Hello experts,

After some advice fitting the 360 -1 toothed wheel.

The ID of the sprocket is considerably smaller than the OD of the crank pulley, do I simply weld the sprocket of the front of the pulley or should I machine down the pulley and fit the sprocket?

Will the second option ruin the fan belt profile?

Would an interference fit suffice? I was going to machine the pulley down, freeze it and then press fit the sprocket, slightly heated up, onto the pulley.
