Absolutely gutted :(

I was trying to clean all muck and grease off the arm where the chain rests and tried to remove the 2 torx screws off. First one nearest the rear wheel was fine. To my surprise, as I turned the ratchet the second screw snapped-off clean. I noticed this chalk-like sediment on the screw and some of it dropped resting on the swingarm from the sheered off screw. Pic attached. Left screw is the OK one from the attachment point nearest the wheel for comparison.

I've not even attempted to try to get the threaded broken bit off as I don't know how to. I can feel that it was screwed in to the point that you can still feel the end on the other side.

I feel like I have to take it into the dealers at this point. I've still got about 1.5 months left on the Approved User Bike Warranty. I've had a look at this microfiche:
http://www.ascycles.com/Illustrated_catalog2/MicroList.aspx?id=51596&catID=33&catname=Rear_axle,_rear-wheel_drive,_control&bindName=REAR_WHEEL_FORK&bindCat=33_1442

I'm in a panic about whether or not it's the case the whole arm has to be replaced and if so, whether or not it can be done under warranty.

Does anybody know if the sheered-off threaded bit can be removed somehow?

Cheers,
Lab.

Don't :tears

Just drill it out carefully OR take the chainguard off and liberally apply WD/penetrating fluid to the stuf and there might be enough thread to get enough purchase, to remove with some mole grips

It's not the end of the world:blast

What he said :thumb You will also find that the torx bolts holding the front mudguard seize up too - all the excess salt on the roads
 
Cheers Guys...

Sounds silly but if I've got a multi-tool or needlenose pliers I can save myself some money and use that instead, right? And presumably I use the pliers from the other end of the guard where I can feel the other end of the screw? -I reckon I can get good traction but it'll be awkward. :(

-I haven't got a drill, unfortunately.
 
Gutted?
In a panic?
Take it to a dealer? :blast

Calm down man!!!! :rob

It's a half an hour job for anyone who is capable of doing basic bike jobs......I very much doubt it will be covered under warranty and a dealer will charge you a bloody fortune
.......where about in London are you?

I'm sure a local tosser would help you out, or if you're close to Roehampton Vale, Steptoe is there and he'll take the piss out of you while he does it, I'm sure :thumb2

No need to panic though, you'll be fine :comfort

EDIT......just to clarify, this is the plastic chain guard isn't it?
Unless I've got that totally wrong, you could even tie it up with the biggest cable tie you can fit through the hole in the plastic, go around the swing arm and back up underneath and pull it tight.
You should be able to make it completely safe to ride, then you don't have to worry.....It can be done at your leisure, or when Steptoe can fit you in if you can't face doing it yourself :)

If it were mine, I'd borrow a drill, drill out the broken end of allan screw then replace it with a stainless steel nut and bolt so you don't have to go through the hassle of tapping out the old hole.

Forget half an hour, that's a ten minute job max :thumb2

If it's awkward take the wheel off to give yourself more room

Use plenty of lube:censor:

Narrow Mole grips might be better
 
Thanks guys. I've just had another shot at it whilst it was still daylight but it looks pretty wedged in there. Lots of WD-40 - didn't hold back ;)

I had some different thin and needle-nose(?) pliers to try and get a good grip but no joy. I did get a little bit of a grip and try to wriggle it but no joy. Fanum, yes, it is that part.

I forgot to explain the other circumstances:

MOT due before end of month;
Bike is in the resident's car park, live in a flat and haven't got any power tools like a drill;

...Surely, I can't pass the MOT with a cable-tie? And spotting a screw missing?

Thanks for the help so, far.
 
MoT-wise cable tie should be ok as there are many parts on a motorbike that are cable tied in place that were they to come loose would fail (i'm thinking brake lines etc)

I think this is the relevant page of the rule book but have a look through for yourself and see if there's another part covering fittings...

Best,

Depend on some mole grips, if you get a grip on the protruding thread it should be a simple case of just screwing it though the rear.

IIRC you will need a very slim drill to access this area to avoid interference from the footrest. When I drilled mine I used a 90 degree chuck attachment held in the chuck of another drill.

Thanks guys. That's a helluva lot more options I had than a few hours ago :) Lucky to be part of a great community.

If I went with mole grips, I think I'm going to have to go round to somebody's and tackle it from the other side of the bike (or under it?). -I've not got a paddock stand and there's not much room for me to work with (not sure if it makes a difference but I've got a lowered suspension model, too).

JayC, am I right in thinking that from the above (and I can't believe it's the same hole, too!), did you continue to drill CLOCKWISE (the 'tightening' direction) and then let it drop out the other end?

Cheers again, everyone, I really do appreciate it. I've only got basic tools and afraid I don't even have the above drill :( I think I'm going to have to reach out to someone...

...If anything, a good friend of mine mentioned things happen for a reason...so maybe this is a chance to meet a fellow UKGS-ER near my current neck of the woods ;)

I didn't drill the screw out, there was nothing wrong with it. I drilled the thread out because I fitted a hugger that had a threaded bracket. I chose to drill the thread out of the swingarm lug so I could mount the hugger securely.

If you don't drill clockwise then you are not drilling at all. You are simply taking the edge off the drill, burning it out whilst creating a burr inside the hole, therefore making the entry to the hole smaller than it should be, which in turn means your screw will no longer go in!
 
Don't let Skygod see this, we've been taking the p*ss out of him for months for doing that exact same thing to Denise's bike! :D
I will get the broken bit out in the summer, if I remember.........
