(3) New or newly overhauled propellers should be lubricated
after the first one or two hours of operation because
centrifugal loads will pack and redistribute grease, which
can result in a propeller imbalance. Redistribution of
grease may also result in voids in the blade bearing area
where moisture can collect.
(a) Purchasers of new aircraft should check the
propeller logbook to verify whether the propeller was
lubricated by the manufacturer during flight testing.
If it was not lubricated, the propeller should be
serviced at the earliest convenience.
B. Lubrication Procedure
WARNING 1: FOLLOW LUBRICATION PROCEDURES
CORRECTLY TO MAINTAIN 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.
(2) Each blade socket has two lubrication fittings
or one
lubrication fitting and one lubrication plug.
Refer to Figure 6-1.
(3) Remove the c
aps from the lubrication fittings.
(4) Remove the lubrication fittings
or the 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) from
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) from the ENGINE-SIDE hub half.
