ten 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.
