Pressure Check

Mount a magnetically supported dial indicator on the upper portion of wastegate lever arm. Connect air pump (MS 554-03) at the pressure regulator inlet and insert a manometer (0-29 psi or 0-2 kg/cm² ) or special pressure gauge (Mot. 867).

Fig 1: Installation for Pressure Check Dial indicator should read .015" (.38 mm) at 12.7 psi (.89 kg/cm(2)).
At standing position, set dial indicator at zero. Using air pump, force air into the pressure regulator until dial indicator reaches .015" (.38 mm). Manometer reading should then be 12.7 psi (.89 kg/cm² ).
