Original OEM replacement Armature Assembly used on some Makita Angle Grinders. This item includes an Armature, Fan, Commutator End Bearing. Remember to be especially careful of the armature fan when you remove it, because if you break it, you will have to replace the entire armature. Due to constant contact with Carbon Brushes armature will eventually wear out and would need to be replaced. It is highly recommended to replace both Carbon Brushes when replacing an armature.
