Piper Dakota - Application of Grease 1 D10; Application of Oil 1 D10; Lubrication Chart 1 D10

APPLICATION OF OIL
Observe the following precautions whenever specific instructions for lubrication of mechanisms is not
available:
l. Apply oil sparingly. Do not use more than required to coat bearing surfaces.
2. Control cables are sufficiently coated by manufacturer, additional protection is unnecessary.
—CAUTION—
Be careful not to add too much oil. Excess oil will be thrown off
during operation and can cause pitting and burning of magneto
points.
3. Squeeze magneto cam follower felts at regular inspection periods. If oil appears on fingers, do not add
oil. If felt is dry, moisten with light oil.
APPLICATION OF GREASE
—CAUTION—
Be very careful when greasing the constant speed propeller hub.
Too much pressure can blow clamp gaskets.
Be careful when lubricating bearings and bearing surfaces with a grease gun. Ensure that gun is filled with
new, clean grease of the grade specified for application before applying lubricant to fittings.
l. Apply lubricant sparingly and wipe off any excess when a reservoir is not provided around a bearing.
2. Remove wheel bearings from wheel hub and clean thoroughly with a suitable solvent. Be sure
lubricant enters space between rollers in retainer ring when repacking with grease. Do not pack grease
into wheel hub.
3. When greasing the constant speed propeller hub, remove one grease fitting and apply grease to other
fitting until fresh grease appears at hole of removed fitting.
LUBRICATION CHART
Each airplane part to be lubricated, as depicted on the lubrication chart, is indicated by a frequency symbol
which shows time intervals between lubrications. Application symbols with frequency symbols show how
lubrication is applied. A parts nomenclature key, identifies part to be lubricated. Within frequency symbol is a
code letter which identifies type of lubricant to be used and a special instructions number which gives
instruction for lubricating a particular component.
