Fix for the snapping shellplate on a 650


Recommended Posts

Thanks Alan

Other than the ring indexer cam and tension what other ways are there to adjust the position of the shellplate? I ask because mine seems to index to far (i.e. the primer seater rod is closer to the right edge of the shellplate. If I could I would just move the cam back towards the front (is that right?) so that it wouldn't index the plate as far but I have it moved as far back as possible. All your help in this regard is very much appreciated. :bow: I'll be calling Dillon on Monday, but if you have a quick reply so's that I can load this weekend that would be great!

*if* with the shellplate set such that the ball is fully in the hole on the underside, and the primer plunger is still off alignment, there is only one option, that is get the timing/alignment tool from Dillon and re-set it. I know of no other way to fix that problem. On my 650, the enitre head needed to be turned to allow the powder funnel to align with the case, but the primer to shellplate was perfect. And obviously, the bearing made all the difference in keeping the powder in the cases :)...

Thanks Alan it's defintley something other than the shellplate now that I have the bearing and the xylon coated shellplate installed. At times it seems to be the primer ram catches on something and other times maybe its just me. As a white guy I have little rhythm so I'll have to work on getting a smooth cadence going with less jerk in it. Which reminds me of a saying "Slow is smooth and smooth is fast" or something like that but in all likelyhood it probably just means replacing the "jerk" pulling the handle. :roflol: Since I'm sorta new at this I'm going back through all my brass and checking for a military crimp and other problems with the primer pocket, and my other handloading methods etc. etc.

Specifically watch for S&B and Fed NT, S&B have undersided pockets and I have to run them thru my 600 swagger if I decide to use them. And Fed NT have crimped pockets and have to have the same... I have so few of both, that I usually just throw them aside until I get around to messing with them.

Ypu might try loosening the two bolts that hold the primer assy to the press. There might be a little play there, enough to center the primer seating tool. If not, give the folks at Dillon a call, they have been very helpful in resolving the few problems I've had w/my 650.

Now that I put more than 1000 rounds with this new upgrade, I think it's worthless. Sure it works perfectly when the shellplate screw is tight but it will get loose after 100 rounds making the shellplate snap again. Is there a cure for this?

You could try a dab of BLUE LocTite on the screws and wait 24hrs for it to cure properly.

Isn't the shell plate setscrew suppose to keep the shellplate screw from loosening up?

first, the large shellplate bolt is secured with a brass tipped set screw, if you haven't tightened that, then doesn't matter what you do, your shell plate will get floppy and sling powder.

Second, I thot I had mentioned above that on first install, you'll have to re-tighten the shellplate bolt after 100 or so rounds, this is due to the fact that the grease that in the bearings will squeeze out from the initial install pressures and you'll have to tweak the tightness of the shellplate bolt to accomodate that.

I've loaded over 1000 with mine and and it's just as good now as it was after my first re-adjustment.

+1 on that the setscrew.... when i originally had problems it was because I had forgotten to tighten said setscrew.......

Guys, I know about the shellplate brass tip setscrew. The shellplate bolt keep loosening up no matter how tight I torque the setscrew. This setscrew is still jammed up pretty good but it does not prevent the shellplate bolt from getting loose. Should I order these 2 parts from Dillon?!? halp!!

this sounds odd to me and more like the shellplate bolt was incorrectly tensioned to begin with because from my experience if the setscrew is loose or did loosen, then the shellplate bolt would gradually tighten down on the shellplate with each turn of the handle until the shellplate jams, and the ring indexer fails to index and you risk breaking the ring indexer.....I know this because i forgot my setscrew....loaded a few hundred and yep...jammed the shellplate and broke a ring indexer.

If the setscrew is tight against the shellplate bolt I can't imagine it loosening (if it is tight)

Is the shellplate bolt shaft damaged? is the tip of the setscrew looking worn and damaged? If they are then its probably worth replacing them....a quick look should tell you.

I should also add.....smooth technique in operating the machine is half the battle...specially with a 9mm or similar.....the shellplate fix for me only covers part of the problem...if you knock the machine, run it inconsistently or if your primer seater is out alignment even it can spring up and knock the shell against the shellplate and rattle everything....

My advice is check the parts...if worn out replace, then carefully run through slowly one station at a time and examine everything....its a fiddly pain in the ### but once its right its worth it.

I just received the bearing and washers the other day. Installed it in a couple of minutes and WOW, what a difference. This Forum is FULL of endless pieces of information. This totally eliminated the powder popping out of the case when indexing to the next stage.

THANKS AGAIN!

Sorry about resurrecting this thread.

I just now got around to trying this mod. What I discovered was that when I tightened the center bolt down enough to prevent the shell plate from snapping (with the bearing and washers installed), there was noticeable friction and a grinding feeling between the shellplate and the ball bearing. I know it was the ball bearing and not something else because I removed the ball bearing and the friction/grinding feeling went away.

And if I backed off on the center bolt tightness until the friction/grinding feeling went away, then the shell plate started to snap (even with the bearing and washers installed).

So, to solve both problems I decided to also cut one coil off the spring under the ball bearing. This in conjunction with the bearing and washers is giving me a nice, low riding, shell plate that doesn't snap. Not only is this going to eliminate the snap, but I think my OAL variances (from case to case) will go away as well.

Thanks for the info.

Used side cutters on my spring, too. Cut it like butter...

Ordered up two sets - since they're cheap and I have to pay ground shipping, might as well have a spare on hand, right? :) We'll see if this can stop any powder flinging using N105 in SuperComp. That'll be a definitive test, right there, my friends!

Also, ordered these... 97431A310 - 5/16" E-clip for the decapping pin on a Dillon sizer die. My .38 Super die keeps breaking them, and ordering from Dillon, while free, just gets to be a bit much. At Home Depot, these things are something like $.20/ea. At McMasters, $5 for 100!

David I just used 1 washer on top to avoid the ejector spring issue. The shell plate is smooth and flat what the heck does the bottom washer do, jacks your ejector spring up. It works for Major 9 and the cases are plenty too full, and did I mention Bullet Feeder.

Alan this is a wonderfully elegant solution!

My girll bought me a 650 for Christmas and after I got it set up I discovered this issue. "Where to turn?", I asked my self and the answer was clear, Brian's joint!

I ordered my parts from Granger:

Berring 4XFN2 http://www.grainger.com/Grainger/INA-Thrust-Bearing-4XFN2

Washer 4XFP9 http://www.grainger.com/Grainger/INA-Thrust-Washer-4XFP9?BaseItem=4XFN2

Cut a coil off the detent ball spring and bingo, smooth as silk.

Many thanks!

The shell plate on my new 650 was snapping and spilling powder. Riding the shell plate with my finger solved the problem, but it slowed me down and increased hand fatique. I snipped the spring while the bearings and washers were in the mail, which eliminated most of the snapping of the shell plate. After later installing the bearing and washers and loading 500 rounds of 9mm, there was no spillage of powder on the shell plate of my 650. Great mod, AA.
