Good morning, forgive me if this has been covered before but I’m in need of expert advice.
I acquired my 2004 Vespa 200GT as a ‘project’ and the vari & clutch we’re in a box of bits. The clutch was built up and looks ok. My questions are these:-

There is about 5mm of ‘in-out’ movement on the shaft from the reduction box-is this normal?

When the clutch is fitted to the shaft and cover Fitted the nut is then fitted and torqued up against the bearing inner race-this seems strange to me because any movement in that shaft will put stress on the bearing-in the parts diagram that I’ve been looking at it looks like there is a bearing (483261) behind the clutch that acts as a spacer. However I purchased this bearing and it doesn’t fit!

I suppose what I’m asking is do I need a spacer or does the clutch just fit on the shaft-am I over analysing the clutch on shaft arrangement?

Thank you for any help or clarity you can give me regarding this.

Yes.

There should be a spacer (thick washer) between the clutch assembly and the transmission case. Part no. 274246. Without this you'll crack the transmission case...

Thank you Jimc-I knew it had to be something obvious but it just wasn't obvious to me!! If it had been me who'd stripped it in the first place I may have remembered.

Hopefully now I can get all the bits back together and the scooter mot'd just in time for the summer to be over!!

Thanks again.
