Author Topic: Worn Hinge pin. (Read 567 times)

#1 How are these removed? #2 Can I order a new one? #3 Can I just pop it out and turn it 180 degrees and put it back? I tried it on my NEF shotgun receiver and it locks up real nice and tight, so I am pretty sure most of the wear is on the pin, (I can SEE it) and not so much on the lug.

Robert, from a previous post, which I can't find, the pivot pin is machine pressed in and I don't think it can be removed, IIRC. It would be easier to build the barrel pivot up with either weld or as I did on the .270 UltraComp which can be found in the FAQ sticky. As I remember it, the pivot pin is much harder than the barrel pivot, so would not likely be the worn part. The barrel pivot is fairly soft and can easily be filed, in fact, in essence, that's how they are fitted at the factory and how I fit barrels that are too tight, which has been the case more often than not.

Thanks again Tim

Robert: The pin can be removed, but be prepared to use some force. I started mine on an arbor press, then finished with a brass punch and a hammer. The pin is hardened, so it wearing is remote. If your barrel needs tightened try shim stock first as a starting point, then go from there. Good Luck: :-) <>< Duce:

Maybe his pin didn't get hardened or maybe not as much as it should have been.

Or, perhaps what you're seeing is the finish worn off so that it appears to be worn when in fact it is not.

What are the first letters of you rifle's serial number? Maybe the factory is the way to go. I'm wondering...I think I remember reading that gun parts corp. or someone can supply a new pin. If you could get a caliper on it you could measure the diameter at different points; if you remove it this could then be done. You could roll it on a flat surface to see if it's bent or out of round.

Just a few thoughts.

Robert: I was rushed when I replied yesterday and didn't completely answer your question. The pin I removed was on a 22/250 and yes I turn it 180 and reinstalled it. What I was trying to insure against was wear and with the pressure this cartridge was maybe the pin was bent every so slightly. I couldn't see or measure any deviation, but it did lock up tighter with the change. Remember to line the spline up when you reset your pin.

Thanks Guys. I will probably just live with it till I send it in for a 7.62x39 barrel this summer....then I will include the replacement with the barrel fitting.
Cheater...the serial starts with NN
