Do you mean a 36-1 tooth wheel?

You can do it any way you want.

Some guys weld, screw, or expoxy the 36-1 to the original crank pulley.

Others machine it to fit the snout.

Yet others machine the 36-1 to fit on the original crank pulley, and use an interference fit.

I bolted mine to the crankshaft, not welded or attached to any pulley. Used a bushing since the 36-1 pulley I.D. was larger than the crank bolt.
