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.

Again, thanks for the responses. The Heybrook bearing appears to be similar to the Lynn. I'll be tinkering with it the next couple of nights, hopefully spinning vinyl this weekend. Cheers.
What symptoms will the tt show if the oil around the main bearing is old or smutty? Rumble?

I can't speak for that specific table but when I finally replaced the bearing oil in my VPI after too many years, the platter stopped after one-and-a-half turns instead of one-half a turn.   The motor probably runs cooler now.  There was a little wear on the bearing.  Maybe a little higher noise floor.  I didn't notice any rumble.
