If only that was possible – the bearing housing is buried inside plastic in the back of the drum housing, no way to wrap a cloth around it. I have considered heat as it’s something I’d normally try with bearing removal, but at best I’d heat up both the housing and the bearing – maybe worth a go as the expansion might help to crack the corrosion and I’ll get a bit of differential expansion as I think the housing is alu, whilst the bearing is steel (checking the figures, just as much from that as just heating a steel housing), so thanks for the thought.
