This is the result:

Yep, a dismantled Harrison Aircon compressor clutch to get at the idler bearing

The job started with a bit of lathe work to make the puller tool seen in the foreground from absolute scratch. It's not pretty but it did the job. By golly the front plate was marvellously tight on the shaft

The main part of the pulley was a relatively easy pull using a three-legged puller but the bearing extraction itself needed the press and an old Xantia front wheel bearing as a mandrel...
Not a bad afternoon's work... I'm happy but now completely exhausted
