I was cleaning up the flywheel on my K321AS, Speck# 60373 and found a small crack at the key way (damn). I'll add it to my scrap pile. How interchangeable are these flywheels? I know the Magnum uses a bolt instead of the stud on the crank. The 1" cranks seem to have the same flywheel end as the 1 1/8" cranks. What do I need to know to get one that will work?

Thanks, Smitty

The K321 flywheel, 47 025 28-S, is common to many K241's through K341's.

I see a few flywheels off of Gravely K301 on Ebay. Would they work on my K321AS 60373?

Thanks, Smitty

This is a flywheel I'm looking at. The only difference I can see from the picture is that mine has roll pins between the magnets. This one does not. Any thoughts? Thanks Smitty

Also, I meant to say in the last post that the information Bob gave me was probably enough to answer my question, but I guess I don't know enough to figure it out from that. It's my understanding that they used different magnets depending on the ignition system. That's why I was asking about this specific flywheel.

Thanks again,

Smitty

If the seller could give you the part number of the flywheel or the engine spec number it came off you could compare them in the parts lists to see if the numbers are the same.

For yours go to
http://www.partstree.com/parts/
and type Kohler in the 2nd box and K321-60373 in the 3rd box.

So far I haven't been able to find a used flywheel with the same speck number. Is there a way to find out if any of these are interchangable?

Thanks, Smitty

Looks like your flywheel is part number 47 025 20 replaced by 47 025 28 S and then it says use 47 025 28

Go here
http://www.milacalawn.com/pages/OemParts
Select Kohler
In the Part # box enter 47 025 20 with the spaces.
The next page click on "Select Model"
What comes up are the parts lists that have that part number in them. I did not look at each one to see if there were more than one flywheel for each engine but the spec number are listed.

This is a good way to see what other models of Wheel Horse used a particular part number. Select Toro Consumer and enter a WH part number. It is what we call a reverse lookup. Be sure to read each parts page because Wheel Horse used the same parts manual for more that one model so the part you are looking for may not be used on the model you have.

You should check the other Kohler numbers as well. There may be more engines for you to chose from. Took a quick look and it shows up for some 10hp, 12hp and 14hp. That should help.

Let us know if you have trouble.

Wow! I did the search for Kohler 47 025 20.
It listed 13 different spec numbers for the K321 engines. So you're saying that I can use a flywheel from any of these spec numbers??

I searched the Toro consumer with the Wheel Horse number and only found my engine listed. I might have missed something.

Thanks you so much,

Smitty

That particular flywheel comes up under 18 spec numbers for the K-301. 20 spec numbers for the K-321, 22 spec numbers for the K-341, and 8 spec numbers that I see offhand for the K-241. I use the old fashioned, paper booklet parts manuals where specs are grouped.

While there are several specialty flywheels, by and large, the basic engines used the same flywheel. A lot of parts are interchangeable between spec numbers, and model numbers, but NOT all. That's why the spec number is still required when looking for the correct part.

Yes those spec numbers should use the same flywheel. Make sure you search the 47 025 28 for more.

I meant you to use the WH part numbers for other tractor parts. Wheel Horse did assign a part number to the engines but they are realy of no use to us. The engine manufactures themselves supported the engines meaning you had/have to go to them for service and parts.

Thanks guys! This is a bunch of spec numbers to work with. Again, I'm amazed at this resource. It sure is a different world from when I used to drive the poor guy behind the counter crazy getting him to flip through parts books. It's hard to believe that all the parts we needed could be found in those books on the counter, or a few extras down below.

Where ever you are out there in cyber land, you have my greatest appreciation.

Hope you guys aren't getting tired of me, but I'm getting closer. I've found a few flywheels, but each one has an additional letter at the end of the spec number that does not show up on my list I got from Garry's link. For example, my list shows a spec number 47723 for a K-301, but the one I'm looking at on ebay is a 47723D.

In fact of the three or four I've found on ebay, they each have a letter at the end of the spec number.

Thanks, Smitty

They only show one flywheel for 47723 so it is my guess if the D used a different flywheel it would show up in the parts list along with one for just 47723.

I think if Kohler supplied this engine in a different application with slight changes such as carb or different choke and throttle controls to suit then they added the letters at the end. At one time we could put in 2 different spec numbers and Kohler would tell us what changes had to be made to make one spec number another. Will have to check to see if this is still available.
Believe it was here
http://www.kohlerengines.com/onlinecata ... roductlist
Go into Dealers and Technicians
Then Gasoline parts lookup
Click on "I accept" and enter as a guest
Click on K-Series engines
On page 47 you will find the K301-47723 (Click on that line)
The next page is the parts list. At the top right is "Compare". That gives you the option to add a 2nd spec number for comparison.

Hope it works for you.

Garry
