Capstan Kit; Aircraft Specific Mounting Kits - Garmin G3X Installation Manual

9.5.2.8 Capstan Kit

The 011-02952-02 is the capstan kit. This kit contains a capstan, a cable guard, and fasteners used to
attach these items. The capstan was designed to accept a MS20663C2 double shank ball with a 1/16"
diameter cable. This kit does not currently include a bridle cable or cable clamps necessary to link the
capstan to the flight control cables. Contact Garmin if these items are needed for your application.
The 011-02952-02 capstan kit is provided with four #4-40 screws and lock washers for attaching the cable
guard. The screws provided are 0.25" long. This length of screw is appropriate if there is no bracket or
spacers in-between the cable guard and servo. If a mounting bracket or spacers of thickness .056" or
greater will be place in-between the stop bracket and servo, longer screws should be used to attach the
cable guard. It is recommended the thread engagement into the GSA 28, as measured from the front face
of the servo shall be 0.112" – 0.25". If screws other than what is provided will be used, be sure to use
thread locking compound or a proper thread locking patch combined with the lock washers provided. Also
be sure to follow the recommended tightening torque specified in
CAUTION
If screws are being used to mount the cable guard to the front face of the GSA 28
are different than the screws provided with the stop bracket kit, care must be
taken to ensure these screws are not long enough to contact moving parts inside
the GSA 28. Maximum screw insertion, as measured from the front of the GSA
28, must be less than 0.25" to avoid contact with parts inside the GSA 28.

9.5.2.9 Aircraft Specific Mounting Kits

GSA 28 mounting kits are available for several experimental airframes. These mounting kits are listed in
Table 9-8. All of these kits contain sheet metal mounting brackets and push rods that have been designed
for the specific application. The push rods are supplied cut to the appropriate length and tapped for the
male rod end bearings provided. Overall push rod length as well as rod end bearing thread engagement
length is provided on the drawings for each kit. The lengths specified are considered nominal. This length
should be adjusted to fit the specific application. Ideal push rod length results in the push rod being
perpendicular to the servo arm when it is at the center of travel.
It is recommended the stop bracket is installed with all push/pull applications. The drawings for each of
these mounting kits shows the recommended orientation of this bracket. It is acceptable to deviate from
these drawings if a better orientation has been determined by the installer. The best orientation results in
the stop bracket flanges being equal distance from the servo arm when at the center of travel. See
9.5.2.2 on stop bracket kit for more details on mounting the stop bracket.
