So looks like a new swing arm or see if i can get it built back up with weld

I'm going for a whiskey or 6 now !!!!

Hm, bad luck:(. I wonder if the plastic protection thingy there (spare part 11D-F2151-00) should protect the swingarm from such heavy damage. Rtwpaul has the same damage btw.

Bad luck - that really is a bit of pain in the ar5e Phil. :Christo_pull_hair:

It has happened before and seems to be attributed to riding for any significant length of time with the swing-arm past horizontal (the rear axle above the output shaft and front sprocket). More often than not it is due to either one, or a combination of: saggy OE Sachs shock, fitting lowering links or being heavily loaded for extended periods.

It will protect it, but only for a very short time if the chain is permenantly dragging along it. The protector is only really designed to prevent damage from chain-slap and occasional bottoming out.

Yep. His was down to riding a big distance on a knackered shock whilst carrying a heavy load.

Do you know what RTW Paul did to sort it , Weld it or New ????

Cheers Phil

�450 ooooooch

Cheers fridolin
I'll have a go at the Italian one but worth finding out how much the post from Aus would be , at �210 new sounds a great deal

Phil

Happened to mine too .Too much weight for too many miles with a knackered loose chain. I think Paul said it couldn't be welded. Mine wasn't deep enough to concern me too much so I filled it with chemical metal. Been good for about 20,000 miles. I keep an eye on it now though. http://i1200.photobucket.com/albums/...2/IMG_4653.jpg

It says $245 postage:(. So get the Italian one.

Cheers Brian that looks fine to me :woo:did think about the chem metal !!!

Yep fridolin looks like the Italian one then :italy:

I concur with Brian - A chemical metal repair is probably worth a shout. RTW Paul couldn't do this because his was worn so far you could see the needles in the bearing!

I've used Devcon to repair alloy and aluminium castings with pretty successful results. My father-in-law introduced me to it a number of years ago when he worked on Rolls-Royce turbines in the off shore gas industry. I thought, if it's good enough for that, it would do for me!

However, if you can get hold of a swing-arm at a fair price, then that would probably offer better peace-of-mind in the long run.

Cheers Pleiades
The Italian arm has 13 days to run so i sit on it and try the epoxy

Phil

Have it welded .... not even a hard one...

I'll have a look here in rural France but they're still eating their own young in these parts !!!!
:unibrow:

OK , update !!!!the Italian swing arm is on it's way but as the bikes up on the lift and can't do much i got to thinking !!!! dangerous i know !!!! but

Whats the standard dog bone measurements ?

Mine are 126mm centre to centre

Reason i'm asking is if the guy before me put shorter ones on to lower the bike the angel of the swing arm would surelly lift causing the chain to catch earlier , ok i know mines was knackered but could this be a factor or am i waffleing blowup

Phil

Standard links are 126mm. Fitting lowering links will do exactly what you suggest.

I've fitted adjustable raising links to mine and run them at a mediocre +15mm. I didn't do this to raise the rear as such, but to keep everything in line better when loaded up.

Cheers mate , should have read your post properly first time :075: do like the look of the Quad jacks , simple but effective

Phil

Phil, this seems to be a problem with a couple of Yamahas when the suspension is either too hard or too soft (wears either top or bottom of the slipper), combined with a kinked or too-tight chain and/or a smaller front sprocket. It doesn't take much...

References: I chopped out the top of a 426 slipper in 400km:fight:. Also, WR250Rs are noted for chewing the bottom out of the front slipper if the chain is too tight (even slightly), or a smaller front sprocket is used.

Imo, run your chain a bit loose if you can (watch out for derailment), with stock front sprocket and correct spring rate for load.

Sorry if I'm preaching to the converted. Just my experiences, that's all.

Hope you get it sorted mate.

All advice more than welcome 66T , swing arm arrived this arvo from Italy and got it on !!!
Bloody amazing really !!!! ordered the arm from Italy and the cush drives fron the UK at the same time !!!still no cushes :eusa_whistle:

Hmmm... Might be karma, mate. If your bike is an Italian one like mine is!

I bet you're relieved to have the s/arm in. Amazing that there was one for sale just when you needed it. I'm seriously thinking of buying a spare front slipper and carrying it if/when I go away. That 426 effort was nasty. We were on a big trip on the way to the Simpson desert. Someone suggested poly pipe as a repair, and b&&&&r me, there was some lying in a creek. It lasted > 2000km!

Sometime the simple things are the best

Carring a spare slipper wouldn't hurt on a long trip , weighs nothing and could be zipped to the frame somewhere

I looked all over for a s/arm
