start lock pins and hold them in place with a heavy
wire inserted through the hole of each start lock
housing.
(b) Carefully push the piston toward the engine,
rotating the blades to feather position, and attach
the piston nut to the pitch change rod.

to hold the pitch change rod.

wrench, torque the piston nut. Refer to Table 3-2
and Figure 3-4 for the proper torque value.
