How to take apart Hammerlock link

[JB4310]

Does any one know how to take these apart, I have the 3/8 size which has split spring sleeve, which is obvious, with a little force the pin will push out.

This older 1/2" one has a solid sleeve in the middle and I can't seem to be able to push the pin out, these are pretty expensive in grade 80 or 100 which I think the yellow one is, I would like to reuse it if possible.

Thanks, JB.

Press, vise/hammer. That's all I got.

I dont know if they come apart. I spent a half a day trying to get one apart and never did. I even tried putting it in the press and it wouldn't move.

You could cut away the pin with a hand held grinder with the slim discs and replace the pin with a graded bolt and lock nut.

I'd get the highest grade available if the application is a critical one.

Perhaps some heat and a press. Are the outside pin ends peened over a little from use and could the sleeve be rusted on.

No, the pin moves freely about 1/8" back and forth. there is another smaller sleeve/retainer between the outer sleeve and the pin, everything moves around freely.

Tried pushing the pin out in a med size vise and broke the vise, didn't have enough thread in the vise and broke a couple threads off the end of casting the screw threads into. vise is OK now after some mods.
I do have a monster vise I can try, but I think there must be a trick, found some info on these things with Google search but nothing describing dis-assembly.

I don't think they are supposed to come apart.

Try calling a crane rental yard and see were the get there rigging from, and call them. Or look for a rigging supply company

Are there any hidden "C-Clips" ?

Found another link that leads me to believe the only way to disassemble it is to break the "stud tube" and replace it with the new "split retainer"
