If equipped with a shrink rod, disconnect the shrink rod from the strut, not from the aircraft. This is accomplished by removing the rod fitting bolt at the bottom of the rod. When the shrink rod is disconnected, the nut and bolt should be reinstalled in the fitting for safekeeping. Support the recoil strut and partially pull the crossbolt at the top of the strut to disengage it from the support structure. Lower the strut and reinstall the bolt and nut.
Installation essentially reverses the removal procedures.
With the aircraft still on jacks, carefully move the top of the recoil strut into place to engage the support structure fitting. Install the crossbolt, washer, nut, and cotter pin. Connect the shrink rod to the shrink rod fitting. Connect the side brace to the support structure fitting. Partially pull the upper torque arm pin and connect the drag brace.
