TURBOCHARGER INSPECTION
INSPECT ACTUATOR OPERATION
Disconnect the actuator hose and plug it.
Using SST (turbocharger pressure gauge) apply
approx. 71 kPa (0.72 kgf/cm’, 10.2 psi) of pressure to
the actuator and check that the rod moves.
If the rod does not move. replace the turbocharger
assembly.
SST 09992 —0024l
NOTICE: Never apply more than 88 kPa (0.90 kgf/cm‘,
12.8 psi) of pressure to the actuator.
INSPECT IMPELLER WHEEL 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 drags
heavily, replace the turbocharger assembly.
INSPECT AXIAL PLAY OF IMPELLER WHEEL
Insert a dial indicator into the intake side hold the
turbine wheel edge by hand, and check the axial play.
Standard clearance:
0.110 mm_(0.0043 in.) or less
If the axial D_l@¥._;l§ not as specified, replace the turbo-
charger assemlily.
INSPECT RADIAL PLAY OF IMPELLER WHEEL
From oil outlet hole, insert a dial indicator through the
hole in the spacer bearing and set it in the center of
the impeller shaft.
Move the impeller shaft in a radial direction, measure
the radial play of the impeller shaft.
Standard clearance:
0.136 mm (0.005-G in.) or less
If the radial play is not as specified, replace the turbo-
charger assembly.
