o. Remove -5 rig pin installed in step g. Move
pilot cyclic stick left until it contacts stop.
Position rigging fixture to lateral LEFT
pointer next to right lateral bellcrank link bolt
(fig. 11–89). Verify that center of the lateral
bellcrank link bolt is between the MAX and
MIN marks on rigging fixture lateral LEFT
pointer (fig. 11–91).
If center of lateral link bolt nut does not lie between
MAX and MIN marks, rig pilot and CPG lateral cyclic
stick stops (TM 1-1520-238-23).
If lateral cyclic stick stops are rigged correctly, replace
lateral servocylinder (TM 1-1520-238-23).
p. Move pilot cyclic stick right until it contacts
stop. Position rigging fixture to place lateral
RIGHT pointer next to right lateral bellcrank
link bolt. Verify that center of the lateral
bellcrank link bolt is between the MAX and
MIN marks on rigging fixture lateral RIGHT
pointer (fig. 11–92).
If center of lateral link bolt nut does not lie between
MAX and MIN marks, rig pilot and CPG lateral cyclic
stick stops (TM 1-1520-238-23).
If lateral cyclic stick stops are rigged correctly, replace
lateral servocylinder (TM 1-1520-238-23).
