Cub Cadet 2160 Parts Catalog – 68 Pages of Factory Part Numbers

You are in the middle of a transmission rebuild on a Cub Cadet 2160 and the exploded view from some aftermarket website shows a 27T drive gear that does not match your machine. You waste an hour cross-referencing. That stops with this Parts Catalog. It is the exact OEM document that the dealer uses – 68 pages of factory-coded part numbers, serial number breaks, and assembly groupings. No guesswork.

The serial range on this catalog is 239,001 through 326,005. That means if your tractor falls within those numbers, every part listed here is the exact one from the factory. The transmission is a 6-speed unit, and the catalog breaks it down into subsystems – axle housings, differential, gear sets, shift collars, and fasteners with specific part numbers and quantities. Page 2 alone shows the left-hand axle assembly with part number 611-3008, oil seal 721-3020, and the exact screws (710-1008 vs 710-3236) depending on your transmission serial number. That level of detail keeps you from ordering the wrong hardware.

6-Speed Transmission Breakdown – What This Catalog Covers

This is not a repair manual. There are zero torque specs, no maintenance schedules. What you get is a part-number-level breakdown of the 6-speed transmission, the front axle, and the chassis components. The catalog groups parts by assembly: left and right axle housings, differential housing, shift mechanism (collars, keys, spacers), and the entire gear train from first gear (58T) through sixth gear (27T drive). Each group includes part numbers, quantities, and notes like “S/P/F” (Service Part, Packaged, Factory) so you know availability. For example, the neutral spacer (750-0991) is marked /P meaning it is packaged individually. If you are rebuilding a transmission that has serial number 005793 and above, you need housing 619-3037 and the longer screw; below that, the older housing 619-3008. This catalog makes that distinction clear.

Axle Housing Assembly – LH Side Detail (Page 2)

Page 2 lists 42 line items for the left side of the transmission alone. The LH axle assembly (611-3008) is the starting point. You will see the oil seal (721-3020) marked with an S – that means it is a service part you can order separately. The bearing (741-3033A) is also a service item. The catalog calls out two different hex cap lock screws depending on transmission serial number: 710-1008 (3/8-16 x 1.88) for units above 005793, and 710-3236 (3/8-16 x 1.75) for below 005792. Miss that detail and you either strip the thread or have a loose housing. This is why you want the factory print, not a re-drawn aftermarket diagram.

Gear Set and Shift Mechanism – 17 Separate Gears

The 6-speed transmission uses a constant-mesh layout with shift collars engaging specific gears. The catalog lists each gear with its tooth count: first gear is 58T on the shift side (717-3362), second is 40T (717-3361), third 27T (717-3360), fourth 24T (717-3359), fifth 22T (717-3358), and sixth 18T (717-3357). On the drive side you have 27T sixth drive (717-3353), 23T fifth (717-3354), 20T fourth (717-3344), 17T third (717-3351), 15T second (717-3352), and the drive shaft with first gear integrated (717-3349). The shift collars (left and right, 718-3029 and 718-3028) ride on a key shifter arm (718-3021) with spacers and springs. If you are chasing a gear pop-out or hard shifting, the neutral spacer (750-0991) and shift key spacer (718-3030) are the parts to inspect. This catalog gives you the exact numbers to order from any Cub Cadet dealer.

Who Needs This Parts Catalog?

Home mechanics who bought a used 2160 and want to refresh the transmission. Small engine shops that need to quote a transmission rebuild accurately without hunting down serial numbers. Anyone who has been burned by a parts house sending a 20T gear when you needed a 17T. This catalog is for the person who wants to open the transmission once, lay out every part, and order everything in one shot. It is also useful if you are piecing together a parts tractor – you can identify exactly what is missing. If you work on these tractors regularly, pair this with Cub Cadet 2160 Parts Catalog – same document, different format – and the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs for the larger frame models. The Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns also covers the earlier gear-drive tractors.

Source Validity – OEM vs Aftermarket Catalogs

I have seen aftermarket parts catalogs that combine two different serial number ranges into one drawing, and you end up with a part that does not fit. This document came straight from the Cub Cadet dealer network. The page watermark shows “www.mymowerparts.com” with a phone number for ordering, but the content is the original factory print. Each part number follows the Cub Cadet/OEM numbering convention (e.g., 611-3008 for the axle assembly). The 68 pages contain no third-party redrawing – it is scanned from the original. If you need to verify the Automotive Industry Overview, that is outside the scope. Automotive Industry Overview is a general reference, but for this tractor, the factory catalog is your only reliable source.

FAQ

Does this catalog include torque specifications for the transmission bolts?

No. This is a parts catalog, not a repair manual. It lists part numbers, quantities, and assembly groupings. You will need a separate service manual for torque values.

Will this catalog work for a Cub Cadet 2160 with serial number outside the listed range?

The catalog is explicitly for serial numbers 239,001 through 326,005. Tractors outside that range, especially older ones, may have different axle housings, gear sets, or shift mechanisms. For example, transmission serial numbers below 005792 use a different left-hand differential housing (619-3008) and shorter screws. Using this catalog for a different serial range risks ordering the wrong parts. Measure your existing parts and compare to the exploded views before ordering.

If you are rebuilding a 6-speed transmission on a Cub Cadet 2160, do not guess part numbers. Access the Factory Manual – the same 68-page OEM catalog that dealers use – and get the exact parts the first time.
