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 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. Also, check that the
lash adjuster's height matches that of a new lash adjuster.
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.
