Application Of Oil; Application Grease; Winterization Plate - Piper ARROW III Service Manual

a. Use recommended lubricants. Where general purpose lubricating oil is specified, but unavailable,
clean engine oil may be used as a staisfactory 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.
If the airplane is inactive for long periods of time, it should be lubricated in
accordance with Lubrication Chart every 90 days.
2-69. 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 control cables are sufficiently coated by the manufacturer, additional protection for the
prevention of corrosion is unnecessary.
c. 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.
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.
2-70. APPLICATION 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.
c. 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.
2-71. WINTERIZATION PLATE. (PA-28R-201 Only.) 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 plenum chamber. When the plate is not being used it can be stowed on a bracket, provided for this
purpose, located on the oil cooler plenum chamber.
(PA-28R-201T Only.) The winterization plate is mounted on the firewall when not in use (temperature is
above 50°F). The plate is mounted to the oil cooler baffle when ambient temperature is 50°F or less.
