Apply a 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 8 of
Appendix 1 ) into the
channel formed between the outer perimeter of the
stationary base and the inner perimeter of the revolving
turret (see
Figure 28 ). 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 Perimeter Bearing Balls
Use tweezers to carefully set the 3/32” bearing balls
(there are 80 of them) into the grease ring (see Figure
29 ), placing the bearing balls as close together as
possible as you proceed.

Reinstall the Threaded Retaining Ring
Carefully engage the threads of the threaded retaining
ring with the threads in the revolving turret (see

Or use a center punch or nailset tool to snug the threaded retaining ring by
placing the tip of the tool into one of the four tooling holes and lightly
tapping the tool with a small hammer or mallet to drive the threaded
retaining ring clockwise.
