PIPER AZTEC SERVICE MANUAL
2-88. LUBRICATION INSTRUCTIONS.
Proper lubrication procedures are of immeasurable value both as
a means of prolonging the service life of the airplane and as a means of reducing the frequency of extensive and
expensive repairs. The periodic application of recommended lubricants to their relevent bearing surfaces, as
detailed in the following paragraphs, together with the observance of cleanliness, will insure the maximum
efficiency and utmost service of all moving parts. Lubrication instruction regarding the locations, time
intervals, and type of lubricants used may be found in Lubrication Chart. To insure best possible results from
the application of lubricants, the following precautions should be observed:
a. Use recommended lubricants. Where general purpose lubricating oil is specified, but unavailable,
clean engine oil may be used as a satisfactory substitute. (See Consumable Materials Chart.)
b. Check the components to be lubricated for evidence of excessive wear and replace them as
necessary.
c. Remove all excess lubricants from components in order to prevent the collection of dirt and sand in
abrasive quantities capable of causing excessive wear or damage to bearing surfaces.
2-89. APPLICATION OF OIL. Whenever specific instructions for lubrication of mechanisms requiring
lubrication are not available, observe the following precautions:
a. Apply oil sparingly, never more than enough to coat the bearing surfaces.
b. Since the cables are sufficiently coated by the manufacturer,
additional protection for the
prevention of corrosion is unnecessary.
c. Squeeze the magneto cam follower felts at regular inspection periods. If oil appears on fingers, do
not add oil. If the felt is dry, moisten with Bendix Breaker Felt Lubricant 10-86527. (Bendix Electrical
Components Division Sidney, N.Y. 13838.)
CAUTION
Be careful not to add to much oil, because the excess will be thrown off during operation and will cause
pitting and burning of the magneto points.
2-90. 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 apply lubricant to the grease fittings.
a. Where a reservoir is not provided around a bearing, apply the lubricant sparingly and wipe off any
excess.
