Attach a dial indicator (1) as shown, so that its shaft is in line with the wastegate actuator rod. Set the indicator to
zero, with no air pressure applied to the wastegate capยญ sule.
Connect clean regulated air pressure and a pressure gauge to the capsule (2). Apply 200 kPa [29 psi] to makesure the wastegate is functioning properly.
The rod should move approximately 5 mm [0.200 in] withยญ out any sticking or air leakage.
NOTE: No air should be heard to leak through a functional wastegate capsule.
NOTE: A small amount of travel when air pressure is first applied is normal, the tolerance is being removed from the
system.
Replace the actuator if no movement of the actuator rod and lever is detected. Refer to Procedure 3-05.
