Remove the wastegate actuator pressure line (1).
Connect a 5mm (3/16 in.) diamiater tube onto the nipple on the wastegate actuator (2).
CAUTION: Do not exceed 135kpa (20 psi) or damage to the wastegate actuator diaphragm wiil result.
Using Air Pressure Regulator W-18-MIL-1146AS, apply 69 ± 3.5 kPa (10 ±.5 psi.) to the wastegate actuator.
The wastegate actuator rod should move a minimum of 6 mm (0.236 in.)
CAUTION: Do not attempt to adjust the wastegate actuator rod. Doing so will cause unreliable engine operation.
If the wastegate actuator is out of specification, replace the turbocharger.
