PROPELLER INSTALLATION
1. Perform the appropriate steps provided in Spinner
Bulkhead to Propeller Hub installation.
2. Clean the engine flange and propeller flange with
Quick Dry Stoddard Solvent or MEK.
3. Install the O--ring in the O--ring groove in the hub
bore
-- WARNING --
Make sure the sling is rated up to 800 Lbs. (363
KG) to support the weight of the propeller assem-
bly during installation.
4. With a suitable crane hoist and sling, carefully
move the propeller assembly to the aircraft engine
mounting flange in preparation for installation.
NOTE:
If the propeller is equipped with an anti--ice or a
de--ice system, follow the applicable manufactur-
er’s instructions for installation of the anti--ice or
de--ice system hardware.
5. Install the propeller on the engine flange. Make
certain to align the dowel pins in the propeller flange
with the corresponding holes in the engine mounting
flange.
-- CAUTION --
Mounting hardware must be clean and dry to pre-
vent excessive preload of the mounting flange.
-- CAUTION --
Tighten nuts evenly to avoid hub damage.
6. Torque the 1/2 inch propeller mounting lock nuts
(dry) as indicated in Torque Table (Figure 61--4).
NOTE:
Safety wire is not required (by Hartzell) in the
mounting studs
7. Install the propeller spinner dome in accordance
with Spinner Installation.
SPINNER INSTALLATION
-- CAUTION --
To prevent damage to the blade and blade paint,
wrap the blade shanks in several layers of mask-
ing or duct tape before installing the spinner
dome. Remove tape after the spinner is installed.
1. Examine the interior of the spinner dome. The
spinner dome has an internal support (Figure 61--1)
that encircles the propeller cylinder. The cylinder may
need to be wrapped with one or more layers of abrasion
and wear resistant UHMW tape (Hartzell P/N
B--6654--100).
NOTE:
The UHMW tape on the cylinder should be
checked for smoothness of tape layers and that
spinner dome internal support fits snug against
cylinder. Spinner dome internal support must fit
snugly on cylinder, or cylinder will become dam-
aged by chafing.
2. Install the spinner and check for a snug fit where
the internal support contacts the cylinder. If the support
does not fit snugly on the cylinder, apply a layer of tape
and recheck. Repeat until the spinner support fits snug-
ly on the cylinder.
NOTE:
When the spinner dome has been removed to
facilitate maintenance, check the spinner internal
support to cylinder fit. If the spinner loosens in
service, add one or more layers of UHMW tape to
the cylinder until the spinner fits snugly.
3. Secure the spinner to the spinner bulkhead or
adapter ring with the supplied screws and washers. To
avoid damaging the aircraft cowling, screws must not
extend more than three threads past the bulkhead nut-
plates.
61--10--00 -- PROPELLER ASSEMBLY
Preflight inspection should be accomplished prior to
each flight to determine: if blades have been damaged,
if any abnormal looseness is evident between hub and
blades or if there is any evidence of oil leakage. Propel-
ler must be repaired if any of above is evident.
The propeller is to be lubricated at intervals not to ex-
ceed 100 hours or at 12 calendar months, whichever
occurs first.
If annual operation is significantly less than 100 hours,
calendar lubrication intervals should be reduced to six
months.
If the aircraft is operated or stored under adverse atmo-
spheric conditions, e.g., high humidity, salt air, calendar
lubrication intervals should be reduced to six months.
Owners of high use aircraft may extend their lubrication
interval. Lubrication interval may be gradually ex-
tended after evaluation of previous propeller overhauls
with regard to bearing wear and internal corrosion.
NOTE:
Hartzell recommends that new or newly over-
hauled propellers be lubricated after the first one
or two hours of operation because centrifugal
loads will pack and redistribute grease, which
may result in a propeller imbalance. Redistribu-
tion of grease may also result in voids in the
blade bearing area where moisture can collect.
LUBRICATION PROCEDURE
-- CAUTION --
Follow lubrication procedures correctly to main-
tain an accurate balance of the propeller
assembly.
1. Remove the propeller spinner.
2. Each blade socket has two (front and rear) lubrica-
tion fittings. Remove the lubrication fitting caps from
both sides of the hub assembly. Remove the lubrication
fittings from either the cylinder side or the engine side of
the hub assembly. It is preferable to apply grease to the
fitting located nearest the leading edge of the blade.
Greasing at this location reduces the possibility of
grease bypassing the bearing area and entering the
hub cavity.
