B. Lubrication Procedure
WARNING 1: FOLLOW LUBRICATION PROCEDURES
CORRECTLY TO MAINTAIN AN
ACCURATE BALANCE OF THE
PROPELLER ASSEMBLY.
WARNING 2: PITCH CONTROL DIFFICULTY COULD
RESULT IF THE PROPELLER IS NOT
CORRECTLY LUBRICATED.
(1) Remove the propeller spinner dome.
(2) Refer to Figure 6-1 and Figure 6-2. Each blade socket has
two lubrication fittings or one lubrication fitting and one
lubrication hole plug.
(3)
Remove the lubrication fitting caps from the
lubrication
fittings.
(4)
Remove the lubrication fittings
or the lubrication hole
plugs, as applicable.
(a) For all tractor or pusher propellers with clockwise
(standard) rotation when viewed from BEHIND the
aircraft, remove the lubrication fittings P/N A-279 or
C-6349 or lubrication hole plugs P/N 106545 in the
CYLINDER-SIDE hub half.
(b) For all tractor or pusher propellers with counter-
clockwise (backward) rotation when viewed from
BEHIND the aircraft, remove the lubrication fittings
P/N A-279 or C-6349 or lubrication hole plugs
P/N 106545 in the ENGINE-SIDE hub half.
(c) Some propellers use an internal blade seal that
prevents grease from entering the hub cavity.
Because this seal is very efficient, it is important to
remove the opposite lubrication fitting. Pitch control
difficulty could result if the propeller is not correctly
lubricated.
(5) Using a piece of safety wire, loosen any blockage or
hardened grease at the threaded holes where the
lubrication fitting
or lubrication hole plug was removed.
