NEW ENGINE BREAK IN AND OPERATION
The engine run-in was accomplished at the factory and is ready for
the full range of use. It is, however, suggested that cruising be
accomplished at 75% power as much as practicable until a total of
50 hours has accumulated or oil consumption has stabilized. This
will ensure proper seating of the piston rings.
ENGINE LUBRICATION SYSTEM
The engine utilizes a full pressure, wet sump type lubrication
system with aviation grade oil as the lubricant. The capacity of the
engine sump (located on the bottom of the engine) is nine quarts
(one additional quart is contained in the engine oil filter). Oil is
drawn from the sump through a filter screen on the end of a pickup
tube to the engine-driven oil pump. Oil from the pump passes
through a full-flow oil filter, a pressure relief valve at the rear of the
right oil gallery, and a thermostatically controlled remote oil cooler.
Oil from the remote cooler is then circulated to the left oil gallery
and propeller governor. The engine parts are then lubricated by oil
from the galleries. After lubricating the engine, the oil returns to the
sump by gravity. The filter adapter in the full-flow filter is equipped
with a bypass valve which will cause lubricating oil to bypass the
filter in the event the filter becomes plugged, or the oil temperature
is extremely cold.
An oil
dipsticklfiller tube is located on the upper left side of the
engine case. The dipstick and oil filler tube are accessed through a
door located on the left center portion of the upper engine cowling.
The engine should not be operated on less than four quarts of oil.
To minimize loss of oil through the breather, fill to eight quarts for
normal flights of less than three hours. For extended flight, fill to
nine quarts (dipstick indication only). For engine oil grade and
specifications, refer to Section 8 of this handbook.
