Which way to install oil seal for rotor??

Toss that bearing packer, replace it with this one. I had one of them double funnels, messy and a waste of grease. I use the heaviest grease i can buy. Usually shell. View attachment 1715780410
To pack bearing i set it in my drill press, and just use the chuck/press part to push. Not weak or lazy, i just think its way easier.
Been using one of those for many years.
