Hi, just wondered if there was a way of removing this bearing intact as I want to replace the small mag seal & obviously this bearing is in the way :? I have tried in the past but have never been successful & have always ended up having to fit a new bearing :( any info greatly appreciated ;)

I remove the circlip and seal, clean out the grease and heat the mag housing with a blow lamp (not excessively) and then with a gloved hand bring the mag housing down on a block of wood. There will be several other method but this works well for me.

Heat is your friend here. Just be sure to not let the bearing hit the ground or anything hard.

Keep in mind this only works if the magflange isn't beat to s**t. I've had a couple where no amount of heat would let the bearing drop out. I'm not even sure how they went together they were so tight.
