Cub Cadet RZT42 2007 Parts Catalog – 40 Pages of Factory Parts Breakdown

If you’ve ever ordered a part for a Cub Cadet RZT42 and got the wrong thing—a gasket that doesn’t seal, a knob that won’t thread, a damper cylinder with different stroke length—you know the waste of time it causes. That stops the second you open this 40-page Cub Cadet RZT42 2007 Parts Catalog. This is not a reprint from some third-party aggregator. It’s the OEM document straight from the 2007 model year, scanned from the original factory print. Every part number, every reference callout, every exploded diagram is exactly what the assembly line used. You don’t guess what fits. You read the page, you order the part, you move on.

Air Intake Filtration Parts Breakdown

Page 1 of the catalog shows the air cleaner assembly for the Kohler 17AE2ACG engine. You get the part number for the cover (KH-20-096-04-S), the precleaner element (KH-20-083-03-S), and the air cleaner element (KH-20-083-02-S). The base kit (KH-20-094-01-S) includes the gasket, which is listed separately as KH-12-041-02. If you’ve ever had a dusting issue because the gasket was the wrong thickness, this is where you find the fix. The exploded view on page 1 shows exactly how the base, element, precleaner, and cover stack together. No ambiguity. No flipping between four different diagrams because someone combined model years.

What Does the Controls and Deck Lift Section Cover?

From page 3 onward, the controls and deck lift group lists 45 line items. That includes the deck lift shaft assembly (603-04160B), both lapbar levers (603-04322 RH, 603-04324 LH), the brake rod (947-04065), and the damper cylinder (727-04141). You also get every fastener—screw hex lock 1/4-20 x .62 GR5, hex cap 3/8-16 x 1.25 GR5, nut hex flange insert lock 5/16-18 GrF. If your deck lift handle is sloppy or the brake handle sticks, you find the exact shoulder screw and bearing part numbers here. This is the difference between ordering a generic “brake rod” and getting the one that matches the original assembly.

3 Key Sections for RZT42 Owners

The catalog breaks the mower into at least three major groups: Air Intake Filtration (pages 1–2), Controls and Deck Lift (pages 3–4), and Crankcase (page 5). That third section is critical for anyone rebuilding or replacing the engine block. The crankcase page lists the castings, seals, gaskets, and fasteners specific to the Kohler 17AE2ACG. If you’re chasing an oil leak from the split line, that’s the page you need. Without this catalog, you’re cross-referencing online forums and hoping the guy selling used parts has it right. With it, you have the factory part number in your hand.

Use the Part Numbers Directly to Order

Every item in this catalog includes the original Cub Cadet or Kohler part number. The reference column on each page shows whether the part is sold as an individual item (S), part of a kit (/P), or a fastener (/F). For example, the precleaner element is listed as “S” meaning stocked separately. The air cleaner base kit includes item 6 (the gasket) as a sub-component—the note says “Includes 6” right in the kit description. That level of detail prevents you from buying a base and discovering you still need the gasket. Order the kit number once, get everything. This catalog is your cheat sheet for avoiding double shipping charges and return headaches.

Crankcase Assembly: Factory Exploded Views

On page 5 the crankcase section begins. The OCR fragment shows the start of the list: reference numbers 30 and 28 are mentioned, and the page is titled “Crankcase”. While the full list isn’t visible in the excerpt, the pattern is the same as the earlier sections: factory part numbers, descriptions, and service/supply flags. If you’ve pulled the engine and need to split the crankcase for a rod or bearing replacement, this page tells you which seal, which gasket, and which bolt goes where. Without it, you’re measuring old gaskets and hoping the aftermarket kit includes what you need. With it, you order the exact factory gasket set and move on to the reassembly.

Why OEM Documentation Beats Aftermarket Lists

I’ve seen aftermarket parts catalogs that list 20 bolts when the original uses 22, or skip a washer because the typist didn’t read the diagram. This catalog came from Cub Cadet’s own publication files. The exploded views are consistent with the build sequence used at the factory. If you’ve ever tried to match a deck lift spring from a generic supplier and found it’s half an inch too short, you understand the value of an original OEM part number.

The same principles apply to lawn and garden equipment—accuracy in part numbers prevents assembly errors that lead to breakdowns.

FAQ

Does this catalog cover the 2008 RZT42 model?

No. This is strictly the 2007 model year. The 2008 uses a different engine family and chassis revisions. For 2008, see the Cub Cadet RZT42 2010 Parts Catalog (though 2010 is a different year—verify compatibility).

How do I find the right part number for my deck lift handle?

Look in the Controls and Deck Lift section starting on page 3. The deck lift handle (item 43) is part number 747-04637. If you need the grip, it’s item 23 (720-0311) or item 25 (731-04735) depending on position. Cross-check the exploded diagram to confirm orientation.

Can I use this to order engine parts?

Absolutely. The Crankcase section on page 5 covers the Kohler 17AE2ACG bottom end. For top-end parts like valves and cylinder head, you’ll need the separate Kohler engine manual—this catalog focuses on the chassis-side components.

Is there a parts list for the mower deck itself?

This catalog covers the RZT42 chassis components: air intake, controls, deck lift, and crankcase. The mower deck assembly (blades, spindles, belt) is not included in this 40-page document. For deck parts, request the separate deck assembly catalog.
