Pop rivet stem removal? Answered


I need to use the pop riveter today, but there is a leftover 'stem' thingy stuck in it.
I've removed the nozzle (?) and squeezed the handle a few times. but it's still stuck. I've tried pulling on it with pliers with no success.

Take the jaws out (you'll have to remove the keeper and the pin in the frame) and tap the end of the stem out from the back side. Then clean the grip ridges inside the jaws and re-assemble.

Keeper pin?

I know this is an old thread, but for anyone in the same situation, to me it looks like the stem is stuck because there isn't a nozzle inserted. The threaded part of each nozzle pushes against the internal grippers forcing them apart.

Thank you, KevinR55! I can't remember now if I didn't use a nozzle or if I had already removed it when I took the picture. In the future I will definitely use a nozzle as your post suggests.

an even easier way to remove a pot rivet stem! Turn the device upside down (like as shown in the photo here) and tap it hard on a hard surface whist the handles are squeezed tight - the stem will just drop out!

Thanks! That is one thing I didn't try last year. The stem wouldn't release from the jaws until the jaws were removed, so It might not have worked, but it will be the first thing I'll try the next time it jams.

OK, we found the keeper pin. Took the thing all apart. Got the stem out.
Now the big question is, how do we put it back together?

What we've been doing is
Pull back the spring,
put in the handle,
wiggle space to drop down the puller upper cylinder.. with the flat sides where they belong
try put in the keeper pin,
get it in... and the whole thing is jammed.

So we've been at this for about an hour now..... there's gotta be a better way...HELP?

I've never disassembled one, so I'm afraid I can't tell you how to re-assemble it. The most I've ever had to do is remove the ferrule. The comment on spreading the handles a bit more is because that has also solved the problem for me in the past.

Hey, I appreciate all the help and ideas I can get... especially today when many people have other demands on their time. I'll add your ideas to my bag of tricks should there be jams in the future. Thanks!

A little more egg nog and you would have tried with the handle in right side up so your main problem was not enough nog!

Thanks to you all, and a holiday laugh .... the problem with re-assembly was trying to put the handle in upside down. Sigh. Pass the egg-nog :)

In my experience, using the pliers to wiggle/twist the stem usually gets the jaws to release. You may actually need to push inward.

Which is what I said, and then the OP decided to strip the thing to pieces.

Have you tried opening the handle a bit further. I've found that in some cases, it isn't reaching the release stage until I force it a bit more open.

Also, have you tried removing the ferel (sp?) ? Sometimes the shafts get a bit bent or have a surface deformity that can cause them to get stuck. As a last ditch method, I usually just unscrew the ferel (sp) and put it in a vice so I can pull or push the shaft out..

For what it's worth: "ferrule". The screw-in nozzle thingy which adapts the riviter for different-sized rivets. (See the three screwed into the handle in the photo above; that's a standard way of storing them until needed.)

Thanks. I don't usually, and I know better, but I totally blanked on that word. Too many years lving in Cleveland, where we say Fair'l instead of Fair-Yule. First stages of that forgetting disease I suppose ;-)

I unscrewed the top and got a spring and something that fits in the bottom of the spring.The jaws and stem are still in there.

I can't pull the handles any more open. Is the ferel what holds it? There's something in the top that looks like it would take a BIG flat screwdriver.

PUSH it with another rivet, from the front.

It wouldn't accept another rivet stem because the old stem was in the way.

Tap it back in. You'll release the jaws that way.

Oh! That's how we got the jaws out of the cylinder that goes up and down... and at that point , of course, the stem fell out too.
