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.
