Re: Ariston drum bearings stuck to spider!
The best way to do it unless you have access to a press is to place the new bearing in the bearing aperture were the seal sits and then place the old bearing on top of it and then just tap it home.
On the pulley side just line the bearing up and using the old bearing tap that one home as well.
