any of you modders ever put back a break barrel together only to get that ratchety feeling when you cock it, well i got that, and have no clue why it does it

i thought it was the pin holding the two part cocking arm scratching the inner side of the stock, i could see where it made contact, so i shorten the pin on each side, and sanded the inner stock, no luck, still doing it, it sounds mechanical, gun locks and fires with no issue

thoughts, experience

When you say ratchet sound is it just a single ratchet sound (click) or a couple (Cick,click,click,click) make sure the cocking arm isn't running along the spring.

I had that happen on my air hawk once. It turned out to be the cocking arm. The piece that pushes on the plunger was bent in, just enough to touch the spring and make that ratcheting noise. I took it apart and ground down the underside facing the spring, and put it back together. All fixed. Sound, s like you already tried that though Good luck,

Did you take the spring out and re-installed it?

the rifle i'm talking about is also an airhawk, i haven't touched that part of the coking arm yet, i'll take it apart and inspect the underside, might be my issue as well, i took that rifle apart several times and matched other airhawk parts to it

ace

its a few clicks, didn't count them thought

took the stock off, grinded a bit a material off the cocking arm's underside, and a bit off the upside as well, tried it, same thing, that's not the issue, the arm is in the groove of the plunger where its suppose to be, no contact with the spring at all

i tried cocking the rifle without the stock, and each time i hear and feel that click, i can see the spring jump inside the action :?:

Would it be missing a piece? Is there suppose to be a "sleeve" the fits inside the piston and over the spring? My Umerax Surge (air hawk clone I believe) has such a "sleeve" and prevents the cocking arm from touching the spring.

i'll take it apart tomorrow and inspect the inside...sigh

i'm thinking there's something funky going on with the spring guide, as for the piston side, i would think that since i cant see the inside of it from the slit, the sleeve is probably present

but the arm catch is definitely not touching the spring as it can't go lower than the piston and touch it, i would have seen that while i cocked it :x

well good to know you eliminated that part out of the way, :wink:
somethings definitely rubbing against the spring in there, you got no choice but to open that puppy up.

Post subject:  Re: ratchet feeling

went back to my shop and looked thru the bags i keep parts in when i have a rifle disassembled, the diagram of the ruger shows a washer between the spring and its guide, not sure if its the bag i used to store that particular spring, but here's what i found...

Sounds like the pipe casing is dented causing the spring to click/grind when cocking...

Post subject:  Re: ratchet feeling

i'll do a thorough inspection tomorrow and see what's what, if its really missing its washer, my bet is that when i cock it, the spring digs in the guide, that would explain why the spring jumps, but will inspect the casing pipe just in case, night
