Supposed to have oil in it, but not be 'full', however it will be if you tip the scooter on one side as it can flow through the bearing. Sounds like the least of your problems :)

remove gears, (keep in order) put a spanner or flat bar through the slot in the layshaft to give you something to grip onto, and use a 14mm spanner (I think its that size off me head) on the flat of the selector rod ..IT"S A LEFT HAND THREAD. undo, remove rod and cruciform, repeat in reverse, with a drop of locktite on the rod to keep it nice and tight on the cruciform.

Should slide out now, but they get burred and stick in there.
You will need to force/persuade it out of the shaft.

yeah, they can get burred on the end, I put a small chamfer on the rod to stop this happening.

It is recommended that you replace the rod and the cruciform anyway, as long as you can get it of the cruciform & out of the drive shaft. Just make sure you buy original Piaggio parts, do not be tempted to buy the cheap shite otherwise you will be doing this job again in about 6 months.

If the cruciform is that bad, I would also be checking the primary and each gear cog. If you have dropped the engine remove the whole lot and give your primary a shake and check all the rivets are ok.
