HOWTO: Chain and Sprockets replacement

[YamFazFan]

Take the sprocket cover off and if you can see any thread at all it's the old type nut.
The new one is flush to the end of the thread.

I can see about 3 threads visible on the end of the shaft,so I guess that's answered that one!.

At least the nut is still there.

Yep it's definitely still there .Just had a look at my upgraded nut and I can count 5 or 6 threads in it,so if this finishes flush with the end of the shaft when fitted,that must mean the original nut has approx. 3 threads?.

I'm not sure exactly, but it certainly wouldn't appear to be enough for the job that it is doing in my opinion.

It's an odd 1 isn't it.you'd think the original design would be pretty standard across the range,or if in doubt beef it up a bit to start with.
