Got a problem with the clutch in a Vespa P200E the castle nut has come loose again. It happened months ago and it's happened again. The clutch was slipping abit so I opened it up today to find the clutch was loose. The bit where the clutch lock nut locks into the crank snapped again like it did before. I am torqing the nut like it's meant to be. I've never had this problem I've replaced a lot of clutches over the years. Any ideas why this keeps happening

I would switch to the hex nut most folks are using these days and ditch the castle nut you may be able to get it tighter

I second Hibbert's suggestion. Ditch the castle nut & cage, they are difficult to torque correctly; and a high chance of failure. Instead use a hex nut and star lock washer. Bit of blue loctite is good insurance. DRT, BGM, and others offer good options.

Do you have the oil drive gear installed between clutch & bearing?

Are you using 7-spring clutch or Cosa2?

I'm having problems quoting your post it's not working. Yes the oil drive gear is in I had to use the gear from a autolube PE because I couldn't get the right size spacer washer. The clutch is a 7 spring one. The start lock washer I'm having problems finding and the hex nut I can only see ones only for cosa clutch
