Has anybody here replaced the lower bearing in their ER11 router, we have about 100hrs on ours and it started making sounds that were not normal, we dissembled it and figured out that the lower bearing is shot (has friction in it creating sounds not normal to regular operations). Upon looking in the manual it tells me it is a NSK 6003 DD bearing which only has a recommended max speed of 13000rpm which seems low for a router designed for up to 32000 rpm. has anybody upgraded this bearing and how the heck do you get it off to replace it
