SECTION 7 CESSNA
AIRPLANE & SYSTEMS DESCRIPTION MODEL 182T
The manifold pressure gauge is part of the manifold pressure
gauge/fuel flow indicator located on the left side of the pilot's
instrument panel. The gauge is direct reading and indicates
induction air manifold pressure in inches of mercury. It has a normal
operating range (green arc) of 15 to 23 In. Hg. The fuel flow
indicator is a fuel pressure indicator calibrated in flow rate. The fuel
pressure is taken at the flow divider valve by a pressure transducer.
The pressure transducer receives a constant voltage from the
indicator and returns a variable voltage depending on the pressure,
as pressure increases, voltage increases. The indicator is marked
in gallons per hour and has a green arc from 0 to 15 gal./hr. There
is no red line or maximum fuel flow (pressure) limitation. There may
be some atmospheric conditions that would result in fuel flow rates
that exceed the maximum marked value on the indicator (i.e., very
low density altitude and full throttle). If the indicator is pegged out
because of these conditions, the indicator will not be damaged, and
will return to operating range when the throttle is retarded to cruise
power settings.
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.
