205 Parts Catalog is what you need sitting on your workbench or tablet when you’re hunting down a replacement.

Air Filter/Muffler Assembly: What’s on Page 2

Page 2 of this 66-page catalog breaks down the air filter and muffler system for the 3205. You get the case (KM-11011-2239), the foam element (KM-11013-2114), the main air filter element (KM-11013-2139), and the complete air filter assembly (KM-11029-2005) that includes both elements. Every part number is listed with quantity and whether it’s a service, part, or factory item. Need a muffler gasket? That’s KM-11060-2079, and you get two per pack. The exploded diagram shows exactly how the bracket (KM-11047-20579H) and hardware (bolts, collars, washers) go together. No guessing where that spring washer goes — it’s right there on the illustration.

Brake And Control Pedals – Page 3 Exploded View

Page 3 covers the brake pedal, forward/reverse pedals, and all the linkages. The catalog lists the pedal shaft assembly (603-0379), the brake shaft assembly (603-0445), and the reverse shaft assembly (603-0449). You also get the cruise control rod assembly (603-0634). The hardware list includes hex cap screws, clevis pins, internal cotter pins, and springs with their exact dimensions. For example, the compression spring (732-0324) and the torsion spring (732-0871) are both shown with their locations. If you’ve ever wrestled with pedal slop, you’ll appreciate the disengagement plate (603-0421) and clutch cam (603-0437-0637) numbers right there. That’s the difference between a working tractor and a lawn ornament.

Parts Catalog vs Service Manual – Know the Difference

This is a Parts Catalog, not a service manual. It doesn’t tell you how to rebuild the engine or set valve lash. What it does give you is every factory part number with exploded diagrams so you order the right piece the first time. The catalog groups parts by system: air filter/muffler, brake and control pedals, and more (the full table of contents isn’t listed here, but the PDF bookmarks cover the full 66 pages). Using this alongside a service manual means you won’t waste time returning wrong parts.

Why OEM Part Numbers Beat Aftermarket Cross-References

Aftermarket catalogs love to say “fits Cub Cadet 3205.” Then you get a box with a part that’s close but not exact. The thread pitch is off. The spring rate is different. The foam element is the wrong density. This catalog gives you the OEM number straight from the manufacturer. When you call a dealer with “KM-11013-2139,” they hand you the correct air filter element. No cross-referencing, no returns. That’s worth the price of the access right there. Another perspective on why factory data matters: Automotive Industry Overview.

What You Get With 66 Pages of Factory Data

Sixty-six pages of exploded diagrams, part numbers, and descriptions. Each page lists the reference number, part number, quantity, description, and whether it’s a service (S), part (P), or factory (F) item. The diagrams are clear line drawings with callouts matching the table. You can flip through and identify that missing washer or bracket in minutes. The catalog covers at least the air filter/muffler system and brake/control pedals based on the OCR data, but the full PDF likely includes the engine, drivetrain, steering, electrical, and body panels.

Frequently Asked Questions

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. It shows part numbers and exploded views. Torque specs come from the service manual.

Can I use this catalog to identify parts for my 3205 if I don’t have the serial number?

Absolutely, but you need to be careful. The catalog groups parts by system (air filter, brakes, etc.) and lists part numbers with descriptions. However, some parts changed during production. If you have a serial number range, you can cross-check. The manual includes a note ‘For Discount Cub Cadet Parts Call…’ but that’s outdated. Use the part numbers to search current suppliers. The exploded diagrams (like the brake pedal assembly on page 3) show how parts fit together. That’s critical if you’re not sure which spring or washer goes where. The catalog has 66 pages covering multiple systems. I’ve used these to order everything from a foam filter element (KM-11013-2114) to a pedal shaft assembly (603-0379). It beats guessing.
