Cub Cadet i1042 Parts Catalog

You ever order a part for a lawn tractor blind, slap it on, and find out the air cleaner base gasket is wrong because the catalog you used had a misprint? I have. Wastes an afternoon and costs you a return shipping fee. The Cub Cadet i1042 Parts Catalog is 67 pages of the same exploded-view pages that Cub Cadet dealers pull from. Every part number, every fastener size, every gasket—it’s all there. No aftermarket guesswork, no re-drawn diagrams that skip a washer. You get the OEM layout, the way it rolled off the line. That matters when you need the exact hex flange screw M4 x 0.7 x 25 for the throttle linkage and not some “universal” substitute that strips the first time you tighten it.

I’ve been turning wrenches since 1996, and I can tell you the difference between a factory parts catalog and a third-party copy is the difference between a 1/4-20 bolt that fits and one that wobbles. Copycats leave out the “/P” or “S” identifiers that tell you if a part is serviceable or a packaged assembly. This catalog prints them. Page 2 shows the air intake & filtration group for the engine SV540-0020—includes the ref #, part number like KH-20-096-04-S for the air cleaner cover, quantity, and whether it’s sold as a single or in a pack. That level of detail keeps you from buying a whole cover when you only need the knob.

Let’s talk about the scope. This catalog covers the i1042 tractor, specifically the engine SV540-0020. It breaks down the Air Intake & Filtration, Controls, Crankcase & Crankshaft, and several other groups. Page 3 shows the Controls section with the governor spring, choke linkage, and all the little bushings that get brittle. You want to rebuild that throttle linkage without misplacing a bushing? You use this book, lay the parts out in order of the reference numbers, and cross-check the part codes before you call the dealer. The catalog also includes the engine crankcase internals. That’s stuff you need if you’re splitting the block or replacing a crankshaft seal. You don’t want to order the wrong seal—ask me how I know.

Engine SV540-0020: Air Intake & Filtration Group

This section on page 1 lists the air cleaner components from cover to base gasket. Ref #1 is the cover (part KH-20-096-04-S), #2 is the knob (KH-25-341-04-S, noted as “/P” meaning a package), #3 precleaner element, #4 air cleaner element, and #5 is the air cleaner base kit which includes the gasket (ref #6). Each part has a column: S/P/F—Service, Package, or Fastener. If you see “S” you can order that single element; “/P” means it comes in a pack. You don’t get that level of sourcing detail from a parts diagram on a generic website.

Controls Section – Throttle, Choke, and Governor

Page 3 through 4 cover the engine controls. You get the speed control assembly (KH-20-536-05-S) which includes four sub-parts, the choke linkage, throttle linkage, governor spring, and all the hardware. Notice the screw ref #7 is a hex flange thread forming screw M4 x 0.7 x 25—torque specification you’d look up in a service manual, but the part number and dimensions are here. The catalog also lists a round head square neck bolt 1/4-20 x 1” for the governor lever. That’s a specific fastener you won’t find in a bin of random bolts. If you’re rebuilding the governor, having the right part numbers saves a trip to the dealer.

3 Critical Systems Covered Beyond the Engine

While the catalog focuses heavily on the SV540-0020 engine, it also lays out the drive system, mower deck, and frame components—though the PDF bookmark data for those sections isn’t present in this excerpt, the engine breakdowns alone cover air intake, controls, crankcase, and crankshaft groups. That’s four groups for one engine. For a home garage mechanic or independent shop, that means you can order the governor spring, crankcase gaskets, and even the internal lock washer (KH-X-22-11, 1/4” internal tooth) with certainty. Aftermarket catalogs often substitute a plain washer—they skip the tooth lock. This catalog doesn’t. You get the factory spec.

Who Should Buy This Parts Catalog?

If you own a Cub Cadet i1042 and plan to keep it running past the season, you need this. I see guys on forums asking “What’s the part number for the throttle linkage bushing?” They spend hours waiting for a reply from someone who might be wrong. With 67 pages of OEM data, you open the PDF, find the Controls group, and there it is: bushing, throttle linkage, part KH-25-158-11. Done. Same for the crankcase stuff—you get the entire crankshaft assembly diagram. This manual is for the owner who wants to order parts correctly the first time, not the guy who buys three different air cleaner elements hoping one fits. It’s also for the shop technician who needs to give a customer a firm part number before they approve the repair. Saves callbacks and wasted bench time.

If you’re working on other Cub Cadet models, check these related manuals: Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs, Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns, and Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown. Each one has the same level of factory detail—no shortcuts, no re-labeled diagrams.

For context on why OEM documentation matters in the broader repair industry, see the Automotive Industry Overview and Automotive Industry Overview. Both reference the same Wikipedia article, but it’s worth reading if you want to understand how factory standards differ from generic aftermarket data.

What This Catalog Does Not Include

This is a parts catalog, not a service manual. It won’t tell you torque values or removal sequences. What it does give you is an exploded view of every subassembly with a part number that matches Cub Cadet’s inventory system. If you need repair procedures, pair this with the factory service manual. But for ordering, this is the reference. I’ve seen shops burn labor hours chasing a wrong part because they used a scanned catalog from 2008. This one is the real print.

Does this manual include repair steps or torque specs?

No. It is a parts catalog – exploded diagrams and part numbers only.

How do I use the part numbers to order correctly?

Look up the section for the engine group you need (e.g., Controls on page 3). Find the reference number in the diagram, then match it to the parts table. The part number column gives the exact code (like KH-20-096-04-S). When you call a Cub Cadet dealer or order online, give them that number. Pay attention to the S/P/F column: “S” means single, “/P” means pack, “F” means fastener. That column prevents you from ordering a 10-pack of knob covers when you only need one. If the part is listed as a kit (like the air cleaner base on page 1), the kit number includes the subcomponents. Use the list to verify all gaskets and clips are included.

You know the drill. Stop wasting money on wrong parts. Access the Factory Manual and keep the Cub Cadet i1042 running with the right pieces from the start.
