(m) Install one reverse stop (Table 3-1) on each sleeve and
push rod against the sleeve shoulder.
(n) Clean the engine shaft with an approved solvent.
(o) Oil the engine shaft with engine oil.
(p) Install the engine shaft spacer(s) and rear cone
(Table 3-1).
NOTE: Install the same number of spacers as
previously installed, if the same propeller is
reinstalled. If a different propeller is installed,
install one spacer. The need for additional
spacers will be determined during static
RPM checks, after the propeller is installed.
WARNING: MAKE SURE THE SLING IS SUITABLY
RATED TO SUPPORT THE WEIGHT OF
THE PROPELLER ASSEMBLY DURING
INSTALLATION.
(q) With a suitable crane hoist and sling, carefully move
the propeller assembly to the aircraft engine shaft.
(r) Install the propeller hub on the engine shaft.
CAUTION 1: USE THE MARKINGS MADE DURING
BENCH ASSEMBLY TO MATCH THE
FORKS, BLOCKS, AND LINKSCREWS
THAT WERE PREVIOUSLY MATED.
CAUTION 2: MAINTAIN THE SAME BLOCK
ORIENTATION THAT WAS
ESTABLISHED DURING BENCH
ASSEMBLY AND ADJUSTMENT.
(s) Install a pitch change block on each clamp link screw.
(t) Grip the blade counterweight on each blade clamp,
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 three bushings in the guide collar
near the hub nut.
(u) Rotate the jack plate unit to allow each fork to engage
each pitch change block and to align each push rod
with each guide collar bushing.
