sprocket and stuff

[coffee]

Put it all back together  today,got to admit I put the original nut and washer back on,I never gave it a thought 'till I seen the post,hopefully it'll be ok,I've never put a new nut on any other bike,but obviously it's the thing to do.While I think about it does anyone have a problem putting the rear wheel back on their own?(gen 2) I always have a right game with that poxy caliper bracket,by now you're probably thinking "can this joker do anything?" I really don't normally have probs with working on my bikes,in actual fact I enjoy it,I only do basic servicing and cosmetic jobs,I wouldn't start stripping engines and box's etc.It's just that this particular job has been a ball ache what with not putting the cush drive rubbers in far enough and then couldn't shift the sprocket nut,can't win 'em all ay?still thanks for your replies it's always reassuring to know there's someone who'll help you out. :thumbup :thumbup :thumbup :thumbup

[size=1em]Hi Coffee,[/size]

Below pertains to the FZS600 and I do not know if it applies to the Mighty 1000


Yamaha have had serious failures with the nut coming loose on the out put shaft, so they produced a 12mm think nut as opposed to the 9mm standard nut,the 12mm nut also has a slightly deeper recess on the back of the nut.
[size=1em]I would recommend you purchase a new nut and lock tag washer, if the old one comes loose it wrecks the spline and thread on the end of the gear box output shaft, resulting in a full engine strip down and rebuild fitting a new output shaft, which is likely to cost more than the bike is worth.  [/size]

I do get the damage that would arise if t his nut came adrift but I don't know if the 600 is the same but the locking washer locates on the shaft like the sprocket itself then is knocked over as usual ,once tightened I would have thought it very unlikely to be able to work loose without the tabs on the washer breaking ( both of them) and this in itself is pretty unlikely. I'll certainly keep an eye on it though. :thumbup
