1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated forself-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
I 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.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
I Intercooler
I Throttle body
I Rocker cover
6. To prevent fuel from being injected during inspection, remove fuel injection pump fuse [ENG CONT A/T (15A)] from fuse box
on the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
I Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
I Carefully remove glow plugs to prevent any damage or
breakage.
I Handle with care to avoid applying any shock to glow
plugs.
8. Install adapter (SST) to installation holes of glow plugs and connect compression gauge for diesel engine.
:15-19N ×m (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
9. Connect battery negative terminal.
10. Set the ignition switch to ªSTARTº and crank. When gauge pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
I Always use a fully-charged battery to obtain specified
engine speed.
Unit: kPa (bar, kg/cm2, psi)/rpm
Standard MinimumDifference limit between
cylinders
2,942 (29.42, 30.0, 427)/ 200 2,452 (24.52, 25.0, 356)/
200 294 (2.94, 3.0, 43)/200
I
When engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
I 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.
11. Complete this operation as follows:
a. Turn the ignition switch to ªOFFº.
b. Disconnect battery negative terminal.
c. Replace glow plug oil seals and install glow plugs.
d. Install fuel injection pump fuse [ENG CONT A/T (15A)].
e. Connect battery negative terminal.
f. Using CONSULT-II make sure no error code is indicated for items of self-diagnosis. Refer to EC section, ªTrouble Diagno-
sis Ð Indexº.

http://vnx.su/  

Rotor shaft end play
Place a dial gauge at the rotor shaft end in the axial direction to
measure the end play.Standard: 0.044 - 0.083 mm (0.0017 - 0.0033 in)
Turbine wheel
ICheck that there is no oil adhesion.
I Check that there is no carbon accumulation.
I Check that blades of the turbine wheel are not bent or broken.
I Check that the turbine wheel does not interfere with the turbine
housing.
Compressor wheel
ICheck that there is no oil adhesion inside the air inlet.
I Check that the compressor wheel does not interfere with the
compressor housing.
I Check that the wheel is not bent or broken.
VNT control actuator
IConnect the handy pump to the actuator, and check that the rod
strokes smoothly in compliance with the following pressure.
I First, apply the inspection negative pressure of about þ66.7
kPa (þ667 mbar, þ500 mmHg, 19.69 inHg), and then measure
the values while reducing the negative pressure to 0.
Standard (Vacuum pressure/rod stroke amount): þ46.9 1.3 kPa (þ469 13 mbar, þ352 10 mmHg,
þ13.86 0.39 inHg)/0.2 mm (0.008 in)
þ30.8 0.7 kPa (þ308 7 mbar, þ231 5 mmHg,
þ9.09 0.20 inHg)/5.0 mm (0.197 in)

Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction. Refer
to EC section, ªECM Terminals and Reference Valueº in ªTROUBLE
DIAGNOSIS Ð GENERAL DESCRIPTIONº.
ICheck that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
I Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
I Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
I If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.
