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 lower the stationary base into
the recess of the revolving turret (see
Figure 23 – Reinstall stationary base into revolving turret
Apply Ring of Grease for the Perimeter Balls
The next step is to apply grease into the ring in which
the perimeter bearing balls will be placed. Carefully
apply a ring of grease (item S2 of
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 Threaded Retaining Ring
Carefully engage the threads of the threaded retaining
ring with the threads in the revolving turret (see
