Typical exampleNote: The turbocharger is a nonserviceable item. The pressure for the wastegate can be checked, but not adjusted.
Install Tooling (A). Tooling (A) is shown in illustration 1. Align the dial gauge on Tooling (A) to the actuator rod (1) .
Remove the air hose to the actuator. Install a suitable air line (2) that can be adjusted in order to give the correct pressure.
Slowly apply air pressure to the wastegate so that the actuator rod moves 1.0 mm (0.039 inch). The air pressure should be within 107 to 117 kPa (15.5 to 17.0 psi). Ensure that the dial indicator returns to zero when the air pressure is released. Repeat the test several times. This will ensure that an accurate reading is obtained.Note: Do not exceed 205 kPa (30 psi) in order to check the actuator. Refer to Specification, "Turbocharger" for information on the correct pressure setting for your actuator.
