05-30 LUBRICATION
Foreword
Proper lubrication procedures allow for a/c service life extension and for reducing the
frequency of extensive and expensive repairs.
In addition, periodic application of recommended lubricants, as detailed in the following
paragraphs, and observance of parts cleanliness will insure the maximum efficiency of
all moving parts.
Lubrication instructions concerning the locations, time intervals and type of lubricants
used may be found in the Lubrication Charts herein reported. Reference is made to the
inspection caps and removable parts shown on Chapter 06-10.
To insure the best results from the application of lubricants, the following precautions
should be observed:
- Use recommended lubricants. Where general purpose lubricating oil is specified, but
unavailable, clean engine oil may be used as satisfactory substitute.
- Check the components to be lubricated for evidence of excessive wear and replace
them as necessary.
- 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.
Since the control cables are sufficiently coated by the manufacturer, additional protec-
tion for corrosion prevention is unnecessary.
Care must be taken when lubricating bearings and bearing surfaces with a grease gun;
insure that gun is filled with new clean grease of the grade specified for the particular
application before applying lubricant to the grease fitting.
If the aircraft stays inactive for long periods of time, it should be
lubricated every 90 days in accordance with Lubrication Charts.
