Not much to the repair if you have a set of Torx bits and a gear puller. You can get away without the puller but you risk damaging other parts as you remove the old bearing.
To repair, remove the head by taking out the 4 Torx screws. Remove nut on end of armature ... Read more along with gear and washer. Put small puller on armature and remove whats left of your bearing... Get rid of any stray pieces in the head. Place new bearing on armature and push into place. Put washer and gear back then tighten nut to seat bearing. Put head back on and you\'re done.
Probably the trickiest part is if you pull out the entire armature as I did to check the second bearing and then have to compress the springs that hold the brushes in place. You don\'t want to crack either of them and it\'s a very tight space.
This was the first time I\'ve needed to repair my Milwaukee grinder and it took probably 40 minutes. The next time it will take 10.
