(2) While lightly pushing down the inner steel ball using a small
wire, move the plunger up and down four or five times to
bleed air.
Use of the retainer facilitates the air bleeding of a rocker
arm mounted type lash adjuster.
(3) Remove the small wire and press the plunger. If the plunger
is hard to be pushed in, the lash adjuster is normal. If the
plunger can be pushed in all the way readily, bleed the lash
adjuster again and test again. If the plunger is still loose,
replace the lash adjuster.
Caution
Upon completion of air bleeding, hold the lash adjuster
upright to prevent inside diesel fuel from spilling.
(4) After air bleeding, set the lash adjuster on the special tool
(Leak down tester MD998440).
(5) After the plunger has gone down somewhat (.2 - .5 mm),
measure time taken for it to go down 1 mm. Replace if the
measured time is out of the specification.
