Blower Motor in a Peugeot 306 had siezed so I figured I'll fit new bearings. Pulled the armature apart and found it has sprung mounted bushes and not replaceable ball bearings. Once I cleaned away all the dirt I can see a felt pad inside the housing so I figure it's unlikely to be there for lubrication as there's no oil hole in the bush to its centre. So I've lightly polished the rust from the shaft and inside the bushes with fine wet&dry emery and am now wondering what type of metal to metal lubrication, if any, to use.
Silicon spray?
Graphite?
Nothing?
