Cub Cadet GT2542 Parts Catalog – 85 Pages of Factory Parts Breakdowns

You’ve been there. You pull the air cleaner cover off a GT2542, find a cracked housing, and start hunting for a part number. You order something that looks right off a generic parts website. Three days later you’re holding a knob that doesn’t match, a seal that’s the wrong diameter, and you’re down another afternoon. That’s why you need the Cub Cadet GT2542 Parts Catalog. This isn’t some aftermarket reprint with blurred illustrations and mislabeled references. It’s an 85-page OEM factory document that lists every nut, gasket, bracket, and wire harness by Cub Cadet’s part number. You get exploded diagrams that show exactly how things stack together, and the S/P/F codes tell you which parts are serviceable, which are packaged with others, and which come as assemblies. Stop guessing part numbers from memory.

Air Intake and Filtration Breakdown

Page 1 of this catalog dives straight into the air intake and filtration system. Every component from the air cleaner cover kit (KH-24-743-08) down to the M6 x 1.0 x 40 screws (KH-M-651040-S) that hold the intake manifold is drawn in an exploded view. You see the precleaner element, the inner air cleaner seal, the gasket between carburetor and intake manifold. If you need the knob with seal (KH-54-755-01), the part number is right there along with the note that it includes refs 2 and 3. This is the kind of detail that stops you from ordering a knob that doesn’t have the rubber seal molded in. The catalog even calls out which base air cleaner fits the CH20S-64742 engine versus the CH20S-64748 version. That’s factory-level variation you won’t find in a generic listing.

Battery Electrical Components and Switches: Full Harness Layout

Turn to page 3 and you’re looking at the battery electrical components and switches. The main wire harness (part 629-04158) is shown with its routing to the battery, PTO clutch, engine, starter, and frame. You get the indicator/hour meter — two different part numbers depending on whether your tractor is K017 and before (725-04036A) or K017 and after (725-04022B). The ignition switch module (725-04227A), the PTO switch (725-04175), the headlight lamp (725-0963), even the fuse sizes: a 25-amp and a 5-amp. The seat switch (725-04040) and the brake interlock switch (725-3164A) are all listed. If you’re chasing an electrical gremlin, these exploded diagrams with callouts and part numbers save you the time wasted probing unknown connectors.

3 Sections That Help You Avoid Wrong Orders

Blower housing and baffles, engine cooling shrouds, and the steering assembly — the catalog breaks down these into individual pages with every screw and bracket accounted for. The blower housing section on page 5 shows the relationship between the blower housing, the baffles, and the engine mounting. You see the exact screw lengths and thread pitches. You also get the S/P/F column: S means service part (sold separately), P means it comes in a package (like the precleaner element with the air cleaner element), and F means it’s a part that’s included in a higher assembly. That column alone has saved me from ordering a part that was already inside a kit I had.

Does This Manual Cover the GT2542 2008 & Before?

Yes. The catalog is titled “GT2542 Tractor 2008 & Before.” If your machine has a serial number from that production window, every part number in this document applies. Cub Cadet issued separate catalogs for later years, so if you have a 2009 or newer GT2542, you’ll want the Cub Cadet GT2542 2009 Parts Catalog instead. The PDF bookmarks are organized by section — air intake, battery electrical, blower housing — so you jump straight to the system you’re working on without scrolling through all 85 pages.

Source Validity: OEM Cub Cadet Factory Document

This is the original Cub Cadet factory parts catalog, not a third-party scan with watermarks. The file name (CubCadet_GT2542_Parts_Catalog_en-21214001556.pdf) matches the internal OEM numbering. The pages carry the “For Discount Cub Cadet Parts Call…” header on every spread, which is standard on factory-distributed catalogs. When you access this, you’re getting the same document a dealer parts counter would pull up. That means the part numbers in the wiring harness diagram (page 3) and the intake manifold gasket references (page 1) are the actual numbers Cub Cadet used in production. No translation errors, no substituted supersessions without notice.

If you work on multiple Cub Cadet machines, check out the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs for that model or the Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns for larger equipment. These are all direct OEM prints.

Can I use this catalog to find parts for a different Cub Cadet model?

No. This catalog is specific to the GT2542 2008 & before.

Why should I buy the factory parts catalog instead of looking up parts on a generic parts site?

Generic sites often combine multiple model years or drop supersession notes. They may show a single part number for an air cleaner base when the factory catalog lists two different bases depending on the Kohler engine variant (CH20S-64742 vs. CH20S-64748). The factory catalog also includes the S/P/F codes that tell you if a part comes alone or as part of a kit. That kind of detail prevents you from ordering a $60 air cleaner cover kit when you only needed the $5 seal. Plus, the exploded diagrams show the exact orientation of brackets and hoses, which is information you never get from a text-only parts list. If you repair these machines more than once a season, the catalog pays for itself on the first order you don’t have to send back.

You need the actual part numbers in front of you, not a blurry screenshot from a forum. Access the Factory Manual and get the 85-page OEM Cub Cadet GT2542 Parts Catalog that shows every exploded view, every fastener, every harness clip. Your toolbox and your timeline will thank you.
