You need tool 47 to slide through the drive side bearing and knock the axle assembly from the bearing cone, after you have removed the selector ring and the seal gubbins. Knocking the shaft end could damage the coil spring assembly from what I remember.

Thanks J Bro

So the tool is used to knock the axle assembly from the cone. How are the items refitted onto the new shaft - is it just a press fit? Is there another tool required?

Cant remember exactly but it wasn't a big deal. You don't need a different tool I'm fairly certain that the cone is shoved up the groove by the nut holding the selector on, you can push it some of the way. Getting it off is more difficult because everything is hidden by the clutch assembly you need to understand how this fits together before letting the spring and the plate come apart when you have knocked the cone off.

And watch out for the delicate lip seal that is in the sprocket housing and seals onto the cone.

Don't attempt to dissemble the selector mechanism unless its broken, or unless your very brave. It doesn't go back together very easily. I doubt you would get parts for this anyway.

Try my 2 years old book... plenty of pictures and (sorry 'bout that...) even more words.
I was working on a different problem, but stripping it down to the very bones was just too interesting to not try...
