BCDD Operating Pressure

  1. To check pressure, engine should be at normal operating temperature, idle speed set to specifications and transmission in Neutral. Connect a tachometer to engine and a vacuum gauge to intake manifold.
  2. Run the engine under no load and note vacuum reading. Increase engine speed to 3000-3500 RPM, then quickly close the throttle.
  3. Manifold vacuum should increase 23.6 in. Hg or more. Gradually decrease to idle level. Operating pressure should be 21.6-23.2 in. Hg. If pressures at idle are not to specification, proceed to ADJUSTMENTS.
