Sliding Shoe Broke- chain adjustment

[MonsterDark]

So i posted in the other site...but i have a feeling i will get a better response here.   so maybe some of you have read this already if you even check it out any more.

My friend insisted that he tighten my chain, in doing so he cracked the sliding shoe inside the swing arm. I've posted in the parts wanted section looking for this part, but do you guys think i could fix it with JB weld ?  (jbweld.net) 

I haven't called the dealer yet to see how much this part is worth..   do i risk injury riding my bike like this? It's at it's full adjustment so it should be able to slip or losen as the pressure is holding it together.

cheers

I don't think JB is going to do the job.

Just for example, the sliding block for an '05 620 is $33 from Ducati Omaha.

Those blocks pop on on ebay regularly.  Also Motored-Sports (chris) on this board will probably have them since he's dismantled a few bikes and I don't see them being the highest demand item.

But I gotta ask - WTF was your buddy doing that he busted the shoe?  Your chain shouldn't be so tight that you actually have to put any real stress on that assembly.  With the chain properly adjusted you should be about to move it ~ 2cm  either side to a straight lined traced from the outer edge of each sprocket.

Did he not bother to loosen the axle nuts?

When you say it's at full adjsutment it makes me think it's jacked all they way to the back... And that's not good.  You're putting a lot more stress on the chain which can cause it to fail.  Also a lot more stress on your output bearings and if those crap out... you'll be really really sorry.

Yes he losen the axel bolts, and yes it was at the very end of adjustment, but my chain is so fawked that's it's still lose ( new one on the way with new sprockets )  He said he didnt put extreme pressure on it, but obviously enough

$33 dollar definately out ways the thing of JB weld..

i've emailed Chris havent heard anything back yet.

Well, I wouldn't ride with my chain all bollixed up.

I know I don't know your buddy at all - but something sounds off here.  IF the axle nuts are loose you should need any force at all to move the adjustment blocks.

patience... it's only been a little bit man!

Get a new one..........and don't let your buddy(s) adjust your chain.

yup i have patience didnt mean to have it come across any different.  I told my buddy that there was no more adjustment left, he insisted there was ( have had been working in a bike shop ) guess i was right, and yes i'm not going to let buddy's work on my bike going forward. Hoping he will split or pay for the bill of the replacement part.

They are not 'uncommon' to break. 

Another thing to watch, is when you get the chain straight, and at the correct tension, tighten the axle nuts first, then snug the adjustment screws - DO NOT OVER TIGHTEN.  If you are worried about them comming loose, which also does happen, drill a little hole through the bolt head, and safety wire it to the swingarm.

Did you draw that just for this thread, or was it in your 'parts bin'?

[MonsterDark]

so i went to the Duc dealer, and they dont have it in stock, which means it's a order from Italy and a minimum 10 days.  Price wasn't too bad, was expecting more $40 (i'm in Toronto Can.)  He's suppose to be checking some thing else out and phoning me back..

thanks for the tips next time around
