2. Place the lash adjuster in container A and clean its outside
surface.
NOTE: Use a nylon brush if deposits are hard to remove.
CAUTION
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.
4. 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.
CAUTION
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.
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.
6. 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.

CAUTION
Do not use container C for cleaning. If cleaning is per-
formed in container C, foreign matter could enter the pres-
sure 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.
8. 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, perform the
operations (7) through (9) again to fill it with diesel fuel com-
pletely. 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. Fit the lash
adjuster onto the engine as soon as possible.
