I have a 16.5" Delta drill press (model #17-965) and I suddenly have quite a bit of vertical movement in the quill shaft - about 3/8" up and down. I'm a little stumped on how to address this so any help is appreciated. I'm attaching some pics of the shaft seated all the way up and the gap caused when its "pulled down". The second set of pics are of the forward pulley, you'll notice the shaft protrude a bit more in the one pic.

Not sure why they're coming up sideways - sorry about that.
