Cub Cadet 1615 Parts Catalog

You get a mower in the bay with a fuel leak. You need the right carburetor gasket. You pull up a generic parts diagram from some random site, order what you think fits, and end up with a gasket that’s half an inch too small. I’ve seen it happen a dozen times. That’s why the Cub Cadet 1615 Parts Catalog sits on my bench, not some third-party PDF scraped together from eBay listings. This is 73 pages of OEM documentation—direct from Cub Cadet, not a photocopy of a copy. It shows every nut, washer, and seal with its factory part number, quantity, and serviceability status. You get exploded views that match the actual assembly. No guesswork.

Air Cleaner Assembly: Full Parts List with 15 Ref Numbers

Page 1 of this catalog breaks down the entire air cleaner assembly into 15 individual reference numbers. Each one has a corresponding part number, description, and quantity. For example, Ref #5 is part number KH-45-083-01, the precleaner, with a quantity of 1 and marked as a service part (S). Ref #4 is the cover, listed as a purchase part (/P). That distinction—S/P/F—tells you whether to stock it or replace it as an assembly. I’ve had techs try to order a whole base because they couldn’t read the column. Don’t be that guy. The wing nut (Ref #1, KH-X-276-7) is a simple item, but without the correct part number you’ll waste an afternoon matching threads at the hardware store.

That’s the difference OEM documentation makes.

Battery and Mounting: Page 3-4 Details

The battery section covers the 12-volt battery (part 725-3061) plus the tray, rods, cover, and hardware. You get the bolt part numbers: 710-0451 for the carriage bolt (5/16-18 x 0.75 inch) and 710-3008 for the hex bolt. The catalog lists lock washers, wing nuts, and even the battery drain hose—48 inches long, part 735-3027. If you’re replacing a battery tray, you don’t need to measure. You look up the reference number and order the exact part. That saves a return trip to the dealer.

Brake Pedal Connections: OEM Part Numbers

Page 5 shows the brake pedal linkage with 17 reference numbers. The layout is clean: a line drawing with callouts, then a table listing each part number and description. You’ll find the pedal rod, springs, bolts, and nuts. Again, the S/P/F indicator tells you if the part is available separately or only as part of a larger assembly. This is the kind of data you need when a customer brings in a 1615 with a broken pedal spring. You pull the catalog, find the spring part number, order it, and you’re done. No eyeballing the length, no making one from a random spring off the shelf.

73 Pages: What This Catalog Covers

This isn’t a repair manual. It’s a parts catalog. The 73 pages cover the entire Cub Cadet 1615—engine components, chassis, body panels, electrical, and more. The three sections I referenced above are just the ones I’ve needed most often. Each page follows the same format: a clear exploded diagram and a table with reference numbers, part numbers, quantities, and the S/P/F column. If you need to know the difference between the left and right battery cover rods (Ref #4 and #5 on page 4), it’s right there. The catalog cross-references the illustrations to the part numbers so you don’t order the wrong one.

Why OEM Documentation Beats Third-Party Reprints

Aftermarket catalogs often rearrange diagrams or omit the S/P/F column. They might use generic bolt descriptions instead of the actual Cub Cadet part number. That means you order a “5/16” bolt from the generic list and get one with the wrong thread pitch. I’ve wasted hours matching threads from a parts store bin because someone bought a cheap PDF. This catalog is an original OEM print. The part numbers on page 1 match Cub Cadet’s inventory system. You call them, you give the number, you get the right part. Period.

FAQ

Can I use this catalog to identify parts for other Cub Cadet models?

No. The 1615 catalog is specific to that model.

Does the catalog include torque specifications for the bolts it lists?

No. This is a parts catalog, not a service manual. It lists hardware part numbers and quantities but does not provide torque values. However, the S/P/F column tells you if a bolt is a service part you can replace individually, which implies you need the correct torque when reinstalling. For actual torque specs, you’ll need the factory service manual for the Cub Cadet 1615. That said, having the exact bolt grade and size from this catalog allows you to find the correct torque in the service manual without guessing based on generic charts. It’s a complementary tool. If you’re doing a full engine rebuild, you need both documents.

Every time I’ve used a third-party parts list, I’ve regretted it. Wrong part numbers, missing hardware quantities, diagrams that don’t match. The Cub Cadet 1615 Parts Catalog is the only reference I trust when ordering parts for this machine. If you work on these mowers, you need this on your bench. Access the Factory Manual now.
