nso123 Posted August 2, 2019 Share Posted August 2, 2019 I was running a batch of 9mm on my 650XL tonight and on the downstroke it suddenly felt like the whole press tightened up. After doing a few shorter strokes, things loosened up, but the primers stopped feeding. I took the primer assembly apart and cleaned and lubed it, but it didn't correct the issue. Now it appears that the disc is indexing about half of the correct amount now, as it is properly indexed on every second stroke. It almost seems like the indexing arm isn't grabbing the disc in the right position. Does this sound like a quick fix, or does it sound like I need parts?

Sarge Posted August 2, 2019 Share Posted August 2, 2019 How far apart did you take it. My 650 locked up completely once and the entire Assy was caked solid with crud Link to comment Share on other sites More sharing options...
nso123 Posted August 2, 2019 Author Share Posted August 2, 2019 I took the entire priming assembly apart and cleaned and lubed it. I also took the primer eater out and cleaned it. Same thing with the shell plate. It is almost like the index arm is not moving in the correct plane and binding the spring. It makes me wonder if something may have bent when it suddenly tightened up and it is causing the index arm to not move properly. Link to comment Share on other sites More sharing options...
Sarge Posted August 2, 2019 Share Posted August 2, 2019 It’s fairly fragile if you forced it much. Do you have a spare parts kit to compare parts with? Maybe take a pic of the Assy and post it for us to look at. Something is probably bent Link to comment Share on other sites More sharing options...
rodell Posted August 2, 2019 Share Posted August 2, 2019 (edited) When this happens to me there is often a primer (or piece of one) that kept going around with each stroke until it jams. It gets tighter and tighter as it gets wedged into the primer assembly. The index arm can also be bent, which means the return spring sets at an angle. Take it out and look at it - it should be straight and not bent upwards. Edited August 2, 2019 by rodell Link to comment Share on other sites More sharing options...
Balakay Posted August 2, 2019 Share Posted August 2, 2019 change the indexing arm spring. Whenever the arm starts missing the holes on the disk, this seems to be the problem on my 650 Link to comment Share on other sites More sharing options...

nso123 Posted August 2, 2019 Author Share Posted August 2, 2019 Thanks for the suggestions. I don't have a spare arm or spring, but I think I can get one locally. It is definitely at an angle now, so that sounds like it may be the issue. Link to comment Share on other sites More sharing options...
rodell Posted August 2, 2019 Share Posted August 2, 2019 If the arm is bent, you can bend it back without a problem until you get a spare. Link to comment Share on other sites More sharing options...

Take it out and look at it - it should be straight and not bent upwards. This just happened to me, found a small piece of primer brass or crimp ring that fell out when I took it apart. Bent the arm, once replaced it worked fine. Happened using range brass, pretty sure it is crimped/sealed Winchester Nato type brass. Has a crimp ring, not sure if it was the crimp ring or a piece of the primer that stuck in the primer plate opening and jammed it. If I feel resistance now I stop immediately without forcing the arm and take the primer assembly apart to prevent the primer advance arm from bending. I keep a spare around. gerritm Link to comment Share on other sites More sharing options...

Whenever the arm starts missing the holes on the disk, this seems to be the problem on my 650 Yes. The spring will lose it's power over time. I've also had a couple break. The arm can also develop problems and both issues will result in the behavior you describe. Call Dillon, describe the problem, they will most likely send you both a new spring and a new arm. Ask them to send you a couple of springs so you have a backup. They most likely will have no problem with that request. Link to comment Share on other sites More sharing options...
Nathanb Posted August 2, 2019 Share Posted August 2, 2019 Also check your primer disk to make sure it’s still flat. I had this happen and found that my disk was warped at some point. Link to comment Share on other sites More sharing options...
Furrly Posted August 2, 2019 Share Posted August 2, 2019 Dillion will send you replacement parts.. Takes about 4 to 5 working days to get parts depends where you are located Link to comment Share on other sites More sharing options...
dillon Posted August 2, 2019 Share Posted August 2, 2019 Try operating the primer index arm manually, by pushing it counter-clockwise. Does the disc rotate far enough for the detent ball to click into place? If not, then the index arm is damaged. If it does line up with manual operation, examine the black nylon cam bolted to the right side of the front part of the frame. It is possible this was damaged to a point where it no longer forces the index arm all the way over. If this appears to be the case, put a piece of cardboard behind the cam to shim it outboard, so you can load for now. Then contact us for a replacement. Be sure the axle pin that the primer disc and index arm pivot around is greased. If it's too dry, the primer index arm can fail to come back fully.

Nathanb Posted August 2, 2019 Share Posted August 2, 2019 I went through about four months of issues with priming and it was just by chance that I found it. I probably caused it too but it was completely luck that I ever noticed it. Link to comment Share on other sites More sharing options...

nightdiver Posted August 10, 2019 Share Posted August 10, 2019 I would take everything apart and clean very carefully before I start buying parts Link to comment Share on other sites More sharing options...
ExStreetWalker Posted August 10, 2019 Share Posted August 10, 2019 The primer ring can get worn to the point where the index arm can't engauge it. Just flip the ring over. Link to comment Share on other sites More sharing options...
