PROPELLER MAINTENANCE
PROPELLER REMOVAL
A. Remove the forward cowl from the engine.
B. Remove the spinner dome by removing the attaching screws from around the rear
circumference.
C. Disconnect the front fork-end from the propeller-reversing lever. Disconnect the pivot bolt
securing the reversing lever to the propeller governor actuating lever and lift the reversing
lever free of the collar prior to pulling the low pitch stop collar fully forward.
** CAUTION **
The procedures in the step above must be accomplished to
avoid damaging the propeller governor.
D. Install the feedback ring-puller and pull the low pitch stop collar fully forward.
** CAUTION **
Make sure that the tool is not cocked to avoid damaging the
propeller. Take the precautions necessary to avoid bending or
otherwise damaging the three spring-loaded rods and the beta
feedback ring.
* NOTE *
Mark propeller hub flange and the engine shaft flange so that
the propeller can be reinstalled in its original position. This will
prevent disturbing the propeller/engine combination dynamic
balancing if the same propeller is to be reinstalled.
E. Remove the safety wire from the propeller mounting bolts. Using a 5/8" box head wrench,
remove the eight or twelve bolts securing the propeller in place and remove the propeller
from the airplane.
