How to remove / replace Snap On drawer slides? Tabs go UP & DOWN

[Mohawk Dave]

read through threads, did not see this inconvenience.

Replacing slides on my KRA4107.

Existing slides have a tab going upward into wall of box, so pulling up or hitting with deadblow will not work. I learned the hard way on the first one as you can see... I bent the metal of the inner wall a little.

Do I need to cut or drill those out? They overlap with the main tabs, so I can't jiggle and wiggle.

In one pic you can see it through the slide that is still on there.

The replacements do not have them btw.

What to do?

Those tabs are called bayonets for your future reference. The slides are "bayonet mount" slides. The bayonets point down when mounting to the inner wall, and point up when mounting to the drawer. On some boxes, one bayonet will points towards the rear on the rear of the slide, and then the other will point down on the front of the slide. Those are the bayonets that attach to the inner wall.

Here's a tip:

After you remove the drawer from the slides, extend the slides all the way out and give each one a little twist with with your hand, this will help get them unhooked from the inner wall.

Correct. But I've never had to deal with that extra tab that goes opposite the bayonets. And twisting will do nothing since the slide is fixed to the box.

It's as if once initially installed, the extra tab was peened or hammered/bent in there...

Does that extra tab face the inner wall, or the drawer?

The extra tab goes into the inner wall of the box. Can you see my photos? It shows everything. They are showing up on my computer...

Yes I can see your photos. I was looking a photo #3 trying to figure out which slide is which. Is one of those a left and the other a right?

No. Both right side. The top is new. The bottom was the existing one I ripped out and you can see that extra tang that is giving me problems....

OK...if you extend the slide out, is there a square window that uncovers the center tang?

 

[Mohawk Dave]

Yes, in photo #4 I moved the slide forward and you can see the problem tang. If I move the slide back a little I would see the center bayonet.

OK...if you extend the slide out and align that window with the center tang, can you push the center tang away from the inner wall with a screwdriver?

No. I have 2 tangs near the front of the slide. One goes downward, just like every other slide, but the "extra" tang next to it goes upward.

The slide is literally locked into the inner box wall.

Do those extra tangs look like they're intended to be bent for removing the slides, or are they too stiff to bend?

 

[tjmonsen5]

Its actually quite easy to remove the slides with the correct tool. The official tool looks like a flathead screwdriver, bent 90 degrees. You probably have a large 90 degree pick in your toolbox. Think the large mayhew or craftsman professional picks. Stick the pick in between the slide and the box, pointed end down. Push up on the handle of the pick, forcing the slide away from the box. Once it pops, push up on the end of the slide nearest you. It will pull out.

 

[Mohawk Dave]

That doesn't work. The 2 tangs are in opposing directions and they are locking the slide into the box. One goes up and one goes down and you cannot pull the slide away from the box because of it.

Hopefully this doesn't confuse matters...
Installed a second set of slides on the bottom drawer of my KRA4107 a couple of months ago. What seemed like an intuitive procedure took way longer than it should have. The outer slide that affixes to the box wall needs to be installed with a slight arcing motion, and the slide will need to be removed the same way. To remove, lift front (outer part) of slide up while pulling inward and it should come free, no need to apply any great force. I don't recall that extra tang like you are showing in picture #3, maybe my new slides had it, maybe not. To install I had to get the farthest (inner) tab lined up, then lift the front (outer part) of the slide slightly while pressing in on the inner part of the slide and then drop it down once everything lined up. Everything has to line up just right to get it to drop in place and there was no need to apply a lot of force to anything.

 

[Mohawk Dave]

and if you do try to force the slide away from the box it bend the **** out of it because you have 2 tangs that are in opposing directions locking it in

 

[Mohawk Dave]

Ok. these are not regular everyday slides on here. I have many boxes and I've never seen this. I can't even find a thread on garage journal with this problem. I've changed many slides and I know how to do it, but these have the extra Tang I keep talking about

 

[j.c.whitney]

If I had to guess, I don't recall that extra tab on mine. I can go pull a drawer if needed to confirm.

