Turbocharger5Turbocharger west gate adjustment - Regolazione corsa astacomando valvola " Waste gate "150Disconnect westgate tube 7 from the turbocharger compressor side.Using a T-joint connect a pressure gauge 4 (scale 0 to 2 bar) andwith 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 thepressure 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 asterminal 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 thecalibration pressure.During the rotation of terminal 2, the rod should not undergo anytorsion.. ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... ...................................................................................................................................................... .....................................................................................................................................................FOCS Workshop Manual_cod. 1.5302.351_7° ed_ rev. 06- 67 -
