To remove and to fit the actuator assembly of the waste-gate unit
Operation 9-7
To remove
Caution: Do not operate the actuator rod by hand, because the calibration of the actuator will be affected. This
may cause damage to the engine.
1 Disconnect the boost sensor pipe at the actuator.
2 Remove the clip (A1) that retains the actuator rod (A3).
3 Release the three setscrews (A6) that retain the waste-gate actuator and bracket assembly (A5) to the
turbocharger.
4 Remove the actuator and bracket assembly as a unit, and at the same time, lift the end of the actuator rod
off the arm of the waste-gate valve (A2).
To fit
Cautions:
l
Do not apply an air pressure of more than 207 kPa (30 lbf/in
2
) 2,1 kgf/cm
2
to the actuator. Higher pressures
may damage the actuator.
l
Do not operate the actuator rod by hand, because the calibration of the actuator will be affected. This may
cause damage to the engine.
1 Fit the actuator and bracket assembly (A5) to the turbocharger and tighten the three setscrews (A6).
Note: Do not put the end of the actuator rod (A3) onto the arm (A2) of the waste-gate valve.
2 Connect the actuator (B3), to an air supply that has a regulator (B5) and an accurate gauge (B4).
3 Operate the arm (B1) of the waste-gate valve by hand to check that the valve is free to move.
4 Push the arm of the waste-gate valve as far as possible toward the actuator and hold the arm in this position.
Slowly apply air pressure to the actuator until the end of the actuator rod (B2) will fit easily onto the arm of the
waste-gate valve.
5 If the end of the actuator rod will not fit easily onto the arm of the waste-gate valve, the rod of the actuator
assembly must be adjusted, see Operation 9-9.
6 Fit the clip (A1).
7 Release the air pressure.
8 Check the operation of the waste-gate unit, see Operation 9-8.
