Circulator fire at contact point between the brushes and armature. What is failing? What parts should be replaced?

First check your CB107 brush set. If they are too short and not making good contact with the armature you will see a lot of arching around that area. Second inspect your 612616-5 armature, especially the commutator(that is where the brushes make contact with the armature, if it looks burnt some of the small bars are darkened or raised you have a bad armature). Unfortunately the manufacture no longer supplies this part. If you really want this router working again and the armature is defective contact this link removed. And they can rewind it for you, and make better then new.
Hope this helps,
