Title: I messed up how do you put the plastic breech sight back on
Post by: rittah on May 06, 2011, 02:21:54 AM
Ok, I am putting the plastic breech back on (long story don't ask) but the screw isn't screwing back in. what did I break and how do I fix? Even if I go back to the steel breech the screw will not screw in.
thanks

You have to hold everything together to screw it in. If you don't have the endcap on, there is nothing ffor the screw to set into.

Hope that helps.  Want to sell your steel breech?

thanks, but going back to the steel breech. I have decided this will not beat me. so I went back to the steel, I put in the breech screw and then held the back and then put in the plug into the back of the steel breech and the screw will not screw down. Seems to hit the set screw of the back. I don't know maybe I will just leave it off lol

Are you using the OEM plastic rear sight?  If so, that sight does not fit on the Crosman steel breech.  So how are you trying to mount it?  Also, don't understand your reference to a set screw on the rear end cap.

Nope leaving the plastic sight off. it says to use the same screw though to screw into the back of the breech through that plug they gave me. If I take the breech off, I can see a set screw that holds in where you would put in a power adjuster. then there is a little gap then it hits the cocking pin. I am not removing the back cap which is 2250-004 in your pic, should I be?

Did you line up the holes?    (Not to be translated into 'how dumb are you?')....

Can you put up a pic of what you're having problems with? Your description is hard to envision (translate into: 'we don't know what the %$*& you're talking about')

Haha  :-*

no worries, I take of offense. let me figure out how to put up a pic

Ok, here is a pic. The screw just stops like it is too long. it is the original screw.

Is it hitting the hammer spring maybe?
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: rittah on May 06, 2011, 03:51:45 AM
not the spring but what appears to be a set screw at the end of that cap. I can take it apart again if that would help get a better view. If I unscrewed that cap it would probably fit but then I am afraid the cap wouldn't go on.
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 06, 2011, 03:51:54 AM
Another simple question.  What gun are you working on?  Is it a 22xx CO2 or a 1377 pumper?

That part you listed, 2250-004 - the end cap, is where the screw you are having difficulty with should screw into.  It has two threaded holes opposite each other.  Trigger frame screw goes into one side, rear breech screw into the other side.

The rear breech screw should should be about .75" if I remember correctly.

I wonder if that cap could have turned on me.
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 06, 2011, 03:54:07 AM
That screw is way too long for the steel breech. Your new steel breech should have come with a new screw for the rear.

Carl

Post by: quickster47 † on May 06, 2011, 03:55:50 AM
The rear cap is symmetrical so if it turned it shouldn't matter.  Just make sure the holes line up.

Carl
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 06, 2011, 03:57:20 AM
If it's hitting anything it would be the hammer spring and that is bad.  As I stated before, that screw is too long for where you want to use it.

Carl

Ok, so I need another screw
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: slothart on May 06, 2011, 04:02:07 AM
wow... quickfire

Are you using the screw that came with the stock plastic breech or the screw that came with your steel breech?

The screw for the steel breech is significantly shorter because it does not allow for the stock rear plastic sight.  Based on the pictures, it looks like you are using the stock screw... at least that is my guess.
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 06, 2011, 04:02:37 AM
Yes you need a replacement screw.  The one used to hold the plastic rear sight is too long and should NOT be used.  As I mentioned previously, I think that screw is .75" (3/4").

Carl
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: woody67 on May 06, 2011, 04:03:36 AM
Yes.. how long is the screw u are using and where did you get it?

Is the 'set screw' u mentioned the one that attaches the tube to the trigger frame/grip handle part?
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: rittah on May 06, 2011, 04:10:39 AM
I took off the breech, does this look normal?

ok thanks all and thanks Carl
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: slothart on May 06, 2011, 04:14:56 AM
I took a picture of the screws... the one on the left is the stock screw for the plastic breech with the rear sight.  The one on the right is the screw for the steel breech. (the yellow grid underneath the screws is made of 1 inch squares for an idea of scale/size)
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: rittah on May 06, 2011, 04:23:42 AM
wow ok, if I took my dremel could I make this screw work correctly, or is there some thing else different about it.
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 06, 2011, 04:35:01 AM
Yes you can use your Dremel to shorten the length.  Just make sure the threads on the end are clean so they thread into the end cap okay.

Don't understand why you did not get a new rear breech screw with your breech.

Carl

Make sure you dont tighten the bottom screw that holds the frame you wont be able to move the end cap to line up the holes.

Post by: NorthStaR on May 06, 2011, 02:01:54 PM
I dremeled my breech screw. Even the one supplied was too long (GMAC breec, especially with a P.A).
But you also can add a couple of washers to raise it up if you don't want to cut it (but it may interfere with your rear sight).
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: rittah on May 06, 2011, 02:33:33 PM
Crosman responded to my email this morning they are sending
Out the screw. Should get it 5 to 7 days
Now I think it was Mike that said this. What do you mean lining up the holes?
Do I need to turn that cap on the end or is is ok.
I uploaded a pic without the breech on top.
Please outline all holes I need to worry about.
Maybe I can get this working so my wife stops laughing at me lol
Title: Re: I messed up how do you put the plastic breech sight back on
Post by: quickster47 † on May 07, 2011, 01:34:47 AM
If you look at the end cap the two 8-32 tapped holes are opposite each other, essentially the hole is drilled all the way through and then tapped using an 8-32 tap.

The bottom screw comes up through the trigger frame.  It is the 8-32 x 5/16 screw used to secure the rear of the trigger frame.  When you install the rear screw of the breech make sure the back screw in the trigger frame is loose so you can wiggle the end cap to get the screw in the rear of the breech started.  Hope that makes sense.

"I think i said that already but not in so many words "  Truthfully, and I do know this will be difficult for you Mike, when you stop and think about it, was your comment really necessary?  No it wasn't. You were just trying to get a dig in on me, again.
