Systems Description
NOTE
In order to promate proper ring seating, cruise
power settings of 65% to 75% should be used
until a total of 50 hours has accumulated or
until oil consumption has stabilized. This
recommendation is applicable to in-service
engines following cylinder replacementor top-
overhaul of one or more cylinders, as we l l as to
new engines .
LUBRICATION SYSTEM
The engine oil system is the wet-sump type and has an 8-
quart capacity. Oil operating temperatures are controlled
by im automatic thermostat bypass control. The bypass
eontroi will limit oil flow through the oil cooler when
operating temperatures are below normal, and will permit
the oil to bypass the cooler if it should become blocked .
CARBURETOR HEAT
There is a possibility of ice forming in the induction sys-
tem under certain moist atmospheric conditions . Gen-
erally ice mayform in the vicinity of the carburetor butter-
fly and may build up enough that a drop in power output
could result. The induction installation is equipped with a
system for preheating the incoming air to the carburetor.
The air preheater is essentially a tube or jacket through
which the exhaust pipe from one or more cylinders is
passed, and the air flowing over these surfaces is heated .
A push -pull eontroi located on the eontroi eonsole actu-
ates a diverter gate wh ich allow:;; the hot oir to mix with the
cold air in the induction chamber before it enters the
carburetor. For further information concerning the use of
carburetor heat eonsuit engine manufacturer's operating
manual.
