I have a motor in my Telefunken Reel to Reel and it was getting really hot and someone said to take it apart and clean it because probably the reason it was overheating was due to dried greas in the spindle. So now it is cleaned but having not that much experience with electric motors, am I suposed to use Oil or Grease? Also where exacly am I supposed to put it,, inside where the large round piece turns inside the transformer? or on the bearings or both? bhedberg21@hotmail.com

Hi,
Most of those types of motors use a sintered bronze bearing on each end of the shaft, and sometimes they have a felt wad to hold oil, and sometimes not. In either case, they use a lightweight oil. "3 in 1", Labelle lightweight oil, sewing machine oil, all are close tot he same quality as the original oil, and will work.

Sometimes this is only a temporary fix as the sintered bearings were originally heated, and then dunmped into an oil vat where the pores deep within the bronze absorbed the oil so it could be released later.

If the bearings are ball bearings, or roller /needle bearings, a very lightweight grease is in order.
