I have a bfr550 autofeed that one powers up when I shake it would that be something to do with the Makita Armature ? There’s no loose wires. It seems to want to go but won’t till it’s on it’s side or shaken a bit

check your brushes

[@Davewolfy]

Great video. B helped me a lot. My grinder started smoking. I installed new brushes, and the brush holder, seems to turn in but it sounds very whizzy. Like a bit high pitched screamy. Doesn’t sound like it use to. Any ideas? Thanks have a good one

Sounds like a bearing problem to me!

[@doctorlefthandthread]

Only saw your comment and the person who commented could be correct the bearing at the end of the armature could have given up

[@Ralphfridge1]

I’ve just got one in, chunk missing from the armature, the usual melted brush holder etc.

How you change armature and gear? By pressing or how??

[@deandohertygreaser]

yes the armature comes with out the gear. so you have to press gear of the old armature.
