Kim, what I
would recommend if to keep presuming that the air pump do not supply enough air
flow. We understand that your platter does nor rise high enough and does not
clear the glass plates. The only reasons for it would be the air pressure is
not sufficient enough for the air discharge you have. So, let (juts for sake of
experiment) to increase the air flow unit the plate rise enough to clear the
have two possibilities. If you pumping more and more air flow get the state
that your platter get a free spinning then you might have a defective pump or
air leak. BTW, if everything works fine then this TT needs a remarkably low air
flow, you shall hardly feel the flow in the hose but even this shall make the
platter rise. I use $20 aquarium air pumps and they do very fine.
second opposability is a bit uglier and I personally feel that is it what you
have. If you pump a lot of air and your platter do not rise then you have
something that prevent yours platter to rise. The scratches on the glasses that you report is an indication of dirt
that one was between the glass surfaces, so I wonder if that dirt that was
there made somewhere that juts blocks the platter free vertical movement? I would
serially to investigate this direction.
Regarding the bearing. The bearing in this TT is
VERY simple. You need to flip TT and to unscrew a back plate with 6 or 8 screws.
The bearing will fall out on the table. The bearing on this TT is not what you
think. The 1500-5000 models have a ball under the main shaft that is rolling on
the back plate that you just unscrewed. In these TTs you need to lubricate all
of it but not in 8000. In the 8000 the rising palter shall decuple the bearing
from contact and most of the 8000 do not even have the ball under the shaft.
What the 8000 do have is the long cylindrical friction shaft that is very tightly
sits in the TT base and into which the palter’s main shaft is inserted. You do
want to remove this shaft and lubricate it. I think W40 will do. Make sure that
it is absolutely clean and that the female part of the shaft (the indentation
on the base) is very clean and lubricated. I presume that it is very dry and dirty
and this is something that preclude the platter to rise.
As you clear it I would also buff the glass
platform, making sure that scratches borders do not rise over the glass
