Answer
Jonny,

According to the factory manual the rocker shaft assembly is held together with a "Mills Pin".   In the US we'd call it a roll pin.

In order to remove it you need to support the end cup so that one of the pin ends is pointing down into an open space.  Drilling a hole in a piece of pine and positioning the end cup over that hole would probably work.   

Again, in US speak I use a pin punch.  I suspect you might call it drift (0r small diameter drift) that's the same diameter as the pin.  Softly tapping the drift with a hammer should push  the pin out of the rocker shaft/end cup.

When it's time to put it all together you're best off getting a new pin.  Support the end cup again (no hole in the block needed) and get the hole in the cup lined up with the rocker shaft hole. Again, a gentle tap with a hammer should get it all back together.


Cheers,

Jim
