VALVE LIFTER
Before replacing a hydraulic valve
lifter for noisy operation, be sure the noise
is not caused by incorrect valve lash or by
worn rocker arms or push
rods.
REMOVAL
1.
Remove the intake manifold and
related parts by following procedures
under Intake Manifold Removal.
2.
Remove the crankcase ventilation
regulator valve from the valve rocker arm
cover.
3. Remove the valve rocker arm
covers. Loosen the valve rocker arm
fulcrum bolts and rotate the rocker arms
to the side.
4.
Remove the valve push rods and
identify them so that they can be installed
in their original
positions.
5.
Using a magnet, remove the valve
lifters and place them in a rack so that
they can be installed in their original bores
(Fig.
26)
;
If the valve lifters cannot be removed
from their bores due to excessive varnish,
etc., it may be necessary to use a
plier-type tool or a claw type tool to
remove the
lifters.
Rotate the lifter back
and forth to loosen it from the gum or
varnish that may have formed at the
lifter.
INSTALLATION
Tappets or lifters and bores are to be
lubricated with heavy engine oil MS before
installation.
1.
aean
and install the valve lifters
in the bores from which they were
removed.
If a new lifter(s) is being
installed, check the new lifter(s) for a ·free
fit in the bore in which it is to be
installed.
Lubricate the lifter(s) and bore(s) with
heavy engine oil MS before inserting it in
the bore.
2. Install the push
rods
in their
original
position.
Apply Lubriplate or
equivalent to the valve stem
tips.
3. Position the
No.
1
piston
on TDC
at the end of the compression stroke,
