TEXTRON LYCOMING OPERATOR'S MANUAL
0-360 and ASSOCIATED MODELS SECTION 5
The density controller
is set to the curve,
see figure 5-3, under the
following conditions: Engine
stabilized at operating conditions,
full
throttle with oil pressure at 80 psi ± 5 psi.
If it is suspected
that the manifold pressure
is not within limits, it may
be checked to the curve.
EXAMPLE
Operating
at the
stated conditions
with a compressor
discharge
temperature
of 120°F., the
manifold pressure
should be
34.8 in. Hg. ± .3
in. Hg.
If the manifold
pressure is found
to be out of
limits, the cause
might be
found
either in the density
controller,
the differential
pressure controller,
or the waste gate. It is
recommended that an authorized
overhaul facility
check these controls.
Exhaust Bypass Valve (TIO-360-A Series).
This valve
is actuated
by engine oil pressure
and is
set to predetermin-
ed open
and closed
clearances. These
clearances and
the procedures
for
setting them are shown in Figure 5-4.
Exhaust
Bypass Valve (TI0-360-C1A6D).
This valve
is mechanically
controlled by
a flexible linkage
connected to
the injector throttle arm and the wastegate control arm.
Adjust linkage as follows:
(1)
Move injector
throttle
arm to
full-open position.
(2) Insert a .005-.015
inch feeler
gage between
the bypass
butterfly
valve, in
the closed
position, and
the bypass
housing.
(3)
Adjust linkage
until the bypass
valve control
arm is at
the full-
closed stop
position.
