Edge split not working (Blender)

[Mad Rocket Scientist]

I have a problem where blender's edge split does not change the edges from sharp to smooth, but only on one cylinder.  It works fine on everything else, but when I do the exact same steps on this, it does nothing.  Auto-smooth doesn't work either.  Where it gets really weird is if I export the entire model as an OBJ, then import it into wings3d, it still will not change, even though everything else can be changed at will.

The only thing that I did differently on that cylinder that I can remember is that I followed these instructions to reduce the number of edges on it.

Does anyone have any ideas?  I really don't want to have to start over on this cylinder.

can you upload the blend file? (just include the cylinder in question if you want)

Sure: https://www.dropbox.com/s/ll0g0yltp9sb9oz/NK33.blend?dl=0

It's the turbopump assembly on the side.

The Turbopump? its because the faces are all separate. Go into edit mode, select everything, use "remove double" from the tools->mesh tools sidebar.

Thank you!  That did it.
