INSTALLATION AND REMOVAL
Propeller Owner's Manual
140
To obtain the proper dimension, remove the
link, grip the small end in a vise, and bend it
until the distance between the two holes on
the link has changed the required amount to
obtain 1.31 inches (33.3 mm) on the spool
length.
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
the static RPM checks after the propeller is
installed.
USE A SUITABLY RATED SLING TO
SUPPORT THE WEIGHT OF THE
PROPELLER ASSEMBLY DURING
INSTALLATION.
