BCDD Operating Pressure
- Turn adjusting screw as necessary until specified operating pressure is obtained. Turning the adjusting screw 1/4 turn clockwise decreases operating pressure and 1/4 turn counterclockwise increases pressure.
- After setting pressure to specification, accelerate engine and check adjustment. Turning adjusting screw 1/4 turn will change pressure of about .1 psi.
NOTE:
The BCDD operating pressure must be set to specifications after previous adjustment procedures, even if engine speed cannot be decreased to idling RPM.
