the propeller assembly to the aircraft engine shaft.

ESTABLISHED DURING BENCH
ASSEMBLY AND ADJUSTMENT.

and, at the same time, rotate the blades to high pitch
until the push rods that protrude from the jack plate
unit stop short of the two bushing lugs on the hub.
(u) Rotate the jack plate unit to allow each fork to engage
each pitch change block and to align each push rod
with each hub bushing.
(v) Grip the blade counterweight on each blade clamp,
and at the same time, rotate both blades to low pitch
by hand.
(w) Rotate the blades to install the push rods through the
hub bushings.
