WARNING
:
MAKE SURE THE SLING IS RATED UP TO
800 POUNDS (363 KG.) TO SUPPORT THE
WEIGHT OF THE PROPELLER ASSEMBLY
DURING REMOVAL.
(4) Support the propeller assembly with a sling.
NOTE 1
: To permit rotation of the propeller for ease of
bolt removal, supporting the propeller with a
sling may be delayed until all but two mounting
bolts and washers have been removed.
NOTE 2
: If the propeller will be reinstalled, and it
has been dynamically balanced, make
an identifying mark (with a felt-tipped pen
only) on the propeller hub and a matching
mark on the engine flange to make sure of
proper positioning of the propeller during
reinstallation. This will prevent dynamic
imbalance.
(5) Record the position of each start lock in relation to its
matching blade.
(6) Remove the start lock brackets to access the mounting
bolts.
NOTE
: It is not necessary to remove the wire that is
holding the stop pin in place.
(7) Cut and remove the safety wire from the propeller
mounting bolts.
CAUTION
:
DISCARD THE PROPELLER MOUNTING
BOLTS AND WASHERS IF THEY ARE
DAMAGED OR CORRODED, OR IF
THE PROPELLER IS REMOVED FOR
OVERHAUL.
(8) Remove the propeller mounting bolts from the engine
flange.
