S&G 831 B Disconnected Shackle

[Darski]

Does anyone know what it takes to keep the shackle from falling out?
It sounds like removing the shackle on this model is supposed to be difficult but I haven't found any instructions so I can't reverse the process.
Thanks in advance.

See on the bottom of the shackle there is a cutout? There should be a roll pin in there but yours has been sheared off which allows the shackle to come out.

Remove the old one and get a replacement. To install it take out the locking bar and cylinder and put the shackle in. Turn it to the side and you will be able to see the hole in the hold in the lock. Put the pin in and make sure it is in tight.

Thanks for the response. I'm afraid that I didn't take a very good photo of the bottom of the shackle. Unless I misunderstand you, there's a pin present in the cutout at the bottom of the shackle. It's pretty rusty but it's intact.

I am not an expert here but I seem to recall there being a sequence of key and shackle turn necessary to remove the Shackle..

1- Something is misaligned/missing
2- The part that catches the pin is broken not allowing the shackle to stay retained.

Did you remove the shackle or has it always been that way since you came into possession of the lock. ??

Only thing I can find is this .. and I am not even sure it is for a 831B

The pin should be sticking out. It would need to be broken or drilled off to remove the shackle.

The control key allows removing the slider that accesses the cam and core, but does not allow for removal of the shackle.

So the pin is sheared off ??

That is what it looks like to me. Would have to dig out an 831 to take pics, but that would not be easy now.

The information sheet (which is better than I've seen before) looks pretty similar but it also looks like there's a couple differences from this lock model. The lock has been this way since I bought it (photos didn't reveal the problem). The seller found it and doesn't know much about locks or this one's history. He was apparently unaware that the disconnected shackle was unusual.

The lock has two keys, the operator's key and the control key. I'd understand if the shackle fell out after using the control key and the gate (I think that's what it's called) falls out but the shackle falls out no matter which key is used or what position the gate is in.

Do you mean that the pin should be protruding from the side of the shackle?

I've heard that the shackles should be essentially unremovable but it seems like if they got the shackle stay connected before, it should be repeatable somehow.

Two more observations/thoughts:

When the shackle is pulled out far enough to swing open, the bottom of it can barely be seen through the gate hole. (That's the glint of silver at the top and back of the opening in photo #1.) I'm having a hard time imagining how the shackle can be retained when so high in the housing. It occurred to me that maybe the shackle is from a different lock. Then again, it might be my lack of imagination.



Secondly, there's a rectangular/stake-shaped pin secured in the gate (photo included). As-is, the pin doesn't move. One end of it tapers to a point (I had a hard time photographing this) it seems like this pin should be doing something but just sits there. I can't physically move it. I've considered pulling the smaller set-pin (almost looks like an allen set-screw), inserting a spring and reversing the rectangular pin but, as I observed above, I don't see how that can do much if the bottom of the shackle rides as high as it does before allowing itself to be rotated open.



Thanks for your responses.

Looking at the picture of your disassembly plate, it looks like the center part was put in backwards and there is a missing spring. Remove the pin , slide that center part out, flip it around, then reinstall the pin with a spring behind it.

Thanks. I just tried that. I also tried the now spring-loaded bar in two positions 180 degrees from each other.

It didn't seem to do much more than pop out the disassembly plate better than without the spring-loading.

[Darski]

The reassembled disassembly plate:



Despite the fix, I think the shackle is too short to be affected by the spring-loaded pin because for the shackle to turn, the very bottom of it is beyond the reach of the spring-loaded pin.



Thanks for all the input.

Looks like the lock has suffered some abuse and will need some new parts.

I might have a shackle and padlock body for you. let me check my parts bin tonight.
