If the assembly is similiar to a Linn then put about 3/4 bottle of oil into the bearing, pack tissue or paper towel around the bearing and insert the sub-platter. The excess oil will flow onto the absorbant material. If there wasn't any overflow add more oil until there is some excess. Carefully clean up any mess without contaminating the bearing oil. Needless to say, the sub-platter needs to be gently pushed down into the bearing assembly. Otherwise, when the weight of the platter is added more oil will seep out and may make a mess.
How much bearing oil?
I aquired a Heybrook TT2, 1980 vintage. It is basically a poor mans LP12. Because of it's age, I cleaned out the old bearing oil. I did this before realizing I did not have the original measuring syringe for injecting the bearing oil. I have a small bottle of new JA Mitchell synthetic bearing oil. Does anyone have an idea of how much I should use? The quantity in the bottle is tiny, but appears to be too much. Any suggestions would be greatly appreciated.
