(1)

Immerse the lash adjuster in clean diesel fuel.

(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

mm),

measure time taken for it to go down 1 mm. Replace if the

measured time is out of the specification.
