It's broke in half where it changes in diameter from big to small. There's 2 bearings that mount on the bottom side with a spacer in between the bearings. The top part goes thru the top pulley. The center of the "insert pulley" is hollow for a square stock of the drill press shaft spindle.
Is the hollow in the middle round or square to fit the drill press shaft spindle or is it round and the drill press shaft spindle connects to the pulley on top?
If the hollow is square then it may take a shop with a broach or something to make the square hole. (Not a machinist so I don't know what the options there are).
If that is the case it may be cheaper to have the two pieces welded together and machined down to fix it.
If it seems like a decent tool then it would be worth fixing but I have seen some really bad crap being sold in the last couple decades.
Sadly it's kind of a crap shoot.
