I recently purchased a used Bridgeport that has one shot lubrication. I noticed the other day that the knee will start to "sing" when lowering it. At first I thought the vertical ways weren't getting any way oil from the one shot system. But after removing the ends of the lines feeding each of the vertical ways and giving the one shot a pump, way oil is definitely coming out of both lines (I did this one at a time on each side of the knee). Also there is a thin coat of way oil on the vertical ways as well.
After doing some searching on here, I found a couple of threads indicating that the "singing" could be coming from the screw and not the ways. In one post someone mentioned putting some way oil on the screw. So I raised the knee all the way up and noticed there is a zerk fitting at the base of the screw. I can't find anything in the manual for this fitting. I am assuming this would be a way oil zerk fitting instead of grease similar to what would have been on the ways prior to the one shot system?
