View Full Version : Help...Stuck breech door screw


sleepy

My gun hasn't even seen the field. One of the 2 allen screws that hold the breech door pins is stuck like hell. I already broke the allen wrench that came with the gun. It's so stuck that my other allen wrench is now twisted. I tried applying heat, but didn't work. According to Fixmyangel, threadlock is not applied to those screws. The front screw came out, but it was like a war. The back one, however, won't budge.
Any input????....PLEEEEEEEEEEAAAAAAAASSSSSEEEE.

Why would you ever want to remove those screws? Do you realize what a pain in the butt it is to realign the breech so the bolt won't stick?

Anyway, since you've already removed the front screw you've realized the stock allen keys are too weak for those screws--you're better off going to Home Depot or Lowe's and getting yourself a good set of metric allen keys that won't twist/bend/snap easily as pressure is applied. There really is no other magic way to mess with those screws. Also, have you tried any WD40 or similar products? Be very careful when using anything like that to clean it all out of the gun before shooting it though.

I took it out because the door moves back and forth. I actually tried to tighten the back but it wouldn't budge. I took out the front one so that I can figure out what the threads look like to make sure I don't screw up the back. I haven't tried wd40. wil do that later. I was using a quality allen wrench. Its really stuck in there. By the way. does anybody know the size of the allen wrench. it may not be metric. It's something between 1.5-2mm.

It is supposed to move a little.

Not sure of the metric size, but SAE it's a 1/16. Fits a bit loose, but it does work.

Just to clarify, the door moves back and forth on the pins, not when its closed. When you open the door all the way, the door slides up and down the pins. At times, making it difficult for the door to close.
I don't think that this is normal.

Yeah, but at most all you'd want to do is tighten the screws a tiny bit from both sides just to eliminate the wobbling while at the same time keeping the bolt pin properly aligned with the ram. Completely removing the grub screws creates a huge headache. Like Matt said there is supposed to be a little bit of play so the door moves easily, but not too much like you said--it seems as though the front edge of the rotobreech was hitting the back of the feedneck or the back edge was hitting the solenoid housing, am I correct? In that case a slight tightening is all that's needed.

you're right, the rear of the breech is hitting the solenoid housing. I tried tightening it, but, like i said, it's stuck. i removed the fron screw to try to figure out why the back is so difficult to remove.

Gotcha. Well, now that the front screw is out see if you can't move that breech pin a bit forward either with your bare hand or (CAREFULLY) with a pliers or vice grips. You actually shouldn't be getting any resistance at all now--but try turning the rear screw counter-clockwise and see if it budges at all, then turn it back clockwise to tighten. Since it's brand new it could be a small piece of metal or other manufacturing material stuck in there.

I mis-read your email, I thought you were asking about a stuck frame screw for some reason. The breech pivot pin retaining screws are loctited in. If they are not moving at all then the marker should be stripped and then the screws heated and with a good allen should come right out. Also, you do not want to over tighten the breech. a majority of the bolt stick issues we receive are due to the over tightening of the breech.

Oh, there's still hope!!!! Last thing I wanted was to have the threads milled down and stick a plug in there. How would you recommend heating it? I placed a soldering iron directly on the screw and it didn't work. The screw isn't stripped yet, but it's starting to get there, and I'm kinda afraid of putting a flame next to this gun. Hey Bob, how much would you charge to do it? I don't want to do any permanent damage. PM me please.

WDP, please no more loctite. Please use silicone instead!

Try a hair blower... that's usually enough to loosen up any Loctite.

and if the blower doesn't work? what should I do next?
By the way, i grew some balls and took the gun completely apart.

LoL... it's really a simple gun to take apart and reassemble... much simpler than an Ego or DM in my opinion. Just keep the blower on it for a good while on its highest setting, it almost always works. Then, while still warm (now's a good time to use some work gloves) give the allen key a try. Or, if you can, try the allen key while someone else holds the blower.

I've taken my A4 apart all the time. But this is the A1 and the manual is kinda confuzing. Besides, did I mention I just got this thing? It hasn't even seen the field. Anyways I haven't done the blower yet. I'll do it tomorrow. But does anyone know if a blow torch is safe to use without ruining the anodizing? And is anyone familiar with bees wax and their effect with loctite? Supposedly it kills loctite.

I wouldn't imagine a blow torch being a good thing to use. As for the beeswax, no idea bro.

How long did you apply the soldering iron for? It will take a while for the whole screw to heat up and losen the loctite. Also you could try acetone. Put a few drops on top of the screw and it should eat away the loctite.

5 minute or so

No luck with the acetone. no luck with the hair dryer either. Anyone have more ideas?

Just send it to Bob and sit back, relax, and await its return.

best advise i've heard all day.

Ok, I officially give up.

Bob, will send her to you first thing next week. I would do it now, but I shall play this weekend.
