Complete Teardown, Cleaning, and Reassembly of the Olympus BH2-6RE Modular Revolving Nosepiece Page 11 of 18
Revision 3
Clean Grease from 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 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 23 ).

Apply Ring of Grease for the Perimeter Balls
The next step is to apply grease into the ring into which
the perimeter bearing balls will be placed. Carefully
apply a ring of grease (item S2 of
Appendix 1 ) into the
channel formed between the outer perimeter of the
stationary base and the inner perimeter of the revolving
turret (see
Figure 24 ). Do not apply too much grease
here, to minimize the squeeze-out that will occur when
the threaded retaining ring is reinstalled to hold the
stationary base into the recess of the revolving turret.

Reinstall the Perimeter Bearing Balls
Use tweezers to carefully set the 3/32” bearing balls
(there are 83 of them) into the grease ring (see Figure
25 ), placing the bearing balls as close together as
possible as you proceed.

Reinstall the Threaded Retaining Ring
Carefully engage the threads of the threaded retaining
ring with the threads in the revolving turret (see
Figure
26 ).
Figure 26 – Engage the threaded retaining ring
Use a suitable lens spanner tool (item T3 of Appendix 1 )
in a pair of opposing tooling holes to tighten the
threaded retaining ring

(see Figure 27 ).

tip of the tool into one of the four tooling holes and lightly tapping the tool with a small
hammer or mallet to drive the threaded retaining ring clockwise.
