Clearaudio CMB CERAMIC-MAGNETIC-BEARING - Handbuch (Seite 6)

The CMB-bearing consists out of two parts, one upper bearing
part and one lower bearing part.
A magnetic ring is placed on each bearing part and is
additionally marked with a colour-coding.
When leaving the factory the CMB-bearing is greased with full-
synthetic oil (Art. No.: AC068).
To assure the best greasing of your CMB-Bearing, we
recommend to put a few drops of the full-synthetic oil onto the
ceramic-axis every 12 months.
Assembly:
The assembly of the CMB-bearing is very easy and is done in a
moment:
Therefore take the turntable platter of the turntable-bearing
and place it apart.
Use an hex key wrench that fits to unscrew the screw at the
upper side of your turntable.
Take the bearing out of the cut-out in the chassis and lay it
apart.
Clean the cut-out in the chassis with an adequate cleaning fluid.
Now place the CMB-bearing into the cut-out of the chassis and
be sure that the colour coding of both magnetic rings are facing
each other.
Mount the CMB-bearing into the cut-out using the screw of your
exchanged bearing.
At this moment don´t forget to place the metal disc between
the chassis and the screw.
Slide the turntable platter gently (!) onto the upper part of the
bearing. Do not use to much pressure!
Do not try to slide the CMB-Bearing and the turntable platter
together onto the ceramic axis, damage could occur!
