Inspect Axial Play Of Turbine Shaft

(a) Using a dial indicator, insert the needle of the dial indicator into the exhaust side.

(b) Move the turbine shaft in an axial direction, measure the axial play of the turbine shaft.

Maximum axial play: 0.15 mm (0.0063 in.) If the axial play is greater than maximum, replace the turbocharger.

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

(b) Move the turbine shaft in a radial direction, measure the radial play of the turbine shaft. Maximum radial play: 0.11 mm (0.0043 in.) i

If the radial play is greater than maximum, replace the turbo-charger. j

4. INSPECT ACTUATOR AND WASTE GATE VALVE OPERATION i ^ |

(a) Disconnect the actuator hose from the compressor hous-ing' | , \ v j

(b) Using SST, apply approx. 116 kPa (1.1$ kgf/cm2,16.7 psi) of pressure to the actuator. j, ^ , ( SST 09992-00242 ^ 1

(c) Move the actuator push>od, and check that the waste gate valve is open.

If the rod does not move, replace the actuator or turbocharger. OWtP« IOH NOTICE:

Never apply more than 141 kPa (1.44 kgf/cm2, 20.5 psi) of pressure to the actuator.

(d) Reconnect the actuator hose to the compressor housing.

5. REMOVE BEARING HOUSING SIDE PLATE FROM TURBOCHARGER

Remove the 2 bolts, side plate and gasket.

6. REMOVE ACTUATOR

(a) Disconnect the actuator hose form the compressor housing.

(b) Using SST, apply pressure to the actuator. SST 09992-00242 J

NOTICE:

Never apply more than 141 kPa (1.44 kgf/cm2, 20.5 psi) of pressure to the actuator.

(c) Remove the 2 bolts holding the actuator to the compressor housing.

IA (d) Remove the E-ring holding the actuator push rod to the waste gate valve link, and remove the actuator.

7. REMOVE COMPRESSOR HOUSING

(a) Place the matchmarks on the compressor housing and bearing housing.
