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.

Place the lash adjuster in container A and clean its outside
surface.

NOTE: 

Use a nylon brush if deposits are hard to remove.

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

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

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.
