Cub Cadet RZT42 Parts Catalog

Back from a job where a guy brought in an RZT42 with a carburetor that had been “rebuilt” using aftermarket gaskets. Three weeks later it was leaking fuel onto the exhaust manifold. I spent an hour chasing down the correct float bowl gasket because his parts catalog was a photocopy of a photocopy. That’s the difference between a real Cub Cadet RZT42 Parts Catalog and some third-party PDF. This one runs 45 pages, factory-original, with every exploded view and part number printed from the OEM file. No guesswork.

Carburetor, Air Cleaner, and Manifold Breakdown

Pages 1 and 2 of this catalog cover the B&S Intek carburetor system in detail. Every ref number ties to an OEM part number. Need the intake manifold gasket? That’s BS-692137. Float bowl seal? BS-281165. The exploded view shows you exactly how the throttle shaft bushing (BS-690602) fits inside the carb body. I’ve seen techs install the choke valve (BS-690464) upside down because they were working from a generic diagram. That doesn’t happen when you’re looking at the factory layout. The catalog lists standard and high-altitude main jets (BS-694352 and BS-697228) so you don’t guess which one to order for Texas summers.

Controls and Deck Lift: Part Numbers That Fit

Deck lift arms on the RZT42 come in two hole sizes – 1/4-inch and 5/16-inch. The parts catalog lists both: item 7, part 703-05401 (1/4″ hole) and 703-05793 (5/16″ hole). If you order blindly, you’ll get the wrong one and spend a Saturday fighting with mismatched hardware. Lapbar levers, brake handles, front deck hanger rods – all with factory part numbers and quantities. This is the kind of detail that separates a one-hour job from a three-hour headache. You want to know which bracket takes a 710-0xxx bolt? It’s all in those 45 pages.

Why OEM Part Numbers Save Your Weekend

Aftermarket parts catalogs renumber things. Sometimes they cross-reference wrong. I’ve seen a “universal” float kit that left out the needle valve seat. The Cub Cadet RZT42 Parts Catalog gives you the genuine BS-231855 float needle valve, the BS-690577 inlet seal, and the BS-691333 limiter cap. Every gasket, O-ring, and seal has a factory suffix – S for service part, P for package, F for fleet. You order BS-692138 O-ring seal and it arrives the right diameter. That’s not luck. That’s OEM documentation. Automotive Industry Overview Automotive Industry Overview reminds us that proper parts sourcing is the foundation of safe repairs.

Audience: Who Needs This 45-Page Parts Catalog?

Home garage guys who own a Cub Cadet RZT42 and want to do their own maintenance. Small engine shops that see a dozen of these mowers each season. Anyone who has ever ordered a “close enough” carb gasket and watched the engine run lean. If you’re rebuilding the B&S Intek carburetor, you need the exact jet sizes and gasket thickness. This catalog gives you that. The exploded views are clear enough that a beginner can identify a throttle shaft kit (BS-495097) without calling a dealer. 45 pages is not overwhelming – it’s the right amount of detail for one specific machine. No fluff, no reprints.

Source Authenticity: Factory Print vs Aftermarket

This is an original OEM file, not a scanned and recopied version where the part numbers are blurry. The file name is CubCadet_RZT42_Parts_Catalog_en-21214001734.pdf. That’s the factory code. I’ve seen aftermarket catalogs that swap part numbers or omit the “S/P/F” flags. This one has all of them. For the deck lift shaft assembly, the note says “also furnish (2) 759-04085” – that auxiliary part number is easy to miss in a third-party document. Here it’s right there. If you’re serious about getting the correct bolt for the blower housing (BS-697102 and BS-697103, different lengths), you want the factory source.

Frequently Asked Questions

Is this manual a repair manual or just a parts list?

It is a parts catalog. No step-by-step repair instructions. It gives you exploded views and OEM part numbers so you can order the correct components for your RZT42.

Can I use this to rebuild the B&S Intek engine completely?

The catalog focuses on the carburetor, air cleaner, manifold, controls, and deck lift sections. It does not include internal engine components like pistons, rings, or crankshaft. For a full engine rebuild you would need an engine-specific service manual. However, for the external fuel and control systems, the part numbers are complete and accurate. If you are replacing the carburetor (BS-698445) or the float bowl (BS-495933), this catalog tells you exactly which gaskets and seals to order. It also cross-references the high-altitude jet if you operate above 5,000 feet. For the deck lift system, you get the left and right lapbar levers (603-04150 and 603-04181A) and the front hanger rod (747-04223A). It is a focused reference for the RZT42-specific assemblies. Combine it with an engine service manual for a full teardown.
