INSTALLATION AND REMOVAL
Propeller Owner's Manual
175
This will make sure that the components
are reassembled in their original location.
MAKE SURE THE SLING IS RATED UP TO
800 POUNDS (363 KG) TO SUPPORT THE
WEIGHT OF THE PROPELLER ASSEMBLY
DURING REMOVAL.
Because the shaft nut is pulling the propeller
hub off the tapered rear cone, there will be
significant resistance to the loosening of the
shaft nut.
