Cub Cadet i1050 Parts Catalog – 48 Pages of OEM Factory Specs

If you are elbow-deep in a 2007 Cub Cadet i1050 tractor and fighting a parts list from some third-party website, stop. I’ve seen too many guys order the wrong air filter element because they trusted a non-OEM drawing. This is the real deal: a direct PDF of the factory Cub Cadet i1050 Parts Catalog, 48 pages of exploded diagrams and part numbers that match what left the assembly line. No guessing, no cross-referencing nonsense. You get the exact Kohler part numbers, the gasket sizes, the screw lengths. That’s what you pay for.

Air Filter Intake Manifold: Page 1-2 Breakdown

The catalog opens with the air filter intake manifold section. On page 1 you get a clean diagram with reference numbers; page 2 lists the parts: intake manifold (KH-24-164-51-S), carburetor gasket (KH-24-041-52-S), intake port O-ring (KH-24-153-27-S), air cleaner base with gasket and latch (KH-32-094-04-S). Each part gets its own line with quantity, description, and a S/P/F code – Service Part, Prescribed, or Frequent. If you need an air filter element, the part is KH-32-083-03-S. That’s the factory number. Write it down. Don’t bring me some universal filter that doesn’t seat right. This catalog also tells you the flat washer (KH-X-25-63) is 1/4 inch. That matters when you’re rebuilding the whole intake system.

Blower Housing: Factory Diagrams and Part Numbers

Pages 3-4 cover the blower housing and baffles. The diagram on page 3 shows the blower housing kit (KH-32-027-03-S) which includes the air cleaner cover (Ref. 2) and the service nameplate (KH-41-037-10-S). You also get the cylinder barrel baffles – #1 side (KH-32-063-06-S) and #2 side (KH-32-063-05-S). The screw specs are right there: flange thread-forming screws M5 x 0.8 x 16, M6 x 1.0 x 16, and M5 x 0.8 x 10. If you lose a bolt, you don’t guess thread pitch. You look at the catalog. This section alone saves you a trip to the hardware store and a stripped head.

Crankcase & Crankshaft Assembly: Page 5 Coverage

Page 5 dives into the crankcase crankshaft and dipstick assembly. There are 25 reference numbers in that diagram – from the crankcase itself down to the dipstick tube. The catalog gives you every part number for the seals, bearings, and fasteners. I’ve watched mechanics try to rebuild a Kohler engine using a generic seal kit and end up with an oil leak that takes three hours to fix. With this catalog, you order the exact paper gasket or O-ring for the i1050 crankcase. That’s the difference between a one-hour job and a lost Saturday.

Parts Catalog vs. Aftermarket Parts Lists

Aftermarket parts catalogs are dangerous because they group parts from multiple model years and expect you to figure it out. This document is specific to the Cub Cadet i1050 tractor from 2007 and earlier. Every exploded view is drawn from the OEM engineering files. The part numbers start with KH- (Kohler) or the Cub Cadet prefix. When you call a dealer with a KH number, they find it instantly. When you bring me a printout from a generic site, I waste 20 minutes verifying it. The Automotive Industry Overview shows how OEM documentation drives reliability – and that applies to lawn tractors just as much as cars.

How to Use This Catalog for Repairs

You don’t read this catalog like a novel. You open the PDF, find the assembly you need (air intake, blower housing, crankcase, etc.), and locate the reference number on the diagram. Then flip to the facing page for the part number, description, and quantity. The S/P/F column tells you if the part is a service item you should keep in stock. For example, the air filter element and pre-cleaner are marked S – they wear out. The gaskets are /P – one-time use. When you order, use the exact number. If you’re working on a related model, check the Cub Cadet i1050 2008 Parts Catalog for later revisions. Similarly, the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs covers a different machine but the same level of detail. And for a larger reference, the Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns is a heavier book.

Audience Fit: Who Needs This Catalog?

If you own a 2007 Cub Cadet i1050 and do your own maintenance, you need this PDF. It’s not for someone who wants a quick fix – it’s for the guy who pulls the air cleaner, finds a split gasket, and wants to order the correct replacement without guessing. Beginners will appreciate the numbered diagrams that match what they see under the hood. Experienced techs will appreciate having the Kohler part numbers at their fingertips instead of calling the dealer and waiting on hold. The catalog also lists parts that are not always illustrated, like the service nameplate and the Cub decal – those are tucked at the bottom of page 4 with a note “Not Illustrated.” That kind of completeness keeps you from buying a decal kit that doesn’t match.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values for the i1050 are in the separate engine service manual. You need both to do the job right.

How do I verify that a part number from this catalog is still available?

Take the KH number (e.g., KH-24-164-51-S) and check it against current Kohler inventory online or call a Cub Cadet dealer. Because this catalog is from 2007, some parts may be superseded. The OEM part number is the starting point – you can then cross-reference the supersession using Kohler’s parts lookup. The Automotive Industry Overview doesn’t cover small engines, but similar supply-chain principles apply: outdated part numbers get replaced, but the original number is still the key to finding the current one. Always confirm availability before ordering.

When you’re up against a broken i1050 and you’ve got the carburetor gasket on page 2 staring at you with a part number, you stop guessing. You go to the order desk and say “KH-24-041-52-S.” That’s the sound of a professional. Access the Factory Manual now and keep that 48-page reference on your phone or laptop. It beats chasing down blurry screenshots from forum posts.
