ams30gts Posted January 28, 2015 Share Posted January 28, 2015 Not sure what is going on here. The index arm sometimes gets stuck causing some mishaps. Just not sure what it can be. I take out the arm and clean it up and put it back in. Sometimes it makes it a few hundred to 1000 or sometimes it just goes back to doing it. Sometimes it loosens itself up and indexes correctly, but sometimes it just stays stuck. Dillon Super 1050 sticky index arm - YouTube Anyone know what causes this or has a fix?

mcracco Posted January 28, 2015 Share Posted January 28, 2015 Have you inspected the holes in the shellplate and tab that engages to be sure everything is clean and burr free? Could also be the return spring is fatigued and not applying enough pressure.I have replaced several. Link to comment Share on other sites More sharing options...
blueeyedme Posted January 28, 2015 Share Posted January 28, 2015 Could also be the return spring is fatigued and not applying enough pressure.I have replaced several. Thats what I would replace first. Every 1050 owner should keep a few of these on hand. Link to comment Share on other sites More sharing options...
gigs Posted January 28, 2015 Share Posted January 28, 2015 There is one other thing it could be, it's possible to install the return spring upside down and it's under way less tension if you do that. But assuming that's right, it's probably that the spring is getting weak and needs to be replaced like others said, if there's not anything binding up the free movement of the index pawl (tip).

Brassaholic13 Posted January 28, 2015 Share Posted January 28, 2015 Is there a washer between the spring and the press casting? Looks like it to me. I've also personally screwed up the assembly on the bolt and put the spring in a bind which causes exactly what you're seeing. If there's a washer, remove it.

Will definitely check that. Pretty sure it is in correctly though. Is there a washer between the spring and the press casting? Looks like it to me.

Brassaholic13 Posted January 28, 2015 Share Posted January 28, 2015 I've got near 500k rounds on my spring now, and it's still going strong. I'm assuming you've lubed the bolt well with a high quality grease? Link to comment Share on other sites More sharing options...

Do you grease the roller too? or just the bolt the roller goes on? Link to comment Share on other sites More sharing options...

gigs Posted January 30, 2015 Share Posted January 30, 2015 If you grease under the shell plate it just turns into hard stuck-on brown gunk anyway. The most I grease the shell plate top/bottom is a light coat and then wipe as much as I can off with a paper towel. Seems to leave a microscopic layer.
