INSPECTION
1. INSPECT TURBINE SHAFT ROTATION
Grasp the edge of the turbine wheel and turn it. Check that the
impeller wheel turns smoothly.
If the impeller wheel does not turn or if it turns with a drag, re-
place the turbocharger assembly.
2. INSPECT AXIAL PLAY OF TURBINE SHAFT
(a) Using a dial indicator, insert the needle of the dial indicator
into the air tube side.
(b) Move the turbine shaft in an axial direction, measure the
axial play of the turbine shaft.
Maximum axial play:
0.110 mm (0.0045 in.)
If the axial play is greater than maximum, replace the turbochar-
ger assembly.
3. INSPECT RADIAL PLAY OF TURBINE SHAFT
(a) Using a dial indicator, insert the needle of the dial indicator
into the oil outlet hole and set it in the center of the turbine
shaft.
(b) Move the turbine shaft in a radial direction, measure the
radial play of the turbine shaft.
Maximum radial play:
0.162 mm (0.0064 in.)
If the axial play is greater than maximum, replace the turbochar-
ger assembly.
4. INSPECT WASTE GATE VALVE OPERATION
(a) Disconnect the actuator air hose from the housing, and
plug the hose end.
(b) Using SST, apply approx. 120 kPa (1.22 kgf/cm
2, 17.4
psi) of pressure to the actuator.
SST 09992-00242
(c) Move the actuator push rod, and check that the waste
gate valve is open.
If operation is not as specified, replace the No.1 turbocharger
assembly.
NOTICE:
Never apply more than 187 kPa (1.91 kgf/cm
2, 27.2 psi) of
pressure to the actuator.
(d) Reconnect the actuator air hose to the housing.

5. INSPECT EXHAUST BYPASS VALVE OPERATION
(a) Plug one side of the actuator air hose end.
(b) Using SST, apply approx. 98 kPa (1.00 kgf/cm
2, 14.2 psi)
of pressure to the actuator.
SST 09992 - 00242
(c) Move the actuator push rod, and check that the exhaust
bypass valve is open.
If operation is not as specified, replace the No.2 turbocharger
assembly.
NOTICE:
Never apply more than 187 kPa (1.91 kgf/cm
2, 27.2 psi) of
pressure to the actuator.
(d) Remove the plug from the actuator air hose end.
6. INSPECT INTAKE AIR CONTROL VALVE OPERATION
(a) Using SST, apply approx. 49 kPa (0.50 kgf/cm
2, 7.1 psi)
of pressure to the actuator.
SST 09992-00242
(b) Move the actuator push rod, and check that the control
valve is open.
If operation is not as specified, replace the control valve assem-
bly.
7. INSPECT EXHAUST GAS CONTROL VALVE FOR
DAMAGE
Move the actuator push rod and control valve, and check the
control valve for damage.
If the valve is damaged, replace the control valve assembly.
8. INSPECT AIR BYPASS VALVE OPERATION
(a) Check that air does not flow from port A to B.
(b) Apply vacuum to the actuator.
(c) Check that air flows from port A to B.
If operation is not as specified, replace the valve.

INSPECTION
1. REMOVE PRESSURE TANK
2. INSPECT PRESSURE TANK
(a) Check that air flows from port A to B.
(b) Check that air does not flow from port B to A.
(c) Apply 60.0 kPa (450 mmHg, 17.72 in.Hg) of vacuum to
port A, and check that there is no change in vacuum after
1 minute.
If operation is not as specified, replace the pressure tank.
