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
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.

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
