The bushing access holes are in the same location as those on the EZ-Fill base.
It will help if you pull the rack all the way out (with the operating handle in the down position) so that the powder and shot gears are rotated to their maximum clockwise position. Just moving the operating handle to the down position does not usually rotate the gears to their full clockwise position. Also the timing marks on the gears and the rack must be matched up.
You should be able to remove the bushings with the base centered by pulling the rack out to its maximum travel position.
I finally got up to Reno and put my base in. It is a noble addition to reloading. The workmanship is 2nd to none. Once I switched a couple of parts and set the Teflon screws, it screwed into place better than the OEM unit.
Hello, I'm fishing in the Bering Sea right now but I would like to order a base when I get back to Dutch Harbor at the end of this trip. Please email how you would like to be paid and address. Thanks, Brian
