Problem: Replace Carrier Latch Left hand M2

[billybobtuff]

So, I can see how everybody says, "Replace the carrier latch" as if it were simple. It would be on a righty. Unfortunately on a lefty there is no apparent way to approach the pin with a punch. Righty's have that ejection port providing easy access to drive the carrier latch pin down (or up, take yer pick). Not so on the lefty. Any of you got an idea?

Everybody stumped??

Not having a lefty you will have to take it with a grain of salt but in the parts manual it looks as though there is a retaining spring at the bottom of the pin holding the carrier latch pin.

Once that was out of the way if I had the choice I would drive the pin up into the ejection port if that was possible.

Pictures would help if you could post them.

Problem is, the ejection port opening is on the opposite side of the receiver from the carrier latch. In other words, the lefty isn't a mirror of the righty. I've got no place to drive the pin up, and cant get at it from above to drive it down. I will play with the photo angle, but I'm on the road, and limited to a blackberry phone cam. I've got the M2 with me though, along with some other trade goods.
I do (very much) appreciate the thought you've got in my problem.

I've tried Google search. No luck. Have you shown a light with a magnifier to see if that pin has any sort of threaded retrieval hole on the visible side? I'm trying to envision what might exist from an engineering perspective that would address the removal requirement. Also, is it possible that it can be walked out with inertia, by striking with a plastic mallet on the side you want it to come towards, while all spring tension is held neutral, and any encumberances removed? <(this obviously will only work if it is drop in, as opposed to press fit)
Just a few thoughts. Theres a pin like that in the Ruger MKiii's that can only be removed with inertia.

The carrier latch pin is a roll pin (0.10), probably 0.75 inch long. Inertia isn't going to move it. It is going to need some persuasion. Thanks.

Begads!!! A roll pin in a BLIND hole ???!!! What was Benelli thinking ?

Have you tried speaking with a tech at Benelli USA ??? Not a fun prospect I know, but I have called them a time or two, and they are accessible. Hopefully they won't mention drills, EDM burns, or easy-out extractors though.

Bleh, I thought for sure that there would be a small hole on the back of the receiver to push the pin up or getting the retaining spring off would let the pin "fall out".

I'm with cleefurd, probably time to call benelli CS and get what the theory is anyway.

Here is a clip. I cannot see where there is anything but friction holding that roll pin in. No retaining gadget. Imagine the ejection port being on the other side, with everything else being the same and you can quickly see that part #67 presents a problem to get out, eg. no hole in the port opening.
CS has been helpful in helping me get the parts. I got them the second try. But I can see that they wouldn't have been conversant in my problem.
To be fair, Cleefurd, it really isn't a blind hole. I can drive the pin maybe 3/16" up into the groove in which the bolt ear rides. Get my handy little dremel out and cut it off, drive it again, cut, etc; until I finally wear it out. Don't want to do that. I fear I'll be forced into 1) dremel tool escapade, 2) send it to Benelli, or 3) trade it for some other sap to deal with. No good options.
I'm thinking about starting another thread with my favorite theory for the cause of this malfunction. It seems it happens just enough to others that the post might be useful, and maybe someone at Benelli might. . . . WELL IT COULD HAPPEN!

Here is what I got out of the parts manual and it shows a retaining spring (#155E) so I thought that might go a bit to help you out but if it isnt there then you might be up a very brown creek as it were...
