Do you have any ideas how I can do it right?
That pinion looks like its plastic. If it is, you will more trouble than just mounting the gear square on the shaft. I have tried plastic pinions on smooth motor shafts and it just doesn't work out very well. I had to rough up the shaft and epoxy the gear onto the shaft to prevent slipping. The only right way to install the gear would be to pull the old shaft out of the bell and replace it with a 1.5mm shaft and loctite it into the motor bell.
