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.
CAUTION:
(6) Remove the propeller mounting bolts and washers.
If the propeller is removed between overhaul
NOTE:
intervals, mounting bolts and washers may be
reused if they are not damaged or corroded.
CAUTION:
(7) Using the support sling, lift the propeller from the
mounting flange.
(8) Remove and discard propeller mounting O-ring.
