Hi guys, <!—-><!—-><!—->

I had to open my router to repair the switch today and found an o-ring pinched between the brushes.  I can’t seem to find where this o-ring came from.  It looks about the same size as the bearing but I just can’t find where it will fit.  Any help pointing me in the right direction would be much appreciated. (My router is a bosch 1617 series and the user manual does not include an exploded view of the assembly).<!—-><!—->
