in the center groove. Set the cable swage into the hole in the pulley and pass the other end of the
bridle cable under the opposite flange. Feed both cable ends around the pulley and underneath the
next set of cable guard flanges following the grooves.
With the cable properly fed into the pulley, install the servo in the mount. Rotate the capstan until
the installed swage sits on the opposite side of the pulley from where the bridle cable exits the servo
(see figure 1). Set the control stick to neutral and then install the cable clamps using the provided
AN3H-6A bolts, AN970-3 washers, and AN365-1032A lock nuts (see figure 2). The grooves in the
cable clamps are designed to work with the provided bridle cable diameter of 1/16” (small groove)
and aircraft control cable diameter of 1/8” (large grooves). The bridle cable should be taught and
have approximately 1” of cable protruding from the ends of the clamps. Torque them to 35 in-lbs to
provide the appropriate clamp force on the cables.
