PROPELLER ASSEMBLY.
REMOVAL OF PROPELLER.
1. Insure master and magneto switches are off.
2. Move fuel selector to off position.
3. Place mixture control in idle cut-off.
Before removing spinner components, reference each mating
part to facilitate in alignment for reassembly.
4. Remove spinner by removing attaching screws.
5. Remove propeller assembly by the following procedure:
A. Support propeller assembly with appropriate sling and hoist.
B. Place drip pan under the propeller to catch oil spillage.
C. Remove safety wire from propeller mounting nuts. Loosen the nuts about 1/4 inch and pull propeller
assembly forward against the nuts to allow oil to drain from the propeller and engine cavities.
Nuts with studs will have to be backed out evenly so that propeller
may be pulled forward (approximately 1/4 inch at a time) until all
studs are disengaged from the engine crankshaft flange.
D. Cap engine flange to prevent contamination.
CLEANING, INSPECTION AND REPAIR OF PROPELLER.
1. Check for oil leaks.
2. Clean spinner and propeller assembly with a non-corrosive solvent.
3. Inspect spinner and propeller hub components for cracks.
4. Check all visible components for wear and safety.
5. Inspect blades for nicks and cracks. Refer to Figure 61-6 for propeller blade minor repair. Nicks in
leading edges of blades should be filed out and all edges rounded, as cracks sometimes start from such places.
Use fine emery cloth for finishing.
6. Hartzell propellers require grease to the blade hub through zerk fittings. Remove one of the two
fittings for each propeller blade, alternate the next time. Apply grease through the zerk fitting until fresh grease
appears at the fitting hole of the removed fitting. This care should be taken to avoid blowing out hub gaskets.
7. Check for freedom of blade movement in propeller hub by rocking each blade back and forth through
the slight movement allowed by the pitch change mechanism. Blades that will not allow this movement
indicate internal damage.
8. If internal or major external damage is apparent, the propeller assembly should be referred to an
appropriate repair facility.
9. Check condition of propeller mounting nuts on studs.
