LASH ADJUSTER

Caution

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 five liters

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.

(3) While gently pushing down the internal steel ball using

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.
