worked great. i used this on a sears snowblower to replace a sprocket that was no longer available from sears.i had to make the bore larger and drill some holes to bolt it on. this sprocket was exactly what i was looking for.

I used this to adapt a 3 wheeler axle to a go kart that I was building. Had to bore the center to 2 3/4" and drill holes for the mounting bolts. Worked great!
