Smitty79 Posted April 29, 2017 Share Posted April 29, 2017 I have a 550B with a case feeder. When I cycle the handle, the system hangs up as the primer cup reaches the hole. I have the slide bar adjustment screw (14037) set up so that the Primer Slide Return Spring Post just touches it with the primer cup centered in the hole. What I see happening is that, as I lift the handle, the Primer Slide Return Spring Post touches the screw (When the handle is about 5 degrees from vertical) and then backs away just a little, maybe 10 to 20 mils. The primer cup looks like it's hanging up on edge of the hole in the shell plate on the edge towards the primer slide. If I push the slide in a little, or wiggle the case feeder a little, the primer cup moves into the hole. Any ideas? I can make it work. But I hate having a machine that doesn't work right.

Sorry but that's what I did after dicking with the 550 priming system long enough. But if you insist on keeping it, Things I would try first are spinning the primer cup to see if it lines up better, loosen the entire punch and turning it a little, tear the primer system all the way down and clean it , call Dillon.

I just bought a 650 from one of the local Masters who bought a 1050. I'd like to use the 650 for 9 and the 550 for other stuff. Link to comment Share on other sites More sharing options...

benos Posted May 1, 2017 Share Posted May 1, 2017 550 Priming Assembly Adjustment Notes: Thoroughly polish frame, wherever priming slide touches it, with green Scotch Brite. (Approx. every 3000 rounds) Wipe off Primer Slide with solvent or alcohol. Leave it all dry. At rest primer slide adjustment: Set so that one primer, dropped down the tube, goes all the way into the Primer Seating Cup, 10 times in a row. Angle of Primer Slide Operating Rod (13869) - Release rod from rollers and swivel it 180º so it's pointing straight up - it should be parallel with the Primer Housing Shield, or maybe outward "a little"; it should not be "inward" at all. Be sure both screws (14530) that tighten Roller Bracket Shell Platform (14280) from bottom (to the Shellplate Platform) are tight! Make sure Priming Seating Punch Assembly is fully bottomed out before tightening screw (13996): Measured from bottom of Primer Slide (13920) to top of seated Primer Seating Cup (13284/5), dimension should be between 1.215 - 1.220 inches. Be sure Priming Operating Rod Bracket (13887) is adjusted so it's within a few thousands of an inch from the top of frame/Toplhead. Be sure the plastic tips of all your Primer Pickup Tubes and the plastic tip on the bottom of the Priming Magazine are seated fully against the tubes. Grease the short end of the op-rod where it inserts into the bracket clamped around the primer shield. Link to comment Share on other sites More sharing options...
