Cub Cadet 1772 Parts Catalog

Ordering parts for a Cub Cadet 1772? You’ve probably learned the hard way that aftermarket part numbers can send you chasing the wrong filter, the wrong washer, or the wrong belt. That’s why you need the OEM factory Parts Catalog—the same book dealership parts counters use. This is a direct scan of the original, 117 pages thick, covering serial numbers 756,300 through 799,999. Nothing generic, nothing re-drawn. You get the exact exploded views and part numbers that the engineers at Cub Cadet signed off on.

Air Cleaner & Connections: Page 1 Breakdown

Turn to page 1 and you’ll find the air cleaner assembly laid out with every clamp, hose, and mounting bracket identified. The intake assy (703-0953) and the support bracket (703-0983) are called out with their hardware—screw M8-1.25 x 20 mm (710-3137), lock washers 5/16 (736-0119), and that isomount pad (735-3021) that always cracks after a few seasons. Without the factory diagram, you’d be guessing which isolator goes where. Page 2 repeats those fastener sizes so you can cross‑check before you hit the parts counter. That’s the kind of redundancy you want in a parts book.

Air Cleaner Assembly: Exploded View Details

Pages 3 and 4 zoom into the air cleaner assembly itself. The element (KB-70000-11221) is listed with a /P suffix meaning it’s a service part you can order individually. The wing bolt (KB-15221-92620) and the gasket (KB-15221-11170) are both serviceable. I’ve seen DIY guys buy the whole air cleaner body because the parts store couldn’t find the gasket separately. That’s a waste of money—and a waste of time waiting for shipping. This manual shows you the exact part number and tells you what’s included in each assembly. The cover (KB-15241-11160) includes refs 11 and 12, but those aren’t serviced separately. You need that info before you order.

Alternator Section: Identifying Electrical Components

Starting on page 5, the alternator group shows the stator, rotor, rectifier, and all the mounting hardware. The illustration includes a voltage regulator (ref 17) and several bolts with specific thread sizes. If you’re chasing a charging issue on your 1772, you need the OEM part numbers to match what’s actually on the machine. Aftermarket catalogs sometimes source a different rectifier bracket that doesn’t line up. The factory diagram shows the correct bracket shape and the two isolator pads (refs 15–16) that keep vibration from breaking the diodes. That level of detail saves you a second trip to the dealer.

Fastener and Hardware Specifications from Page 2

Page 2 is where the catalog earns its keep. Every screw, washer, and clamp has a size and a thread pitch. The M8-1.25 x 20 mm hex cap screw (710-3137) is used on the air cleaner bracket; the 5/16″ internal/external lock washer (736-3007) shows up on multiple assemblies. Torque specs aren’t listed in a parts catalog—you’ll need the service manual for that—but the hardware dimensions let you verify that the replacement part is physically identical. I keep this catalog open on my tablet while I’m rummaging through the bolt bin. It keeps me from guessing.

Three Systems You Can Order Parts For

While the OCR sample only shows air cleaner and alternator sections, the full 117-page catalog covers the entire tractor: engine, hydrostatic transmission, steering, front axle, rear axle, PTO, and the wiring harness. Each section uses the same exploded-view format with part numbers that match Cub Cadet’s current inventory system. If you need a part for the 1772, start here. Aftermarket catalogs often skip the obscure bushings and spacers that show up in the factory diagrams. I’ve seen a steering drag link saved by a $2 bushing that wasn’t in any aftermarket book.

Source Authenticity: Why OEM Beats Aftermarket for the 1772

This Parts Catalog is a direct reproduction of the original Cub Cadet publication. No redrawn illustrations, no repackaged part numbers. The page layouts, the reference table notation (S/P/F columns for Standard-Part-Fastener), and the serial number splits are factory‑original. Aftermarket parts catalogs sometimes use generic illustrations that look like the real thing but swap a bracket or a fastener. That’s how you end up with the wrong length bolt that strips the threads in the frame. This manual eliminates that risk. It’s the same book the Cub Cadet dealer uses when he looks up your part.

FAQ

Does this manual list torque values?

No. This is a parts catalog, not a service manual. It gives part numbers and piece part identification. Torque specs are in the factory service manual.

How do I find the correct section for my 1772 serial number?

The catalog is split by serial number range 756,300 – 799,999. Inside you’ll find the same exploded-view format for every major system: engine, driveline, steering, brakes, electrical, body panels, and PTO. Each section starts with a header showing the name and the page range. Flip to the index at the back (if present) or scan the table of contents to locate your system. For example, the air cleaner section begins on page 1. If your tractor is outside that serial range, look for a separate catalog for your range. You can also check related manuals like Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs or Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns for other models. The Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown covers the smaller chassis.
