SERVICE ADJUSTMENT PROCEDURES
HUB END PLAY INSPECTIONNO2FAAB --- ’
1. Jack up the vehicle and remove the front wheels.
2.Remove the disc brake caliper and suspend it with a wire.
(Refer to GROUP
5-Service Adjustment Procedures.)
3.Attach a dial indicator as shown in the illustration, and thenmeasure the axial play while moving the hub back and
forth.Limit
: 0.2 mm (.008 in.) or less
NOTE
Secure the brake disc and hub by the wheel nut so that thebrake disc won’t come off the hub.
4.If axial play exceeds the limit, disassemble and check parts.
FRONT WHEEL ALIGNMENTNOZFBAQ
NOTEThe front suspension assembly must be free of worn, loose or
damaged parts prior to measurement of front wheel align-

29. REMOVAL OF TURBOCHARGER ASSEMBLY
Remove the turbocharger assembly with the exhaust fitting,water
pipe A, water pipe 6 and the oil pipe attached to it.3B.REMOVAL OF OIL PIPE
CautionAfter disconnecting the oil pipe, take care that foreign
material does not enter the oil passage hole of the
turbocharger assembly.
INSPECTIONNllLCAC
TURBOCHARGER ASSEMBLY CHECKl
Visually check the turbine wheel and the compressor wheelfor
cracking or other damage.
lCheck whether the turbine wheel and the compressor wheel
can be easily turned by hand.l
Check for oil leakage from the turbocharger assembly.l
Check whether or not the waste gate valve remains open.
If any problem is found, replace the part after disassembly.
OIL PIPE AND OIL-RETURN PIPE CHECK
Check the oil pipe and oil-return pipe for clogging, bending, or
other damage.
If there is clogging, clean it.
SERVICE POINTS OF INSTALLATIONNllLDAC-x_3SlNSTALLATlON OF OIL PlPE
Supply clean engine oil through the oil pipe installation hole
of the turbocharger assembly.
29. INSTALLATION OF TURBOCHARGER ASSEMBLY
Clean the alignment surfaces shown in the illustration.
Caution
When cleaning, care must be taken so that a piece of the
gasket does not enter the oil passage hole.

INSTALLATIQN OF CARTRIDGE ASSEMBLY
(I1 Coat the outer circumference of the cartridge assembly
O-ring with a thin film of engine oil.
(29 Install the cartridge assembly on the compressor cover
by aligning the dowel pin.
CautionWhen installing the cartridge assembly on the
compressor cover, be careful not to damage the
compressor wheel blades.5. INSTALLATION OF SNAP RING
Place the cartridge assembly with the compressor cover
faced down and install the snap ring.
CautionInstall the snap ring with the tapered side of its outside
diameter up.4. INSTALLATION OF TURBINE HOUSING
Install the compressor cover and cartridge assembly on the
turbine housing with the dowel pin in alignment.
Caution
1. Be careful not to damage the blades of the turbine
wheel.
2. Be careful to install the turbine housing in the correct
direction.
TEST OF WASTE GATE ACTUATOR OPERATIONNllLlAA
Using a tester, apply a pressure to the actuator and make surethat the
rod moves.Standard value:
M/T76.7
kPa (11.1 psi)
A/T72.0
kPa (10.4 psi)
CautionDo not apply a pressure of more than 85.3
kPa (12.4 psi) to
