81-00-32 Check /Adjust of the Waste Gate Controller
1. For checking the waste gate controller, remove the clip [1] and pull off the hose [2].
2. For the checking procedure use an air pressure device with the ability to stepwise
increase the pressure at the waste gate.
3. Apply the hose [3] from the chosen air pressure device [4] onto the port of the
controller and fix it with a clamp.
4. Slowly pump air in the controller by use of an air pressure device.
5. At 1,5 bar the pushrod must start to move.
6. If it is necessary to correct the adjustment, loosen the nut [5] and remove the circlip
[6].
Only apply an relative air pressure of 1,4 – 1,5 bar to the controller to move the
pushrod. Do not exceed the maximum allowable pressure of 3,5 bar.
7. To reduce the opening pressure, turn the fitting [7] out of the pushrod [8].
8. To increase the opening pressure, turn the fitting [7] into the pushrod [8].
9. Recapitulate this procedure until the pressure has 1,5 bar.
10. When the pressure is correct, mount the fitting [7] back onto the waste gate pin and
secure it with a circlip [6].
A new circlip has to be used for installation.
11. Torque the nut [5] with 6 Nm using Loctite 243.
When using Loctite, make sure, that the thread is free of grease and apply only a thin
film of Loctite.
Hold the pushrod [8] with a gripper.
12. Remove the hose [3] from the special tool [4] and apply the hose [2] onto the
controller port.
13. Secure the hose with new clamp.
14. Perform an engine ground run according to Chapter 71-00-03.
