sorry probably my spelling the larger pinion shouldn't be a problem. I tock a hammer and chisel and carefully put it at the back of the teeth of the pinion and gave it a light tap with the hammer and moved my way around the pinion a bit at a time, the teethe have a slight chamfer on the back so it actually makes it come out very easy.

Oh mine are completely flush with the pulley. I will give it a "bash" pun intended haha cheers

im only talking .5 of a mm chaffer but its enough to help get a sharp chisel in to start it of, once i had a small gap i could get in with a puller (in my case a few larger levers) to ease it up evenly. If you have a lathe all all the bits its probably a hours work thats all.

This shows the spacer on the shaft behind the pulley and also the bracket I made to take the hole thing crude but functional
