I have 2 on the bench an S and a Z I think. One has very good motor but broken fan, other has dodgy motor good fan. Dodgy motor was seized, I sprayed sliicone spray into top fan housing to final get it going as no amount of spinning etc would free it up.
1. What is the best lube for the fan motor, and is there any other method than sprayin into the fan to lube?
2. Is it possible to change/remove/replace just the fan turbine?
thanks for your help, merry xmas.
