[McMurdo]

After I left home my mum employed a cleaning lady (!). One day she rang and said the faithfull Electrolux Dolphin had started smoking while the cleaning lady had been using it on 'superboost'. I went round and stripped it down and found a motor sleeve bearing had seized and been spinning with the shaft, setting fire to the felt oiler. I rang the wholesaler and was told they did a 'compatible' motor made in eastern europe for around 20 quid. I fitted it and found it had ball races instead of sintered bearings. it ran perfectly for years after.
