Sprocket change disaster

Post by matt1966 »

I wonder if anyone has ever done this. I changed the sprockets today +2 on rear -1 on front job was going pretty well till I was tightening front
sprocket bolt it didnt seem to be getting tight then it very loose I had managed to snap the bolt wtf, then I had the great job of trying to get the snapped
half out of the shaft wasnt too bad luckily anyway thought this would be a part dealers would carry but not so. Anyway have ordered one hopefully will come
tomorrow.

oh dear... mustve been fatigued anyway... just as well it went when you were tightening it & not out on the road, otherwise couldve resulted in a smashed casing, wrecked slave cyl, bent output shaft etc... dunt bear thinkng about lol.
You do not have to say anything. But it may harm your defence if you do not mention when posting something which you later rely on in quote. Anything you do say may be ripped to sh*t.

where it is.

No not too bad the hole in shaft is a fair bit longer than the bolt, so while I was drilling it, it spun down to the end of the thread, got an eaziout in there and came straight out. All finished now took her out for a quick blast and loving the space hopper front end lol
