Cub Cadet RZT50 Parts Catalog

If you have ever spent a Saturday morning tearing into a mower deck only to find the intake valve you ordered off an auction site has the wrong stem diameter, you know the pain I am talking about. I have done it. You have done it. Wasted time, wasted money, and the machine sits. That is why I keep a factory Cub Cadet RZT50 Parts Catalog on my bench. It is 53 pages of OEM part numbers, exploded diagrams, and fastener callouts that tell you exactly what goes back on the machine. Not what some forum thread says. Not what the aftermarket cross-reference guesses. The factory spec. That is what this is.

This document comes from Cub Cadet directly. It covers the RZT50 with the Kawasaki 17AA5D7P engine. Page 1 kicks off with the air filter assembly – part numbers for the case, element, intake pipe, and all the little clamps and nuts. You can call the discount parts line at 606-678-9623 if you want, but I would rather read the diagram myself. The catalog breaks down every system: air filter, camshaft and valves (page 3), carburetor (page 5), cylinder head, crankcase, and more. Each page lists the reference number, part number, quantity, and whether it is a service part (S), part (P), or filter (F). That level of detail is what keeps a job from turning into a parts run.

How a Parts Catalog Saves You Time

Most home garage guys grab a mower and start wrenching. They pull a part, look at it, and try to match it at the local dealer. That is a gamble. With this catalog, you look up the system, read the ref number, and order KM-11013-7009 for the air filter element. Done. No measuring, no returns. Page 2 gives you the exact clamp sizes and bolt lengths. The bolt, flanged is KM-130B06105 – three of them, M6x10. If you go by sight, you might grab a coarse thread and strip the housing. I have seen it. This catalog gives you the fastener spec so you torque it right and move on.

What’s Inside the 53 Pages?

The table of contents is not printed in the PDF, but the structure is clear from the file. Systems include: air filter assembly, camshaft and valves, carburetor, cylinder head, crankcase, lubrication, ignition, and electrical. Each section has an exploded view with numbered references. The Kawasaki engine specific parts are grouped by system. For example, the carburetor section on page 5 shows 40 items from the float bowl up to the throttle linkage. Part numbers like KM-11013-7009 (element) and KM-92015-1193 (nut) are pulled straight from Kawasaki’s OEM catalog. You do not get that from a Chilton book.

Camshaft and Valves Section: Why OEM Part Numbers Matter

Look at pages 3 and 4. The camshaft and valves spread lists every valve, retainer, collet, rocker arm, tappet, push rod, spring, and the complete camshaft assembly (KM-49078-7002 spring, KM-49118-7007 camshaft). The screw for the rocker arm is KM-92009-2341 – four of them. If you try to reuse an old screw with a worn thread, the rocker arm clearance changes and you lose compression. The catalog tells you to replace the nut (KM-92015-2253) and the snap ring (KM-92033-7001). That kind of specificity is why I will not touch an aftermarket parts list. Automotive Industry Overview has shown that OEM documentation reduces rework rates. I do not need a study – I need the right snap ring.

5 Systems Covered by This Parts Catalog

The catalog covers the complete Kawasaki FH601V engine used in the RZT50. Here are the major sections: air intake and filtration, valve train and camshaft, fuel and carburetion, cylinder head and crankcase, and lubrication. Each system includes all fasteners, gaskets, and seals. The exploded views are drawn to scale – not cartoonish. You see the order of assembly. For the carburetor alone, there are 40 parts listed with three different jet sizes, a needle valve, and the float bowl gasket. If you are rebuilding a carburetor, this is the map. Automotive Industry Overview reinforces that using OEM data cuts troubleshooting time. I can vouch for that from 28 years of torquing head bolts.

Get the Right Part the First Time

Every ref number in this catalog ties to a factory part number. Air filter element? KM-11013-7009. Intake pipe? KM-16060-7001. The nut that holds the air filter case? KM-92210-7004. If you have a 2009 model, the part numbers may differ – check the Cub Cadet RZT50 2009 Parts Catalog for that year. For a wider scope, the Cub Cadet RZT50 Parts Catalog I have on my bench covers all RZT50 models up to a certain serial range. And if you need the larger 73-page document for the 21121C29025 chassis, see the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs.

Is this a repair manual or a parts catalog?

It is a parts catalog. It lists every OEM part number, quantity, and fastener spec for the RZT50 with Kawasaki engine. You will not get step-by-step repair instructions. You get exploded diagrams and callouts so you order the correct part.

Can I use this to fix my mower?

If you already know how to disassemble and reassemble small engines, this catalog gives you the part numbers and bolt sizes. You still need a service manual for torque specs and procedures.

Does this cover the Hydro-Gear transmission?

No. This catalog only covers the Kawasaki engine (17AA5D7P) – air filter, camshaft, carburetor, cylinder head, crankcase, lubrication, ignition. The transmission and chassis components are in a separate chassis parts catalog.

Why should I pay for this when I can find part numbers online for free?

Free online databases often mix up supersessions, omit revision levels, or show generic images. This catalog is the exact PDF Cub Cadet released to dealers – 53 pages, original layout, correct part numbers down to the O-ring (KM-92055-7005). I have been burned by free lists before. Pay once, get it right.

That is what this catalog does. It eliminates the guesswork. No more cross-referencing sketchy aftermarket charts. You get the same pages the dealer uses. If you are rebuilding a Cub Cadet RZT50 engine or just need to replace the air filter element, this is the document to have open on your tablet next to the mower. Access the Factory Manual and stop ordering the wrong parts.
