Mill has been shut down for a few weeks....fired it up today and warmed up the spindle....it is making a very noticeable sound coming from the lower motor area..It sounds bearing related - we all know the sound of a failing bearing... I know it isn't the spindle bearings - they sound OK.... It could be a tensioner bearing or the lower motor housing bearing...
Anyone have something like this happen? How bad is replacing a motor housing bearing? Anything special to putting the motor back on after removing?
Thanks!
