Hi all,
I have a Delta 17-900 that I bought used a little while ago. I’m trying to get it set up and have encountered a couple of issues. In trying to reduce the vibration, I noticed that the motor pulley and the spindle pulley turn fine with no vibration, but the center pulley wobbles like crazy. I checked these without the belts on by hand. I assume that the bearings need to be replaced on the center pulley. I am also having a problem with runout. I’ve checked runout on just the taper and it is zero. At the tip of the chuck, runout is .004-.006, but the chuck does have a small amount of surface rust on it (from previous owner). I chucked in a 1/2″ bit and took a reading 1/2″ below the chuck tip and was getting .008. I have tried to clean the inside of the chuck (where it meets the taper) and I have cleaned the taper. Should I be looking at replacing the chuck?
Thanks,
Eric