 

[CWP1616L]

Are those extra tangs the same stiffness as the bayonets? In other words, are they intended by the engineer to be bent for slide removal, or not?

Trust me. You'd remember this SOB. My replacement slides don't have it. And I'm quite certain this is factory.

 

[Mohawk Dave]

Yes, same thickness. The only possible way they could have been installed is by a machine that could manipulate that "extra" tang, because it is longer than the opening it resides in.

I just drilled one out, and finished off with a cold chisel. PITA...

 

[CWP1616L]

Is that center tang in picture #3 bent, or is it supposed to be like that?

 

[j.c.whitney]

I'll have the part number of mine in a minute...

 

[j.c.whitney]

8-05288ALRS is the part number of the slides.

 

[Mohawk Dave]

I have the correct replacement slides. They do not have the "extra" tang either.

ANYBODY KNOW A TRICK TO REMOVE THESE DAMN THINGS?

 

[warmpancakes]

snap on makes a tool for doing them, Ill post a photo tonight, its basically a 90 degree pry bar,

Funny, when I asked a question about these slides, not a peep!

See my "fancy" drawer slide removal tool, part of a very cheap plastic pry bar set from Princess Auto. 2 views of it in pics 1 & 2. Pic 3 shows it "installed" in the removal position. Lift up on the end of the slide in the direction of the black arrow. Pic 4 shows the pivot points in yellow circles.

On the bright side, you've answered my question.

 

[Mohawk Dave]

ok, you got the same tangs I have.

I know how the bayonets work. But getting that upward facing tang out doesn't work with a 90 degree pry, because it is up in behind the inner wall. I can not get the slide low enough to release the tang, because said slide stops b/c of the front bayonet. They have been interlocked...I can not move the slide up or down to release either the tang nor the bayonet.

Clear as mud?

 

[j.c.whitney]

Are you the original owner of the box? Speculating that someone used a punch to bend hell out of the upward facing tang once the slide was installed? Can you get a jigsaw blade through there and cut it off?

 

[toolfreak]

I ran into this last week helping a friend replace a couple slides on his snappy box, a lady's foot bar works great. Some people call them a heal bar. All you do is pry it out just enough where the tab faces in to clear the frame of the box and lift up on the drawer slide. It's very simple once you figure it out, I was confused at first because I have never changed out a slide with them on it.

 

[Mohawk Dave]

Alright...got them. used a big ole Stanley flat bar. Had to hammer it down there a little and pry pretty hard. What a crazy design...

It looks like your upward facing tang is seriously bent, at least on the slide in your pic in your original post. Look at the pic in my thread, that's how they should be. The plastic pry bar is forced inbetween the inner wall and the slide, creating a small gap that releases the lock. Look at how the other piece of the slide is locked onto the drawer. If yours are all bent in like that, you're going to have to pull them out if that's possible, or cut them off with a small cutoff wheel.

yea, i bent it a little more to show up for pics. But there were some pretty bent in in there. New slides are in and screwed off. Thanks.

 

[Mohawk Dave]

I'm surprised that there's not more of this question on Snap On Journal.

2nd owner. Military owned first. My thoughts precisely. Punch or similar used. No room for cutting of any kind. Drill only with 1/4" drill.

 

[MikeF2316]

Think of how much easier it will be next time!

 

[dr_clyde]

I had the same problem. I used a largish prybar. Major PITA. Next time I'm making by dealer do it for me. Very poor design.

 

[CWP1616L]

Looking at Mike's picture, it looks like one tang faces up while the other faces down; is this correct? Is there TWO tangs in that circle?

 

[Mohawk Dave]

no, just one tang, but if someone punches it in, it's a mother to get back out.

The other piece of metal is curved outward, so your prybar will theoretically hit that and create distance between the slide and the inner tool box wall, thus allowing the tang to be set free.

OK cool... gotcha. I don't know if my box has those type of slides or not, but if it does, I'll be better prepared. Thank you sir.
