Yes if it is a rim sprocket you just need to change the rim.
I don't think a .404 even came in the small spline but check to make sure the new rim and the old rim are the same drive size.

I agree Mike. I'm guessing the .404-7 rim Scott speaks of is on his Dayton badged 245. They seem to have come with .404 quite often.
If I remember correctly the 3/8 and .404 rims should fit your drum. Make sure if you have a sprocket tip bar that you change it when changing the rim, roller nose and hard nose bars do not discriminate against chain size, just make sure you have the proper gauge.
Yes it is a Power sharp.Only the Dayton with Power sharp version came with .404 as far as I know and have seen so far.
So yes a standard 3/8s rim can be used on that clutch drum.
Thanks guys, I forgot that I had a 3/8 rim off of a Craftsman 3.7.Took the clutch back off the Dayton and slipped right on. Now the b/c fits great.
