5) If air is in lash adjuster, remove valve rocker assembly
from engine and bleed air completely.

B: AIR BLEEDING
1) Remove valve rocker assembly.
(1) Remove bolts
1through4in numerical
sequence.
CAUTION:
Leave two or three threads of bolt
1engaged to retain
valve rocker assembly.
(2) Equally loosen bolts
5through8all the way,
being careful that knock pin is not gouged.
2) Manually remove lash adjusters where air is trapped.
CAUTION:
If lash adjuster is difficult to remove manually, use pli-
ers. Be careful not to scratch lash adjuster.

3) Bleed air from hydraulic lash adjuster as described
below:
(1) While dipping hydraulic lash adjuster in engine oil,
as shown in Figure, push check ball in usinga2mm
(0.08 in) diameter round bar.
(2) With check ball pushed in, manually move plunger
up and down at one second intervals until air bubbles
disappear.
(3) After air bubbles disappear, remove round bar and
quickly push plunger in to ensure it is locked. If plunger
does not lock properly, replace hydraulic lash adjuster.
CAUTION:
Leave hydraulic lash adjuster (after air is bled) in
engine oil until it is ready for installation.

4) Using ST;
(1) Insert lash adjuster into ST, and fill ST with engine
oil. Usinga2mm(0.08 in) diameter rod, push check
ball in.

(2) With check ball pushed in, push plunger at an inter-
val of one second.
(3) Move plunger up and down until air bubbles are no
longer emitted from lash adjuster.
NOTE:
Hold hydraulic lash adjusters vertically during air bleeding.
5) Remove the rod. Push plunger to ensure that air is
completely bled out.
CAUTION:
If plunger does not properly lock (when pushed),
replace lash adjuster with a new one.

6) Fill rocker arm’s oil reservoir with engine oil and install
lash adjuster.
CAUTION:
Do not rotate lash adjuster during installation.
Be careful not to scratch the oil seal.
B2M0414
CAUTION:
When removing valve rocker assembly, keep the
assembly soaked in engine oil, or position it with air
bleeding orifice on rocker arm facing upward as
shown. This prevents oil leakage from and air entering
into the hydraulic lash adjuster. Failure to do so may
cause air to enter the hydraulic lash adjuster, causing
loss in performance.

7) Temporarily and equally tighten bolts1through4.Do
not allow knock pin to catch valve rocker assembly.
8) Tighten bolts
