I need to take off the pulley at the back of the drum on a washing machine, it is held on by one of these torx head things but it aint shifting. I tried wedging the pulley to stop it turning and applied as much pressure as I could without slipping but to no avail. I dont think thumping it with a hammer will do the bearings much good so not resorted to that yet. I suspect it may have thread lock applied to it.
Any ideas?
