Cub Cadet GT3204 Parts Catalog – OEM Exploded Views & Part Numbers

Description

If you’ve spent an afternoon cross-referencing parts numbers from three different websites only to order the wrong air filter for your Cub Cadet GT3204, you know the drill. Aftermarket parts lists skip components, swap thread sizes, and omit gaskets. That’s why I keep a copy of the Cub Cadet GT3204 Parts Catalog on the bench—because when a customer brings in a tractor that won’t breathe, I need to see the exact air cleaner base gasket and know whether that M6 x 1.0 x 16 screw is supposed to be there. This 62-page manual comes straight from the factory, not some third-party reprint that guesses at part numbers.

GT3204 Air Intake Assembly: Part Numbers and Diagrams

The first section in this catalog covers the air intake system for the Cub Cadet GT3204. Page 1 lists 23 ref numbers, starting with the knob-and-seal kit (KH-54-755-01) and running through the fuel line. Every nut, screw, and seal is called out with OEM part numbers, quantities, and a service/packaging status column. You get the inner air cleaner cover part number (KH-24-096-01) and the precleaner element (KH-24-083-02) side by side. No guesswork about which wing nut fits—it’s KH-12-100-01, a 1/4-20 thread if you need to match it. That kind of detail keeps you from ordering the wrong filter base bracket (KH-24-126-21) because the diagram shows exactly where it bolts relative to the manifold.

Blower Housing and Baffles: Identifying the Right Fasteners

Moving to the blower housing section on page 3, you’ll find 13 referenced parts including the housing itself (KH-24-027-163-S) and the valley baffles. What makes this catalog useful is the fastener breakdown—M5 x 0.8 x 16 screws in three lengths, each with a specific location. The backing plates (#2 side and #1 side) have different part numbers (KH-24-146-16 and KH-24-146-20). If you’re rebuilding a GT3204 after a blown engine, you need to know which baffle goes on which cylinder barrel. The diagram on page 4 labels them explicitly: Baffle, Cyl. Barrel #2 Side (KH-24-063-20) and Baffle, Valley #1 Side (KH-24-063-59-S). This is the kind of information parts counter guys don’t have in their heads unless they’ve seen a dozen of these tractors.

Brake and Control Pedals: Navigating the Exploded View

The brake and control pedal section (starting on page 5) is a dense illustration with over 50 reference numbers. You get spring part numbers, pedal pad dimensions, and the pivot hardware. The exploded view shows the linkage order—something an aftermarket diagram would skip in favor of a generic bracket-and-pin drawing. If you’re replacing the brake return spring (KH-15-353-02 on the air intake page, but a different one on pedals), the catalog cross-references the same part number if it appears elsewhere. That saves you from buying two different springs when one part serves both the fuel line clip and the pedal return. The OEM manual doesn’t “simplify” anything—it shows every washer and clip.

How to Use a Parts Catalog vs. a Service Manual

A parts catalog tells you what goes where, not how to fix it. If you need torque specs or repair procedures, you’ll want the Cub Cadet service manual for the GT3204. But for ordering parts, this catalog is faster than any digital lookup because the exploded drawings group components by assembly. Need the intake manifold gasket? Look at the air intake page—it’s included in the manifold assembly (KH-24-164-55-S) along with two O-rings (KH-24-153-27-S). The catalog also flags superseded parts with an S in the S/P/F column, so you know when a part has been replaced by a newer version. That column alone is worth the price of admission for a shop that bills by the hour.

Source Authenticity: Factory Data vs. Aftermarket Listings

The file name tells you everything: CubCadet_GT3204_Parts_Catalog_en-21214005231.pdf. That’s a factory numbering format, not a scanned copy of a photocopy. Aftermarket parts catalogs often renumber items or leave out the “S” designation for service parts—when you order a precleaner element based on a third-party list, you might get a different density foam. This manual uses the same part numbers Cub Cadet dealers see on their screens. I’ve torn down enough tractors to know that when a part number doesn’t match the stamped number on the bracket, you’re wasting time and money. Stick with the OEM source.

Why 62 Pages Matters for a Single Model

Sixty-two pages for one tractor model might sound excessive until you realize every fastener, every seal, and every bracket gets its own line item. The GT3204 isn’t a simple lawn mower—it’s a 20-hp twin-cylinder machine with a hydrostatic transmission, and the parts count reflects that. Page 5 alone covers 50+ parts for the brake and control pedals. If you’ve ever tried to order a “brake pedal assembly” from a generic listing, you know you’ll get a box of mismatched components. This catalog gives you the individual part numbers so you can order exactly what’s broken: a backing plate, a baffle, or a specific hex flange screw. Pair it with the service manual, and you have the complete factory reference for the Cub Cadet GT3204.

Frequently Asked Questions

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. You’ll need the factory service manual for torque values, clearances, and repair procedures. The parts catalog focuses on component identification and ordering.

How many pages is this parts catalog?

62 pages.

Are the part numbers current?

Cub Cadet updates part numbers occasionally. The catalog includes the original OEM part numbers for the GT3204. Check with your dealer for superseded numbers—the S/P/F column shows service and packagings status, but the factory supersession history isn’t in this document. For most common parts, the numbers are still valid.

Can I use this manual to rebuild the engine?

The parts catalog shows you every internal engine component—pistons, rings, gaskets, seals—as exploded diagrams. You can order the correct parts, but you’ll need the factory engine service manual for assembly steps, torque specs, and clearance measurements. This catalog complements the service manual; it doesn’t replace it.
