O-360 AND ASSOCIATED MODELS
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 checkthese controls.
Exhaust Bypass Valve (TIO-360-A Series).
This valve is actuated by engine oil pressure and is set to predetermined open and closed clearances.
These clearances and the procedures for setting them are shown in Figure 5-5.
Exhaust Bypass Valve (TIO-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.
