bullbob Posted January 9, 2016 Share Posted January 9, 2016 That big box was there when I got home from work today. Within about an hour I had it unpacked and bolted down to the bench I had been prepping for it. Went together pretty smooth, strong mount, bullet tray, empty case bin, all good. But when I put in the shell plate and sprocket, it doesn't seem to rotate or index quite right. I double checked the spring and ball, and added a drop of oil, but no help. It seems to tighten up on 2 stations and loosen up on the other 2. Tight enough that I can't feel the ball drop in the detent for that station. Do I need to loosen it up more? Only other thing I did was to change from the large primer setup to the small. Any ideas? Help!!!!! Thanks bob Link to comment Share on other sites More sharing options...

I had the shell plate in upside-down. I had the Dillon video and watched it carefully while I was putting it all together, but I'm afraid the Dillon video is a bit lacking in detail.

bullbob Posted January 9, 2016 Author Share Posted January 9, 2016 Nope,I double checked that, shellplate is in with the number up. Thanks bob Link to comment Share on other sites More sharing options...
Clipper Posted January 9, 2016 Share Posted January 9, 2016 I thought the printed instructions that came with my 550B were most useful, I managed to get it going without much problem, and it illustrated how to switch from LP to SP...my first time wasn't speedy, but I did get it done, finally...

ChemistShooter Posted January 9, 2016 Share Posted January 9, 2016 Dillon customer service is great. Try a phone call. I had to call them twice. Got them on Saturday morning once. Odds are not good on Friday night but it's worth a shot.If you can attach a picture, that would be helpful. Link to comment Share on other sites More sharing options...
Erick85 Posted January 9, 2016 Share Posted January 9, 2016 (edited) Mine does that also, but only on one station/part of the rotation. I would think loosening just a tiny bit would help. On mine, there seems to be a sweet spot where loosening it a tiny bit one way causes the shell plate to rock ever so much, but the other way it wants to tighten on that one spot of the rotation.

ChemistShooter Posted January 9, 2016 Share Posted January 9, 2016 What instructions are you using? Do you have the video? IIRC, it says to put the shouldered bolt in, turn till it stops, then back off a quarter-turn, then put the set-screw in the ram. Link to comment Share on other sites More sharing options...
ChemistShooter Posted January 9, 2016 Share Posted January 9, 2016 (edited) I also had a problem with the cartridge case bin mount bumping the shell plate and stopping the rotation. The cartridge case bin mount entrance was too close to the shell plate. I fixed that by putting the empty case bin mount in-between the strong mount and the cartridge bin mount. That backed the cartridge bin mount off far enough to stop the bumping. Edited January 9, 2016 by ChemistShooter Link to comment Share on other sites More sharing options...
RonPogi Posted January 9, 2016 Share Posted January 9, 2016 The powder rod should be installed and check the primer seating cup didn't hit the shell plate while rotating. Link to comment Share on other sites More sharing options...
bullbob Posted January 9, 2016 Author Share Posted January 9, 2016 Got it. It was the loaded cartridge ejector wire, it was slightly rubbing on the indexing sprocket. I tapped it down just a hair and... nice smooth rotation. I will also keep an eye on the case bin brackets and such. Thanks for the help. bob Link to comment Share on other sites More sharing options...

texasref Posted January 9, 2016 Share Posted January 9, 2016 Tighten the shell plate down just enough to feel the index. It will tighten up at this point as you rotate the plate. Loosen a little and make sure you tighten the set screw under the shell plate holder located on the shaft. Link to comment Share on other sites More sharing options...
RudyVey Posted January 11, 2016 Share Posted January 11, 2016 On my new 550 one arm of the sprocket is slightly bend down, so it hits the ejecting wire slightly every fourth case. Not sure if I should attempt the straighten it myself, or ask Dillon for a replacement. Looks like zinc die cast, and I am not sure how well this can be straightened out.

tires2burn Posted January 20, 2016 Share Posted January 20, 2016 The wire will move up or down.

RudyVey Posted January 20, 2016 Share Posted January 20, 2016 Even with the wire in the lowest possible position, it hangs up every fourth round.... The wire will move up or down.

RudyVey Posted January 20, 2016 Share Posted January 20, 2016 Dillon answered me back, and they say to try to straighten it out, i.e. bend back. If it breaks, they will replace it. Will work on it over the coming snow storm this weekend. Link to comment Share on other sites More sharing options...

Loosen a little and make sure you tighten the set screw under the shell plate holder located on the shaft. Thats how I do it. Also if you run one case or no cases it acts funny, when full she runs smooth. Link to comment Share on other sites More sharing options...

Here is a photo of the bend arm - see the bend arm on the left side of the picture, it is standing slightly up - the sprocket is upside down, so normally, the arm is bend down and hits the ejector wire. After the photo was taken, I was able to bend the arm back and it works now flawless. Link to comment Share on other sites More sharing options...
Walnut Posted January 24, 2016 Share Posted January 24, 2016 I have bent and re-bent mine a several times. Especially when I pull the handle with it empty and not paying attention to the location of the shellplate. I have just bent it back. No issues so fare. . . . .
