Complete Teardown, Cleaning, and Reassembly of the Olympus BHSU/BHTU Reverse Nosepiece Assembly Revision 3 Page 11 of 19
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
Figure 22 ) and
driving the threaded retaining ring counter-clockwise by
carefully tapping the tool with a small hammer or mallet
(see
Figure 23 ). Be careful and do not accidentally put
the center punch or nailset tool into one of the five
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 23 – 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
Figure 24 ).

Remove the Perimeter Bearing Balls
Carefully remove the 3/32” bearing balls (there are 8 0
of them) from the channel formed by the outer
perimeter of the stationary base and the inner
perimeter of the revolving turret. A small magnet can
come in handy here (see
Figure 25 ).

Remove the Stationary Base from the Turret
Once the perimeter bearing balls have been removed
from the channel, lift the stationary base free of the
recess in the revolving turret and remove it (see
Figure
26 ).

Thoroughly Clean the Various Components
Use a suitable solvent (e.g., acetone) to thoroughly
clean all the old grease from the stationary base,
revolving turret, threaded retaining ring, perimeter
bearing balls, center-pivot ball, mechanical detent stop,
pivot-adjustment screw, and the slotted lock ring, in
preparation for reassembly.
Reinstall Stationary Base into the Revolving Turret
Hold the stationary base such that the center pivot is
facing downwards, and then lower the stationary base
into the recess of the revolving turret (see
Figure 27 ).
