Is that bearing supposed to use grease? or thin oil. Makes a BIG difference if the wrong type is used.
I would bet that may be the problem. Clean out the bearing and try a automotive oil like a "0W20"
Take the belt off and spin the platter with your fingers. Watch it as it slows down.
If with no belt, and light oil in the bearing, it stops in the same (or nearly the same place mark a spot on rim of platter and watch it many times as to if it stops in the same general location) Then it has a problem in the shaft of the bearing. If not... and with light oil the platter being run by the motor still has the problem.. ??????
Most TT motors rely on the A/C 60 hz cycle to rotate evenly, but something may be wrong in there, if it is not the bearing or grease.
Many small devices are sold which are motor controls that hold the speed steady. If you could borrow one to see if that is the problem?
