(3) Lightly press down on the steel ball inside using the
special tool MD998442. Remove all matter and
deteriorated oil adhered on the plunger by pressing the
tool back and forth five to ten times until the plunger
moves smoothly.
Caution
The steel ball spring’s load is extremely weak,
so if the special tool is pressed in with force,
the functions of the lash adjuster could be
damaged.
NOTE
The plunger movement must not snag at this time.
If the movement is abnormal, replace the lash adjuster.
(4) Remove the lash adjuster from the vat, and while
lightly pressing down on the steel ball, press the
plunger and removal all diesel oil, etc., inside the
pressure chamber.
Caution
Always face the oil hole on the side of the lash
adjuster toward vat A. Never face the oil hole
toward people.
(5) Submerge the lash adjuster in vat B. Lightly press
down on the steel ball inside using the special tool
MD998442. Clean the inside of the lash adjuster
pressure chamber by pressing the tool back and forth
five to ten times until the plunger moves smoothly.
Caution
The steel ball spring’s load is extremely weak,
so if the special tool is pressed in with force,
the functions of the lash adjuster could be
damaged.
(6) Remove the lash adjuster from the vat, and while
lightly pressing down on the steel ball, press the
plunger and removal all diesel oil, etc., inside the
pressure chamber.
Caution
Always face the oil hole on the side of the lash
adjuster toward vat A. Never face the oil hole
toward people.

(7) Submerge the lash adjuster in vat C, and lightly press
down on the steel ball inside using the special tool
MD998442.
Caution
Do not use vat C for cleaning. If vat C is used
for cleaning, foreign matter, etc., could enter the
pressure chamber when filling it with diesel oil.
(8) Stand the lash adjuster with the plunger at the top
position. Press down on the plunger with force, and
after it has reached the maximum stroke, gradually
return it. Then, release the steel ball to fill the pressure
chamber with diesel oil.
(9) Remove the lash adjuster from the vat, and stand
the lash adjuster with the plunger at the top position.
The plunger should not move when pressed down
with force.
NOTE
If the lash adjuster compresses, repeat steps (7) to
(9). Replace the lash adjuster if the same
phenomenon occurs even after diesel oil has been
filled in the pressure chamber (after the air has been
bled).
(10)Store the lash adjuster in the vertical state so that
the internal diesel oil will not spill out, and so that
foreign matter, such as dirt, will not adhere. Install
it onto the engine as soon as possible.

"GAOIL PUMP DRIVE GEAR/OIL PUMP DRIVEN
GEAR INSTALLATION
Apply sufficient engine oil onto the gears, align the match
marks, and assemble.
"HAOIL PUMP CASE INSTALLATION
1. Install the special tool onto the front end of the crankshaft,
and apply a light coat of engine oil onto the periphery
of the guide. If an oil seal is installed on the oil pump
case, always use a guide.
2. Install the oil pump case through the new oil pump case
gasket, and temporarily tighten the bolts other than the
oil filter bracket tightening bolt.
3. Install the oil filter bracket through the oil filter bracket
gasket, and temporarily tighten with the bolt.
4. Tighten the oil pump case at the specified torque 23
±3N•m, and the oil filter bracket at the specified torque
19±3N•m.
"IAFLANGE BOLT INSTALLATION
1. Insert a Phillips driver (shaft diameter 8 mm) by 60 mm
or more into the hole on the left side of the cylinder block
to stop the rotation of the counter balance shaft left.
2. Tighten the flange bolt at the specified torque 36±3
N•m.

Wave Pattern Observation Points
Check that the standard wave pattern appears when the stepper motor is operating.
Point A: Presence or absence of induced electromotive force from the motor turning. (Refer to the abnormal
wave pattern.)
Contrast with standard wave patternProbable cause
Induced electromotive force does not appear or is extremely small.Motor is malfunctioning
Point B: Height of coil reverse electromotive force
Contrast with standard wave patternProbable cause
Coil reverse electromotive force does not appear or is extremely small.Short in the coil
Examples of Abnormal Wave Pattern
DExample 1
Cause of problem
Motor is malfunctioning. (Motor is not operating.)
Wave pattern characteristics
Induced electromotive force from the motor turning does
not appear.
DExample 2
Cause of problem
Open circuit in the line between the stepper motor and
the engine-ECU.
Wave pattern characteristics
Current is not supplied to the motor coil on the open
circuit side. (Voltage does not drop to 0 V.)
Furthermore, the induced electromotive force waveform
at the normal side is slightly different from the normal
waveform.
