Front sprocket came lose
I just had a wild idea to go from 15 front sprocket to a 14 because why not and I mostly drive off ...
When I tried to unscrew the nut holding the sprocket I was surprised that the the nut came lose with my fingers !!!
The safety retaining washer was in place (sort of) but how can this happen ? I've seen the person who tighten it with an air wrench and I said it will never cause problems that was maybe 5k km before maybe less.
I've changed the sprocket the shaft was in pretty good condition and I've tighten it with a good wrench that I have and I've bent the safety locking washer.
Is this a nut that I have to check regularly ? I don't want to mess up my gearbox shaft because of this ...
Really intrigued what could have happened ? It wasn't tight in the first place ?
