Cub Cadet 5252E Parts Catalog – 71 Pages of Factory Specs

Cub Cadet 5252E Parts Catalog – 71 pages of OEM factory part numbers and exploded diagrams that tell you exactly what goes where and what bolt goes in what hole. I’ve been turning wrenches since before some of you were born, and I can tell you the difference between a genuine factory parts catalog and some aftermarket knock-off is the difference between a straight six and a lawnmower engine. You want the right part the first time? You buy the book that the dealer uses. This is that book.

Page 2 lays out the 2WD transmission connections with every reference number, part number, quantity, and description for things like the hydrostatic transmission pump, cooling fan, check valve, and the Loctite sealant PN 759-3958. Need a shoulder screw for the hydro arm? It’s 710-04040. The guy who answers the phone at a Cub Cadet parts counter (606-678-9623 or 606-561-4983) reads off this exact catalog.

That phone number is printed on the cover of the original PDF – that’s how you know it’s the real deal. Not a reprint. Not a scan. The original OEM document.

Transmission Connections: Page 2 Details

The 2WD transmission breakdown on page 2 covers 48 individual components. Ref #22 is the hydrostatic transmission pump, #44 is the hydro pump filter (part BS-492932S), #45 is the check valve set at 30 PSI. The catalog gives you the spring extension specs (0.50 x 1.975 x 0.072) and the washer lock sizes – 5/16 lock washer, part 736-0119. If you’re rebuilding a transmission or chasing a leak, you need this page open on your bench. I’ve seen guys guess at an O-ring size and end up with a puddle of oil on the shop floor. Guesswork costs time and money.

Air Intake System: Page 3 Exploded View

Page 3 covers the air intake assembly for the Kohler engine. Ref #2 is the cover knob, #3 is the seal – they come as a kit (KH-54-755-01-S). The air intake chapter includes the filter housing, gaskets, and mounting hardware. If you’re chasing a lean condition or a dirt-ingested engine, start here. The correct part numbers prevent you from ordering the wrong filter base or missing that little plastic clip that breaks every time.

Parts Catalog vs. Service Manual – Know the Difference

This is a parts catalog, not a service manual. It tells you what parts go into your machine, not how to rebuild the engine. If you need step-by-step repair procedures, look for the Cub Cadet 5252E service manual. But if you’re ordering parts, quoting a job, or confirming a fastener size, this catalog is the final word. The exploded views show you every nut, bolt, washer, and seal. I keep both on my tablet.

3 Reasons to Use OEM Documentation for Your 5252E

• Part numbers are verified at the factory – no “interchange” guesses. The transmission oil part number 737-3120 (1 qt) or 737-3121 (1 gal) is what Cub Cadet ships.
• Exploded diagrams show assembly order – helps you avoid putting the Belleville washer (736-0331) backwards.
• Torque and thread specs are printed (e.g., hex cap screw 1/4-28 x 1.0 GR5, part 710-0299) so you know exactly what fastener to grab.

Does This Manual Cover the Fuel System?

The 71 pages cover the engine, transmission, air intake, and chassis components. The fuel system is not shown in the available bookmarks, but if your 5252E has a Kohler engine, the fuel pump and carburetor parts are typically listed in the engine section. You can cross-reference the Kohler engine parts catalog for that. For transmission, air intake, and chassis – this is your source.

Source Validity – This is an OEM Factory Document

The PDF title is CubCadet_5252E_Parts_Catalog_en-21214001553.pdf. That number is the factory document ID. The cover page includes a parts ordering phone number and the “S/N 1J015G & After” serial number range. No aftermarket publisher would include a dealer’s phone number like that. This is the same catalog the Cub Cadet dealer uses to look up parts when you call. Automotive Industry Overview is relevant if you want to understand how OEM documentation standards protect both the manufacturer and the mechanic.

Frequently Asked Questions

Do these pages include wiring diagrams?

No. This is a parts catalog, not a wiring manual. Exploded views show mechanical parts only. Wire harness assemblies may appear as a part number, but you won’t find a schematic.

Can I use this to rebuild my hydrostatic transmission?

Yes – the transmission connections section (page 2) lists every O-ring, seal, pump, and cooling fan. You’ll get part numbers for the pump (718-04141), fan (731-05247), and fittings. Rebuilding without this list means you’ll end up with leftover parts. Order the gasket set separately.

What years does this cover?

Covers S/N 1J015G and after. That’s a specific production run. Check your serial number. If your tractor is older, you need a different catalog.

How many pages are in this part number list?

71 pages.

Look, I’ve seen guys spend three hours on the phone trying to find a hydro filter because they didn’t have the part number. That filter (BS-492932S) is right there on page 2. Access the Factory Manual and keep it in your shop tablet. It’s 71 pages – small enough to print and put in a binder, detailed enough to save your weekend.
