CESSNA SECTION 7
MODEL T182T NAV III AIRPLANE AND SYSTEM DESCRIPTION
GFC 700 AFCS
U.S.
ENGINE (Continued)
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 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.
The airplane is delivered from the factory with corrosion preventive oil
in the engine. If, during the first 25 hours, oil must be added, use only
MIL-L- 22851 or SAE J1899 Ashless Dispersant Oil.
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 with one
additional quart 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 dipstick/filler 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 POH.
