If the Pro 1000 doesn't index correctly there are three common problems. The first correction to try is resetting the zero adjust screw. This is behind a semi-circular cutout along the bottom edge of the shell plate carrier. Always turn the zero adjust screw clockwise to adjust. Turn until you hear the ball bearing drop into the detent of the shell plate. Once that point is achieved, turn the screw 1/2 to 3/4 further. This insures that the shell plate stops by the ratchet under the carrier instead of the ball bearing snapping into place. If you go too far, keep turning until the next slot in the shell plate advances around to the correct position. See video on zero adjustment = https://youtu.be/ngfWHDkkBZE
If the zero adjustment will not correct the problem, the next step is to replace the hex ratchet. This is the small white plastic gear located inside the shell plate carrier. The shell plate carrier must be removed to install it (there should have been a spare included with the press). You can easily see how the old one comes out in order to determine how the new one goes on. See video on replacing hex ratchet= https://youtu.be/1o52g4wyPD0
If replacing the hex ratchet does not solve the problem, replace the drive bolt. This is the short steel bolt that holds the shell plate to the shell plate carrier and that the "actuator" rod goes through and up through the middle of the press.

The indexing mechanism on year 2023 and newer Pro 1000 has been improved so a single component controls the indexing, the driver clutch.
