How much bearing oil?

As a person trained in Linn turntable setup, I agree with Lugnut's advice. However, when inserting the spindle/platter assembly into the bearing, be careful to not ding the top edge of the bearing with the spindle, center it carefully. Let the platter's own weight settle it down into the bearing as far as it wants to go on its own. Then spin the platter to cause it to settle in the rest of the way. This ensures a good distribution of the oil around the spindle as it settles and helps any trapped air bubbles to escape. Also, it goes without saying that the spindle must be perfectly clean before inserting. Good luck!

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.
