INJECTION NOZZLE INSPECTION
Inspection of injection nozzles requires expertise
and special equipment; the inspection must be
performed only at authorized service centers.
Operator instructions provided in this section are
only for information purpose.
When the injection pressure of the nozzle is
lowered or injection deteriorates, the exhaust gas
becomes extremely black resulting in the loss of
engine power and the engine will also make
greater noise.
Be sure to always maintain the correct injection
pressure of 150 - 160 kgf/cm
2
(2134 - 2271 psi).
Normally the exhaust gases are unstained. In case
of abrupt acceleration, black gas can be observed
for a short period of time but it turns back to
normal (unstained) immediately.
CYLINDER HEAD BOLT TIGHTENING
Removal and mounting of cylinder head requires
expertise and special equipment; the inspection
must be performed only at authorized service
centers. Operator instructions provided in this
section are only for information purpose.
When you need to open the cylinder head, loosen
the bolts in the same sequence with numbers from
18 to 1 as seen in “Figure 63”.
When mounting the cylinder head, tighten the
bolts in the same sequence with numbers from 1
to 18 as seen in “Figure 63”.
When tightening the bolts adjust the clearance first
and in the same order described first tighten with
40Nm torque and then following the same
sequence tighten 90° with angled torque meter
and once again in the same order tighten it 80° for
the last time with angled torque meter.
The bolts used in the cylinder head are single use
special extension bolts. After every removal of the
head, the cylinder head must be mounted using
new bolts.
