This fan has always had a squeak at all speeds, turned out to be a dry bearing on the grey side, so with the fan removed (stabbed myself with a screwdriver for good measure) I have been able to eliminate the squeak cleaning out assembly and lubricating with some medium weight machine oil. I took the opportunity to clean the commutator at the same time
The motor is now back together fitted to the open case, and running smoothly. Nothing else to do on it until the new foam appears, which was less than £3 from 'DemisterMan' on eBay.
:) Cheers
