Hello, recently replaced the Armature, Brush holder and brushes in my Makita HM1317C Jack Hammer to eleviate an excessive arking issue, but it is still happening, is thete anything else I should replace
From what it looks like you’ve replaced all the elements responsible for the arking. Give it a bit of time and see if the brushes adapt.
