Turbocharger west gate adjustment - Regolazione corsa
asta comando valvola " Waste gate "
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
5.
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.
