Cub Cadet 2518-48 Parts Catalog – 90 Pages of Factory Parts Breakdown

I’ve been turning wrenches for twenty-eight years, and I still see it happen: a guy tears down his mower, heads to the parts counter with a handful of bolts, and ends up buying the wrong spindle because he used a generic parts list from some forum. That waste of time – and your own money – stops the second you open the Cub Cadet 2518-48 Parts Catalog. This is the same 90-page document the dealer uses. Factory exploded views, OEM part numbers, and the exact fasteners for every assembly on the tractor. Nothing from a third-party reprint house.

48-Inch Deck Assembly Breakdown

The heart of this catalog is the 48-inch deck – page 2 alone lists 71 reference numbers for that assembly. You get the caster wheel bracket (603-0031A-0716), the RH and LH front spindle assemblies (603-0110 and 603-0111), and every spring, guard, and baffle. Need the tension handle? 603-04113-0716. The belt guards? 703-2096B-0716 and 703-3240-0716. When you call a dealer to order, you read them the factory number – not a description that could be three different parts. That’s the difference between one trip to the parts store and three.

Why You Need OEM Part Numbers

Aftermarket catalogs will often combine several model years into one drawing. They’ll show a generic “spindle assembly” that fits ten different decks, but it won’t match your bolt pattern. This Parts Catalog is model-specific to the 2518-48 tractor. Every part number listed – like the 703-2248-0716 front lift bracket or the 703-2081A-0716 LH caster channel – is what Cub Cadet stamped on the original part. If you’re rebuilding the deck, you need those exact numbers to get the correct shoulder bolt lengths and thread pitches. The wrong cap screw (see 710-0347, 3/8-16 x 1.75 GR5) can strip the casting. This catalog stops that before you torque anything.

3 Reasons Aftermarket Catalogs Cost You Money

First, they skip fastener details. The factory catalog tells you the grade (GR5), thread size, and length for every bolt. Second, they don’t show supersessions – notice on page 2, the tension handle was replaced by 603-04113-0716. You’d never see that in a generic list. Third, they omit the “S/P/F” column that tells you if the part is a service part, production part, or both. Without that, you might order a production-only piece that isn’t stocked anymore. Stick with the factory document.

Get the Right Fastener the First Time

Look at the hardware list on page 2. The catalog calls out a thumb adjustment screw (710-3232, 5/16-18 x 1), a carriage bolt (710-3178, 3/8-16 x .75 GR5), and a hex flanged lock nut (912-0431, 3/8-16). You need 24 of those carriage bolts for the deck mounting. If you grab a standard hex bolt instead, the square shoulder won’t lock into the slot, and the whole deck shifts when you mow on a slope. This catalog gives you the exact fastener count and type. No guessing, no returns, no downtime while you wait for the right part to arrive by mail.

Spindle Assemblies and Caster Wheels

The front spindles (RH 603-0110, LH 603-0111) are separate assemblies with their own bearing and seal specs – though the catalog doesn’t list overhaul details, it does give you the complete assembly part numbers. The caster wheels (703-1890A, 5-inch ball wheel with lube fitting) are shown with the lube fitting 937-3000. If you’ve got a worn caster, you order the whole wheel assembly, not just the tire. The exploded drawings make it obvious where every snap ring and spacer goes. For a beginner working in a home garage, this visual reference is the difference between a successful repair and a pile of parts you can’t reassemble.

Source Authenticity: OEM vs. Aftermarket

This is an original factory document – not a scanned copy of a copy, and not a compilation from a subscription website. The page headers read “For Discount Cub Cadet Parts Call 606-678-9623 or 606-561-4983” – that’s how the factory supplied it to dealers. The part numbers match what Cub Cadet still uses today. I’ve seen too many DIYers burn an hour cross-referencing a generic part number that doesn’t exist. Don’t be that guy. Use the real thing.

Frequently Asked Questions

Does this catalog include engine or electrical parts?

No. It covers chassis, deck, and drivetrain components only. The engine and wiring are separate manuals.

How do I use the reference numbers to order parts?

Each assembly has a list with a reference number (e.g., Ref 1 for caster wheel bracket), the factory part number (603-0031A-0716), quantity, and description. You take that part number to a Cub Cadet dealer or online parts retailer. The catalog also notes supersessions – for example, the hinge pin changed from 711-3318 to 711-1762 after November 19, 2001. If you just give the description “hinge pin,” you might get the wrong length. Use the number, check the date code on your tractor, and you’ll get the correct part. That level of detail is why factory catalogs exist.

Stop ordering parts blind. Access the Factory Manual and start every repair with the right part number in your hand.
