Looking at one of the photo's close up you can see metal that has burred up and jammed it from them pressing it on so heavily. That tells me two thing: first of all those guys are sloppy, second that the chamfer on the inside diameter of the collar isn't big enough to accommodate the radius i can see on the crank.
With that said i would bet that it's not going to move towards the crank shoulder any more than that so machining the front off leavingabout 0.1mm of overhang on the face for the crank pulley and balancer to tighten down on.
Also make sure they machine back the start of the drive flats so doesn't protrude into the front seal area.
I'm bored so i put this drawing together to explain, you could give it to those drongos to fix it because it looks like they need all the help they can get.
