From the oil outlet hole, insert the dial indicator
through the hole in the spacer bearing and
set
it
in
the center of the turbine shaft.
(b)
Moving the turbine shaft in
a
radial direction, meas-
ure the radial play of the shaft.

INSPECT ACT1
JATOR OPERATION
(a)
Disconnect the actuator hose.
(b)
Using SST (turbocharger pressure gauge), apply ap-
prox. 0.81 kg/cm2
(1
1.5
psi,
79
kPa) of pressure to
the actuator and check that the rod moves.
SST 09992-00241
If the rod does not move, replace the turbocharger assem-
bly.
NOTICE: Never apply more than
0.95
kg/cm2
(13.5
psi,
94
kPa) of pressure to the actuator.
NOTICE: After replacing the turbocharger assembly,
pour approx.
20
cc
(1.2
cu in.) of new oil into the oil inlet
and turn the impeller wheel by hand to splash oil on the
bearing.
INSTALL TURBINE OUTLET ELBOW
l
nstall
a
new gasket and the turbine outlet elbow with the
four nuts.
