Reinstall the Slotted Lock Ring
Carefully engage the threads of the slotted lock ring
with the pivot-adjustment screw (see
Figure 37

Reinstall the slotted lock ring
Spin the revolving turret until one of the five threaded
objective bores in the revolving turret aligns with the
bore in the stationary base. Insert a suitably sized
screwdriver handle into these bores to lock the
revolving turret to the stationary base. Use a suitable
tool (see
) to snug the slotted lock ring down
to lock the pivot-adjustment screw in place (see
). Do not allow the pivot-adjustment screw to rotate
while tightening the slotted lock ring.

Verify the Feel of the Revolving Nosepiece
Hold the turret assembly by gripping the stationary base
in one hand and spin the revolving turret with the other
hand. The motion of the turret should not feel gritty,
erratic, or excessively stiff. If it does, loosen the slotted
lock ring, readjust the pivot-adjustment screw, and
retighten the slotted lock ring (as described above) until
the turret motion feels acceptable.
Clean Off Any Visible Grease
Use a suitable solvent (e.g., mineral spirits) and a clean
rag or tissue to thoroughly clean any visible grease from
the exterior of the turret assembly. Be careful while
removing the excess grease, to prevent any of the
solvent from dripping into the revolving turret
mechanism and fouling the grease within.
Reinstall the Mechanical Detent Stop
Place the mechanical detent stop in position on the
stationary base, aligning the two holes in the
mechanical detent stop with the tapped holes in the
stationary base (see
). Make sure the stop ball
on the mechanical detent stop is facing downwards (see
).

Use a suitable JIS screwdriver to reinstall two M2X4
pan-head screws to secure the mechanical detent stop
into place (see
