Cub Cadet RZT50VT 2010 Parts Catalog – Factory OEM Part Numbers for B&S Engine

Ordering the wrong part because some aftermarket site swapped a reference number is a waste of your Saturday and your wallet. I’ve seen it too many times here in San Antonio. A guy brings in a Cub Cadet RZT50VT with a blown head gasket, grabs a part off a generic list, and it doesn’t fit. Then he’s down two weeks waiting for the return. The Cub Cadet RZT50VT 2010 Parts Catalog fixes that. It’s 59 pages of factory part numbers directly from Cub Cadet. Not a third-party reprint. You get the exact numbers the dealer uses.

59 Pages of Factory Part Numbers

This catalog runs 59 pages and covers the B&S 44P777-0784 engine assembly. Every page is laid out like the factory intended: a reference number, the OEM part number, quantity per assembly, and a three-letter code that tells you if it’s a service part, production part, or field replacement. Page 1 gives the exploded view of the engine. Page 2 lists components from the cylinder assembly (BS-793564) down to the oil drain plug (BS-690946). If you need the intake gasket, you’ll find it at ref 51A (BS-690950). No guesswork.

B&S 44P777-0784: Engine Assembly Coverage

The catalog focuses on the Briggs & Stratton 44P777 twin-cylinder engine used in the RZT50VT from 2010 onward. It includes the crankcase, cylinder heads (left and right), piston assemblies in standard and .020″ oversize, carburetor, flywheel, and even the idle speed kit. You get the part numbers for the short block (BS-698172) and the rotating screen (BS-494439). If you’re rebuilding the top end, you’ll need that cylinder head gasket (BS-693997) and the intake manifold gasket (BS-795123). Both are listed with S/P/F codes so you know what’s available.

Why Use the OEM Parts Catalog Over Aftermarket?

Aftermarket cross-reference lists are wrong more often than they admit. They’ll list a generic part number that looks right but the thread pitch or the gasket shape is off. This manual came from Cub Cadet. It’s the same document a dealer prints when you order at the counter. The part numbers match the factory engineering releases. If there was a supersession, the factory updates the catalog. You don’t get that with a third-party PDF that was scanned from a 2005 copy. Factory documentation follows the standards seen in the Automotive Industry Overview — consistent part numbering and traceability.

Match Part Numbers Before You Order

Before you call the dealer, pull the part number from this catalog. Look at the reference number, find the description, then confirm the S/P/F code. “/P” means it’s a production part and you can order it. “/S” means it’s a service part, may have limited availability. A few components like the connecting rod (BS-699699) are marked “/S” — those you should order in advance because the dealer may not stock them. Write down the full part number including the BS- prefix. Do not rely on memory. I’ve had guys insist they ordered “the right valve keeper” only to find it was the wrong one because they dropped a digit. The 59 pages give you the exact numbers; use them.

Source Authenticity: Factory Print from Cub Cadet

This is a genuine Cub Cadet publication, dated 2010. The original file is named CubCadet_RZT50VT_2010_Parts_Catalog_en-21214001770.pdf. It’s not a reprint or a scanned copy of a copy. You get the original factory layout with the mower’s model numbers printed at the top header. The catalog covers RZT50VT models with the B&S engine built after 2010. If you’ve got that machine, this is the right parts catalog. Similar to the Automotive Industry Overview approach to standardizing part documentation, this catalog provides a reliable reference for every nut, bolt, and gasket.

Does this catalog include torque specifications?

No. This is a parts catalog, not a repair manual. Torque values are not listed.

How do I use the S/P/F codes in this catalog?

The S/P/F column tells you the part’s availability. “S” means service part — you can order it individually. “P” means production part — normally stocked for assembly. “F” means field replacement — often a superseded number for warranty repairs. Always check the code before ordering. For example, the cylinder head gasket (BS-693997) is marked “/P”, so your dealer should have it in stock. The connecting rod (BS-699699) is “/S”, so you may need to wait for shipment. Using the wrong code leads to frustration. This catalog makes it clear, but you have to read the column.

Stop wasting time on bad part numbers. Access the Factory Manual and get the exact OEM parts for your Cub Cadet RZT50VT. That 59-page catalog is the only way to order with certainty.
