i've worked in manufacturing building box fans from start 2 finish and i think i could still build a fan but these motors are set in machine i know about bushing and brushes and cant understand how a motor build over 50 yrs ago would still have grease or oil around the bushing we built motors that never had to bo oiled but then they were throw away fans
also ive been sewing for 57 yrs so i guess what i need to know do i leave the motor shaft in the machine and just take motor loose. i ve cleaned it up some and used t f and greased all gears i also have a manual .Miriam machine runs slow w/wo fabric,bobbin winder works ,where is top bearing ? fans and vita mix blenders we built only had one bearing or bushing , i got this @ thrift very cheap and i believe i can fix it im going to!and make it work
