SPECIAL SET-UP PROCEDURES FOR THE TSIO-360E, EB, F,FB, GB
AND
LTSIO-360E, EB
ENGINES
A. Takeoff rated MP and RPM are obtained at approximately
40" throttle travel.
B. Engine critical altitude adjustment is controlled by a ground adjustable screw-type
wastegate on the exhaust bypass pipe at the turbocharger location. This adjustment is preset
and only minor changes should be required. Adjustment is as follows:
Approximately 1000
feet
increase in critical altitude per one revolution of screw clockwise; approximately 1000
feet reduction in critical altitude per one revolution of screw counterclockwise. Unlock and
lock jam nut before and after adjustment.
NOTE.
.
. Setting the exhaust bypass bolt is extremely important. This setting determines
Full
Throttle manifold pressure and critical altitude and must be properly adjusted before the fuel
system can be set up accurately.
NOTE.
.
.
See General Instructions for adjusting turbocharged engine fuel systems.
C.
Rated manifold pressure for a given altitude should be achieved on take-off roll. If
rated MAP cannot be obtained, check for exhaust leaks, turbocharger condition, or calibration
of overboost valve.
D. To check actual critical altitude, the aircraft must be flown. Refer to Aircraft Service
Manual for test flight procedures. If critical altitude is not correct and fixed wastegate is
readjusted, the metered fuel flow must be rechecked and set to max. power (full throttle)
values.
NOTE.
. . For further information on adjusting fuel injection systems see
TCM
Service
Bulletin M84-6RI or current revision as applicable.
