So I picked up this cq awhile back cleaned it up and realized the bb inside the cap was misshapen and leak air back out at me. Is there a good way to repair this? I was thinking about pulling back the tabs a bit pulling the old one out and replacing it with something similar and beating the tabs back. Has anyone done this before? I figured I would check first before I don’t ruin something. Thanks in advance. 5E93107B-E36E-45F1-A159-66731A91D051.jpeg

If the check back is misshapen I'm not sure you could hurt it any more... I'd try it ðŸ‘

id try some lye and then a citric soak first , lye to remove any organic material , citric to soften the rust on the ball , they poke at it with a shishkabob stick removing the softened rust .... or try another cap .

Well and pulled the tabs back a bit and got it out but this is a pretty small bb. If you look close you can see the flat spot and a little raised area off the flat which is what is causing this. F2AA4DD3-0BAD-43E8-8BED-123A9EA130DD.jpeg E4D95E66-5705-466F-8FF1-0A23E2FCAF8A.jpeg

Well I checked another cap to see if the bb inside would take a magnet and it didn’t. The bb In the one I’m working on does not take a magnet either. So I’m assuming these are lead bbs to begin with. So I pulled a piece of shot out of a old Wax paper shotgun shell That had a similar size and Installed it. But it only slowed the leak a bit. Any ideas?

Yeah I might get some of these ball bearings Steve above mentioned in a old post and try but it seems my eyes don’t want to work well for me today and it’s so damn hot out

Get a stainless ball bearing and you're good for life. McMaster Carr has every size you could imagine, but you might need to buy a hundred.

I'd pull that lead shot out and try to clean the seat in the cap. I've had good luck with a toothpick wrapped in 4-0 steel wool for cleaning seats.
It's priceless until someone puts a price on it.

BTW: 0.125" is 1/8"--a very common size. You should be able to find a hard-chrome bearing at the hardware store.

They are not supposed to provide a perfect seal, that is why you screw it down when done pumping. How bad does it leak?

Enough that it would shoot a lot of vapor out if I wanted to pump up while running. My other ones shoot out when I loosen but seal almost immediately. I’m going to order some tight tolerance 1/8 stainless bearings and try polishing the seat well and I’ll take it from there.

You could regrind the seat lite a mini-valve grinding.  Just need a ball glued on the end of some sort of stem and a bit of compound.  Might be easier to just round the end of the correct diameter rod and use that to finish the seat.  

I have had a couple, notably Leacock, caps with new balls (and in their case, seals) that didn't seem to seal well until I had some pressure on them.

I was thinking yesterday that if everything else fails you could always drill and tap it for a valve stem.

The ball can be driven out with a small pin punch without prying the tabs back. The tabs will get out of the way. Dress the seat with a drill bit (smaller than the ball) by hand IF it needs it. Put in a new steel ball and tap back in with the punch. Tap the ball lightly to seat the ball. It'll work. Ya might have to tap the tabs lightly as well to keep the ball retained. As someone mentioned, it doesn't have to seal completely, just slow the air leaking out. The screw's taper and seat seals it.

Many of my old plugs don't seal, I have to hold the pump shaft down while I screw the top part down.  Vinegar and lye were no good.
