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:

Replace turbocharger if out of standard.Standard : 0.036 - 0.090 mm (0.0014 - 0.0035 in)

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer to EC-1012,
"Basic Inspection" (WITH EURO-ODB) or EC-1382, "Basic Inspection" (WITHOUT EURO-ODB).

Do not disconnect CONSULT-II until the end of this operation; it will be used to check engine rpm and
for error detection at the end of this operation.
3. Disconnect the battery cable from the negative terminal.
4. Remove charge air cooler. Refer to EM-144, "
Removal and Installation"
5. To prevent fuel from being injected during inspection, remove
fuel pump fuse [ENG CONT 2 (20A)] from fuse box on the left
side of engine room.

Among marks on fuse box, [ENG CONT 2 (20A)] is for fuel
pump fuse.
6. Remove glow plugs from all the cylinders. Refer to EM-162,
"Removal and Installation" .
CAUTION:

Before removal, clean the surrounding area to prevent
entry of any foreign materials into engine.

Carefully remove glow plugs to prevent any damage or
breakage.

Handle with care to avoid applying any shock to glow plugs.
7. Install compression gauge adapter (special service tool) to
installation holes of glow plugs and connect compression gauge
for diesel engine.
8. Connect the battery cable to the negative terminal.
9. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.

Always use a fully-charged battery to obtain specified engine
speed.
Compression pressure
Unit: kPa (bar, kg/cm2 , psi)/rpm

When engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.

If engine rpm exceeds the limit, check valve clearance and combustion chamber components (valves,
valve seats, cylinder head gaskets, piston rings, pistons, cylinder bores, cylinder block upper and lower
surfaces) and measure again.

If compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.

If compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.

DISASSEMBLY
1. Remove engine, transaxle and transfer assembly from the vehicle, then separate engine and transaxle
and transfer assembly. Refer to EM-222, "
ENGINE ASSEMBLY" .
2. Remove clutch cover and disk. Refer to CL-16, "
CLUTCH DISC, CLUTCH COVER AND FLYWHEEL" .
3. Install engine to engine stand as follows:
a. Remove flywheel.
b. Secure ring gear with the ring gear stopper (special service
tool), then loosen mounting bolts with TORX socket (size: T55,
Commercial Service Tools) and remove them. As an alternative
method hold crankshaft pulley with the pulley holder (special
service tool: KV10109300) to remove flywheel.
CAUTION:

Do not disassemble flywheel.

Do not place flywheel with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
c. Install the engine sub-attachment (special service tool) to the
rear side of cylinder block.

Align knock pins on cylinder block with pin holes on attach-
ment to install.
NOTE:
Installation bolts are part of engine sub-attachment.
d. Install the engine stand shaft (special service tool).
NOTE:
Use commercially available M12 (0.47 in) mounting bolts and
nuts (4 sets) with strength grade of 9T (minimum).
