SECTION V
INSTALLATION IN AIRCRAFT AND REMOVAL
5-1. ACCESSORIES.
5-2. OPTIONAL ACCESSORIES.
If
a hydraulic pump
or a vacuum pump is to be installed on a GO-300-A,
-B or -C engines, remove the pad cover from lower
right side of reduction unit housing.
If
the pump is
to be installed on GO-300-D or -E engine, remove
the pad cover from the rear of the starter adapter.
(See figure 6.) Install a new gasket and attach the
pump with plain washers, new lock washers and the original
cover attaching nuts. If the aircraft has an oil dilution valve,
install the fitting in place of the plug immediately above the
pressure oil screen in the crankcase cover. For GO-300-Band -
E engines remove the governor mount pad cover and install
the propeller governor. The governor pad is located on the
upper right rear of the reduction unit housing. Install a new
gasket and attach the governor with plain washers, new lock
washers and plain nuts.
5-3. INSTALLATION.
5-4. DIMENSIONS. Principal dimensions of the
engine which affect mounting and locations of control
and instrument connections are shown in the installa-
tion drawing (Figure 5).
5-5. PRECAUTION. The engine assumes a slightly
tail heavy attitude when suspended by its lifting eye.
It may be necessary to hold down on the front end in
order to align the engine mount brackets with attach-
ing brackets of the aircraft. Make sure that the
mount bushings all contact the aircraft brackets
uniformly and seat fully on the engine mount bracket
when the mounting bolts are installed. Tighten the
mounting bolts to the torque specified by the aircraft
manufacturer.
5-6. CONTROL CONNECTIONS. The magneto switch
wires should be installed first. Before installing
the switch wire terminals in the magneto sockets, check
each with a buzzer and battery for continuity with the
switch in "LEFT" and "RIGHT" positions. Remember
that the left magneto should be grounded through the
switch when the switch is turned to "RIGHT" pOSition
and the right magneto should be grounded with the
switch in the "LEFT" position. This is important
when shooting ignition troubles. Connect the wires to
the magnetos.
5-7. Connect the throttle and mixture controls where
indicated on installation drawing and check each for
full range of operation. For GO-300-A, -B and -C
engines, connect the starter detent cable to the lever,
on the starter, then operate the control to make
certain the starter pinion is fully engaging the crank-
shaft gear. On all models connect the electrical lead
to the starter switch. Connect the generator field
coil "F" and armature "A" electrical leads to the
terminals so designated on the installation drawing.
Remove the pipe plug and install the necessary fittings
for oil dilution at the location indicated on the in-
stallation drawing
if
the aircraft incorporates an oil
dilution system.
5-8. INSTRUMENT CONNECTIONS. Apply a film of
grease to the flexible shaft end of the mechanical drive
tachometer, and connect the drive to the tachometer
drive housing. Make sure the flexible shaft conduit
is properly supported and without sharp bends. Con-
nect the oil pressure gauge tube in the location in-
dicated on the installation drawing. Remove the plug
and gasket below the oil cooler and install the oil
temperature gauge capillary with a new gasket. Con-
nect the cylinder head temperature gauge to the
thermocouple previously installed. Connect the intake
manifold pressure gauge to the intake manifold riser.
5-9. BLAST TUBE AND BREATHER. To provide the
generator with COOling air, connect the aircraft blast
tube to the connector projecting from the generator
brush access cover. Install the aircraft breather
hose on the crankcase breather and secure it with
hose clamps.
5-10. FUEL SUPPLY LINE. Connect the fuel line to
a suitable fitting installed in the 1/4 in. N.P. T. hole of
the carburetor on the level of the manual mixture
control lever.
5-11. AIRCRAFT PARTS. Install whatever engine
baffles are required by the cowling of the aircraft in
such a manner as to form a tight seal between the
upper and lower compartments so that all cooling air
will be forced to travel through the cylinder fins and
the oil cooler fins. Attach the overboard drain lines
Install the carburetor air scoop and air filter parts
and the heat valve control. Make sure that the control
will move the valve through its full range. Complete
the installation of any other aircraft parts removed
from the engine compartment, and install all parts
of the cowling.
5-12. LUBRICATION. There are no grease fittings or
points to be lubricated other than filling of the oil
sump. Fill the sump with clean engine lubricating oil
of a reputable brand and of the viscosity grade rec-
ommended in Table VTI, according to climatic condi-
tion. The choice of detergent or straight mineral oil
should be based on operating experience in the climate
and the conditions of operation anticipated. Detergent
oil is recommended only if it is used conSistently
from the time the engine is installed, since it will
