LASH ADJUSTER

CAUTION

• The lash adjusters are precision-engineered mecha-

nisms. 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 dm

3

 (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.

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, 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.
