brace, reinstall the pin and nut to retain the torque arm.
The side brace is generally removed with the strut
assembly. It should be disconnected at its upper end by
removing the nut and pin. After the side brace is
disconnected, reinstall the pin.
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.
CAUTION
Before removing a wheel assembly from an
aircraft deflate the tire completely. To ensure
positive removal of all pressure from the tire
you should remove the valve core and attach
a deflated tire tag to the valve stem after
deflating the tire.
