This insulating gasket may also fit Lucas mags - if truthful I have not tried - so email to check for details if you are looking to change bearings on a Lucas magneto.

To fit, heat magneto bearing and old bearing should drop out (i.e. destroys old gasket).  Then place bearing in freezer, fold ears on bearing washer, place magneto body (or end casting) in oven to get it warm and then pull bearing out of freezer, attach to washer (you can use cyano glue or similar to ensure it sticks to face of new bearing) and very quickly push it into the bearing recess in the magneto body.  Use an aluminium drift with an inner shaft (or bolt screwed in, then head removed)with diameter just less than inner bore of bearing to feed the bearing down the body of the magneto when fitting, this can also be gently tapped when bearing fitted to ensure it is fully located home.
