thicker sprocket nut worth a check

[tommyardin]

Been experiencing grinding sounds in the chain department and a quiet knock on corners; thinking it related to the winter road crap and salt (how much lube do I have to throw  at this not year old chain ffs) I figure a clean is in order.




Removed the front cover, loads of crap around the front sprocket so the scoop out begins and suddenly once enough crud is removed to my horror the the sprocket wobbles.




The new wider nut has come off. I found the lock washer down below which had been bent round the nut as required   


but some how flattened off.










I replaced the chain and sprocket in May, torqued correctly (imo) to the spec suggested for wider  nut.

Hey Midden!
I bet when you started this post off you did not realise it would go on so long.
