    hi, You are probably not going to get a good answer to your question. 1. What makes you think it is the armature(which is probably the last thing that would go wrong) 2. What if it is? You have bearings to contend with, repairs on an armature are virtually impossible for a diy guy, and if you decided to replace it the cost vs a new one is questionable as well as the fact they are spin tested for fit in each unit.

If the armature is shot, it will spark a lot where the brushes are touching the armature comutator. To remove the armature:1 Remove brushes. 2 Remove 4 screws holding the gear box. 3 Pull away gear box from the body. The armature may come with the gear box or not, it's only pushed in, so you should have no problem to disassemble it. If the armature stay in the grinder, use two skrew drivers to pray it out. You may not see anythink wrong with it, but it may be no good . That's Makita special, they don't make it good as they used to. The price for new grinder is about $130, for armature $65. field $40
