Breech screw trouble on a 2289g

[DavidS]

I was going to open up my main 2289g and do to it like i just did with my backup 2289g (ACP), and I found that the breech hold down screw (small allen head screw under bolt) is rounded out from to many dissassemblies, never put a philips head screw in.

Does any one have a suggestion as to what to do to get that out? Preferably in a way that it can go back in, as I do not have a replacement, nor do I have the correct tap to make one.

Thank you.

Find a T05 torx wrench, I use the small screwdriver sets from Harbor Freight and the like with the smaller interchangeable bits, it works better than the hex because it has teeth.

Thank you, I will see if I have one that size. Not going to town for a couple more weeks yet.

I have a set of easy-outs but about to order these....as seen on TV.

I recently stripped the hole in that screw and just drilled down through it with very small drill bit. Gradually moved up in size until it just popped off.. Luckily I didn't damage the tube at all. After you do get that screw out, I would HIGHLY suggest replacing that screw with one from AC Customs. I replaced all of mine with these. Good luck!

I do thank you for that.    I would rather not drill it out if avoidable.  Though I would want to find a replacement localy (either straight edge or philips).  Either way it would mean that this 2289 is stuck togather for a while.

   I removed one by tapping a tiny precision screwdriver into the hex hole till it bit into the metal.  Then squeeze the breech to the tube to loosen it while you turn the screwdriver or a torx bit if you can find one small enough.  The screw is 4-48 which is very hard to find even at hardware stores.

As stated, it's a GREAT idea to clamp down on the breech and tube to take the pressure off of the screw, this should allow you to possibly get a small torx bit or a slightly larger reverse (left hand) drill bit just barely into the hole. After you get it out, if you do not have a replacement available, you could use a dremel or something similar to cut a groove into the top of the screw to allow you to use a small flathead screwdriver to easily put it back in and remove it. I think Crosman bought those small Allen head screws from the devil...

  I forgot to mention loosen or remove the rear breech screw first.  It will cause a lot of tension on the little screw if you don't.  That makes you have to try too hard to turn the little screw and strip the head.

[DavidS]

Ok thank you both for the added info.   I will clamp down on the breach, and remove the rear screw before I give it a good try.  Then I will carefully cut a small slot to fit one of my real small precision flat head screw drivers (after and if I get the screw out).

That screw is designed to round out BEFORE the tube is trashed. Those of you who choose to replace the screw with a Phillips head run the risk of stripping the threads right out of the tube, especially if you tend to be ham fisted about it. The threads per inch on the tube is 48, so with approx. 1/16 inch tube wall thickness, you have about three threads of engagement. The screw costs about $1 while the tube costs about $12. You do the math.

Pay attention to the advice given above regarding pressure between the breech and tube while you snug the screw. And get yourself a GOOD set of hex wrenches.

I have changed out breeches and barrels multiple times and never had a problem with the breech screw. I make sure the hex wrench is snugged into the screw head and I take my time screwing it in. If it binds, I stop and back it out, and try again until it screws in. I don't reef on it. So far, so good!

Same here as far as method.  I think it rounded out while attempting to extract it (Strange in my view).

Ahh, let's not forget Mr Murphy and his infernal law! I think he must have been an airgunner, among other endeavors.

Like Van said the rear screw should be loosened first the holes in the tube will not be perfect location as the tubes are punched not machined and a slightly dull punch will not put the hole where it would be if the tube was machined . We found this out over in CAPOF we had a young lady joined who worked for Crosman and ran the punchpress putting the holes and slots in the tubes so remember little screw FIRST IN LAST OUT

Thank you all very much.  I was able to get the screw out.
