1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
IDo 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.
IIntercooler
IThrottle body
IRocker 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.
IBefore removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
ICarefully remove glow plugs to prevent any damage or
breakage.
IHandle 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.
IAlways 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)/
2002,452 (24.52, 25.0, 356)/
200294 (2.94, 3.0, 43)/200
IWhen engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
IIf 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.

12. Remove the idler gears (A) and (B).
ICheck the backlash of each gear before removing. Refer to
ªBACKLASH OF EACH GEARº, ªInspectionº.
CAUTION:
IDo not loosen the internal mechanism setting bolt of the
idler gear (A). (The idler gear cannot be reused when the
internal mechanism is released.)
IDuring removal of the idler gears (A) and (B), do not face
the rear side downward as the idler shaft will drop.
13. Set the fuel injection timing gear with the pulley holder (SST).
14. Remove injection pump timing gear.
15. Extract the balancer shaft taking care not to damage the inner
bushes of the cylinder block.
16. Remove the fuel injection pump.
17. Remove the front plate.
Inspection
BACKLASH OF EACH GEAR
Method using a fuse wire
ITighten the holding bolts of each gear to specification.
IPlace a wire in the biting area of the teeth between the gears
to be checked, rotate the crankshaft in the operating direction
so that the wire is taken inwards.
IMeasure the crushed area of the wire with a micrometer.
Method using dial gauge
ITighten the holding bolts of each gear to specification.
IPlace the dial gauge on the tooth surface area of the gear to
be checked.
IWith the other gear in a set position, measure the dial gauge
value while moving the gear left and right.
Standard: 0.07 - 0.11 mm (0.0028 - 0.0043 in)
Limit: 0.20 mm (0.0079 in)
IIf it exceeds the limit, replace the gear and measure again.
IIf it exceeds the limit again, check for the installation condition
of the gear driving parts, wear of shaft and gear, and oil clear-
ance.

8. Install oil return pipe to the rear side of the cylinder head.
IWhen reinstalling a stud bolt, apply Three Bond 1207C (KP510
00150) to the thread of the bolt.
Disassembly
1. Remove adjusting shims and valve lifters.
Check the installation positions, and keep them to avoid being
confused.
2. Using valve spring compressor (SST), compress valve spring.
Using magnetic hand, remove valve collets.
3. Remove valve spring retainers and valve springs.
4. Remove valves as pressing valve stems toward combustion
chamber.
IBefore removing the valve, check the valve guide clearance.
(Refer to EM-58.)
ICheck installation positions, and keep them to avoid being con-
fused.
IRefer to the figure for intake/exhaust valve positions. (Intake
and exhaust valve driving cams are provided alternately for
each camshaft.)

GEAR TRAIN
Camshaft drive gear, injection pump drive gear, oil pump gear,
idler gear, crankshaft gear and vacuum pump gear.
1. If gear tooth and key have scratches or are excessively worn,
replace gear and key.
2. Check gear train backlash before disassembling and after
assembling.
Method A (Using dial gauge)
Method B (Using fuse wire)
If beyond the limit, replace gear.
Backlash:
Standard
0.07 - 0.11 mm (0.0028 - 0.0043 in)
Limit
