The
lash
adjusters
are
precision-engineered
mechanisms. Do not allow them to become contaminated
by dirt or other foreign substances.
⦆
Do not attempt to disassemble the lash adjusters.
⦆
Use only fresh diesel fuel to clean the lash adjusters.
1.
Prepare three containers and approximately 5 dm3(30.5
quart) of diesel fuel. Into each container, pour enough diesel
fuel to completely cover a lash adjuster when it is standing
upright. Then, perform the following steps with each lash
adjuster.

The steel ball spring is extremely weak, so the lash
adjuster's functionality may be lost if the air bleed wire is
pushed in hard.
3.
While gently pushing down the internal steel ball using wire
[0.5 mm (0.020 inch) in diameter] or special tool MD998442,
move the plunger through five to ten strokes until it slides
smoothly. In addition to eliminating stiffness in the plunger, this
operation will remove dirty oil.
NOTE:
If the plunger remains stiff or the mechanism
appears otherwise abnormal, replace the lash adjuster.

Remove the lash adjuster from the container. Then, push
down the steel ball gently and push the plunger to eliminate
diesel fuel from the pressure chamber.

5.
Place the lash adjuster in container B. Then, gently push down
the internal steel ball using a wire [0.5 mm (0.020 inch) in
diameter] or special tool MD998442 and move the plunger
through five to ten strokes until it slides smoothly. This
operation will clean the lash adjuster's pressure chamber.

Do not use container C for cleaning. If cleaning is performed
in container C, foreign matter could enter the pressure
chamber when the chamber is filled with diesel fuel.
7.
Place the lash adjuster in container C. Then, gently push down
the internal steel ball using a wire [0.5 mm (0.020 inch) in
diameter] or special tool MD998442.

Stand the lash adjuster with its plunger at the top, then push
the plunger downward firmly until it moves through its greatest
possible stroke. Return the plunger slowly, then release the
steel ball and allow the pressure chamber to fill with diesel fuel.

9.
Remove the lash adjuster from the container, then stand the
lash adjuster with its plunger at the top. Push the plunger firmly
and check that it does not move.
NOTE:
If the lash adjuster contracts or moves, repeat
steps 7 through 9 again to fill it with diesel fuel
completely. Replace the lash adjuster if it still
contracts or moves after performing these steps.
10.
Stand the lash adjuster upright to prevent diesel fuel from
spilling out. Do not allow the lash adjuster to become
contaminated by dirt or other foreign matter. Install the lash
adjuster onto the engine as soon as possible.
