WASTE GATE ACTUATOR CHECK <4M4>

1.Connect a manual pump (pressure-application type) to nipple. caution In order to avoid damage to the diaphragm, do not apply a pressure of 115 kPa <4M40> 153 kPa <4M40> or higher. 2.While gradually applying pressure, check the pressure that begins to activate (approximately 1 mm stroke) the waste gate actuator rod. Standard value: Approximately 96 kPa <4M40>kPa 118.8 - 124.2 kPa <4M41> 3.If there is a significant deviation from the standard value, check the actuator or the waste gate valve: replace actuator or turbocharger assembly if necessary.
