ROCKER ARM
(1) Check the roller surface. If any dents, damage or seizure
is evident, replace the rocker arm.
(2) Check rotation of the roller. If it does not ro tate smoothly
or if looseness is evident, replace the rocker arm.
(3) Check the inside diameter. If damage or seizure is evident,
replace the rocker arm.

3. When
lash adjuster, use diesel fuel
(1) Immerse the lash adjuster in clean diesel fuel.
(2)While lightly pushing down inner steel ball using t he special
tool, move the plunger up and down four or five tim es
to bleed air. Use of the special tool helps facilitate the air bl eeding
of the rocker arm mounted type lash adjuster.
(3) Remove the special tool 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 plun ger
is still loose, replace the lash adjuster.
Caution
Upon completion of air bleeding, hold lash adjuster
