a. If the landing gear handle shaft (1) or gear (2) was removed, the parts must be indexed and
assembled as shown in Figure 6-13.
b.
Lubricate the shaft (1), install the cam (3) and spacer (4) on the shaft and insert the shaft into
the Power Pack.
c. Install the return cam (5) with the roll pin (6). Both sides of the cam surfaces are identical. Check

shaft. If shaft binds, remove the cam and lap inside boss of cam to obtain slight endplay in the shaft with
the cam installed.

for freedom of movement.
e. Install the Power Pack control arm on the end of the shaft with the arm pointing down. Align the
holes between the shaft and the arm assembly and install the roll pin. Install .040 safety wire through the
roll pin and around half of the arm. Roll the twisted end of the safety wire around the other half of the arm
assembly. (Refer to Figure 8-14.)
