EXHAUST MANIFOLD AND TURBOCHARGER

INSPECTION AFTER DISASSEMBLY
Surface Distortion

Check the distortion on the mounting surface in the six directions
using a straightedge and a feeler gauge.

If it exceeds the limit, replace exhaust manifold.
TurbochargerEBS00LRJ
CAUTION:
When the compressor wheel turbine, wheel or rotor shaft is damaged, remove all the fragments and
foreign matter left in the following passages in order to prevent a secondary malfunction:
ROTOR SHAFT CLEARANCE

Make sure that the rotor shaft rotates smoothly without any
resistance when it is rotated by your fingertips.

Make sure that the rotor shaft is not loose when it is moved ver-
tically or horizontally.

Measure looseness with a dial indicator inserting its measuring
rod through oil drain hole of turbocharger.

Replace turbocharger if out of standard.Limit : 0.3 mm (0.012 in)

ROTOR SHAFT END PLAY

Place a dial indicator at the rotor shaft end in the axial direction
to measure the end play.

Replace turbocharger if out of standard.
TURBINE WHEEL

Make sure that there is no engine oil adhesion.

Make sure that there is no carbon accumulation.

Make sure that blades of turbine wheel are not bent or broken.

Make sure that turbine wheel does not interfere with turbine
housing.

If anything above is found, replace turbocharger.
COMPRESSOR WHEEL

Make sure that there is no engine oil adhesion inside the air
inlet.

Make sure that compressor wheel does not interfere with com-
pressor housing.

Make sure that compressor wheel is not bent or broken.

If anything above is found, replace turbocharger.
TURBOCHARGER BOOST CONTROL ACTUATOR

Connect the handy vacuum pump to the actuator, and make
sure that the rod strokes smoothly in compliance with the follow-
ing pressure.

Pressure to be applied at actuator part to move rod end as fol-
lows:

EXHAUST MANIFOLD AND TURBOCHARGER

TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:

Make sure that the engine oil level is between “MIN” and “MAX” of the oil level gauge. (When engine oil
amount is more than “MAX”, engine oil flows into the inlet duct through blow-by gas passage, and turbo-
charger is misjudged malfunction.)

Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.

Replace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.

If no malfunction is found after the unit inspections, judge that the turbocharger body has no malfunction.
Check the other parts again.

Removal and InstallationEBS00LRP
CAUTION:

Before removing and installing fuel pump, be sure to remove sprocket. Do not loosen or remove
installation nut in the center of fuel pump. If loosened or removed, replace fuel pump.

After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.

When installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.
REMOVAL
1. Remove engine coolant reservoir tank. Refer to CO-35, "RADIATOR" .
2. Remove charge air cooler. Refer to EM-144, "
Removal and Installation" .
3. Remove RH engine mounting insulator and bracket. Refer to EM-222, "
ENGINE ASSEMBLY" .
4. Pull power steering reservoir tank out of brackets to move power steering piping. Refer to PS-37,
"HYDRAULIC LINE" .
CAUTION:
To avoid removing power steering reservoir tank out of brackets, move it with power steering pip-
ing aside.

Removal and Installation (2WD Models)EBS01FKK
WARNING:

Situate vehicle on a flat and solid surface.

Place chocks at front and back of rear wheels.

For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:

Always be careful to work safely, avoid forceful or uninstructed operations.

Do not start working until exhaust system and engine coolant are cool enough.

If items or work required are not covered by the engine main body section, refer to the applicable
sections.

Always use the support point specified for lifting.

Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.

For supporting points for lifting and jacking point at rear axle, refer to GI-36, "Garage Jack and
Safety Stand" .
