Remove the hex wrench again and spin the swashplate. It should spin very smoothly,
BUT HAVE LITTLE OR NO NOTICEABLE VERTICAL PLAY
. If the races bind or turn
roughly, remove the locking bolt, reinsert the wrench and unscrew the races to the next
set of locking holes. Replace the bolt and universal ball, and check the motion of the
swashplate again. If the swashplate still does not move freely, disassemble and check
for dirt or other foreign matter in the grease, and repeat the last two steps.

q
Once the swashplate spins smoothly, slip metal universal balls onto two more 2-56 x 3/8"
bolts, apply threadlock to the bolt threads, and screw the bolts into the swashplate as you
did with the first bolt. Remove the first bolt, apply threadlock to the threads and screw it
back into the swashplate. Tighten all bolts (but be careful not to strip the threads).

q
Screw two plastic ball-links onto two threaded L-links, and adjust to the length shown in
Fig. 8-3.

q
Attach the fore/aft control arm to the upper bearing block (which is mounted to the crutch)
with a 4-40 x 3/8" bolt and washer. To avoid stripping the hole, push the bolt into the hole
while turning it, and do not over-tighten it. The fore/aft control arm should move freely.
Insert the free end of each L-link into the control arm as shown.
