Both Husqvarna and Stihl make special sleeves for installing seals on the PTO side, I have some from each and they do work slick. If you're going to do much work on the type of saw you're dealing with, probably worth the few extra bucks when you place your order.
One example.

I have a few of those too, but i don't know if one is made for the 390. If one is my dealer wasn't able to find one for me.
