Chain Slider Wear Fix

[grayracer513]

Here's an another approach I came up with for the problem of the chain slider causing wear to the top of the swing arm. It seems to work really well so far. See what you think.

Slider Wear Fix

all you have to do is silicone the slider to the swingarm. If the sand cant get under it it can become an abrasive.

The only concern that I would have is that the metal would cause premature wear of the chain.

Question. Will the Swingarm still accomadate the slider on top of your repair piece?

Is it sand that is causing the wear? I just replaced mine on my 03 and although the slider was worn out, there was no grooving on the top or bottom of the swingarm. We don't have much sand around here.... ?

No, not necessarily sand and dirt although it doesn't help matters. The slider will actually move back and forth rubbing the swingarm in the process. I have put one-sided sticky foam tape under mine and it has stopped the wear. It was a really bad problem on the earlier 426's when they used screws instead of allen headed bolts to hold the washers down that held the slider in place. The allen headed bolts allow you to get it a little more snug as well as flattening out the cupped washers so they hold the slider tighter to the swingarm. This stainless piece looks like a pretty good idea and will last longer than the foam taped I used. I think I might give it a shot. ?

I use outdoor or automotive "Goop." It lasts much longer than silicon/caulk.

Yes, the stock slider goes back in place on top of the wear plate. It can shuffle around all it wants and can't tell the difference between scooting around on the steel shim and how it was in the first place. I just bolted the plate in place as in the picture to hold it firmly in place while the sealer set up. Don't run it without a slider.

Sand is the worst, of course, but anything that gets in between the slider and the swing arm will cause this over time.

I actually found a use for the garbage stock tubes in order to fix the problem. Cut three strips out of the tubes and siliconed them to the swingarm. Works like a charm.

These wil both work too, but here's why I rejected them.

Strips of inner tube are still a lot thicker than a 24ga steel shim, and I didn't want to lift the slider into the chain path any further than necessary.

Simply glueing down the slider seems less durable, because the slider is so pliable that, even with the washers modified to hold it in place, I was pretty sure it would be worked free of the adhesive in between the screws and require periodic resaealing.

This way, the screws hold the wear plate in one spot, and the slider moves around on the steel, not the swing arm.

Maybe I missed this but if you use the stock bolts/mounts on the swingarm to bolt the metal strip down, how to do bold the slider down?

[stevie]

It is not sand or mud that causes the swingarm to have a groove worn in it. Its the fact that the chain slider takes a beating from the chain (chain slap) and this makes the slider rub on the swing arm and make the groove.

BTW merely siliconing or gluing the slider to swingarm is only a temporary fix and will only last a couple of rides. Even with the tops hats modified there is still a problem.

The SS strip sounds like a good idea to me.

After the glue or whatever you use has set you remove the bolts and put the slider on then bolt the slider on.

i've got the T&M designworks chain glide and siliconed it about 6 months ago and its still stuck on there as good as day one! if you clean every thing and give it time to dry and use a quality 100% silicone caulk i don't see how its only lasting two rides? ?

say what? After owning and using silicone on 5 YZF's over a period of 3+ years I can state with absolute certainty that you are wrong.

Never heard of sandpaper huh? The sand acts as the abrasive under the slider.

The 04's still have the same silicone on them that was put on a year ago. It will last for many many rides. If the sand cant get in there will be no wear.

Well, you're right about the use of the bolts and remounting the slider. They are only there in the picture to hold the plate in place while sealer dries. You could probably just assemble it all at the same time, with the shim under the slider.

But you're dead wrong about the sand thing. Try this: rub a piece of hard rubber on a piece of aluminum for a week or two and see what you get. Now throw some sand on there and rub that around with the same piece of rubber. See the difference?

The Design Works slider will stay put with or without sealers becase it's so stiff in the first place, and it bolts down hard, instead of being designed to slide freely. But, like I said, it's expensive and it's loud.

..... like I said, it's expensive and it's loud.

The new ones have a rubber piece stuck on the bottom and they're much quieter than the old ones. Neat idea with the metal plate. ?
