POWER PLANT.
Regularly check the engine compartment for oil and fuel leaks, chafing of lines, loose wires and tightness
of all parts. Maintenance instructions for the power plant may be found in Chapter 71 of this manual and in the
appropriate manufacturer's manuals.
PROPELLER.
The spinner, back plate and propeller surfaces should be cleaned and inspected frequently for nicks,
scratches, corrosion and cracks. Minor nicks and scratches may be removed as found in Chapter 61. The face
of each blade should be painted when necessary with a flat paint to retard glare. To prevent corrosion, wipe
surfaces with a light oil or wax.
In addition, propellers should be inspected for grease or oil leakage and freedom of rotation on the hub
pilot tube. To check freedom of rotation, rock the blade back and forth through the slight freedom allowed by
the pitch change mechanism. Lubricate the propeller at 100-hour intervals in accordance with the Lubrication
Chart.
Additional service information for the propeller may be found in Chapter 61.
CLEANING.
ENGINE COMPARTMENT.
Before cleaning the engine compartment, place a strip of tape on the magneto vents to prevent any solvent
from entering these units.
1. Place a pan under the engine to catch waste.
2. With the engine cowling removed, spray or brush the engine with solvent or a mixture of solvent and
d e g r e a s e r, as desired. It may be necessary to brush areas that were sprayed where heavy grease and dirt
deposits have collected in order to clean them.
Do not spray solvent into the alternator, starter, air intake, and
alternate air inlets.
3. Allow the solvent to remain on the engine from five to ten minutes, then rinse the engine clean with
additional solvent and allow to dry.
Do not operate engine until excess solvent has evaporated or
other wise been removed.
4. Remove the protective covers from the magnetos.
5. Lubricate controls, bearing surfaces, etc., per Lubrication Chart.
