15.5.2.7 Generic Push/Pull Kits
The 011-02952-00 and -01 kits are generic kits for push/pull applications. This kit is supplied with a 3/8"
diameter x 8" long solid rod (Figure 15-4). This rod is intended to be used as the attachment link between
the GSA 28 and the flight control system. It is the installer's responsibility to cut this rod to the correct
length and tap the ends for the male rod end bearings. It is recommended these push rods are tapped to a
depth of at least 0.61" to accommodate the entire thread of the rod end bearing (minus the jam nut). The
length of the push rod is adjustable by changing the thread engagement between the male rod end bearings
and push rod. The acceptable range of thread engagement is 0.492" +/-0.117". It is highly recommended
the AN315-3R jam nuts are used and properly tightened. A push rod without a tightened jam nut will
create backlash that can diminish autopilot performance.
WARNING
Thread engagement between the male rod end bearings supplied with GSA 28 mounting kits
and push rod must not be less than 0.375". This minimum engagement length is
recommended to prevent push rod from coming apart.
