Once the slotted lock ring has been loosened, remove
the screwdriver handle from the bores in the revolving
turret and the stationary base (which is locking the

Figure 17 – 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
18). Be careful and do not accidentally put
the center punch or nailset tool into one of the four
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.
