3. Squeeze the magneto cam follower felt at regular inspection periods. If oil appears on fingers, do not
add oil. If the felt is dry, moisten with light oil.
—CAUTION—
Be careful not to add too much oil, because the excess will be
thrown off during operation and will cause pitting and burning
of the magneto points.
APPLICATION OF GREASE.
Care must be taken when lubricating bearings and bearing surfaces with a grease gun, to insure that gun is
filled with new, clean grease of the grade specified for the particular application before applying lubricant to
the grease fittings.
1. Where a reservoir is not provided around a bearing, apply the lubricant sparingly and wipe off any
excess.
2. Remove wheel bearings from the wheel hub and clean thoroughly with a suitable solvent. When
repacking with grease, be sure the lubricant enters the space between the rollers in the retainer ring. Do not
pack the grease into the wheel hub.
3. Use extra care when greasing the constant speed propeller hub to avoid blowing the clamp gaskets.
Remove one grease fitting and apply grease to the other fitting until fresh grease appears at the hole of the
removed fitting.
LUBRICATION CHARTS.
The lubrication charts consist of individual illustrations for the various aircraft systems, and each
component to be lubricated is indicated by a number, the type of lubricant and the frequency of application.
Special instructions are listed at the beginning of the lubrication charts and with the applicable component
illustration.
