Picture of chain slider wear to swing arm

Hey fellas, just having a talk with my mate and he is convinced that there is no such thing as the chain slider eating away at the swingarm. As he (and another brain) put it, alloy is harder than plastic so it cant wear it away. Only way it wear is by running it without a chain slider.

Pictures tell 1000 words, anyone got any?

I know i done gray racers mod before it was too late. But he is convinced that the indent there is "meant to be there" as its a perfect size for the slider to sit in.

Also he and the other bloke said using the stainless on the alloy is a no no which in part is true, however it is insulated by the silicone so i dont see it as a problem

so show me what yas got

If your friend was a big a brain as he thinks he is, he would know that it isn't the plastic that does it, it's sand and dirt that gets between. And stainless on aluminum is a total non-issue unless you ride at the beach all the time, in which case, you'll have a lot more than that to concern yourself with.

Thanks, exactly what i was after

Has anyone actually worn through the swingarm?

I know people who have had cracks develop as a result of the wear, yes.

Anyone repaired one? Maybe clad weld the area to build it up before it breaks?

I've heard guys say they did stuff like that to the really bad ones, but I ran the one in the picture as you see it from that point on for two years without a problem after cutting a wear plate to run under the slider.  I used 22 gauge stainless sheet from the scrap bin at a metals supply house:

I applied a high grade silicon sealer to the bottom of it to exclude grit, and bolted it in place with the original bolts to dry.

After that, I replaced the stock slider with the stock bolts, and it sits in place the same way the factory intended, including the ability to shuffle fore and aft as it originally did.

I did wear a hole through the swing arm.about .250" wide and 2.5" long on the inside portion of the wear.

I found it cheaper to just buy a swingarm off ebay. It was about $90 and then did the mod Grey talked about.

I wasn't comfortable with welding as a repair.

the Yamaha slider is too loose. Mine wore threw too.

no pics?

like this one?

In addition to the topside, mine had considerable wear on the underside of the swingarm so did Grayracer's mod there too.

I didn't run into any abrasive wear under the swing arm on any of mine. That doesn't deny that you did, but I don't think it's as common or severe as the wear that occurs on top. Won't hurt to look for evidence of it, though, either.

What does happen, and often goes unnoticed until it gets bad, is that the chain will saw through the slider under the pivot area of the swing arm at about 6-7 o'clock to the pivot, looking from the left side. A wear plate would only serve as a "last line of defense" in that case, and wear to the slider in that spot is something to keep an eye on.

I also picked up a spare swingarm on Ebay.

May sound stupid but i stick few slice ducktape on slider and cut it shape of slider sharp knife. Never have any wearing damage after on

swingarm.

my swing arm has cracked from the shark cornner where guys befor me didnt maintain the rubber slider i knew this when i bought the bike got it a lot cheeper because of it

 

ive just been keeping an eye on it and some day ill get around to removeing the crack and TIG welding it up along with some pad build up to replace any other worn material should look good once filed down

 

im suprised no one has put a roller in place of the slider?
