Front Sprocket

Go on I give up.  What's the secret of the getting the front sprocket far enough on the shaft to get the lock washer on?  >:(

I had to dress my lock washer on some very fine emery cloth on a flat surface for about 10 mins, then it would slip on and turn just nicely. Easy!
 
I heat the sprocket up until it is almost too hot to touch and then it gently drift on.
The lock tab is sometimes a bit chewed up too and may need dressing.
 
The external corners on the sprocket splines need chamfering then it will slide on, you don't want to be hammering anything.

remove the sharp corner edge on the internal spline on the sprocket with a pencil grinder
does not require much, just need to put a small radius on the edge of the spline and the sprocket will slip straight on
the sharp edge fouls the bottom of the spline on the shaft

i really love to watch them roll.                          :D

Going back to your first question:
I just had the same problem.
Sprocket went on OK, but not enough clearence to get the lock washer to turn on the spline.
Ended up destroying the lock washer trying to bash it into place!

I am not a mechanic (in any way, shape, or form), so I ended up turning down about 0.5 ml from the centre of the new lock washer to make it fit.

Hey! That's cheating! You have used the 'search' function haven't you?

As I said, a bit of patience and emery cloth and the lockwasher will be thin enough to turn and lock.

 
I found that an easy way to actually get the washer to turn (after I'd relieved the back of the sprocket and flattened the washer out, thanks) was to use the old sprocket with a couple of bolts just sticking out through the fixing holes.  Push it onto the washer and just use a screwdriver as a lever to turn it - was surprised how easy it made it.
