2013 GSW 10 klm Blown Gearbox & Engine. Seized back wheel.

The clutch hub nut is usually torqued to a high value on most bikes, so if its assembled correctly I'm hoping this would not be a common issue. If however the nut loosens over time because the shaft floats, that would be a very big deal.

Just been looking on the BMW service DVD and its a 2 stage tightening sequence

1st tightening torque, 170 Nm
Slacken, nut, angle of rotation, 90°
2nd tightening torque, 250 Nm

Then this bit is the interesting but that could be the cause of the problem maybe a bit slow in the factory ?

Note

The nut has to be tightened to the final torque within one minute of initial engagement of the threads, because the thread-locking compound starts to cure rapidly.
 
Surley if the back wheel locks up thats an abs problem you can point out to the dealer too:clap
I have a wc gsa on order so fingers crossed:bow

Hmm interesting theory...perhaps you would like to elaborate?
 
Sell it and get a mint old 1150 Gsa like mine was until last friday when two of our eastern european non tax paying comrades decided to take it out on a roundabout and leave it for dead, but oh no she aint dead yet looks pretty rough but still starts runs and has no nuts falling of its clutch!! I cant see that being the story after a wc Gsa takes flight up the tarmac perfectly upside down, :thumb2
 
I've printed a copy of this thread, and attached it to my will, should the worst happen.:thumb

come on fellas,just cos YOU know the mechanics of the bikes,:D
theres a lot of riders have absolutly no idea,it is just modern lifestyles.
this keeps the modern economy rolling.:thumby:
you buy i fix:thumby:

Was doing the same thing, though I don't see the note about the threadlock. The clutch cage to balancing shaft attachment is a single 36 mm nut torqued hugely rather than multiple screws running into a flange.

So the problem is not the hub to layshaft (150 Nm) since the layshaft runs inside the balancing shaft and would only affect the transmission, not the camshaft stuff the OP says was wrecked. The engine animation shows the balancing shaft running the rest. It would definitely make some strange noises as the cam chains started to eat their way through stuff.
 
Well, my deal is done. I do not want the bike back again!

Also, they repair is going to take quite a bit of time, as BMW instructed the dealer to take the whole engine apart to see if there is any other residual damage.
 
If the gearbox self destructs and locks up, what difference will pulling the clutch in make?:nenau

It's not a case of the gearbox self destructing, more a case of being jammed by little cam chain components dropping into the meshing teeth. If the engine starts making funny noises the idea is to de-clutch and kill the engine hopefully before the cam chain self destructs and locks the gearbox :D

Don't know about yours, but every LC engine I've heard, including mine, makes nothing but funny noises?

How much warning will you get when the clutch nut comes loose?? :nenau

Exactly mine sounds like a bag of spanners so must sound really bad when it goes wrong
