surface.

Use a nylon brush if deposits are hard to remove.

special tool MD998442, move the plunger through 5 to
10 strokes until it slides smoothly. In addition to eliminating
stiffness in the plunger, this operation will remove dirty
oil.
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.
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.
(5) Place the lash adjuster in container B. Then, gently push
down the internal steel ball using special tool MD998442

slides smoothly. This operation will clean the lash
adjuster’s pressure chamber.

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.
