Bearing, gear cluster outer track
MBL0218This bush sits in your casing and the gear cluster and bearing runs in it.
They rarely wear because they should run in oil all the time, but if they do wear they are hard to remove so they are not often changed.
If your cluster has a lot of movement then change it, there is a rare workshop tool to do the job or the spanners manual shows other ways.
Or try an good Lambretta dealer to do the job.
