Folks,

I've been working on a used TSV-35 tapping center that I recently purchased. I have most things pretty well dialed in, but one last thing that has me a bit puzzled is how the spindle bearings are supposed to be lubricated. I had to pull the spindle and ship it out to have the taper chromed and ground. During that process, I got a good look at the top end of the spindle and the bearings don't have seals installed. This leads me to believe that they should be receiving oil lubrication somehow, but I don't see any ihint of where an oil cup is/was located, there isn't an inline oiler for oil mist, and there is no mention of anything in the manual.

If someone else on the forums has one of these in operation, could you share how the spindle bearings are lubricated? It's a 6000 RPM max spindle, so it's possible that the bearings were supposed to be packed and sealed and that someone pulled the seal along the way, but I'd like to know for sure.

Thanks!
