Remove the Threaded Retaining Ring
The stationary base is held inside the recess of the
revolving turret by the threaded retaining ring (see
Figure
18).
Figure 18 – Components of the turret assembly
Place the turret assembly into a suitable work vise and
use a heat gun to thoroughly heat the turret assembly,
to soften the internal grease. Then use a center punch
or nailset tool to loosen the threaded retaining ring by
placing the tip of the tool into one of the four tooling
holes in the threaded retaining ring (see
driving the threaded retaining ring counter-clockwise by
carefully tapping the tool with a small hammer or mallet
(see
Figure
19). Be careful and do not accidentally put
the center punch or nailset tool into one of the six
detent notches in the revolving turret (instead of into
one of the four tooling holes in the threaded retaining
ring), or the revolving turret will be irreparably
damaged when the punch is struck by the mallet.
Figure 19 – Loosen the threaded retaining ring
Continue loosening the threaded retaining ring and
remove it, being careful that the perimeter bearing balls
beneath the threaded retaining ring do not fall out and
become lost in the process (see
Complete Teardown, Cleaning, and Reassembly of the Olympus BH2-6RE Modular Revolving Nosepiece
Figure
18) and
Figure
20).

Remove the Perimeter Bearing Balls
Carefully remove the 3/32" bearing balls (there are 83
of them) from the perimeter of the stationary base. A
small magnet can come in handy here (see
Figure 21 – Remove the perimeter bearing balls
Remove the Stationary Base from the Turret
Once the perimeter bearing balls have been removed,
lift the stationary base free of the recess in the
revolving turret and remove it (see
Figure 22 – Lift and remove the stationary base
