Hey guys,

So this is the 3rd set of bearings I have replaced in this lathe in about 3 years. I can deal with that as I use it a lot. They started getting a little noisy again so I decided to change them. They are immediately noisy again. Like from the moment I put them in they are making like a growling noise at all speeds. Everything spins nice and freely and smooth buy they are terribly noisy. Also I have noticed some of what appears to be bearing grease on the spindle wheel. My main question is on tightening the spindle wheel. I have read everywhere not to overtighten it. I tighten it down and back it off about 1/8th of a turn. I cant imagine I got 2 bad bearings fresh from VXB bearings. Anyone else experience this? This lathe seems to be notorious for going through bearings.

How old is the lathe? If this is your 3rd set of bearings I would have to wonder if something else is or has gone wrong. When you start down that road it could be several things but if the bearings are brand new it doesn't seem like they're the culprit.
