The shellplate carrier must be all the way down on the ram when you cinch the bolt tight.
ants, I agree that might be the case if kostyanj is indeed pushing "away" to seat the primer.
kostyanj try this - When I change the shell plate carrier (with the turret removed - you have to change the turret for caliber change any ways), I make sure the bolt is loose and use an empty primer tray (or a small piece of 2x4 or something solid) and place it on top of the shell plate vertically against the top of the press as I am pulling down on the lever to make sure the shell plate carrier is "fully" seated on top of the ram. I tighten the bolt and replace the turret with dies and Pro Auto Disk. I then check the shell plate timing.
If you are still having problem after this, you will need to disassemble the shell plate carrier and check to make sure you have the right primer rod installed (small vs large). If you take the turret off, it will make it easier to get the shell plate carrier out. Once you got the shell plate carrier out of the press, remove the center hex rod. The center hex bolt has left handed thread and will loosen "clockwise" using an Allen wrench with a Phillips screwdriver inserted in the shell plate hole to hold the shell plate in place.
Once you have the shell plate off (push the tension spring/primer push rod release arm out of the way to lift shell plate off), remove the primer feed ramp and check the primer push rod. The primer push rod needs to have the short end down with spring on top side of the rod. Your press should have come with two primer push rods (small and large). Locate the right size primer push rod and place the spring on the "long" end of the rod.
If you got the right size rod on properly in the hole with the spring, make sure you have the right size primer feed ramp (look for S or L on the side of ramp) and tighten the shell plate back on "counter-clockwise" with the Allen wrench/Phillips screw driver (don't forget the shell plate tension spring/ball). Wipe off the center hex rod with paper towel and lightly lube the rod with oil (motor oil is fine) and insert the rod into the shell plate carrier from the bottom without forcing it - let it gently glide up until the spiral twist part of the hex rod go inside the shell plate carrier.
Reinstall the shell plate carrier on top of the ram and make sure it is seated all the way down (see top of post) and tighten the bolt. Install the turret/Pro Auto Disk and check shell plate timing. Fill the primer tray with primers and install it on the primer feed ramp. Seat primer on the case by pushing "away" from you.
mine will skip a powder charge every now and then so i don't use it for the last 2 steps any longer
CHEVELLE427, make sure your chain to the Auto Disk lever arm is adjusted properly so that the disk is pulled back all the way back with each cycle of the ram lever. As long as the disk is cycling all the way back, Auto Disk should not skip a charge. Only occasions I remember when the Auto Disk did not charge were when I left slack in the chain. I adjust the chain by placing the spring in the chain and the end piece on the last chain ball. I then bring the shell plate carrier all the way down with the ram lever and pull the chain through the Auto Disk lever hole (pull through the hole in the end first and then through the other hole). The bottom of the shell plate should be barely touching the top of the spring in the chain.
Both of you, let me know how it works out.
i have 6 and so far there good.
