(6) Support the propeller assembly with a sling.
NOTE 1: Supporting the propeller with a sling can be
delayed until all but two mounting bolts and
washers have been removed to permit rotating
the propeller for ease of bolt removal.
NOTE 2: If the propeller will be reinstalled and it has
been dynamically balanced, make an
identifying mark on the propeller hub and a
matching mark on the engine flange to make
sure of proper orientation during re-installation
to prevent dynamic imbalance.
CAUTION:
DISCARD THE PROPELLER MOUNTING
BOLTS IF THEY ARE DAMAGED OR
CORRODED, OR WHEN THE PROPELLER
IS REMOVED FOR OVERHAUL.
(7) Remove the propeller mounting bolts and washers.
NOTE: If the propeller is removed between overhaul
intervals, mounting bolts and washers may be
reused if they are not damaged or corroded.
CAUTION:
USE ADEQUATE PRECAUTIONS TO
PROTECT THE PROPELLER ASSEMBLY
FROM DAMAGE WHEN IT IS REMOVED
FROM THE AIRCRAFT ENGINE AND
WHEN IT IS STORED.
(8) Using the support sling, lift the propeller from the
mounting flange.
(9) Remove and discard propeller mounting O-ring.
(10) Install suitable covers on the pitch change rod opening,
propeller mounting flange, and engine flange to prevent
the introduction of contamination.
(11) Put the propeller on a suitable cart for transportation.
