Disconnect westgate tube 7 from the turbocharger compressor

side.

Using a T-joint connect a pressure gauge 4 (scale 0 to 2 bar)

and with the compressed air network pipe complete with reducer

The network air supply pressure must be from 1.5 to 2 bar.

Make a hole B in the pressure gauge pipe of 1.55 mm in

diameter.

This will help bleeding some air and stabilizing pressure in the

pressure gauge.

Set up a dial gauge 6 so that the feeler is rested on terminal 2.

Via the pressure reducer 5 convey some air to the actuator so

as terminal 2 is pushed forwards by A (A=1 mm).

The pressure read in the pressure gauge must be 830÷890 mm

Hg (1.11÷1.19 bar).

If the pressure is lower than the given value proceed as follows.

Unscrew locknut 1.

Remove split pin 9 and disconnect rod 8, “waste gate” control

valve.

Keeping the rod steady tighten terminal 2 until you reach the

calibration pressure.

During the rotation of terminal 2, the rod should not undergo any

torsion.
