PIPER CHEROKEE WARRIOR SERVICE MANUAL
b. When changing from straight mineral oil to compounded oil, the following precautionary steps
should be taken:
1. Do not add additive oil to straight mineral oil. Drain the straight mineral oil from the engine
and fill with additive oil.
2. Do not operate the engine longer than five hours before the first oil change.
3. Check all oil screens for evidence of sludge or plugging and change oil every ten hours if
sludge conditions are evident. Resume normal oil drain periods after sludge conditions improve.

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 relevant 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 inter-
vals, and type of lubricants used may be found in the Lubrication Chart. To insure the 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.
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.
2-70.
A P P L I C ATION 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 control cables are sufficiently coated by the manufacturer, additional protection for the
prevention of corrosion is unnecessary.
2-71.
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.
a. Where a reservoir is not provided around a bearing, apply the lubricant sparingly and wipe off any
excess.
b. 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.
2-72.
WINTERIZATION PLATE: For winter operations there is a winterization plate kit available. When
the ambient temperature is 50°F or less the plate is installed on the inlet opening of the oil cooler pleunum
chamber.
