I have the Lee 50th Anniversary reloading kit and love it. However the Large primer arm often falls out of the press and onto the concrete floor and so I have bent the large primer guide, thus it does not accept the primers and makes it dangerous to try and seat the primer in the casing. So I looked on the Lee website and found you can buy new ones. At 50 cents a piece I thought I'd splurge and buy 4! So I got them home and tried to change one. The piston on the arm that has a spring and the guide on it seems like its actually PART of the arm. I got a plyers on that little piston thinking it was either screwed into the arm or pressure fitted, thus thinking I could unscrew it or loosen it. Not a chance! Anybody have an idea how to change those little guides? I mean you can buy the parts you should be able to change them, right? Perhaps one needs to put some heat to it or something. Anyways, if anyone knows a) what I'm talking about and b) what to do about it. Please let me know!

Thanks!

post some pictures i say!


if your talking about the lee primer arm, it's (from lee's parts website) all one piece. Link - Click here

but if your talking about the ram prime setup, Link - Click here then it's friction fit. i get a flat head screw driver and lightly pry the 2 arms/lobes (can't think of a proper name at the moment) then remove the priming pin.

definitely sounds like you ordered the wrong part.
 
Thanks guys. Yes the part I'm talking about is the first part you linked to "Spawn-Inc" So the part I bought would only work on the second picture you linked to. So I do need the whole arm. Well that clears it up--THANKS

To prevent it happening again once you get it all sorted, take some emory cloth to the centre of your shellholders.
A couple of mine had very slight machining marks in the hole, and it was just enough to catch every once in a while.
I'd polished up the primer arm so it shone, a light film of oil, everything as smooth as glass. Good to go.
Prime two cases, and the #$%# arm would go flying!
Took a while to figure out it was the shellholder, and 3 minutes later it was fixed for good.
 
same happened to me too, but it didn't break. Getting sick of that lee crap jumping out of the press. kmon, I mean, they could have added a locking pin or something.
 
Hey major news bulletin:

GEOF here again. I found out that I DID NOT have the wrong part and that you can replace the primer guide on these arms!!!! It turns out to be real easy. When I posted this at first I also sent an e-mail to Lee and they just got back to me today. I tried to upload some pictures, but the only option appears to be from a website. I'll have to look at some stickies and if I can do it, I'll send them if I can get this figured out. But the steps are as follows:

1. Take the primer arm to a vice
2. Clamp the arm in so that the top of the arm is level with the top of the vice and just the pin, spring and primer guide are sticking up.
3. Take a hammer and put the claw of the hammer on the pin, under the the little primer guide.
4. Take another hammer and tap on the handle of the first hammer. The pin is just pressure fitted into the arm and with this amount of leverage comes out quite easily.
5. Slide the spring off the bottom of the pin, slide the old primer guide off
6. Slide the new 50 cent primer guide onto the pin and replace the spring.
7. Put the pin back in the hole on the arm.
8. Take the arm out of the vice and then put it back into the vice, this time using the jaws of the vice to squeeze the pin back into the hole.
9. When the vice stops squeezing the pin easily, the pin is seated properly back into the arm. One minute job that will save you about six bucks (50 cents for the guide vs 7 bucks for the complete assembly)

Hope that all makes sense, but Like I say, I'll try to add pictures.

Here is a link to the pictures, that hopefully will clear up things:

1. Putting the primer arm into the vice: http://i1336.photobucket.com/albums/o644/geofc/P25-03-13_1653_zps182dca05.jpg

2. The arm in the vice: http://i1336.photobucket.com/albums/o644/geofc/P25-03-13_1654_zps0c263592.jpg

3. Removing the pin assembly by using a hammer claw and then tapping on the handle of that hammer, with another hammer: http://i1336.photobucket.com/albums/o644/geofc/P25-03-13_16541_zps069cca0c.jpg

4. The Removed pin assembly: http://i1336.photobucket.com/albums/o644/geofc/P25-03-13_1656_zps7cfa4b89.jpg

5. The you take off the spring, take off the old primer guide put the new one on and reassemble using the vice: http://i1336.photobucket.com/albums/o644/geofc/P25-03-13_1658_zps03e91f48.jpg

Hopefully that is helpful!
